The occurrence of this type of blood in the stool indicates that the amount of bleeding is relatively large. Below is a detailed introduction to the causes of blood in stool. Friends who have this problem can come and learn about it.

1. Bleeding in stool is caused by the following five reasons:

1. Anal fissure:

Anal mucosal injury:

The most common cause of bloody stools in children is not hemorrhoids but anal fissures. Children with anal fissures will experience severe pain after defecation, which often causes them to cry and become restless. The main cause of anal fissures in adults is chronic constipation. During defecation, blood can be seen on the surface of the stool or on toilet paper. The color is bright red, and sometimes blood can be seen. Patients often have severe pain during defecation or persistent pain after defecation.

Anal abscess or foreign body in the anus:

When abscesses around the anus rupture or foreign objects such as fish bones get stuck in the anus, causing infection, there may be pain and blood in the stool. Surgical treatment is required.

2. Hemorrhoids:

Hemorrhoids are the most common cause of blood in the stool, but it cannot be said that all blood in the stool is caused by hemorrhoids. Many other diseases may also cause hemorrhoids. The blood in the stool caused by hemorrhoids is not mixed with the feces, the blood is bright red, and there may be bleeding during defecation or dripping blood after defecation. However, patients cannot judge that their bloody stools are caused by hemorrhoids based solely on these symptoms. They need to go to a regular anorectal hospital for a confirmed diagnosis.

Internal hemorrhoids:

The characteristic is that the blood in the stool is bright red and appears in drips or spurts. Bleeding during or after defecation may be caused by hard stools abrading the mucosa, or by excessive force during defecation, which increases the pressure in the blood vessels and causes varicose veins to rupture and cause bleeding.

External hemorrhoid inflammation:

He felt a swelling in his anus, which was painful and swollen, and there was a small amount of blood when he wiped his hand after defecation. Conservative treatment is the same as before, and surgical treatment is generally required.

3. Ulcerative colitis:

Patients with ulcerative colitis have abdominal pain and diarrhea in addition to blood in the stool. Mild cases may defecate 7-8 times a day, while severe cases may defecate more than 10 times a day. The blood is dark red and is often mixed with unformed stools, and is also mixed with mucus, pus and blood.

4. Colorectal cancer:

This is the most serious disease that causes blood in the stool. In the early stages of colorectal cancer, patients may find a small amount of bright red blood on the surface of the stool, which can easily be mistaken for hemorrhoids. As the disease progresses, blood in the stool will gradually worsen, and there will also be changes in bowel habits, thinning of the stool, intestinal obstruction, etc. In addition, patients may also experience systemic symptoms such as general fatigue and rapid weight loss.

5. Colon polyps:

It is a common benign tumor in the intestine, but it may become malignant if not treated in time. The patient's bloody stool is usually characterized by intermittent bleeding, bright red in color, but not in large amounts and not mixed with stool. Some patients will have a fleshy lump protruding from the anus during bowel movements, which will retract into the rectum on its own after defecation.
