The causes of haemorrhoid bleeding are mainly related to the increased pressure of local congestion in the anal nucleus, when patients have an acute attack of haemorrhoid disease, there is a local breakdown of the mucous membrane of the nucleus and rupture of small blood vessels, resulting in bleeding in the stool. In addition, many patients with haemorrhoids have chronic constipation, long bowel movements and other bad habits, which are also the main reasons for aggravating haemorrhoid bleeding.
