I'm an 18 yr old female, I'll be 19 in a couple weeks. I've been experiencing these symptoms for as long as I can remember, but as I'm getting older, it seems to be getting much worse. I'm just hoping light can be shed on this.
The first symptom I experienced was extreme pain w/ gas. When I was younger, I didn't realize it was gas, I though I was just very,very hungry. I also didn't realize it was unusual. I though everybody hurt when they were hungry, and that they must just eat more than I did. The pain always kicks in a couple hours after my last meal. After about four or five hours, it becomes debilitating. I can't stand up anymore at about that time and have to crouch up.
I am also very hungry, unusually hungry I think. After eating until I'm full, even uncomfortably full, I'll be starving again w/in 90 min. or less.
I relieved those two lately by just eating constantly. I don't really eat meals anymore, I just eat all day long.
The odd thing is, I never gain weight. I never have, and I don't have any kind of exercise regime either. I eat a lot and weigh about 113 lbs. I've gone for weeks before on very poor diets and don't gain weight. I feel very confident that I could live off doughnuts and soda and not gain a pound. But I wouldn't, so don't worry.
I never loose weight either, though. That's why I really don't suspect any kind of nutrient-absorption problem. My weight is very steady. I've weighed 113 since puberty.
I'm also extremely exhausted. There's nothing wrong with my sleep at all. I sleep through the night for the full 7-9 hours, but wake up exhausted. I'm yawning all day long. I never feel refreshed. I don't even remember what refreshed feels like. All I know is this fatigue, and it's become more mind-numbing lately.
Recently I've had diarrhea almost twice a month. I feel this is probably related to stress though. It's the end of the school year and I have a lot of term work due.
I also experience rotten egg smelling gas. The first time this happened was in January. I remember trying to sleep when I got very nauseous. It lasted all night and into the next day. I felt certain I was going to vomit, and I would have had I let myself but I really didn't want to. I started belching and passing gas, the worse smelling gas ever. Every time I let it out though, a burp or otherwise, the nausea/pain would lessen slightly, so I kept it up. The smell was terrible though, and the taste of the burps in my mouth was almost enough to make me vomit anyway. The second time was about 6 or so weeks ago. The nausea wasn't as severe. Now I seem to have the nasty smelling gas every couple weeks, but without nausea.
I sweat when I eat vinegar, and always have. It's nothing profuse, just spotting on my hairline. It starts almost immediately. This is salt & vinegar chips, salad dressings, marinades; anything w/ vinegar.
Occasionally, I'll have dizzy spells. The worst one of these was a few months ago when I had to lay down to feel any kind of stability. The dizziness lasted almost all day. I get light-headed nearly every single time I stand up. Often I stand up and almost immediately fall over again because of the light-headedness and the darkness clouding my vision.
That's about it that I can recall. A lot of these might just be the way my body works, and be completely unconnected to anything or each other, but I wanted to post just to see if there's any kind of general consensus. Thanks very much for reading my too-long post.
