BLEEDING FROM THE RETURN CHANNEL

There are various district causes of bleeding from the posterior outlet canal in men. Bleeding from the posterior canal is often the result of disease or injury to the lower part of the colon. However, this condition can also be caused by other diseases that are not related to the gastrointestinal tract.

Causes of bleeding

So what causes bleeding from the rectum, what causes bleeding after diarrhea or before diarrhea, what measures should be taken in this case, which doctor should be consulted? We hope you find answers to such questions below.

Bleeding from the posterior duct during or before diarrhea, the presence or absence of pain, abdominal pain, and the appearance of sticky mucus in underwear may be reasons to seek medical attention.

This condition can be caused by simple mucous membranes, hemorrhoids or, in severe cases, bowel cancer, leukemia and other life-threatening diseases.

However, there are cases when bleeding from the back canal can be a reason to call an ambulance. They can be:

• Rising body temperature with bleeding, severe abdominal pain;

• If the patient's general condition worsens due to bleeding from the anus, there is a disturbance of consciousness, general weakness;

• In addition to bleeding from the anus, bleeding into the subcutaneous layer (accumulation of blood even if no injuries occur), bleeding from the nose;

• Suspicion of life-threatening blood clotting, high blood volume, or blood loss;

• If bleeding is accompanied by nausea and vomiting, blood is also found in the vomit mass.

All of the above are life-threatening processes that are specific to the acute phase of injury, infection, or somatic disease, in which case no independent treatment is required and immediate medical attention is required.

What diseases can be a sign of back bleeding?

Bleeding from the rectum during diarrhea can be a symptom of many diseases. The anamnesis should clarify questions such as whether the bleeding occurred during or before diarrhea, whether there was pain syndrome, whether the blood was dark or light in color.

If dark red blood flows during diarrhea, it is from the lower part of the rectum, and if the blood is very dark, accompanied by black stools, it indicates a pathology of the upper gastrointestinal tract.

The sex of a person does not play a significant role in the causes of bleeding. However, bleeding in women due to venous thrombosis during pregnancy can be a sign of the onset of labor.

Hemorrhoids

The disease is more common in older people (40-50 years old), and in women it usually occurs after childbirth or during pregnancy. Pregnancy is characterized by hormonal imbalances in the body, which affect the elasticity of the vascular wall, causing the fetus to squeeze the gastrointestinal tract, digestive disorders, diarrhea, constipation and dilation of the venous caverns around the anal canal.

The disease often begins to manifest itself after birth. Hemorrhoids can become inflamed or thrombosis. Constipation further complicates the process.

During diarrhea, there is bleeding from the enlarged venous cavities in the lower part of the rectum, pain syndrome, itching of the anal canal and discomfort.

The first stage of the disease may be asymptomatic, with only a feeling of discomfort during diarrhea. However, in the later stages of hemorrhoids, the enlarged venous cavities bleed constantly, chronic anemia develops, and this requires surgery.

The amount of blood flowing depends on the severity of the disease: in the early stages, the blood volume is not large, but when it reaches the final level, the amount of blood flowing is large, which can aggravate the patient's general condition. Therapeutic procedures are performed by a proctologist, the most effective treatment of the disease is surgery.

Anal porridge

Chronic constipation is caused by the development of pus around the anal canal or in the mucous membrane. Diagnosis is usually made by collecting a medical history and visual inspection and palpation. The patient has severe pain and small blood droplets in the stool.

Treatment is with diuretics, analgesics, regenerative drugs, and sphincter relaxants. Adjustment of diet, prevention of constipation, personal hygiene of the anal canal are also among the preventive measures. If such operations are not performed, drug treatment will not be effective. If anal pain is severe, surgery may be needed.

Inflammatory diseases of the intestine

One of the symptoms of nonspecific ulcerative colitis and Crohn's disease is bleeding from the anal canal. In addition, there is pain in the abdomen, diarrhea, fluid and bloody stools, the development of comorbidities (arthritis, dermatitis, liver dysfunction).

Such diseases require systemic treatment, otherwise the risk of developing cancer is very high. Hormonal drugs, drugs that reduce the activity of immune cells and painkillers are used in the treatment of drug menopause. It is necessary to normalize the process of digestion and diarrhea.

Bleeding due to intestinal and systemic infectious diseases

Infectious diseases also cause bleeding from the anus. For example, enteroviruses and rotaviruses, especially in men, cause bleeding, which can lead to irritation of the intestinal mucosa, inflammation, and erosions. In this case, the bleeding may not be due to diarrhea.

Typhoid fever, dysentery, hemorrhagic fever, changes in blood formula, and massive internal bleeding can also cause bleeding from the posterior duct. In this case, immediate medical attention should be sought and patients should be isolated (epidemic isolation). In such cases, the risk of death is very high.

Invasion of helminths

Excessive accumulation of parasites in the intestines disrupts the integrity of the mucous membranes, leading to bleeding from the injured area. The patient's general condition gradually worsens and chronic anemia may also develop.

Parasitic diseases cause a decrease in the body's general immunity, allergic reactions, increased susceptibility to respiratory viral and bacteriological diseases, and dysfunction of internal organs. Patients should be treated in an inpatient setting when bleeding due to gel invasion is detected.

Which specialist should be consulted if bleeding from the posterior outlet canal?

Patients can be examined by a therapist and proctologist if the bleeding volume is not high, if the patient's general condition does not worsen, and if the above-mentioned grounds for immediate hospitalization are not observed. If necessary, the advice of an infectious disease specialist, gastroenterologist and other specialists will be needed.

Occasionally, clear blood droplets may not be visible in the stool, and if blood is flowing from the upper gastrointestinal tract, the blood may mix with the stool until it reaches the anal canal, and the stool may be dark black in color.

The following tests can be performed to determine the cause of bleeding:

• Retroscopic examination;

• Colonoscopic examination;

• Irrigoscopic examination (contrast-enhanced radiography of the intestine);

• Gastroduodenoscopy;

• Laproscopic examination.

A small amount of blood in the stool is not a sign of a dangerous disease. However, failure to diagnose and treat such a condition in a timely manner, or to treat it independently, can lead to severe disease. In this case, the patient's life may be endangered.

The most common causes of posterior hemorrhage are:

Gastrointestinal systemic diseases	Infectious-parasitic diseases	Diseases of the blood and blood coagulation system
Hemorrhoids, anal canal porridge, wounds;	Enterovirus, rotovirus infection;	Leukemia;
Erosive form of gastritis, bleeding from the gastric mucosa due to ulceration;	Dysentery, typhoid fever, hemorrhagic fever, salmonellosis;	Leukemias;
Esophageal veins varicose expansion;	Sexually transmitted infections of the intestines infection;	In the mesenteric blood vessels thrombus formation and others.
Complications of cirrhosis of the liver; Tumors, polyps of the gastrointestinal tract; Crohn's disease, nonspecific ulcerative colitis; Tuberculosis of the intestine.	Effects of herpes virus; Bleeding as a result of parasite invasion.
