DEAR DOCTOR K: I've suffered with bleeding hemorrhoids for many years and lifestyle changes haven't helped. My doctor suggested surgery. Is this risky?
DEAR READER: Hemorrhoids are swollen veins in the anus. Many people have both internal and external hemorrhoids. Internal hemorrhoids are located inside the anus, but can sometimes push out through the opening of the anus. External hemorrhoids are located at the rim of the anus. Both types can cause bleeding, itching and discomfort.
