I highly recommend seeking out a functional medicine doctor since you all have gone through the medical system that isn’t giving you answers or helping. I had digestive issues and had 3 endoscopies over 7 years and always put on a prescription that helped. But once I was off them, symptoms returned. At my last endoscopy, the GI doctor told me to never take the med I was on again. I had been put in a Proton Pump Inhibitor or PPI and the cells in my gut were hypertrophic (very enlarged).
I turned to functional medicine that treats the cause. I was tested for SIBO, SIFO, yeast, mold and parasites. I had everything except parasites. You can search for a functional medicine doctor by city and state at ifm.org. Seek one out that specializes in digestive disorders and preferably also has a nutritionist on staff. I’ve been with mine for two years and I’m recovering well, feeling normal. Stress also needs to be addressed but not with antidepressants. Seek out a good mediation app that helps you with breath work and teaches how to regulate yourself when you start feeling stressed. Stress is a huge gut disruptor. If you haven’t read anything about the brain and gut connection, Google it and learn about how our thoughts/stress affect the gut.
I wish you all the best in your journey and hope you find relief.
