The main cause of anal bleeding during each bowel movement is the formation of hemorrhoids, especially internal hemorrhoids located above the dentate line, in addition to mixed hemorrhoids, which are often triggered by aggravation of symptoms after overeating or constipation, and should also pay attention to perianal hygiene and reasonable adjustment of diet structure. If you have underlying lung disease, such as chronic obstructive pulmonary disease, recurrent cough, coughing phlegm, and benign prostatic hyperplasia in elderly male patients, it can lead to increased abdominal pressure, which can also trigger the formation and aggravation of hemorrhoids. You should actively treat the underlying disease, develop good habits of regular bowel movements, and if your condition allows, you can use a warm salt water sitz bath every day before bedtime to be able to reduce the symptoms. You can also use topical hemorrhoid cream or hemorrhoid suppositories, which can also alleviate the patient’s condition.
