E Gets an 'A' at Lowering Risk of Diabetes Complications

continued...

The researchers found that in both diabetics and nondiabetics, high doses of vitamin E greatly decreased the release of damaging substances and chemicals and reduced the amount of the repair cells that stick to blood vessel walls.


And although some researchers worry that high-dose vitamin E supplements may be harmful, the researchers found no evidence of side effects throughout the three-month study.

The current study dovetails neatly with one reported by George L. King, MD, and colleagues at Harvard Medical School, which found that high-dose E is effective at preventing and may even help to reverse diabetes complications in small blood vessels within the eyes and kidneys in people with type 1 diabetes.

"The assumption here is that its only effect is as an antioxidant, but there's quite a bit of data, which we and others have shown, that vitamin E also has effects on other systems," King says, adding that what is clearly needed is a large, lengthy study of high-dose vitamin E to test this controversy.

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
