Hemorrhoids can be divided into three types: external, internal and mixed
External hemorrhoids are divided into: thrombotic external hemorrhoids, varicose external hemorrhoids, inflammatory external hemorrhoids, connective tissue external hemorrhoids
Staging of internal hemorrhoids:
Stage I: There is a vermilion varicose bulge above the tooth line without mucosal changes. The hemorrhoids are sessile, soft and easy to bleed. This stage is also called first-degree internal hemorrhoids.
Stage II: The hemorrhoids are enlarged, have pedicles, purple-red color, rough and thickened mucous membranes, prolapse outside the anus during defecation, and contraction of the anal sphincter after defecation, and the hemorrhoids will retract into the anus. This stage is equivalent to second-degree hemorrhoids.
Stage III: The hemorrhoids protrude out of the anus during defecation, and there is mucosal erosion. After defecation, the hemorrhoids cannot be retracted into the anus. Hand help is needed to push the hemorrhoids back. This stage is equivalent to third-degree hemorrhoids.
Stage IV: Hemorrhoids not only prolapse outside the anus during defecation, but work, exertion, coughing, sneezing, etc. can cause prolapse, and mix with the varicose veins on the anal skin, which is equal to mixed hemorrhoids.
