Blood in stool

Fresh blood in the stool is commonly known as bloody stool. This symptom is very common in many anorectal diseases and is a common feature of many anorectal diseases. A single symptom cannot accurately determine the cause of the disease. It requires a comprehensive judgment based on other physical symptoms. We can first understand the possible causes. So, what are the reasons for blood in stool? Let’s take a look below.

(I) Anal diseases 1. Anal fissure: Anal fissures can cause blood in the stool due to friction with feces during defecation. The amount of blood in the stool is not much and is generally bright red in color. It does not mix with feces and is accompanied by severe pain that lasts 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.

If left unchecked, 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 increases and is accompanied by mucus exudation, emitting a foul odor. (III) Digestive tract diseases: Due to problems in life, such as diet, defecation, etc., eating spicy and other irritating foods frequently 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.

The harms of blood in stool 1. Blood in stool may indicate the occurrence of various anorectal diseases. Blood in stool is a common symptom, and its occurrence 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. In the early stages, there may be no symptoms or mild symptoms. In severe anemia, patients may experience pale complexion, fatigue, loss of appetite, palpitations, rapid heart rate, shortness of breath and edema after physical activity. Some patients may even experience neurological symptoms such as irritability, excitement, and irritability. 3. Some anorectal diseases are the main causes of bloody stools. Hemorrhoidal blood in the stool usually occurs during or after defecation, and appears as drops or spurts of blood. The blood is bright red and does not mix with the stool. Excessive blood in the stool may cause iron deficiency anemia. In more serious cases, symptoms include pale complexion, fatigue, loss of appetite, palpitations, and increased heart rate, which affect normal life and work, and also seriously endanger physical health. In addition, anal fissures, rectal polyps, colon polyps, ulcerative colitis, etc. can all cause blood in the stool. These are the main aspects of the dangers of blood in the stool. 4. Blood in the stool is also a signal of intestinal malignancy, that is, early rectal cancer. Since blood in the stool is similar to hemorrhoid bleeding, but it is difficult to distinguish from the symptoms of blood in the stool, some people do not pay much attention to blood in the stool, which makes the early malignancy easily ignored and leads to tragedy.
