causes of hemorrhoids

A common cause of hemorrhoids is simply the standing position, in which all the blood above the rectum exerts pressure on the rectal and anal areas. Other conditions which contribute to hemorrhoids are: poor bowel habits, constipation, diarrhea, pregnancy, obesity, and especially frequent straining when having a bowel movement. However, some patients will have none of these conditions and still develop hemorrhoids. Humans are prone to hemorrhoids because erect posture puts a lot of pressure on the veins in the anal region. Heredity has also been considered a factor, since hemorrhoids tend to run in families. Chronic constipation is considered a major cause of hemorrhoids.

This is because constipated individuals tend to consistently strain to evacuate their bowels, increasing pressure in the rectum. Disturbance from frequent bowel movements associated with diarrhea can also be a cause. Additionally, frequent use of laxative may result in diarrhea, and increase your likelihood of getting hemorrhoids. Increased abdominal pressure can often encourage hemorrhoids.

People who exert themselves strenuously at work or who stand for long periods of time are most often afflicted. Pregnancy is a common cause of hemorrhoids among young women. They are most common in the final trimester because there is increased pressure from the enlarged uterus. Constipation, also common during pregnancy, adds to the problem. Other factors that encourage hemorrhoids include lack of physical activity and a low daily intake of fluids.
