It often happens that a person has a very strong diarrhea with blood, which has a watery consistency. The reasons for this development of diarrhea may be different, but all of them are serious enough, and therefore require an immediate request to a specialist for the necessary diagnostic examination in this case and to identify the prerequisites that provoked the patient's liquid stool of this type. With the treatment of this ailment can not be delayed in any case, since in the development of pathology, due to the disrupted integrity of the intestinal mucosa, there is a rapid penetration of the infection into the body, and the loss of blood that occurs regularly, usually leads to iron deficiency anemia. Many patients wonder why diarrhea occurs with blood?

Black, watery stools( melena) with clots are usually a sign of internal bleeding, the source of which is located in the upper parts of the intestine, as they manage to curdle up to the exit, as their structure and dark color indicate. Among the diseases that caused the bloody diarrhea, include stomach ulcers or duodenal ulcers, malignant tumors of the same departments or cirrhosis.

In addition, to the patient's question, why diarrhea with blood lasts for him not the first day, any specialist immediately assumes to undergo an examination for infectious intestinal diseases. Viruses and bacteria very often cause a loose stool with blood. In this case, in addition to very frequent attacks of diarrhea( up to 20 times a day), the disease will be accompanied by fever, chills, weakness and nausea, alternating with vomiting. In addition, the pathology in the intestinal microflora is indicated by the release of a large amount of mucus, which promotes the excretion of pathogenic microorganisms.

In addition to these two most common factors, due to which a person can have a liquid stool with blood, the reasons for it depend on the formation of cracks in the anus, oncopathology, polyps and bulging of the intestinal wall. The concomitant symptomatology of these types of diarrhea can manifest itself in painful sensations localized in the rectum area, amplified by acts of defecation or upon their completion. Painful sensations are often accompanied by temperature and vomiting.

Especially dangerous is diarrhea with blood, the causes of which lie in serious diseases. Diarrhea in this case is accompanied by fever and pain in the abdomen. Such symptoms unambiguously indicate that a person develops dysentery, salmonellosis or some other dangerous disease. With the appearance of such signs, any independent treatment is unacceptable. Urgent need to see a doctor. To properly diagnose the cause of bloody diarrhea, radiography and endoscopy should be performed, and when mucus having red color is allocated, urgent hospitalization is necessary.

Diarrhea with blood after antibiotics

When the cause of a loose stool with blood becomes a prolonged course of treatment with potent drugs, the appearance of diarrhea is usually associated with the fact that antibacterial drugs provoked accelerated reproduction and the development of the Clostridium difficile microbe. This microorganism becomes the cause of such a dangerous disease as pseudomembranous colitis, which in approximately 5% of cases leads to a fatal outcome. This pathology arises both after the end of the course of treatment, and during it. At risk are patients of older age( from 60 years).

What is this ailment and why can it develop after the beginning of the course of antibiotics, thus causing a person diarrhea with blood? This pathology is characterized by the development of a specific dysbacteriosis, leading to a severe inflammatory bowel disease, in which fibrous plaque is formed on its walls. The resulting imbalance of the microflora causes bleeding damage to the mucosa caused by the toxins produced by this bacterium and watery diarrhea.

Also in antibiotic-associated bloody diarrhea caused by potent drugs, there may be a microbial association with fungi such as Staphylococcus, Klebsiella or the genus Candida. Patients often ask why antibiotics cause bloody diarrhea. The reasons for this lie in the combination of suppression of the growth of both normal and pathogenic microflora, which is present in the human digestive system. But the risk of a liquid stool having a red color is not directly related to the amount of antibiotic that has accumulated in the body after the course of treatment.
