These are also called piles. These are swollen veins that are present around the anus. Irregular bowel habits, including constipation and diarrhea, low fiber diet, less intake of water, genetics and lack of exercise are some of the causes of the hemorrhoids. Mostly they cause a mild discomfort but these can become painful when they are strangulated, bulged out of the anus or the veins are ruptured and thus develop the blood clot.
