While the exact cause of hemorrhoids remains unknown, a number of factors which increase pressure in the abdomen are believed to be involved. Often, no specific treatment is needed. If not thrombosed , external hemorrhoids may cause few problems. Internal hemorrhoids usually present with painless, bright red rectal bleeding during or following a bowel movement. The exact cause of symptomatic hemorrhoids is unknown.
Piles (haemorrhoids) - NHS
Hemorrhoids, also called piles, happen when clusters of veins in your rectum or anus get swollen or dilated. When these veins swell, blood pools and causes the veins to expand outward into the membranes around your rectal and anal tissue. This can become uncomfortable or painful. But when they expand, they can look like red or discolored bumps or lumps. In fact, less than 5 percent of people who get hemorrhoids have symptoms. Even less need treatment. At least three of every four adults will get them at one point in their life.
Hemorrhoids are not an easy disease. They are extremely painful and can lead up to other diseases. Hemorrhoids are embarrassing and can cause a lot of discomfort to a person suffering from it. The symptoms of hemorrhoids are visible as it is followed by blood loss, weakness, difficulty in passing stool, fatigue and bloating.
