Sports And Exercise: The Ultimate Challenge In Blood Sugar Control

by gary scheiner, MS, CDE Sometimes, it amazes me how smart the pancreas really is. It always seems to know what to do to keep blood sugars in range, even under the most challenging circumstances. Having an argument with your partner? It churns out some extra insulin to offset the “fight or flight” response (make that flight only, if you’re smart). Upset stomach keeping you from eating the way you normally eat? Insulin secretion drops off a bit. Can’t resist the aroma of a fresh bagel (something that, in my opinion, was forged by the Diabetes Devil himself)? Pancreas cranks out just enough to cover it. Participation in sports and exercise presents a special challenge. That’s because physical activity can affect blood sugar in multiple ways. With increased activity, muscle cells become much more sensitive to insulin. This enhanced insulin sensitivity may continue for many hours after the exercise is over, depending on the extent of the activity. The more intense and prolonged the activity, the longer and greater the enhancement in insulin sensitivity. With enhanced insulin sensitivity, insulin exerts a greater force than usual. A unit that usually covers 10 grams of carboh Continue reading >>

    I think I forgot to give Goofy his 2 units of insulin this am....ugh. Now we have to be gone all afternoon. He gets 1 unit in the evening.
    Has anyone else forgotten this? I have one other time, and it seems to me when I called the vet, it wasn't a big deal. Goofy has been controlled for quite a few years and has no problems. Same dose all this time.
    Wouldn't you know it would be on Christmas that this happens.
    Any thoughts?

    Well...seems no one was around yesterday! Do you monitor Goofy's blood sugar? how's it doing, level wise? I guess you're just back on schedule and everything is AOK?

    You did the right thing by not giving the dose at a later time, especially since you are not 100% sure that you missed the dose. In a situation like this, it's best to just wait and give the next scheduled dose as you normally would.

  • How Does Exercise Affect Insulin Sensitivity?

    Insulin is a hormone that helps the body absorb glucose, keeping blood sugar levels in balance. Insulin resistance makes it harder for glucose to be absorbed. This causes problems for muscles, fat, and the liver, as they need glucose (sugar). Over time, insulin resistance can cause high blood sugar levels and damage cells. Insulin resistance can lead to type 2 diabetes. People with insulin resistance are often diagnosed with prediabetes. They may ...

    A new study shows that the kind of meal you eat after you do aerobic exercise1 can make a big difference in helping your body metabolize blood sugar more efficiently. This is a very important issue since overweight Americans are plagued by both insulin resistance and leptin resistance – a clear path to type II diabetes. Researchers found that eating low carbohydrates following exercise improved insulin sensitivity, meaning the muscles and liver ...

Individuals with diabetes voluntarily exercise and record self-monitored blood glucose levels.

  • How Does Exercise Affect Your Blood Sugar?

    During activity, injected or pumped insulin cannot be 'shut off' like the body's own insulin, so too much glucose is taken up by both muscle contractions and the high levels of insulin, says Sheri R. Colberg, Ph.D., professor of exercise science at Old Dominion University in Norfolk, Virginia. To avoid hypoglycemia when doing physical activity, monitor your blood sugar before and after exercise. Here are some other guidelines from Colberg and the ...
