Okay so this is going to be a long story and I’m new to this website and would really realllly love some answers. (Story starts now) so around the start of my sophomore year me and my ex gf started dating and I was planning to kiss her and it would of been my first kiss so I ride the bus get to school and I’m walking down the hallway. Feeling okay besides the fact I didn’t really wanna eat much that morning. Hen out of no where I get a extreme wave of nausea my mouth got extremely sour and watery and I ran to the bathroom and threw up and it almost looked like broth from soup very yellow. So I went home that day and took laxatives cause I also wasn’t pooping so well either. I pooped but I was still extremely nauseous and I’ve always been a healthy person. So we scheduled doctor appointments and we did stool samples blood tests and endoscopy etc and everything they tested for came back negative. But I was out of school for a month straight cause I was so nauseous to the point where I didn’t want to get out of bed because I was afraid of throwing up. I weighed 180 lbs before I got sick and dropped down to nearly 150 cause I hardly ate anything. But after that month my nausea somewhat faded away and was bareable so I went back to school and everyday my stomach was growling and was somewhat in pain and still nauseous and I still barely wanted to eat. But I’d say a month later I finally got my appetite back but still nauseous. So about half a year ago I went to a allergist and figured out I had allergy’s so I stopped eating certain foods and I’m now taking 2 allergy pills and ranitidine ( a pill to reduce stomach acid). But still I am nauseous constipated and my stomach still grows constantly and I also burp a lot till this very day please please help
