I am suffering from piles after delivery. it's been 3 months since the delivery date. how this can be cured?

Minimal treatment: Hemorrhoids after childbirth are not unusual. Rarely do they require surgery. The best thing is to avoid straining by taking a stool bulk-former from the corner drug store. The hemorroids will shrink on their own most of the time the farther you get from childbirth. If they come out and do not go back on their own, or if there is significant pain, see a proctologist(colon-rectal surgeon).

Psyllium Fiber: If you want to only care for this without any surgical intervention, then psyllium fiber or an equivalent is likely the best treatment for long term. Make sure you purchase unflavored psyllium. Start with a teaspoon a night mixed in 16 oz of water every night. Unless they are stuck out and causing significant pain or itching, surgery can usually be avoided.
