It : It sounds like you went over 24 hours without eating, which could certainly cause low blood sugar. This, combined with your medication regimen could have caused this extreme fatigue. If diabetes runs in your family, your risk of developing the disease is higher. However, experiencing hypoglycemia does not necessarily mean you have diabetes. Diabetes is diagnosed by blood glucose tests that show a trend of high blood sugars in the blood plasma (over 126). It is manifested by high blood sugar in the blood and low performance of Insulin (which is produced by the body to lower the blood sugar). Symptoms of high blood sugar include extreme thirst/hunger, blurred vision, frequent urination, dry mouth, poor wound healing, recurrent infection and fatigue. See your doctor if you notice any of these signs of high blood sugar.

Lots of medications: You seem to be on many different types of pay medication, including ones that in combination could increase the risk of bleeding or high blood pressure. It is best to see your provider, and if you are not satisfied, seek a second opinion.
