I am no doctor. But in my experience, healthy eating with much fibers helps with that. Anything with much sugar or much carbs like soft drinks or white bread make it worse. Its a really compex topic, so if you have problems with it go either to a doctor or google and Experiment by yourself, but watch out for potential scams like food supplements.
Good luck
They are way less undercover around here. Theres a helicopter that spies on everyone 2-3 times a month. No infos on flightradar, no infos directly sent from it. We are all dead soon!
