thanks for all advice guys. really appreicate it :)
What allmymarbles is referring to is a "Glucose Tolerance Test" which determines how much your blood sugar is rising and dropping. Even the Keotone strips you buy OTC are very accurate in determining if you blood sugar is high or low. My husband has has Type II diabetes for 16 years and his blood sugar levels are checked with blood tests. This is what the Blood Glucose Meters do, they measure your blood sugar level by you nicking your finger and getting a drop of blood into the meter, which then shows them a number. I'm sure you've seen these on TV, but you don't need one unless you are diagnosed with diabetes. Diabetics lives depend on knowing what their blood sugar levels are on a daily basis, so the blood testing has to be very accurate. An Endo is still best at doing your testing, any and all testing for this.
A definitive exam is a 6-hour test for blood sugar levels. First they test your blood sugar for a base level. They you drink some horribly sweet glop. Subsequently they test your blood sugar hourly. A simple fasting blood sugar test would not tell you much.
These are vague symptoms for hypoglycemia. I would see an Endocrinologist and have some bloodwork done.
I think there are two types of hypoglycemia. If it is reactive hypoglycemia the intake of sugar will depress blood sugar further. In the other type an intake of sugar will raise blood sugar. The latter would explain why the intake of sugar helps you. I hope other people on this forum can explain it better, since my knowledge is sketchy. I have reactive hypoglycemia.
