IBD, IBS and other health issues

I wanted to check if anyone in this community has had been facing gut issues like the ones mentioned? If yes how are you guys coping with it. Most of the folks here talk about money, jobs, layoffs etc but I guess health is underrated.

I have been suffering from IBS since 7-8 years and has it under control for the past 2 years. Suddenly for severe diarrhoea ( 8-10 times a day). Took usual meds from local doctor for 11 days. Things lined better but again after 4 days diarrhoea started. Since functional diseases don't have a cute, do some of you have it? How do you cope with it. What to avoid and what to do or consume more?

I will start with mine:

1. Avoid stress
2. Avoid Outside oily and spicy food
3. Prefer coconut water, buttermilk etc
4. Avoid lactose
5. Avoid some nuts
6. Have fermented items more

What ur take and how do you cope? What helped and what didn't? Who are some good doctors who helped and changed ur life (For me it was Akash Shukla in Mumbai)?
