Internal hemorrhoids are mainly in the area above the dentate line of the rectal mucosa of the anal canal, about 3 cm from the anal opening. In the early stage of internal hemorrhoids, internal hemorrhoids will not prolapse, mainly causing patients to have intermittent painless blood in the stool, which can be detected in this area through anal finger examination or by doing anoscopy. However, with the aggravation of internal hemorrhoids, the internal hemorrhoids may prolapse at the anal opening, there will be different degrees of downward movement, and many patients will be able to see the internal hemorrhoids at the anal opening, and in serious cases, internal hemorrhoids will become embedded and edematous, resulting in severe anal pain. For this condition internal hemorrhoids need to be treated with surgery as soon as possible to avoid infection and necrosis of the internal hemorrhoids. Patients should usually develop good bowel habits, keep their bowels open, do more anal lifting exercises, and avoid prolonged sitting and squatting to avoid aggravation of internal hemorrhoids.
