I'm hungry all the time and if I don't eat, I get sick...nauseous, dizzy, light headed due to low blood sugar (I'm hypoglycemic). I'm not pregnant, my thyroid is good, my sugar is good as long as I eat, blood pressure is good, my heart is good, and I'm not on any medication. I am overweight and I try not to eat all the time, but I have to give in when I start feeling ill. Anyone know what could be causing this? Doctors can't figure me out. All tests come back normal except for: I have seizure disorder (absence--no I don't take meds because I had horrible reactions to 4 different meds and my doctors are scared to try anything else), sleep apnea, hypoglycemia, and ulcers. Any ideas?? Thanks!
