So lately during exercise I get light-headed, my vision gets blurry, my muscles start to shake under any amount of stress, I feel faint and a little dizzy. I tire rapidly and can't recover easily. My blood glucose has never been under 80, and usually it is in upper 90s. When I consume an excessive amount of sugars however this problem seems to go away. I ate two large table spoons of honey the other day and it solved my issue. The problem is I have to keep eating every two hours or my blood sugar crashes again. Also I'm slightly overweight so I can't be eating 40 grams of sugar every two hours. What could be causing this problem? I have an unrelated blood disorder, but my doctor said it can't cause any of these issues. My liver is healthy, pancreas enzymes don't help, thyoird levels are very good.. I have slightly elevated cholesterol which is probably from eating 6 eggs a day.
