Question of the Month: August, 2002
Dear Dr. Laule,
I thought I had hypoglycemia. I get weak and feel really shaky when I eat
sugary things, and I have to carry a granola bar with me to eat so I can feel
better when I have those spells. My doctor drew a blood sugar after I had not eaten
all night, and felt fine. He said the blood sugar was normal so I don't have
hypoglycemia. Wouldn't it be better to draw the blood sugar while I felt bad,
like after I'd eaten some sugar? What do you think is wrong with me? What can I
do to help me feel better? MT, Arkansas
Dear MT:
Science has gained a lot better understanding of hypoglycemia in the last 5-6
years. Some great studies out of Stanford Medical School in California have
demonstrated the link between hypoglycemia, type II diabetes, and high serum
insulin levels. You didn't say whether or not you have diabetes in the family,
but if you do, your odds are even higher that your hypoglycemia is actually
based on having higher than normal insulin levels. The underlying problem is
called "peripheral insulin resistance," and I will explain this more
in a moment.
Determining hypoglycemia from a blood test is difficult, and actually a fasting
blood sugar will give very little information. The physicians at Stanford have
developed a very elaborate protocol for determining the condition of insulin
resistance. A 5-hour glucose tolerance test with insulin level determinations
at each interval is helpful, though not perfect. For screening, a fasting
glucose and insulin followed by a two-hour postprandial (2 hours after eating)
glucose and insulin test catches some people with hypoglycemia. I recently saw
a patient whose insulin level at one hour after drinking the sweet drink for a
glucose tolerance test was 245. It should be around 20-30. At the two-hour
blood draw her blood sugar had dropped to 40, which is quite low. But her
symptoms were the worst at one hour, when her blood sugar was 144. One small
study showed that people with symptoms of hypoglycemia had their symptoms occur
when the insulin levels went up, not when the blood sugar dropped. I've even
had one of my patients report being told by her doctor that hypoglycemia was
not a real disease, it was a "designer disease," because he could
never catch a low blood sugar.
Most of the time I make the diagnosis by the patient's history. I was taught in
medical school that 90% of the diagnosis comes from listening to the patient.
The laboratory then only confirms what you pretty well already know from taking
a history. Sometimes I do lab, and sometimes I just don't feel the need, since
most of the treatments I recommend are nontoxic and quite safe.
The mechanics of the blood sugar drop are this: The receptor for insulin on the
surface of the muscle cells and the brain cells of the body erodes from genetic,
dietary and environmental factors, and the insulin can no longer readily attach
to it to usher the glucose from the blood into the cells where it is used as
fuel for metabolism. The body has feedback systems, so when the cells are still
starving after you've eaten sugar and the blood sugar is getting higher and
higher, the pancreas gets a message to keep sending out more and more insulin
until it finally overcomes the resistance at the cell receptor level. Then,
with the body flooded with excessive insulin, the blood sugar plummets. The
fact that the cells are starving for glucose, even while there is plenty in the
blood, is part of the reason why you have sugar cravings. Eating a low
carbohydrate diet, and plenty of protein which the body can turn into glucose
more slowly will give a steadier supply and reduce the need for the pancreas to
put out massive amounts of insulin. Complex carbohydrates also slow down the
process, as will eating numerous small meals during the day. A recent study
showed that women who ate 250-300 calories at a time, multiple times per day,
did not have any excessive insulin rises from this eating pattern. DO NOT go
with the diets that recommend only protein and fat, and no carbohydrates.
Colorful fruits and a high variety of vegetables provide too many health
benefits in addition to the carbohydrates they provide. Eating simple sugars,
fruit juices, and white, refined sugar and flour are the things that elevate
the serum insulin. Check out the term "glycemic index" on the
internet, and you will learn more about diet.
One of the safest and most wonderful treatments for hypoglycemia is chromium,
which is a modulator of blood sugar levels - in other words, it brings high
levels down, and low levels up. Because some people with a family history of
diabetes or hypoglycemia do not have enough of the enzyme to convert dietary
chromium into the active form called Glucose Tolerance Factor (GTF), I cut
straight to the chase so to speak, and recommend GTF chromium. This is readily
available in health food stores. In addition, some people with sugar handling
problems also have had problems with Candida and other yeasts, to the degree of
developing highly symptomatic allergies to the yeasts, so I recommend a
yeast-free form of GTF chromium. This form costs a little more, but I think
it's worth it to find out if the chromium is going to help you. I've had people
take a yeast derived GTF, and feel very bad on it. They then think it was the
chromium and refuse to take any more of something that in actual fact could be
very helpful to them. Once you have established that the GTF form works, then
you can try the less expensive forms of yeast derived GTF, and even chromium
picolinate. The dose I generally recommend for someone with a lot of symptoms
of hypoglycemia is 200 mcg., one or two twice daily, with or without food.
There are other treatments, but I would not recommend these without knowing a
little bit more about you. The yeast free GTF chromium is safe and an excellent
place to start, and for many people the only treatment they need.
I hope you find this helpful.
To your good health and joyful living,
Alice R. Laule, M.D.
