Weight loss

Hello, this is my second post regarding my weight loss. I asked in my previous post about foods that can help me gain weight and have been trying them but sadly still no result.

Im a 174cm tall 21yrs old male. My GERD got really severe back in November 2024, it also lead to the diagnosis of EoE and recognizing that my LES is nonfunctional (around 2 months ago). I have been on 6FED for a month and my symptoms overall have improved a lot except for chest pain which could be a result of my Hiatal hernia or EoE, who knows.

Before all of this i was 66kgs with decent muscle mass and very little fat. Now I’m 57kgs even though i eat till I’m full. Should i see my gastroenterologist again ? Could this be another disease or condition ? Or is it just that my calorie intake isn’t sufficient ?

This is making me depressed, i just cant catch a break, one thing subsides and another rises. This is really unhealthy and everyone i see gets shocked that I’m so thin right now, i hate that. Im trying my best but it isn’t working.
