Patients with hemorrhoids should not stand for long periods of time. This is because the upright position affects the venous blood flow back to the rectum and anal canal, and can also lead to increased symptoms in patients with pre-existing hemorrhoid disease. Patients may experience significant anal swelling and even pain and itching. Because the cause of hemorrhoids is related to poor local blood circulation, it is mainly the increased abdominal pressure that causes the dilatation of the blood vessels in the rectum and the submucosa of the anal canal, which eventually form venous sinuses. The abdominal pressure in the upright position is three times or more than the pressure in the lying position. So for patients with hemorrhoids can not stand for a long time. However, you can do sports and exercise to improve the peristaltic function of the intestines, which can relieve hemorrhoids to some extent. Patients with hemorrhoids should also perform appropriate exercises to contract the anal levator muscle in order to help the recovery of the disease.
