I am suffering with bloody piles for the last 30 years.should i get it opetated upon or take up medication ? what are the foods to be avoided?

Bleeding piles: With bleeding for long time, recommend having it looked at by your primary care doc.

Diet and fluids: In general eating a high fiber diet and more importantly, drinking 80-100 ounces of non caffeinated, non alcoholic fluid per day, more if excercising vigorously, should be adequate enough to keep your hemorrhoids quiet. If in doubt or not successful instituting above, get them checked by a colorectal surgeon.
