External piles, also known as hemorrhoids, are swollen blood vessels located around the anus or in the lower rectum. They can cause discomfort, itching, and bleeding during bowel movements. External piles are often caused by increased pressure in the lower rectal area, which can result from factors like pregnancy, obesity, or straining during constipation. Treatment for external piles typically includes lifestyle changes, such as increasing fiber intake and staying hydrated. Over-the-counter creams and ointments may also provide relief from symptoms. In more severe cases, medical procedures like rubber band ligation or surgery may be necessary to remove the piles.
