Stool blood is serious

Blood in the stool is also known as hematochezia, and the severity of blood in the stool depends on the cause of the blood. However, there are many reasons for bloody stools, such as getting angry, gastrointestinal bleeding, hemorrhoids, and some blood diseases. After discovering bloody stools, first check whether there are other discomforts in the body. If there are no other discomforts, take medicine to reduce internal heat, eat a light diet, avoid spicy and irritating foods, and do not sit for a long time to reduce abdominal pressure. This article introduces the causes of blood in the stool and the diseases that manifest as blood in the stool.

1. Causes of blood in stool

1. Small intestinal bleeding, such as intestinal tuberculosis, localized enteritis, acute hemorrhagic necrotizing enteritis, intussusception, small intestinal tumors, etc.

2. Colon bleeding, such as dysentery, ulcerative colitis, regional enteritis, colon cancer, etc.

3. Rectal bleeding, such as rectal damage, hemorrhoids, anal fissure, rectal cancer, etc.

4. Other diseases, such as various blood diseases, hemorrhagic fever, typhoid and paratyphoid, hookworm disease, vitamin deficiency, etc.

2. Common Diseases

1. Anal diseases

1. Anal fissure: Anal fissure will cause blood in the stool due to the friction of feces during defecation. The amount of blood in the stool is not much, and it is generally bright red in color and not mixed with feces. It will also be accompanied by severe pain, which will last for a long time after defecation.

2. Hemorrhoids: In the early stages of hemorrhoids, there is usually painless blood in the stool. The blood in the stool is bright red, not in large amounts, and is mixed with feces. It usually appears on toilet paper after defecation and is distributed in droplets. It is caused by repeated friction of feces. In the middle and late stages of hemorrhoids, tumors will prolapse, hemorrhoids will become edematous and inflamed, and severe pain will occur.

3. Anal polyps: The friction of feces during defecation causes damage to the epidermal tissue of the polyps. It is usually painless and bloody in the stool. The amount of blood in the stool is not large and is bright red in color. It is not mixed with feces. At the same time, the polyps may fall out.

2. Rectal diseases

There is no sign of bleeding in the early stages of rectal cancer, only a slight feeling of heaviness. If allowed to develop, in the middle and late stages, there will be an increase in the frequency of bowel movements, and bleeding during bowel movements. The amount of bleeding is not much, and the color is dark red. In the late stages, the amount of blood in the stool will increase, accompanied by mucus exudation, emitting a foul odor.

3. Digestive tract diseases

Due to problems in life, such as diet, defecation, etc., frequently eating spicy and other irritating foods can easily irritate the digestive tract and cause bleeding in the digestive tract. Bleeding from digestive tract diseases is usually tarry and dark brown in color and the amount of bleeding is not much.

3. Harm of blood in stool

1. Blood in the stool may indicate the occurrence of a variety of anorectal diseases. Blood in the stool is a common symptom, and its appearance often indicates the occurrence of some anorectal diseases. Among the many anorectal diseases, hemorrhoids, anal fissures, rectal polyps, colon polyps, ulcerative colitis and even rectal cancer can cause blood in the stool. Blood in the stool often becomes a "disguise" for serious diseases such as rectal cancer, causing patients to relax their vigilance and ultimately suffer from the harm of the disease.

2. Long-term bloody stools can cause iron deficiency anemia. It is reported that long-term bloody stools can easily cause the patient to lose a large amount of iron in the body, causing iron deficiency anemia. Iron deficiency anemia generally develops slowly.
