@wa34937 also the right probiotics could help. There is also a product line called heathers with IBS type products. Importantly Heather has a type of soluble fiber that can smooth out constipation And diarrhea and it is different than the garden variety insoluble fiber. It’s called heather‘S tummy fiber. Last, check or Dr. Fors book called “why we hurt and how we heal”. He talks about chronic pain but also gut health a lot. He suggests certain supplements and diet suggestions. Those might help. Good luck.
