I’ve had chronic gastritis for a year now, basically when ever I have alcohol, caffeine, greasy food, spicy food, creamy food or too much sugar, I get cramps in my stomach and I throw it all up violently. Sometimes I just get the pain for absolutely no reason (like after waking up, there’s no food in my stomach to upset it, my stomach probably doesn’t like being empty either). My GP suspected a stomach ulcer and put me on acid suppressants and told me to come back if it didn’t help. One night after getting the stomach cramps and throwing up, the pain didn’t go away, it only got worse, it was late so I had to go to the ER. I was in hospital for 2 days, I wasn’t allowed to eat any thing (which probably made it all so much worse) because I had to have a ultra sound of my organs, the ultra sound showed that everything appeared normal. I then went to a gastroenterologist and got booked in for a gastroscopy, the doctor also took biopsies for cancer and celiac disease at the same time (I had neither), there was no ulcer, or any scarring that couldn’t indicate that I may have had an ulcer that healed. What they did find was that my cardiac valve (the valve at the top of the stomach) was slightly weak, which indicates that I could have gastric reflux, but there was no scarring around the valve as further evidence of this. It doesn’t feel like reflux, so I don’t think it is that. I’ve just got a sensitive stomach I suppose.
Talk to your doctor about your symptoms, ask about seeing a gastroenterologist. You say your nerves cause poor digestion? Maybe your nerves are the problem that needs to be addressed instead? Seeing a dietician wouldn’t hurt either.
I’m naturally very small, I’m 5’3 and I weight 43 kilos, the most I have ever weighed (before I got sick) was 46 kilos, I then lost 6 kilos while I was sick, it’s taking me a long time to put on just 3 kilos, and I still fluctuate below that. Some times I feel like I’d be so much healthier if I could just gain some more weight… but it’s hard, and not many people understand that it’s hard, they say “Oh I wish I had that problem”, but if they knew the half of what it was like to have the stomach problems I have I bet they would think a bit differently, generally I just tell people who say things like that to me that I’m actually quite sick at the moment… and I was even in hospital because of it. That usually shuts them up. It helps not to talk about it with people at all any way, especially about my weight, every one thinks they have answer for chronic gastritis, and/or for my weight (“just eat more pies!”, Pies are precisely the sort of thing that made me sick and loose weight in the first place!). I only talk about it in any detail with people who have medical degrees.
Sorry, I’ve rambled :P. All the advice I really have to offer is that you see a doctor and demand answers.
Good luck, I hope it works out for you :)
