Clinically, there are three common types: hemorrhoids, anal fissure and rectal cancer.
Their respective characteristics of bloody stool:
Hemorrhoids and hematochezia are mostly painless, often intermittent post fecal bleeding. Blood is often dripped into the urinal and does not mix with feces. Severe patients will spray bleeding, which may be caused by rubbing the mucous membrane too hard during defecation. Generally speaking, bleeding after defecation will stop by itself. Constipation, dry and hard stool, drinking and eating * * food are the causes of stool bleeding. How to treat hemorrhoids and hematochezia requires different treatment measures according to their symptoms.
Anal fissure and bloody stool. In addition to bloody stool, there are symptoms of post stool pain. Adult anal fissure is mostly caused by long-term constipation. Most patients bleed during defecation, mostly blood, and the amount of bleeding is not much. Sometimes it is found that the toilet paper is stained with blood, and then the blood is attached to the fecal surface. This is mainly caused by feces rubbing small blood vessels on the ulcer surface. In addition to bloody stool, patients also have severe pain. Generally, the pain will reduce or disappear briefly after a few minutes, which is called the pain interval. After that, patients will have severe pain due to continuous muscle spasm, and the pain time will even last for several hours to more than ten hours. The special process of this pain is called "anal fissure pain cycle".
Rectal cancer: hematochezia caused by rectal cancer mainly occurs among people in the coming year. Its symptoms are mainly pus blood, mucous membrane or putrid secretions mixed in feces. At this time, we should carefully check the causes of bloody stool to avoid missing the best treatment opportunity for rectal cancer.
