1. Blood in the stool: In the early stage, it is more attached to the surface of the stool or blood on the hand paper. Frequent episodes but small amount. With the aggravation of symptoms. When the internal hemorrhoid comes out during defecation, it can be shown as dripping or shooting blood, and the number of episodes decreases, but the amount of blood increases, which can reach tens of milliliters at a time. Repeated heavy bleeding can cause hemorrhagic anemia. The blood in the stool of hemorrhoids is painless, bright red, and can be with blood, dripping blood and ejection. 2.Prolapse: Due to the increase in the size of the hemorrhoid nucleus, the hemorrhoid nucleus separates from the muscle layer and prolapses out of the anus due to fecal impact and extrusion during defecation. Initially, it only comes out during defecation and can be reset by itself after defecation. When the symptoms are aggravated, the nucleus cannot be returned by itself after prolapse and needs to be rested by hand or bed rest. In the later stage, in addition to prolapse during defecation, it can be prolapsed when straining, walking, coughing, sneezing, squatting or when you are not concentrating. The nucleus of the hemorrhoid is prolapsed, the mucosa is easily damaged by infection and inflammation, edema and pain, and if not reset in time, it can become embedded, making it difficult to reset. 3.Pain: Internal hemorrhoids alone are painless, but if they are embedded or infected, ulcerated, or thrombosed, they can cause severe pain. When the internal hemorrhoid is embedded, the patient has unbearable anal pain, restlessness, obstruction of defecation and vectoring, and sometimes the reflex causes urinary retention. 4.Anal swelling: All stages of internal hemorrhoids can have different degrees of anal swelling, with the late stage being heavier. In the middle and late stages, the feeling of incomplete defecation can appear. The cause of anal swelling may be the stimulation of the rectal mucosa by the enlarged hemorrhoid nucleus, or the inflammation of the mucosa. 5.Mucus overflow, anal dampness, itching: Internal hemorrhoids prolapse, mucous membrane inflammation and erosion, exudate increase, late stage internal hemorrhoids often have secretions due to anal sphincter relaxation, intestinal fluid overflow, contamination of underwear, patients feel anal dampness. Due to the stimulation of intestinal fluid, the anal skin becomes hypertrophic and mossy, and itching is unbearable, especially at night.
