Blood from the anus during bowel movement: causes and treatment, prognosis

Blood from the rectum during bowel movements in rare cases goes unnoticed by patients. Usually, the sight of blood on toilet paper puts a person in shock and makes you seriously think about your health. Such a symptom can signal diseases of the colon.


Causes of blood from the anus during defecation

Causes of blood from the anus during defecation

The appearance of blood from the anus during defecation in women and men occurs in the following pathological conditions:

  • Anal fissure ;
  • Inflammation of hemorrhoids;
  • Intestinal polyps ;
  • Malignant tumors of the colon;
  • Gastrointestinal bleeding on the background of peptic ulcer, Crohn's disease, ulcerative colitis;
  • Chronic constipation;
  • Proctitis or paraproctitis ;
  • Worm infestation ;
  • Salmonellosis;
  • Dysentery;
  • Enterovirus infection;
  • Impaired blood clotting function;
  • Leukemia and others.

All these causes pose a threat to the patient's health, since if the underlying disease is not treated, the bleeding will increase, and the pathological process itself will turn into a chronic form. Permanent discharge of blood from the anus is fraught with the development of iron deficiency anemia, general weakness and reduced immunity.

Signs and Symptoms

disease symptoms

Staining of feces with blood is always a sign of a disease, and the color of blood indicates indirectly the location of the pathological process.

In this case, the causes of the appearance of blood from the anus in women are exactly the same as in men, except during pregnancy. The main rule in self-diagnosis - the brighter the color of blood in the feces, the closer to the anus the focus of the disease.

Scarlet blood from the anus is most often caused by an anal fissure or inflammation and trauma of hemorrhoids, while dark brown or black blood indicates bleeding in the upper gastrointestinal tract.

More: fecal occult blood test

Blood from the anus without pain is most often seen with erosive injuries of the large intestine or bleeding duodenal ulcer. Painless bleeding from the anus can be signs of polyposis in the large intestine.

The blood in the stool, depending on the reason for its appearance, is accompanied by the following clinical symptoms:

  • Sharp acute pain in the anus during straining and an act of defecation - this symptom is most characteristic of anal fissure. After defecation, bright red blood remains on the paper, and the patient may be plagued by chronic constipation due to fear of pain recurrence;
  • Feeling of a foreign object in the anus, feeling of heaviness, pressure, pain when emptying the bowel, protrusion of hemorrhoids to the outside when straining. In the feces there is an admixture of bright blood in the form of streaks;
  • Diarrhea, vomiting, fever, frequent urge to defecate (in most cases false), feces in the form of rectal "spittle", an admixture of blood and mucus in the feces - these clinical symptoms are characteristic of dysentery;
  • Spastic abdominal pain, fever, vomiting, diarrhea, increasing weakness, blood in the stool and large amounts of mucus - similar symptoms occur with salmonellosis and various enteroviral infections.

In almost all cases of anal bleeding, the patient has a reduced hemoglobin level in blood tests and clinical symptoms of iron deficiency anemia are observed:

  • Weakness;
  • Lethargy;
  • Fast fatiguability;
  • Palpitations;
  • Pallor of the skin;
  • Dyspnea;
  • Loss of consciousness or fainting;
  • Fragility of hair and nails;

Blood from the anus: treatment and prognosis

Treatment of blood from the anus during defecation

Treatment of blood from the anus depends on the causes of the pathological discharge. When blood from the anus appears, the doctor will first of all collect a thorough history of the patient's life, after which he will schedule a detailed examination, including:

  • Complete blood count (pay special attention to the level of hemoglobin);
  • Ultrasound of the digestive tract;
  • X-ray of the large intestine with the introduction of a contrast agent;
  • Endoscopic examination of the upper parts of the digestive tract;
  • Consultation proctologist and digital examination of the rectum.

Most of the diseases in which there is a release of blood from the anus during feces are not fatally dangerous for the patient - but they should not be ignored, since the pathological process can progress or become chronic.

Timely diagnosis and treatment of the underlying disease prevents possible complications and saves the patient from the presence of blood in the stool.

Treatment of bleeding from the anus, depending on the reasons for the appearance:

  • With hemorrhoids, the patient is prescribed a means of local action - rectal suppositories, creams, ointments with anti-inflammatory effect;
  • With varicose veins of the anus - topical preparations that improve blood flow, cold compresses, baths with decoctions of herbs;
  • In chronic constipation - medical nutrition, microclysters, adherence to drinking regime, laxative drops and mild tablets that act directly in the rectum;
  • Infectious and inflammatory diseases - antibiotics, antiviral drugs, washing the stomach and intestines;
  • In duodenal ulcers - proton pump blockers, coating agents, diet;
  • Ulcerative colitis - clinical nutrition, anti-inflammatory drugs;
  • With anal fissure - ointments and creams of local action with wound-healing and regenerating effect, as well as painkillers in the form of rectal suppositories.

The patient should carefully monitor the regular emptying of the intestines, since constipation and stagnation of the feces in the rectum contribute to the aggravation of the underlying disease.

Blood from the anus in pregnant women

In women during pregnancy, the load on the pelvic organs and lower limbs increases significantly. Since the growing uterus puts pressure on the large blood vessels, it can lead to stagnation in the limbs and the development of varicose veins .

Varicosity in turn provokes the expansion of the veins of the anus and the development of inflammatory processes of hemorrhoids. The most common cause of blood from the anus during pregnancy is hemorrhoids.

In addition, due to the relaxation of the smooth muscles of the pelvic organs by prostaglandins, expectant mothers have to suffer from constant constipation, as a result of which anal fissures can form against the background of difficulties with emptying the intestines. These cracks cause severe pain to the woman and the release of red blood from the stool.

It should be remembered that pregnancy itself is a serious test for the woman’s body, therefore, during the period of gestation of a baby, long-standing chronic diseases of the gastrointestinal tract can worsen.

Blood from the anus in women who are expecting a baby may occur as a result of the resumption of gastric or intestinal peptic ulcer, polyposis or bleeding erosion, as well as other diseases of the gastrointestinal tract.

What to do when separating blood from the anus?

Of course, when blood appears from the anus, the patient should consult a doctor as soon as possible. The specialist will determine the exact cause of the discharge and prescribe the appropriate treatment.

Sometimes the bleeding from the intestines can be quite abundant, intensify and cause increasing weakness in the patient. In this situation, you should immediately call an ambulance, stay in bed, do not use hot water bottles and do not put on an enema - all these procedures can only increase the bleeding.

To establish the cause of bleeding from the intestines of the patient must be hospitalized in the hospital, where he undergoes a detailed examination and subsequent adequate treatment.

To what doctor to address at allocation of blood from an anus? - Independently you can refer to the proctologist.
