For the past 3 or 4 months, I have been having heartburn maybe once a month or so which lasts about 3 days then it would go away. I also noticed that every time I have heartburn, it accompanies watery stools/diarrhea. I never had this problem before. I just realized that maybe the acid reflux is caused by stress which began the same time during a difficult period in my life. I am just not sure if these are two separate issues and just coincidentally occur at the same time or if one problem causes the other one to occur. There are no other symptoms besides reflux symptoms (feeling of wanting to vomit, bitter taste in the mouth, worse heartburn when lying down). No bloody stools, no abdominal pain, watery stools (very watery like peeing) up to 3X/day. I would appreciate any advice.
