Causes of blood in the stool Almost all gastrointestinal bleeding can cause blood in the stool, but the common causes of blood in the stool are:
(1) Anal diseases caused by blood in the stool:
①Blood red and no pain are more common in internal hemorrhoids. Stage I hemorrhoids are characterized by blood. They often bleed due to the hemorrhoids being rubbed by the stool. The blood may be dripped or ejected, or only blood on the toilet paper; Stage II hemorrhoids have little or no bleeding in the stool and often protrude outside the anus.
② Anal fissure blood in the stool is often accompanied by anal pain and typical periodic pain after stool.

②The main manifestations of rectal cancer are increased stool frequency, thin stools, mucus and blood, accompanied by tenesmus or incomplete defecation, blood in the stool is bright red or dark red in the early stage, and the amount is not large. There is often foul-smelling mucus in late stool, and weight Mitigation should be highly valued.
③ Radiation proctitis may also have blood in the stool, but there should be a history of radiation therapy.
(3) Colon diseases caused by blood in the stool:
① Colon polyps.
②Colon cancer: It is common in left colon cancer. Most patients have intractable constipation, and occasionally the number of stools may increase. When the cancer ruptures, it may stain the outside of the stool with blood or mucus, and even discharge pus.

Identify the color of blood in the stool
The color of blood in the stool depends on the location and speed of the gastrointestinal bleeding. Upper gastrointestinal bleeding and small intestinal bleeding are mostly dark red or black stools. However, if the bleeding rate is faster, the amount of bleeding is large, and the bowel movement increases, the blood can appear dark red or bright red. When bleeding from the colon and rectum, because the blood stays in the intestine for a short time, bright red or brighter red blood is often discharged.
Although the above screening method is simple and effective, many people cannot distinguish the color of blood in the stool. Therefore, we suggest that when blood in the stool is first discovered, we must pay attention to it. Go to a regular specialist hospital for routine stool examination and anoscopy to confirm the condition and treat symptomatically. Do not take medicine or ignore it and let it develop. The continued development of hemorrhoids after complications will cause increased bleeding, unbearable pain and affect work and life; and once the disease involves other human organ systems, if the blood in the stool is ignored, many diseases will lose the best time for treatment.
Of course, blood in the stool may be the most common type of hemorrhoids. About 90% of hemorrhoid patients have blood in the stool, especially after the winter season is the high incidence period of hemorrhoids. If you are a hemorrhoid patient, you should treat it early. Many patients have heard that hemorrhoids must be treated with surgery and they have been delayed. The delay that can be solved by medical treatment has become surgical treatment, and the treatment that can be cured by minimally invasive surgery has been delayed and complicated surgery. We also need to explain that hemorrhoid surgery is not as scary as everyone thinks. The Johnson & Johnson PPH surgery and HCPT high-frequency capacitance field treatment that have recently been used in clinical medicine are all outpatient treatment methods, which can basically achieve painless and rapid healing. Follow the rule and go without delaying normal work and study. Therefore, it is necessary to remind the majority of patients to check as soon as possible to determine the cause of blood in the stool, and patients with hemorrhoids and anorectal diseases must be checked and treated early to avoid aggravation of the disease and bring greater harm to their own health.
