Blood sport -

When I exercise on bonk (no calories before or during endurance exercise) I can get rather loopy. My glycogen stores deplete and my thought processes can suffer. I generally do not notice these conditions. Others around me claim that I get very irritable and downright ugly on occasion. I just know that I get frustrated easily. This also happens when I miss meals or do not get enough calories. Although I do eat a sensible diet and get plenty of exercise it has been brought to my attention that I may have Type 2 Diabetes. Looking at the symptoms from the mayo clinic I can see several that I posses:

Symptoms - Type 2 diabetes symptoms may seem harmless at first. In fact, you can have type 2 diabetes for years and not even know it. Look for:
  • Increased thirst and frequent urination. As excess sugar builds up in your bloodstream, fluid is pulled from your tissues. This may leave you thirsty. As a result, you may drink — and urinate — more than usual.
  • Extreme hunger. Without enough insulin to move sugar into your cells, your muscles and organs become depleted of energy. This triggers intense hunger that may persist even after you eat.
  • Weight loss. Despite eating more than usual to relieve your constant hunger, you may lose weight. Without the energy sugar supplies, your muscle tissues and fat stores may simply shrink.
  • Fatigue. If your cells are deprived of sugar, you may become tired and irritable.
  • Blurred vision. If your blood sugar level is too high, fluid may be pulled from your tissues — including the lenses of your eyes. This may affect your ability to focus.
  • Slow-healing sores or frequent infections. Type 2 diabetes affects your ability to heal and fight infections. Bladder and vaginal infections can be a particular problem for women.

I definitely have the first two and the fourth (I wish that I had the third). So with all of the above I decided to check out my fasting blood sugar and start to track this parameter. I also think that it would be beneficial to take this fasted state reading and then do a bonk run / ride and track the fluctuations. My reading this morning was in the normal range (77). Also from the mayo clinic:

  • Fasting blood sugar test. A blood sample will be taken after an overnight fast. A fasting blood sugar level between 70 and 100 mg/dL is normal. A fasting blood sugar level from 100 to 125 mg/dL is considered prediabetes, which indicates a high risk of developing diabetes. If it's 126 mg/dL or higher on two separate tests, you'll be diagnosed with diabetes.
