Hemorrhoids are also a common symptom in patients who exhibit blood in their bowel movements. Hemorrhoids are caused by local vasodilatation with varicose vein masses forming, and in severe cases blood pools within the vein masses, forming thrombotic emboli, which can cause significant painful symptoms and bleeding due to damage to the hemorrhoid mucosa during defecation. In the case of hemorrhoid vascular damage, it can also manifest itself as a clot or heavy bleeding, which requires prompt surgical treatment of choice, ligation of the hemorrhoid nucleus or removal of the hemorrhoid. After surgery, you also need to change the medication regularly, and you should do physical exercise, the exercise of contraction of the anal raphe, which can improve the venous blood return around the anus and also relieve the symptoms of discomfort.
