For about a week now i've been experiencing a lack of appetite, nausea, and have been bloated as well. I dont wake up hungry, i could go from morning to night without eating anything because i dont feel hungry at all and i am bloated as well so it feels like i just ate. when i do eat i end up getting nauseous afterwards and that feeling is pretty much constant until i go to bed. i also burp and have acid reflux afterwards but i feel like my whole problem cant just be acid reflux. could it be an ulcer? i dont know and its really frustrating. btw im a 17 year old girl.
