Internal hemorrhoids tend to appear within the anal tooth line and the upper part is located within the rectum of the anal canal. As the saying goes, nine out of ten people have hemorrhoids, so there are still more people who have hemorrhoids, mainly due to poor dietary habits and bad bowel habits. In the diet often eat spicy, stimulating, hot and dry food, often like to eat fatty, sweet and greasy food, easily lead to damp heat stagnation in the anorectum, which leads to blood in the stool. As a result of frequent dry and hard stools, it is easy to cause the anal cushion to move down, which can lead to the formation of venous masses. Most patients with internal hemorrhoids do not affect their normal life, and patients with milder symptoms can choose conservative medications for treatment. If the symptoms are not relieved by conservative therapy or if the hemorrhoids bleed more, they can be treated by laser surgery, anastomosis hemorrhoidectomy and hemorrhoid ligation therapy in more severe cases.
