Both internal and external hemorrhoids may exhibit symptoms of hemorrhoidal bleeding, making it unclear whether the bleeding originates from internal or external hemorrhoids. Patients are advised to seek medical attention to identify the cause and receive treatment. Internal hemorrhoids form due to pathological changes in the supporting structures of the anal cushion, venous plexuses, and arteriovenous anastomoses, leading to congestion, hyperplasia, enlargement, and displacement of the anal cushion. Internal hemorrhoids grow above the dentate line of the anus and have abundant blood supply. As they continue to grow, they can cause脆化 (brittleness) of the rectal blood vessel walls, making them prone to bleeding when stimulated by bowel movements. Early-stage internal hemorrhoids may cause intermittent bleeding, which can sometimes turn into jet-like bleeding in severe cases. External hemorrhoids are formed by pathological dilation of subcutaneous venous plexuses or hyperplasia of connective tissue on the distal side of the dentate line, with the primary symptoms being pain and itchiness in the anal area. If the size of external hemorrhoids continues to increase, they may rupture and bleed during forceful bowel movements. Therefore, it is impossible to determine whether the bleeding is from internal or external hemorrhoids solely based on the symptom. It is necessary to promptly undergo rectal digital examination and anoscopy at a formal hospital for diagnosis through various examination methods. If diagnosed with hemorrhoids, patients can use medications such as Compound Carrageenan Suppositories and Musk Hemorrhoid Suppositories under the guidance of a doctor to improve symptoms. Warm sitz baths can also be taken to accelerate local blood circulation. In daily life, it is important to develop good bowel habits, drink plenty of water, consume vegetables and fruits rich in vitamins and fiber, and avoid prolonged sitting and spicy or irritating foods.
