Hypoglycemia Forum - Thyroid? Hyopthyroid? Or Hypoglycemia?

For 8 years I have had difficulty in my life that has been diagnosed as everything from chronic fatigue to adhd to generalized depression and more. My symptoms seemed to stem from foods I ate or low blood sugar reactions. Doctors told me I was hypoglycemic at a very young age, maybe 17, and just told me to stay away from sugar and eat an extra meal. Needless to say I did this for years but I still had dizziness, loss of concentration, shakiness, fatigue, even fainting spells, shakes, and the like. A friend of mine, who is diabetic, was asking me if I monitored my sugar at all. I said no because doctors always told me just to eat more. However it seemed the more I ate, the worse my symptoms became. I could eat a balance meal and 30 to 45 minutes later I was feeling sick, dizzy, and yawning and having to nap.

My friend let me borrow her glucometer and showed me how to test my blood sugar. I started making note of my bs levels when I was feeling shaking and unable to focus or stand up and when I was feeling ok. I tested before and after meals, waking bs levels, and before bed and kept good records. I noticed that after a well balanced meal my bs would never get above 100 an hour after a meal but then 45 minutes later would drop to around 80 ... By the time my bs gets to 75 or lower I start to fall apart. I have mood swings, I get very tired, I start to tremble, I cant focus or concentrate. When I eat something I get a bit of a head rush and start to feel better.

According to standards however. Hypoglycemia is 50 or below and that my numbers are considered normal (between 70-100). How can this be? All my life I have been feeling like this. This horrible feelings. I dont drink alcohol or take any medications. I try to eat right but i'm not exactly a perfect eater but I don't eat junk either. I try to have balanced meals when I can. All of my symptoms are in line with hypoglycemia. The rapid drop in my bs I can feel. I can feel the shakes coming on. I know when I need to eat and this is several times a day.

Someone suggested that what I might be experiencing is not hypoglycemia but a thyroid problem. That I may be overproducig insuline or something to that effect. Looking up information on hypothyroidism I see the symptoms are very similar.

Does anyone have any information on thyroid problems? Could this be my problem? I really find it hard to believe that how I feel is normal. Just because my readings are normal I know how I feel and have felt for years. Since I was 17 (i'm 29 now) and I know that while I may not be hypoglycemic according to numbers, I know that there is definatley something wrong. How do I get a doctor to listen and not just dismiss my symptoms? Should I see a specialist of some kind?

Thank you for any advice.
