Why is the stool red and not blood?

Red stool is actually a normal situation sometimes, because it is possible that it is not blood but a type of stool formed by some other substances. However, after this happens, we should still pay close attention to our human body, because it may also be a symptom caused by some diseases or due to some other reasons. So what if the stool is red and not blood?

Considering gastrointestinal dysfunction, it is recommended to eat a light diet recently, eat less greasy and sweet food, avoid spicy, stimulating, raw and cold food, and avoid drinking. It is recommended to use Zhengchangsheng and Shuliqineng to adjust the medication. It is recommended to take the two medicines regularly for one week. Drink more thick yogurt on a daily basis. It is recommended to drink yogurt at room temperature after meals. Pay attention to eating habits and work and rest habits.

Blood in the stool may be caused by small intestinal lesions, but more often it is bleeding in the sigmoid colon and rectum. In terms of the nature of the lesion, tumors, inflammation, deformities, etc. can all cause bloody stools. The brighter the red, the closer the bleeding site is to the anus.

The occurrence of bloody stools in middle-aged and elderly people, especially those with recent onset, should be taken more seriously than in young people. This is because with age, the number of neoplastic lesions (both benign and malignant) in the sigmoid colon and rectum increases significantly.

Hemorrhoids: If you have external hemorrhoids, you can feel a soft nodule at the anus, but you cannot feel internal hemorrhoids. The amount of bleeding is heavy and not mixed with the stool. Sometimes there is only blood stain on the toilet paper. The bleeding is often related to dry stool or excessive force during defecation.

Rectal and colon cancer: These diseases have increased significantly in recent years, and the incidence rate has increased by 2-3 times. At the beginning of the disease, a small amount of blood can be seen covering the surface of the stool. As the disease progresses, the amount of blood in the stool gradually increases, the stool may become thinner, and even intestinal obstruction may occur (no bowel movement, no flatulence, vomiting, abdominal masses, abdominal pain). The stool may have a special odor produced by pus, mucus and cancerous tissue. When systemic symptoms appear, such as decreased appetite, weight loss, edema, anemia, etc., the disease is already in the late stage.

Ulcerative colitis: The blood may be bright or dark in color, and almost every stool is mixed with blood and pus. There are often abdominal pain and diarrhea, which may recur or persist for a long time.

Colorectal polyps: Some are benign, while others are prone to malignant transformation (such as adenomatous polyps and villous adenomas). The incidence rate increases with age and may occur singly or multiple times. Blood in the stool is often intermittent and bright red in color. Generally, the amount of blood is not large and the blood is not mixed with the stool. There are no special changes in the stool itself.

Colonic vascular dysplasia: more common in middle-aged and elderly people, bleeding is mostly fresh blood, the amount of bleeding is large, and there is no change in the stool itself.
