What are the dangers of bleeding from stage 4 anal fissure

If the anal fissure has reached stage four, it means it is already quite serious and heavy bleeding may occur. Stage 4 anal fissure will cause anal ulcers and other pathological changes, which pose a great threat to the health of the anus and require timely treatment and care.

4-stage classification: According to the pathological changes of anal fissure, it can be divided into four stages:

1. Initial stage: Anal fissures caused by the above factors initially present as superficial damage to the skin of the anal canal, or superficial ulcers, and the tissues around the wound are basically normal.

2. Ulcer formation stage: There is unhealthy granulation proliferation in the wound. Annular fibers are seen at the wound bottom and skin hyperplasia is seen at the wound edge.

3. Chronic ulcer stage: The wound is an old ulcer and the internal sphincter can be seen after sectioning.

4. Chronic ulcer combined with other pathological changes: On the basis of chronic ulcer, there are latent anal fistula, etc. Chronic anal fissure is often combined with the following pathological changes.

What are the dangers of stage 4 anal fissure?

1. Pain: Anal fissure can cause periodic pain due to defecation, which is the main symptom of anal fissure. When defecating, the feces stimulate the nerve endings on the ulcer surface, and the patient immediately feels a burning pain in the anus. But the pain will ease after a few minutes of defecation, and this period is called the pain interval. Later, severe pain will occur again due to spasm of the internal sphincter. This period can last from half an hour to several hours, making the patient restless and very difficult to bear. Until the sphincter is tired, the muscles relax and the pain is relieved, but the pain will occur again when defecating again.

2. Constipation: This is both the cause and consequence of anal fissure. After anal fissure, the patient is unwilling to defecate due to anal pain, which causes constipation over time and the stool becomes drier and harder. Constipation can also aggravate anal fissures, forming a vicious cycle and making it difficult for anal fissures to heal.

3. Blood in stool: When defecating, a small amount of fresh blood or drops of blood are often seen on the surface of the stool or on toilet paper, which can easily lead to anemia over time.
