One of my school friend met me in US and he told me he is suffering from IBS. I already gone through IBS and had completely cured. So I advised him to follow few simple instructions. He started following instructions and he told me his IBS is getting cured and feeling a lot better. So here are those simple instructions that I told to my friend.
1) Avoid eating Cheese as they sticks to your intestine and cause conjunction.
2) Avoid eating frozen food(meat, fish). Freshly cook the food and eat while it is hot.
3) Eat 2-3 tbsp of sweet Curd after each meal.
thats it. so simple.
