I (F21) don't know what to do. My husband (M24) doesn't know what to do. This is posted with his consent. He will not gain weight at all. We first got together in 2021, and he weighed about 160lbs. He does have undiagnosed stomach issues, but every doctor we've been to just throws nausea pills at him and tells him that they'll keep his stomach in order. I have witnessed this man eat 2 bites and throw up everything in his stomach, most of it being stomach acid. Not eat anything at all and throw up continuously for an hour--hour and a half. He did get a little bit better for awhile. He stopped puking but still couldn't eat more than 3 bites of anything we made. He can eat 3 full meals a day and won't gain weight. Within the last 6 months, he's been eating nonstop and he's lost weight. He eats healthy, eats junky food, homemade food, and drinks weight gain shakes. Nothing is working though. I'm concerned he's going to die on me. Actually die. He's terrified to go back to the doctor because of the bs responses he's gotten every time he's gone. Does anyone have any advice??

I feel like going back to the doctor is our only option. But I don't know what to ask the doctor. What I need to be looking for. I'm so over my head in this, but I NEED to help him..
