Hemorrhoids are divided into internal and external hemorrhoids, hemorrhoids are related to constipation, and the anal protrusion caused by hemorrhoids can be treated surgically. The main symptoms of hemorrhoids are blood in the stool and prolapse, and you will feel discomfort at the anus. In the early stages of hemorrhoids, you can also choose medication. Hemorrhoids are prone to recurring attacks, and you must pay attention to your eating habits after healing, eating less indigestible food and less spicy and stimulating food. Keep your bowels open, develop good bowel habits, and do physical exercise regularly, not only to help digestion, but also to prevent hemorrhoids from recurring.
