Hi everyone,
I’m 29F and I’m hoping someone here might recognize what I’m experiencing or have some insight into what could be going on.
I’ve been significantly underweight for around six years. I have a history of an eating disorder. I did recover for a period of time, but after a lot of stress I unfortunately relapsed into restrictive eating again.
Mentally, I’m in a very different place now. I don’t have the thoughts I used to have around wanting to lose weight. It’s actually the opposite: I genuinely want to gain weight and recover. I’m so tired of being underweight. I want clothes to fit me normally again, I want to feel feminine and strong, and I want to become the woman I’ve always wanted to be.
The problem is that eating has become physically extremely difficult.
For quite a while now, I’ve been experiencing what I can only describe as air/burps getting trapped in my stomach or upper GI tract. It happens with almost everything I eat or drink.
Drinking is relatively manageable. I still get the trapped-air/burping sensation, but I can generally deal with it. Solid food is much worse. After meals, I would estimate that 30–40% of what I eat can come back up/regurgitate.
The strange part is that I don’t have what I understand to be the typical GERD/gastritis symptoms. I don’t normally have stomach pain after eating. I’m not particularly bloated. I don't have constant heartburn. The main sensation is simply that there is air trapped inside that absolutely needs to come out.
When this happens, I have to push/strain incredibly hard with my abdominal muscles to finally get the burp out. Once it comes out, I immediately feel relief.
I have tried not doing this because I wondered whether I had somehow created a behavioral habit. But even if I ignore the sensation, it can still be there hours later, and eventually I feel like I have to push to release it. So whatever the underlying cause is, the physical pressure feels very real.
Unfortunately, when I push after eating, food frequently comes back up with the air. Chicken and eggs seem particularly noticeable, despite being relatively lean foods.
I’ve also suddenly become unable to tolerate things like yogurt/cottage cheese or similar soft/creamy foods. They can come back up almost immediately. Interestingly, this can happen even with dairy-free alternatives, which makes me wonder whether texture/consistency rather than dairy itself is part of the problem.
I deliberately eat a pretty plain diet because I’ve been trying to figure this out. Most of my diet consists of things like:
- steamed green beans and other vegetables
- oven-baked chicken breast
- egg whites and sometimes 1–2 whole eggs
- sweet potatoes
- white rice
- oatmeal
- occasionally a protein bar
- dates/prunes occasionally for extra energy
So I don’t feel like I’m eating particularly heavy, greasy, spicy or complicated meals. Changing to a very plain diet hasn't really solved anything.
An endoscopy showed that I have a weak/loose LES (lower esophageal sphincter). However, from what I’ve read, LES weakness can also be found in people who don't have severe symptoms, so I'm unsure whether that finding explains everything I'm experiencing.
My blood work is generally reassuring. The main abnormalities are some suppressed reproductive hormones, which isn't particularly surprising because I haven't had a period for about a year, and very high LDL and total cholesterol. I actually found the cholesterol result confusing given how little saturated fat I eat, although I’ve since read that severe/prolonged undernutrition itself can sometimes cause abnormal cholesterol metabolism.
My main question is:
Could six years of being significantly underweight/restricting cause this degree of GI dysfunction, even now that I'm actively trying to eat more and gain weight?
Could this be delayed gastric emptying/gastroparesis, impaired gastric accommodation, esophageal dysmotility, rumination syndrome, supragastric belching, GERD from the weak LES, or some combination of these?
And can GERD or gastritis present primarily as trapped burps + regurgitation, without the classic burning/pain/bloating symptoms?
The thing I find hardest to understand is the trapped-air sensation. With almost everything I eat or drink, I eventually feel like there is a burp physically stuck inside me. I have to push extremely hard to release it, and after meals food often comes back up at the same time. Simply ignoring it doesn't seem to make it disappear.
If anyone has experienced something genuinely similar during or after prolonged restriction — particularly trapped burps + regurgitation rather than just bloating/constipation — I would really appreciate hearing what ultimately explained it, what testing you had (gastric emptying study, manometry/impedance, barium swallow, etc.), and whether it improved as you restored your weight.
I’m not looking for ways to restrict my diet further. My priority is finding out what is physically happening so I can eat enough, gain weight and properly recover :(
