Hemorrhoids are caused by poor diet, lack of exercise, being overweight and constipation. Hemorrhoids also occur in pregnant women and in the elderly where strain on the rectum and anus increases beyond the normal threshold resulting in swollen clumps of veins. These blood vessels form soft lumps within the rectum causing pain, itching and irritation. Sometimes these clusters of veins can protrude out the anus causing even greater discomfort. Hemorrhoids can easily be prevented with a healthy lifestyle, getting enough exercise, eating enough fresh fruit and vegetables and avoiding sitting too long. Pregnant women often suffer from constipation due to increased pressure on the bowel from the uterus. By drinking more water, avoiding dairy and taking stool softeners, pregnant women may prevent the constipation and thus avoid the consequent straining, which leads to hemorrhoids The elderly can also prevent hemorrhoids by following a healthy diet and drinking plenty of fluids, which alleviates constipation. The best treatment for hemorrhoids is to prevent them from occurring and this is easily done by maintaining a healthy lifestyle.
