Epidemiology and Demographics
Hemorrhoids are common. In the USA, the prevalence is about 4.4%.[1][2] It is estimated that approximately one half of all Americans have had this condition by the age of 50, and that 50% to 85% of the world's population will be affected by hemorrhoids at some time in their life. However, only a small number seek medical treatment. Annually, only about 500,000 in the U.S. are medically treated for massive hemorrhage, with 10 to 20% of them requiring surgeries.
