As either external or internal swollen veins situated in the lower rectum or around the anus, hemorrhoids are far from pleasant and not at all uncommon. Increased age, pregnancy, obesity, and straining from bowel movements are usual causes of hemorrhoids. However, more often than not, the cause for their occurrence is unknown. By the age of 50, at least half of all adults will experience their unpleasant effects.Also, commonly known as piles, hemorrhoids are similar in nature to varicose veins and can occur both inside the rectum (internal hemorrhoids) or under the skin surrounding the anus (external hemorrhoids). They are often uncomfortable and painful, and accompanied by significant itching. Sometimes, bleeding can also occur if a clot develops within them, in which case lancing and draining by a physician would be necessary.
