Male anal bleeding after defecation

Many men have anal bleeding after defecation. Some are caused by hemorrhoids, and some are caused by intestinal diseases. Anal bleeding after defecation can cause serious damage to the anus. The patient will also feel very obvious pain in the anus, which also brings a lot of trouble to the patient's life. So, why does a man bleed from the anus after defecation?

1. Anal fissure

Anal bleeding, in addition to hemorrhoids, do not ignore anal fissure, which is also a common anal disease. The symptoms of anal fissure are generally blood in the stool. The blood is bright red, not too black, and it is painful after defecation. If the condition is severe, the pain may be more severe. If not treated in time, the condition will worsen. Anal fissure is actually similar to hemorrhoids and seriously affects daily life.

2. Rectal cancer (cancer)

If it is not hemorrhoids or anal fissures, you should consider whether it is colon cancer, because one of the symptoms of colon cancer is anal bleeding and black stools. In addition, colon cancer usually has a foul odor from the anus, accompanied by anal prolapse, pain, anal lumps, etc.

3. Gastric cancer

In the middle and late stages of gastric cancer, symptoms such as black stools and blood in the anus usually occur. Of course, if it is gastric cancer, it will also be accompanied by diarrhea, especially at night, when diarrhea is more severe. If you find that you have diarrhea more than twice at night and the stool is black, you cannot ignore whether it is gastric cancer.

The anus is a relatively private part of the body, so you must pay attention to its maintenance. Try not to wear tight underwear and keep the anus dry.

How to judge whether blood in stool is caused by intestinal cancer or other diseases such as hemorrhoids?

1. Changes in bowel habits

Changes in bowel habits, where a person who used to have a good bowel movement pattern suddenly becomes constipated or has diarrhea, alternating between the two. This is likely to be bowel cancer.

2. Stool with fishy smell

If the stool has a fishy odor and purulent blood during diarrhea, and the symptoms last for more than one month, you should be alert to the occurrence of intestinal cancer.

3. Judging the color of blood in stool

From the color of the stool, if the stool is dark or bloody, be careful whether it is an upper gastrointestinal tumor or intestinal cancer. If the bleeding color is brighter and the amount of bleeding is larger, the possibility of anorectal diseases such as hemorrhoids is higher.

4. Anal digital examination

Patients can also judge the nature of the disease by finger examination. If the surface feels cauliflower-like, it is more likely to be rectal cancer. If the surface feels smooth, it is hemorrhoids.

It is obviously related to the intake of "junk food" such as high calories, high fat, and high sugar. Excessive fat and animal protein interact with intestinal bacteria and bile salts to produce carcinogens. Low fiber intake slows intestinal peristalsis, less stool excretion, high concentration of carcinogens in the intestine, prolonged action time, irritation of the mucosa and resulting in cancer.

When symptoms of bloody stools appear, we must go to the hospital for a comprehensive examination in time to see if our condition is caused by hemorrhoids or rectal tumors. No matter what the disease is, early detection and early treatment will still have a good effect in treatment.
