Please suggest what food can be eaten while treating anal fissure with hematoma?

Low residue: While diet doesn't directly affect anal fissure, a low residue diet can help reduce the amount of stool produced, which is good because bowel movements are usually painful until the fissure heals. Hope this helps!

HYDRATE: It's top priority to keep yourself well hydrated. You should be consuming some degree of fibre as well. And, personally, i'd avoid anything particularly spicy which could irritate the anoderm. Good luck.
