What Are the Causes of Internal Hemorrhoids?
Hemorrhoids are one of the most common medical ailments known. According to The American College of Gastroenterology, nearly half of all Americans will develop them by the age of 50. Two types of hemorrhoids occur, external and internal. External hemorrhoids appear as swollen or dilated blood vessels in and about the anus and lower rectum. Internal hemorrhoids develop inside the rectum and above the anal opening. Both types of hemorrhoids develop from increased pressure in the veins of the anus.
