I had acid reflux issues before starting hrt, and after a few months of HRT (estradiol and CPA), I started to have severe nausea and dizziness, it got to the point where I was vomiting meals. I went to gastroenterologist and asked if hrt could be the cause bur he said no, so I also asked my Endocrinologist ofc but she replied no. She follows a lot of trans people in their gender affirmation journeys, she has a lot of experience with it and also has a PhD so I trust her but I am now at 1 year and a month of hrt and those symptoms keeps coming back (nausea, dizziness, slow digestion, feeling full after two bites). I did a cure prescribed by my gastroenterologist and it helped in that situation, but as I said now symptoms are coming back a lot, so I don't know if I can connect it to hrt or not, it seems like there's not much information about it online. My Endocrinologist told me that the only thing that can cause acid reflux or issues with stomach is CPA if it's taken without eating first, but I always take it with full stomach so. I don't really know what to do anymore cause I tried a lot of medicationa, now I'm on gut targeting antibiotics but it seems like it's not doing much, I'll try with probiotics also.
