Talk to Gastroenterologist on Accute GERD, Constipation And Too Much Facial Oil.

I have been facing this problem for four years now. I have severe GERD and constipation I am already taking PPis and zantac but this problem doesn't seem to go away. I have bitter taste in mouth when i wake up. I feel immense heat in my body. i always feel thirsty even in the coldest days of winter. i always have too much oil on my face but i feel very dry inside. I really want this problem to be diagnosed instead of taking pills blindly every day.
