What is the cause of bleeding from the toilet large size ?

Anal bleeding should not be taken lightly.

Many people usually instinctively think that they have hemorrhoids if they have bleeding after defecation, so they buy a plaster at a random pharmacy to have a meeting, or use home remedies for treatment. There are many people who think "nothing is great"; Indeed, the causes of anal bleeding are mainly due to hemorrhoids, anal fissures, hemorrhoidal fistulas, etc.; However, it is worth mentioning that some anal bleeding may hide a major disease, so it should not be careless and underestimated! Here's a brief look at the common conditions that cause anal bleeding:

1 Anal cancer and lower bowel cancer bleeding.

The incidence of anal cancer and rectal cancer has increased rapidly in recent years, and once the disease occurs, symptoms such as constipation and blood in the stool occur. As the surface of the rectum becomes carcinocarcinous to a certain extent, the tumor begins to necrosis and then bleeds, usually during bowel movements, and blood is excreted with the stool.

2 Hemorrhoids bleed.

Anal bleeding, caused by hemorrhoids, usually occurs during bowel movements. Blood drip out when the anus is tightly tightened, and some bleeding is in the form of a jet, and if the bleeding is slight, there are blood stains on the toilet paper during the anal wiping process after defecation.

From the point of view of symptoms, sometimes soft lumps can be palpated when bathing, and they disappear when pushed in the direction of the anus, and they reappear during defecation, but when the symptoms are severe, the anus is red and swollen, and the protruding hemorrhoids cannot be plugged back.

3 Anal fissure hemorrhage.

Bleeding caused by anal fissures varies from the degree of bleeding to the degree of blood dripping on the toilet paper, especially when the stool is dry, bleeding is often accompanied by anal tingling, so stinging sometimes people do not appear until a few minutes after defecation.

Anal fissures are located at the posterior edge of the anus, and longitudinal fissures can be seen in the senses.

4 Hemorrhoidal fistula bleeding.

If there is a small amount of bleeding during bowel movements, a lump around the anus, and pus discharge, a hemorrhoidal fistula may have formed. Once an anal fistula is formed, it may induce malignant transformation and cause anal cancer after it becomes chronic, so it is recommended that surgical excision is an effective measure to prevent anal cancer when patients have hemorrhoidal fistula.

All in all, the diseases that cause anal hemorrhage, in addition to anal cancer, rectal cancer, hemorrhoids, anal fissures, hemorrhoidal fistulas, rectal colorectal polyps, colorectal diverticulum, perianal dermatitis, etc. can also cause bleeding, among which anal cancer and rectal cancer are fatal diseases, as long as the principle of early detection and early treatment is pursued, the survival rate is still very high, and rectal polyps may be transformed into cancer.

If there are no hemorrhoids.

That's an anal fissure, pay attention.

Wash after defecation, anti-inflammatory treatment, contraindication of spicy diet.
