Type 2 – a Personal Approach to Diabetes Control

I am now 65 – was diagnosed over a dozen years ago and have maintained a pretty constant HbA1c below 7.0.  This contrasts pretty much with my very busy lifestyle and home life; starting new businesses and raising an 8 year old daughter. The majority of my business associates don’t know that I am a diabetic.

My regimen is based on simple and easy to follow rules in my diet, my exercise and my medication.   This works for me; it doesn’t necessarily work for you … I have been lucky to work with some of the best GP’s and endocrinologists below the equator.  So the first step in my program is – talk to your doctor, see him or her every three months. This is not one to do on your own!

DIET

If this is not your first visit to the ODB, you will know we are great supporters of the Glycemic Index.
Not all carbohydrates are evil is the motto of the low GI diet. As a measurement of how quickly a particular carbohydrate is used by the body, the Glycemic Index is already found on nutritional labels in Europe and Australia, but has yet to be endorsed any American organization.

Manufacturers have prepared low-GI foods and I make great use of their products.
Bread is a staple in my house and I make sure it’s a low-GI product.
That’s what’s so different about the GI, it’s not low carbohydrate, it’s more selective carbohydrate.

Foods with low GI are metabolized slower, meaning they sit in your digestive track longer and are gradually absorbed by the body. This leads to a more gradual blood glucose increase, keeping your hunger satiated longer. You feel ‘fuller’! More on feeling full later in the week.

How do I fit this into my lifestyle – in my wallet is a go/no-go list … last week I gave you my list of go foods …. now for my list of no-go

No-Go No. 1  Spuds   I have learned to swap white potatoes with sweet potatoes and yams; not to eat them when I am out.  If you must occasionally scratch your potato itch, cook them the day before in a salad and put them in the fridge overnight … it slows down the rate of digestion of the starch.

No-Go No. 2  Breakfast Cereals  I obviously don’t chow down on Coco Pops; but you may be surprised at the others in the hi-GI list; they include Cornflakes, Bran Flakes, Total, Rice Bubbles, Sultana Bran, Cheerio’s, Weet-Bix is borderline.

No-Go No. 3  Staples  Poor old potatoes, they get a pasting again [no fries and no mash] along with short grain white rice and tapioca.

No-Go No. 4  Snacks   Not what you think: the drop-em list includes pretzels, water crackers, rice cakes, the ubiquitous scone and as you would expect: maple syrup and donuts.

No-Go No.5   Fruits    The two traps for the unwary are watermelon and dates.

No-Go No. 6  Vegetables  There are two here too: parsnips and pumpkin.

No-Go No. 7  Bread   The usual culprits: white [unless modified and proudly wearing its low-GI label], bagels and French baguettes.

And, that’s not that hard to remember! Here is a full list online … David Mendosa is a diabetic treasure!

EXERCISE

This is a no-brainer!

You can prove the effect of exercise to yourself simply by checking your BGL before and after a half hour brisk walk. I sometimes even risk a hypo.

New research shows that moderate exercise, such as walking, cycling, or jogging, can significantly reduce the risk of death for people with Type 2 diabetes. This study followed over 3,300 people and correlated their level of physical exercise with mortality to find that moderate exercise reduced the chance of cardiovascular death by 9%, and more vigorous exercise reduced the total chance of death by 33%.

To people with diabetes, this probably isn’t new news. We have long been advised to pursue physical exercise, especially cardiovascular exercise, in order to improve their overall health and reduce their chance of death. This study simply adds support to the notion that physical exercise is the number one way to enhance your health and avoid the downward health spiral associated with diabetes.

Now, don’t rush off and join a gym. Healthy exercise can be as little as three thirty minute workouts a week with time beforehand to warm up and a cool down time afterwards.

I do some stretching exercises and speed walking for twenty minutes.

A couple of do’s and don’t’s: drink plenty of water and take it easy –this is meant to be moderate.   Don’t hold your breath when you feel the strain, breathe out; don’t stand still after your twenty odd minutes of speed walking, walk around slowly as part of your cool down.

You want to get into this deeply –try Professor Bob Montgomery’s book: Your Good Health –it also contains a good section on giving up smoking as well. My last puff was over 25 years ago! Bob was a pioneer in so many areas of good health.

Now that I am over 60, I make that five mornings a week rather than the minimum three whenever I can. It makes me feel good!

Starving ChinaMEDICATION

Keep in mind that drugs are not magic. If you are taking a drug for diabetes control, it is still essential that you follow a good diet and get regular exercise. These two elements of diabetes control are the pillar on which all other diabetes treatment rests.

I have a cocktail of three prescription medicines:
Metformin:  It works by helping the insulin that your body is still making work better. It also has a side effect which is very beneficial for most people with Type 2 diabetes—it makes you lose a little bit of weight by decreasing appetite. Another good side effect for some people is that it tends to lower triglycerides (certain fats in the blood), which is great if you tend to have high triglycerides.
Glibencalmide: It works by making your body produce more insulin. As you probably know, when you have type 2 diabetes, your body is able to make some insulin, but not quite enough to overcome the insulin resistance that your body has. When you take these drugs, your body is able to make a little more insulin.
Thiazolidinediones: I use a brand name called Avandia. These drugs work by helping the insulin that your body is already making work better, but they work on different parts of your body than metformin does.

Each performs a slightly different function.

I cannot stress too much that this works for me and you need to discuss dosages and oral mixes with your own doctor.

As I said, I was diagnosed as a T2 nearly fifteen years ago now, I have a heavy family diabetic history, so I guess it was inevitable …but, touch wood, the above regime has kept my HbA1c below 7.0 for the last five years. It’s not meant for you, it is meant to make you think!

Note: the cartoons are from a cool diabetic information site and the clever wit of Mike Adams and with help from Dan Berger.

Geoacaching and Strips

This has to be crazy but anything that gets me exercising has got to be worthwhile!

A friend in the States tipped me off to this blog where I found the following post:-

I want to share an inspiration I had, thanks to my son’s recent diagnosis as having type-1 diabetes . . . those little test-strip containers make outstanding micro-cache canisters!

The canisters are slightly smaller than film canisters and have a water-tight, attached lid. They are also lined with a dust-free, solid desiccant material that dries out any moisture that gets inside, so paper log pages stay dry, or get dried out if they are rained on while being logged.

Leave it to a geocacher to discover a small water-tight container and get all excited.

I tested these canisters by closing a dripping wet piece of paper into one. Over the period of a day and a half the paper was dried completely. So, I soaked the paper again. And again, the paper dried completely. I’m sure there is a limit to the amount of water the desiccant can absorb, but clearly it is enough to keep all but the most abused geocache dry for a very long time through many rainy days/months of logging. And heck, even if you are not concerned about moisture, the size and the attached lid still make these one of the best micro-cache containers I’ve ever seen (I’m not a real fan of “ultra-micros).

I am interested in trying to market these little gems with 100% of the proceeds [sic] going to support diabetes research. I just posted a set of three of these with some custom log pages on eBay. Please let me know what you think and if you have any other ideas on how to promote diabetes support with geocaching. I really appreciate the GC.com travel bug support of diabetes. I think it is exceptionally cool.

My son tests enough to generate another empty canister about every two or three days, so we probably have about 150 of these saved up right now. I expect there are other diabetic geocachers out there that could contribute to this cause as well.

What is Geocaching?

Geocaching is an entertaining adventure game for gps users. Participating in a cache hunt is a good way to take advantage of the wonderful features and capability of a gps unit. The basic idea is to have individuals and organizations set up caches all over the world and share the locations of these caches on the internet.

GPS users can then use the location coordinates to find the caches. Once found, a cache may provide the visitor with a wide variety of rewards. All the visitor is asked to do is if they get something they should try to leave something for the cache.

Now I know what to do with all my strip canisters other than give them to my 8yo daughter who incorporates them with her doll play somehow!

Shopping…My Favourite Kind Of Exercise

I don’t know about you but lately I’ve been reading a lot about the benefit of strength exercises. Now, I am the sort of person who hates the kinds of exercise most people go to the gym to do. However, I love dancing, swimming (only when the temperature is right), walking and SHOPPING! (I have a black belt in shopping).

The experts say that strength exercises will prevent us breaking bones, and delay the crippling effects of osteoporosis, which affects 1 in 3 people. Research has also shown that strength exercises can help in managing Type 2 diabetes.

Studies in the US mentioned in this months Australian ’Diabetic Living’ Magazine, showed that teenage boys, who lifted weights at least twice a week, had significantly reduced their insulin resistance. While they didn’t “give away” weight, they did reduce body fat and gained lean muscle. (Remember that we give away the things we don’t want back - if we lose something it implies we want it back :) )

It seems if we really want to do ourselves a big favour strength exercises may be the way to go… PLUS the way I see it, there’s no harm in achieving enviable 6 packs and improving many other health issues too!

I am convinced that if I go Shopping more often I will lift more weights, and therefore I too will improve my fitness… so bring on the shopping! :D

An Inspirational Athlete

I was reading a story about Adam Morrison this morning and wanted to share it with you. Adam has been living with diabetes since he was diagnosed at age 14 and has just been picked third in the NBA draft.

Adam is remarkably disciplined with his diet and diabetes management, sticking to strict meal times and constantly testing his blood glucose levels.

An article released today about Adam’s success states ”If you have diabetes, and I do, one of two things usually happens. Either it takes over your life, or you take over it.”

Congratulations Adam on your success and incredible attitude.

Lifestyle Changes Effective In Protecting Against Type II Diabetes

The evidence continues to emerge that healthy lifestyle changes can help to protect against type 2 diabetes. A new British Medical Journal study has confirmed that lifestyle changes are just as effective as taking preventative prescription drugs (and in some cases, even more effective. You can read the full article below.

Science Daily — “Changing to a healthier lifestyle appears to be at least as effective as taking prescription drugs in reducing the risk of developing Type 2 diabetes, says a new British Medical Journal study.

Type 2 diabetes is a growing problem — in England around 1.3 million people have diabetes and around 5% of total NHS resources are used for the care of people with diabetes.

Researchers from Leicester reviewed studies which measured the effects of different interventions — lifestyle, diabetes drug and anti-obesity drug — on people with impaired glucose tolerance. (People with impaired glucose tolerance have a high risk of developing type II diabetes.)

They found that lifestyle changes, e.g. switching to a healthier diet and increasing exercise to be at least as effective as taking prescription drugs. On average, lifestyle changes helped to reduce the risk of developing type 2 diabetes by around half. Lifestyle changes were also less likely to have adverse side-effects.

However, the researchers say that both lifestyle changes and prescription drug taking must be sustained in order to prevent the development of Type 2 diabetes.

The authors say that as global rates of Type 2 diabetes are likely to double by 2030, interventions to prevent the condition will have an important role to play in future health policies. The study findings have large implications for public health policy, however, the authors note that if lifestyle changes are to be truly effective more needs to be done to support people to adopt healthier lifestyles.”

Hi, I’m Sharon

Thought I’d introduce myself as a new member.  I was diagnosed 3 years ago, at the age of 43, with type 1 diabetes.  I had only known 1 person in my life with type 2 and was totally in the dark as to the difference between the two types, that is until it happened to me, having it yourself is different.  I needed to learn about the condition, what was happening inside my body, and, most importantly, how to look after myself and keep fit.
Running has always been my passion for many years, and I have completed many marathons, at first I thought I would never run again, that was until I took a grip on myself and started to learn how my body reacted to diet and running. 

I’m not saying it’s easy because it’s not always, but It’s been worth all the effort I’ve put in and I now enjoy my running more than ever.  I feel that having diabetes has taught me more about myself.

I’m looking forward to sharing my experiences of how I cope with running, insulin and diet with you.

Cycling The Way To A Cure

Today I was looking around to see what sorts of things people are doing during 2007 to raise awareness about diabetes and work towards a cure. Once again, the American Diabetes Association is running the Tour de Cure all over the United States, which they’ve been running since 1991.

The Tour de Cure is a series of events that will take place throughout the year and the focus is on supporting the ADA’s mission to “prevent and cure diabetes and to improve the lives of all people affected by diabetes”.

We’d love to hear what other events you’re involved in throughout the year so feel free to leave us a comment on this blog or make a post on the forum.

Balancing Food, Activity And Insulin

Healthy eating is essential to managing diabetes, whether you take tablets, insulin or no medication.

Finding The Balance

To manage your blood glucose levels, you need to aim for a balance between the amount of food you eat, the physical activity you do and the insulin you take. You will need to consider the timing, amount and type of carbohydrate foods you eat, as well as the timing, amount and type of the insulin you take. Your dietician can provide advice on an eating plan that’s best for you.

It isn’t always easy to find the right balance, but regular blood glucose testing will help. Your diabetes educator or doctor will tell you more about testing (also refer to our post about Glucose Monitoring).

Carbohydrates

Carbohydrates provide energy and good nutrition.

The timing – why is it important?

The aim of good diabetes management is to match your insulin intake with the carbohydrates you eat. There are many different types of insulin with different actions such as the time they start to take effect, reach their peak and run out. It is important to eat a regular and consistent amount of carbohydrate containing foods throughout the day. If your carbohydrate meal plan is regular from day to day, it will be a lot easier to manage your blood glucose levels.

The amount – too little or too much?

If you eat more carbohydrate than usual, without increasing your physical activity or your insulin, your blood glucose level can rise too high (hyperglycemia). If you eat too little carbohydrate or skip a meal, your blood glucose level can drop too low (hypoglycemia or hypo). That’s why you need to find the right balance of carbohydrate containing foods.

There is no ‘one size fits all’ as the amount of carbohydrate that’s right for you will depend on your age, body size and how physically active you are. Some people use carbohydrate ‘exchange’ or ‘serve’ lists to work out the amount of carbohydrate they eat and keep it consistent day to day (one carbohydrate ‘exchange’ contains 15 grams of total carbohydrate). Reading food labels or carbohydrate counters can help you calculate the amount of carbohydrate in various foods.

The type – why does it matter?

The Glycemic Index (GI) is a ranking of the effect a carbohydrate food has on your blood glucose levels. For example, foods with a low GI raise blood glucose levels more slowly than foods with a high GI. Knowing the GI of the foods you eat can help you to manage your blood glucose levels. Including carbohydrate foods that have a low GI may help to prevent hypos between meals, whereas foods with a high GI are useful during prolonged physical activity. But remember, eating too much of any carbohydrate will still raise your blood glucose levels.

Alcohol - Can I Drink It?

Most people using insulin can drink alcohol in moderation. Be aware though that alcohol can increase the risk of a hypo. The common symptoms of a hypo (weakness, shaking, dizziness, sweating and lack of concentration) can be similar to the behavior of someone who is drunk, so there is a risk that your hypo may go unnoticed if no one knows you have diabetes.

A hypo can also be harder to treat after drinking large amounts of alcohol. In General, The Maximum Amount Of Alcohol Recommended For A Person With Diabetes Is:

 • 1 standard drinks a day if you are female

 • 2 standard drinks a day if you are male It is also recommended you have at least 2 alcohol-free days a week. (One standard drink is equal to 285mL regular beer, 425mL low alcohol beer, 100mL wine, 60mL fortified wine or 30mL spirits).

Here Are A Few Tips To Reduce The Risk Of An Alcohol-Related Hypo:

 • Make sure someone with you knows you have diabetes

 • Drink in moderation

 • Always eat some form of carbohydrate when drinking alcohol*

 • Eat a low GI snack before bed

 • Test your blood glucose level before bed

 • Wear some form of diabetes identification (eg: MedicAlert®)

*if there are no carbohydrate foods available, use a standard soft drink or fruit juice when mixing drinks. Otherwise, use a low joule (diet) soft drink as a mixer.

Physical Activity - How Does It Help?

Regular Physical Activity Helps To:

 • Improve insulin sensitivity which makes insulin work better and lowers blood glucose levels

 • Control blood fats (cholesterol and triglycerides), blood pressure and body weight.

 • Increase bone strength and improve your general sense of well being. How Can I Avoid An Exercise-Related Hypo? Physical activity can cause your blood glucose levels to drop low. People taking insulin need to plan ahead before physical activity.

Here Are Some Tips To Reduce The Risk Of Hypos Due To Physical Activity:

 • If your blood glucose level is below 6 mmol/L, you may need an extra carbohydrate snack before starting your activity.

 • If you are being active for a long time, make sure you have some carbohydrate food or drink during your activity.

 • Adjusting insulin may also help to reduce your risk of a hypo. Discuss with your doctor or diabetes educator how to adjust your dose depending on the type and length of your activity.

 • Testing your blood glucose level before, during (if exercising for a long time) and after your physical activity will help you to find the right balance.

 • Physical activity can lower blood glucose levels for up to 24 hours afterwards. Having more carbohydrate at your next meal or snack and a low GI carbohydrate containing food before bed can help. Adjusting your insulin at bedtime may also be an option – discuss this with your doctor or diabetes educator.

Sometimes, physical activity may cause a temporary rise in blood glucose levels, particularly if the activity has been competitive or stressful. Despite this rise, you need to have adequate carbohydrate containing foods afterwards, as a delayed hypo may still occur. People with Type 1 diabetes are generally discouraged from strenuous physical activity when blood glucose levels are above 15 mmol/L as it can cause levels to rise even further.

Other Issues

People with diabetes also need to consider factors relating to their feet, eyes, kidneys and heart, so it is important to talk to your doctor before starting any new physical activity program.

Exercise and Health Myths

Hi All

I recently spent a weekend at the Golden Door health retreat at the Hunter Valley. It is an amazing place to go if you want some help improving your lifestyle. While I was there I gave 3 lectures.
1. How Glucose and Insulin work in the body and how exercise affects them.
2. what is the Glycemic Index
3. Flow - the key to performance.

Following the talk on exercise a lot of people asked me whether certain myths were real or not. I was astounded as to some of the things that people believed about exercise.

In this post I dispell some to the most common myths with health and exercise. For more myths about diet and exercise go to my website www.energyfactory.com.au and click on “Articles on Glucose Control and Health”

MYTH: If you stop exercising your muscles will turn to fat
This is one of the more ridiculous fallacies out there. Muscle and fat are two
completely different tissues; one cannot turn into the other. It is about as logical
as saying that an apple will turn into an orange.
What often happens is that when we stop exercising we usually continue to eat
the same amount of food. The result is more body fat and smaller muscles. This
is due to the calorie excess and the lack of stress on the muscles. Muscles
respond to the pressure we put on them, if they are not being forced to work they
shrink.
“His muscles have turned to fat” is usually a phrase used to describe retired
professional sports people such as footballers. When they are playing they are
expending a huge amount of energy so they need to eat large amounts of food.
However when they stop playing they still eat the same amount and put on truck
loads of body fat.
Remember: Don’t stop exercising, but if you do have to because of some reason
(sickness or injury) lessen the number of calories you eat.

MYTH: You only start burning fat after 20 minutes of exercise
This is a very bad message to send out to people as they get the impression that
short bouts of exercise are not beneficial. Our metabolism does not have an on
or off switch. Except in very extreme circumstances, you are always burning a
combination of fat, carbohydrate and protein all the time, whether you are
running for a bus, strolling on the beach or moving furniture.
Breaking your exercise up into smaller bouts (10 – 20 minutes) can actually be
more beneficial for weight loss as you can exercise at a higher intensity for that
time. Fifteen minutes in the morning and fifteen minutes at night is a great way to
start dropping the kilos.
Remember: Any amount of exercise is a good amount.

MYTH: You burn more fat by exercising gently
At a low intensity (slow walk) you do burn a high percentage of fat; however your
calorie expenditure is very low. As you increase the intensity of the exercise (fast
walk or jog) you do decrease the percentage of fat that you burn but the total
amount of calories that you use up increases significantly. The result is that the
higher intensity exercise burns a greater amount of body fat. A bonus is that
following intense exercise you stimulate something called EPOC which is
“excessive post-exercise oxygen consumption”. After intense exercise your
metabolism is elevated and you burn more calories, resulting in greater fat loss. It
is true you can get skinny lying on the lounge.
People get so caught up with trying to find the right intensity to exercise at. They
try to get their heart rate in the fat burning zone. Forget the fat burning zone, just
get out there and move. Of course, don’t just leap into a high intensity exercise
program, build up to it slowly and always consult your doctor before beginning.

Blood Glucose Monitoring

9.1 Why Is It So Important To Test My Blood?

Self-blood glucose monitoring (SBGM) is a valuable diabetes management tool, which enables people to check their own blood glucose levels as often as they need to or as recommended.

Regular testing of your blood glucose level (BGL) can reinforce your healthy lifestyle choices as well as inform you of your response to other choices and influences.

Importantly, BGL pattern changes can alert you and your health professionals to a possible need for a change in how your diabetes is being managed.

Testing your BGL’s will help you to:

• Develop confidence in looking after your diabetes.
• Better understand the relationship between your BGLs and the exercise you do, the food you eat and other lifestyle influences such as travel, stress and illness.
• Know how your lifestyle choices and medication, if used, are making a difference.
• Find out immediately if your BGLs are too high (hyperglycaemia) or too low (hypoglycaemia), helping you to make important decisions such as eating before exercise, treating a ‘hypo’ or seeking medical advice if sick. (For more information refer to Diabetes Australia’s individual fact sheets on Physical Activity, Hypoglycaemia and Sick Days about these topics).
• Know when to seek the advice of your diabetes health professional about adjusting your insulin, tablets, meal or snack planning when BGL goals are not being met.

How Do I Test My Blood?

You will need a blood glucose meter, a lancet device with lancets and test strips. The finger in pricked with a lancet to obtain a very small drop of blood which is then applied to a test strip placed in the meter. The results are displayed within seconds.

Blood glucose meters are usually sold as kits giving you all the equipment you need to start. There are many different types, offering different features and at different prices to meet individual needs. Most of these are available from Diabetes Australia, pharmacies and some diabetes centres.

A diabetes health professional such as diabetes educator can help you to choose the meter that’s best for you. Your diabetes educator will also give you all the information you need about how, where and when to test your blood glucose levels (BGLs) and work with you in planning a routine that works for you and the life you lead.

What Do I Aim For?

Successful management of diabetes is all about aiming for a careful balance between the food you eat, how active you are and the medication you take for your diabetes. Because this is a delicate balance, it can be quite difficult to achieve ideal control all the time.

For some people, the ranges will vary depending on the individual and their circumstances. While it is important to keep your BGLs as close to a normal or non-diabetic state as possible to prevent complications, it is equally important to check with your diabetes educator or doctor for the range of blood glucose levels that are right and safe for you. Therefore the following information should be treated only as a general guide.

Targets For Glycaemic Control

Risk of hypoglycaemia
(low blood glucose) Less than 3.5mmol/L*  - if insulin or certain types of tablets are used, but does not apply to other tablets or where blood glucose is controlled by meal plans alone
Normal levels 4-6mmol/L* before meals **
4-8mmol/L* after meals **
Ideal levels 4-6mmol/L* before meals
Up to 8mmol/L* after meals **
Moderate levels 6-7mmol/L before meals
Up to 11mmol/L* after meals **
Above target levels More than 7mmol/L* before meals
More than 11mmol/L* after meals**

*In Australia blood glucose levels are measured in mmol/L (millimoles per litre). In some other countries the unit of measurement if mg/dL (milligrams per decilitre).

**Two hours after starting the meal

Targets for glycaemic control taken from Diabetes and You – the Essential Guide, published by Diabetes Australia 1999, revised 2002.
Who Is At Risk Of Low Blood Glucose (Hypoglycaemia)?

• People who are using insulin or those taking diabetes tablets which increase their own insulin production are at risk as both have the effect of lowering blood glucose. They can therefore cause hypoglycaemia (low blood glucose) when BGLs are less than 3.5mmol/L. (Note: Hypoglycaemia can occur at higher BGL levels in children and people who have had higher BGLs for a long time).
• People whose diabetes is managed by lifestyle alone or with other types of diabetes tablets which do not increase their own insulin production, are not at risk of hypoglycaemia.

Are High Blood Glucose Levels Dangerous?

Sometimes you may get a higher BGL reading than usual and you may not be able to figure out the reason. When you are sick with a virus or flu, your blood glucose levels will nearly always go up and you may need to contact your doctor, especially if ketones are present. However, it is only when BGLs are consistently higher than they ought to be over weeks or month that the damage-causing complications can occur.

What Causes Glucose Levels To Go Up And Down?

There are a number of common causes for glucose levels to increase or decrease. These include:

• Food – time eaten, type and amount of carbohydrate (eg: bread, pasta, cereals, vegetables, fruit and milk)
• Exercise or physical activity
• Illness and pain
• Diabetes medication
• Alcohol
• Emotional stress
• Testing techniques
• Other medications

When Should I Test?

Your diabetes health professional will help you decide how many tests are needed and the levels to aim for.

You will also be advised to record all your tests. Even though your meter may have a memory, it is important to keep a record of your readings in a diary and to take this with you to all appointments with your diabetes health professionals. Most meters on the market have software which will allow you to download your records in different formats such as graphs and charts. Even if you do this, it is still helpful to keep a diary, not only for your tests but also details of your daily activities, the food you eat and other relevant information. This will provide both you and your diabetes team with important information in deciding if and how your treatment may need to be adjusted.

Ask your doctor or diabetes educator about how you can use a diary to help you to better manage your diabetes.

A Guide For People With Type 1 Diabetes

• Testing at least three to four times a day is recommended. However many people with Type 1 diabetes do test more often, such as those using a pump (CSII – continuous subcutaneous insulin infusion).
• Test before breakfast (fasting), before lunch, before dinner and at bedtime.
• Test occasionally between 2am – 3am (overnight levels).
• Test 2 hours after any meal.

Test more often when you are:

• Being more physically active or less physically active
• Sick or stressed
• Experiencing changes in routine or eating habits eg: travelling
• Changing or adjusting insulin
• Experiencing symptoms of hypoglycaemia
• Experiencing symptoms of hyperglycaemia
• Experiencing night sweats or morning headaches

A Guide For People With Type 2 Diabetes

• Test once or twice every day, changing the time of day at which your test is done or as directed by your doctor or diabetes educator.

• Suggested times to choose from are:

o Before breakfast (fasting)
o Two hours after any meal
o Before bed

If your diabetes is stable, this may be reduced to one or two tests a day, two to three times a week.

You may need to test more often when you are:

• Sick or stressed
• Experiencing changes in routine or eating habits eg: travelling
• Changing your medications and/or insulin
• Being more physically active or less physically active
• Experiencing symptoms of hypoglycaemia
• Experiencing symptoms of hyperglycaemia
• Experiencing night sweats or morning headaches

What If The Test Result Doesn’t Seem Right?

If you’re not convinced that a result is correct, here’s a suggested checklist:

• Have the strips expired?
• If the strip the right one for the meter?
• Is there enough blood on the strip?
• Has the strip been put into the meter the right way?
• Have the strips been affected by climate, heat or light?
• Did you wash and thoroughly dry your hands before doing the test?
• Is the meter clean?
• Is the meter too hot or too cold?
• Is the calibration code correct?
• Is the battery low or flat?

All meters will give a different result with a different drop of blood. As long as there is not a big difference (more than 2mmol/L) there is not usually cause for concern.

The accuracy of all meters can be checked with meter-specific liquid drops called control solutions. These are expensive, have a short shelf life and only last a few months once opened. However your diabetes health professional or pharmacy may be able to do this for you at no charge.

What Is Glycosylated Haemoglobin (Hba1c) Test?

The HbA1c test shows an average of your blood glucose level over the past 10-12 weeks and should be arranged by your doctor every 3-6 months. The measurement is expressed as a percentage (%) not as mmol/L like the tests you do on your blood glucose meter.

Is The Hba1c The Same As Testing Your Own Bgl’s?

No, the HbA1c test doesn’t show the highs and lows that your home testing shows. Therefore it does not replace the tests you do yourself but is used as an added tool in giving the overall picture of your blood glucose management.

What Hba1c Do I Aim For?

The goal for most people with diabetes will be in the 6.5% to 7% range however this may need to be higher for children and the old and frail. Your doctor will advise.

How Does It Work?

A glycated haemoglobin test is possible because red blood cells (RBC) are continuously being made by your long bones and released into your circulation. When these cells are released, they pick up a percentage (5) of the glucose in the blood stream at that time.

Each RBC lasts about 120 days. Therefore any blood sample will have a range of cells released over the previous 120 days with different amounts of glucose attached. The HbA1c test if able to work out the average.
