Hemorrhoids are divided into internal, external and mixed hemorrhoids. For separate external hemorrhoids, no anal discomfort, itching, pain and other clinical symptoms, can be without treatment. Internal hemorrhoids are divided into four phases: Phase I: no obvious self-conscious symptoms, only when defecating with blood, dripping blood or spraying blood phenomenon. The hemorrhoids do not come out of the anus. Stage 2: intermittent blood, dripping or spraying during fecal discharge, with moderate bleeding. The hemorrhoidal mass may prolapse out of the anus during defecation, and can be incorporated back into the anus by itself after defecation. Stage 3: internal hemorrhoids prolapse during defecation, or after exertion, walking too long, coughing. Internal hemorrhoids can’t be returned to the anus by themselves, and must be put into the anus by hand, or can be returned to the anus after bed rest, and the bleeding is small. The fourth stage: hemorrhoids in the anus for a long time, can not return to the anus, or back to the anus and then immediately prolapse. Hemorrhoid development to the latter three stages more into the mixed hemorrhoids, because the prolapse of hemorrhoidal block is larger, has involved the hemorrhoidal internal and external venous plexus and the surface of the rectal mucosa and the anal canal skin covered, therefore, the mixed hemorrhoids is the hemorrhoids continue to aggravate the consequences of the hemorrhoids. The clinical manifestations of hemorrhoids: there are mainly the following aspects: 1, blood in the stool: mostly bright red, can be a drip and can also be jet bleeding. Dry feces, drinking alcohol, fatigue, over-eating spicy stimulating food is often the cause of bleeding. 2, internal hemorrhoid mass protrudes from the anus. 3, mucus spillage: rectal mucosa long-term stimulation by hemorrhoidal nuclei, producing inflammatory exudation, so that the secretion increases. The outflow makes the anal skin often stimulated and eczema and itching symptoms occur. 4, pain: internal hemorrhoids are mostly painless, such as accompanied by anal fissure, internal hemorrhoids embedded, causing edema, thrombosis, erosion and necrosis when there is severe pain.
