Bill202 said Would drinking something like Gatorade during excercise be absorbed quickly enough? Am wondering how diabetic guys manage this. Thanks!
Gatorade contains 14 grams of carbs. Since it is a liquid, absorption occurs quickly. Gatorade can be used by diabetics to prevent hypoglycemia while exercising.
Another cause of sudden exhaustion that occurs with endurance activities is the "bonk" or "hitting the wall". Bonking is cyclist's slang for the exhaustion that occurs when glycogen is depleted. There are many articles on the Net about diets that help prevent bonking. You just need to Google bonk.
Medical problems can cause exhaustion. Some of these being anemia or undiagnosed lung or heart disease.
Diabetics on insulin or taking oral medications can develop hypoglycemia when exercising. I do not know if this occurs in pre-diabetics exercisers since they are not on medications that lower blood sugar. Pre-diabetics with extreme insulin resistance and not on diabetic medications can develop hypoglycemia after prolonged fasting. You can use a Visual Test Strip to check your glucose level when the exhaustion occurs. This will tell you if the exhaustion is from hypoglycemia. I have diabetic friends that check their sugars when exercising.
Hope this helps
