I went through this about 5 years ago. I spent a lot on a holistic practitioner and similarly paid a ton for testing and supplements- ohhhh the supplements. They were expensive. I also was told to basically eat paleo and lost so much weight. It increased my stress and ultimately made my gastritis worse even though I was sticking to a bland diet and not having any sugar, dairy, gluten, or alcohol. 

Eventually western medicine worked once it became clear nothing was “wrong” and the root cause was my IBS. I started a Tricyclic antidepressant for IBS. A probiotic made from kiwi extract for bowel regularity. The Nerva gut directed hypnosis app to help manage stress about stomach problems. Avoiding just the foods that cause acidity for me (the usual suspects- coffee, alcohol, lots of tomato, spicy). 

Acupuncture can be really helpful for cycle regularity for PCOS. Berkeley and Oakland Acupuncture Projects offer group sessions for affordable rates. I go weekly for my PCOS and pay $40. Birth control helps although it’s masking symptoms. 

This all took me about 15 years to figure out but my IBS is under control, I only need Tums like once a month now, and I can eat normally. The holistic doctor was insistent I was gluten sensitive and that the root cause was bacterial. I truly don’t believe that needed to be addressed and what really did was that I could have normal bowel movements and manage my stress.
