Hemorrhoids, also known as piles, are a common condition in which the veins in the rectum or anus swell, sometimes painfully. You often see these dilated varicose veins during and after pregnancy or in other situations that put pressure on or around the anus. They're most common in adults of 45-65 years, though men are more likely to get them than women.  Hemorrhoids can go away on their own — commonly during pregnancy— but medical attention is necessary if they persist. Simple self-care methods will help you relieve the itching and discomfort in the meantime.
