Anal bleeding

If you find yourself bleeding from your anus when defecating, you should go to the hospital for a check-up as soon as possible. This may be a symptom of anorectal disease. If it is not treated in time, it may develop into a tumor. In this case, it will become quite troublesome and will cause people to lose appetite and lose weight, which means that it has entered the late stage.

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 (no bowel movement, no flatulence, vomiting, abdominal masses, abdominal pain) may occur. 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.

1. Anal fissure: Anal fissure causes obvious blood in the stool to the patient, and generally the fissure will worsen to a certain extent, making the symptoms of blood in the stool more obvious. The degree of damage to the fissure will directly affect the intensity of anal bleeding and pain.

2. Internal hemorrhoids: The first symptom of internal hemorrhoids is obvious blood in the stool. This is mainly due to the long-term presence of hemorrhoids, which leads to a continuous increase in secretions. When it develops to a certain extent, blood in the stool will occur. Patients with internal hemorrhoids will have relatively obvious blood in their stools in the early stages, and pain will occur in the later stages.

3. External hemorrhoids and mixed hemorrhoids: These two types of hemorrhoids can also cause anal bleeding, but the symptoms are milder than internal hemorrhoids, and the pain symptoms are much more obvious.

4. Anal fistula: Most of the time, anal bleeding occurs when the symptoms are relatively mild. When patients with anal fistula experience anal bleeding, it means that the symptoms of anal fistula are showing a trend of worsening. Therefore, when diagnosing and treating the disease, patients still have to use professional methods and try to cure the disease well in a short period of time.
