Internal hemorrhoids are usually divided into four stages according to the degree of bleeding, the size of the hemorrhoids, the prolapse of the hemorrhoids and the length of the disease. The staging standard is mainly determined according to whether the hemorrhoids are prolapsed and whether they can be taken back by themselves after prolapse, or if they need assistance.
Stage I Hemorrhoids are small, soft, and bright red. They often bleed due to the hemorrhoids being rubbed by the stool; the blood may be like arrows or dripping, no pain, and no prolapse. Blood in the stool is its characteristic.
Stage Ⅱ Hemorrhoids are large, soft in texture, bright red or bluish in color; they can protrude outside the anus during defecation, and will be absorbed by themselves after defecation, with more or less blood in the stool.
Stage III hemorrhoids are larger and slightly off-white on the surface (due to repeated prolapse of the hemorrhoids, the mucosal surface shows fibrotic changes, also called fibrous internal hemorrhoids); the hemorrhoids prolapse outside the anus during defecation, even when walking, coughing, sneezing, or standing. Cannot take it back on its own. It can only be taken back after being pushed by hand or lying flat or hot compress. There is not much blood in the stool or bleeding.
Stage IV: Hemorrhoids prolapse outside the anus and cannot be returned to the anus. The hemorrhoids have obvious edema, accompanied by severe pain, or accompanied by thrombosis.
