my gf has IBS or mayb something related. problem is, after meals, she will feel bloated and belly will swell abit and bowel movement only comes mayb after 1 or 2 days. all the while she will feel gassy in the belly. She has tried fibre, and even taken supplements to enhance the liver after suggestions that low bile production may influence irregular bowel movements.

Mayb will ask her to try probiotics?
