Extreme bloating on an empty stomach and persistent poor appetite

22F 5’2 100lbs taking Aurovela combined birth control pills daily, topamax 50mg for migraines daily, lexapro 5mg for anxiety daily, Fioricet as needed for migraines (around once a week). Diagnosed with Migraines with no aura, generalized anxiety, iron deficient anemia (taking 65mg iron pills as well as multivitamins).

I noticed I’d get bloated super huge even tho I’d be on an empty stomach. I’d literally be starving but look pregnant. Additionally, my appetite has been terrible for most of life but especially recently like the past couple of months. I would eat one meal and maybe a snack and be full for the whole day.

Brought this up to my primary doctor like a year ago and they thought it might be GERD and had me on omeprazole and track what I ate. I still am tracking what I’m eating and there aren’t any patterns since I eat pretty similar meals, it seems pretty random. The omeprazole didn’t seem to do much so I am off it now after the 3 months of taking it. She also had me get an abdominal ultrasound to rule out Mono and a couple other things but the ultrasound came out normal.

Brought up some type of period related issue to my OBGYN 6 months ago since i know those can cause large bloating and she put me on birth control but didn’t want to do any other tests yet. I think it’s been helping since I haven’t gotten that huge bloating since but still have the poor appetite.

Any advice would be greatly appreciated :)
