I’ve been having issues with my appetite and eating.

I get full so fast... like after a couple bites I feel like my stomach is going to burst. Then about a couple hours later I’ll get hungry again and try to eat but get full after a couple bites... then I get hungry again. (Literally the feeling that I can not eat anymore or I’ll throw up)

Usually I eat like 2-3 times a day with occasional snacking. But I’m just losing weight now. I only weigh maybe 104 pounds now, my BMI is around 15 which is underweight for my height which I’m over 5’9.

I’m wondering if there are some type of pills that increasing your appetite?
