Anxiety is a loose stool with blood

If the blood in the stool with constipation can be the result of mechanical damage to the walls of the intestine, the liquid stool with blood is an alarming symptom requiring an immediate qualified examination of the patient's condition.

Rectal bleeding gives rise to suspected serious abnormalities in the functioning of the body, but can have completely innocuous causes, which, nevertheless, it is important to find out.

A simplified understanding of diarrhea is a loose stool that accompanies various states of the human body, usually infectious diseases.

Consistency does not fully characterize diarrhea. The second sign is the frequency of bowel movements: diarrhea is said to occur when it reaches more than three times a day.

The third most important characteristic is the volume of stools exceeding the daily norm( 200 ml).

Another sign of diarrhea - bowel movements must contain feces, for example, with cholera, frequent loose stool can reach 10 liters a day, but consists of mucus, and not feces, so it is technically not diarrhea.

But in determining the rate and pathology, it is not the frequency, consistency and other characteristics that are important, but changes in the usual defecation order.

Individual features of some people provide defecation three times a day, and others - three times a week, but both can be quite healthy.

It is worth worrying about the changes in the frequency of defecation, the degree of stool formation, odor, color, with the appearance of additional impurities - veins of blood, pus, remnants of undigested food and so on.

Diarrhea causes a deficiency of fluid and electrolytes in the body, and this is its main danger.

The balance is broken when the stool is unformed, but with the liquid the process is more rapid. Diarrhea up to two weeks is considered acute, more than three weeks - chronic.

Any medical student will easily determine the source of diarrhea. Eight liters of liquid enter the intestine every day.85% is absorbed from the small intestine, the remaining 15%( about a liter) - from the thick.

With abundant diarrhea, the small intestine "flows", the watery stool abruptly and foul smells, it can be seen pieces of undigested food, the stomach in most cases does not hurt. Pain can indicate a lesion of the large intestine.

Another difference in diarrhea depending on the place of occurrence is the frequency of defecation. The closer the source of diarrhea to the anus, the less a person can restrain defecation.

If feces are many, but hiking in the toilet are rare, then the problem is probably in the small intestine. With disrupted the operation of the large intestine, the feces are generally scarce, but it is much more common to run to the toilet.

There are 4 main causes of diarrhea:

1. secretory activity of intestinal walls;
2. increased osmotic pressure in the gut;
3. exudation resulting from increased permeability of the intestinal wall;
4. decrease or excessive increase in motor activity of the intestine.

Depending on the mechanism, there are four types of diarrhea. Abundant, too loose stools distinguish secretory diarrhea.

The same high-water, but greasy( sticking to the smooth faience of the toilet), the stool is characteristic for osmotic diarrhea.

Lean fluid stool with an admixture of blood and mucus is an occasion to suspect exudative diarrhea. A lean or poorly designed lean chair characterizes diarrhea due to accelerated or delayed bowel motility.

The most frequent causes of blood in the stool

The doctor should be consulted with a sharp increase in body temperature, strong, especially pulsating abdominal pain, with severe dehydration that can not be replenished at home, in cases of prolonged diarrhea - longer than three to four days.

Admixtures of blood and mucus in the feces determine the need to consult a specialist, because it is impossible to understand in absentia the source of blood in the stool.

The color of the stool will help to determine the cause or source of bleeding. If krovit from the upper sections of the digestive tract, the feces will be black, tarry.

This is due to the reaction of hemoglobin and sulfuric acid in the composition of gastric juice in case of bleeding in the ulcer of the stomach or duodenum. The red color of blood in the stool means that the source of bleeding is below the cecum.

In both colors, stool can stain food products or medications, for example, because of the presence of food colors in their composition.

The chair with blood in the child happens quite often, basically it is not dangerous.

The vast majority of cases of rectal bleeding in children is associated with two causes:

1. a crack in the intestinal mucosa near the anus. It can happen because of a copious stool or as a result of constipation, both in a newborn and an adult. The blood is scarlet, fresh;
2. is an allergic reaction due to intolerance to cow and soy protein. As a rule, by the end of the first year of life, children successfully develop this problem.

Other causes of a loose stool with blood in adults and children: ulcerative colitis( inflammatory process in the large intestine) and Crohn's disease.

The mucous membrane becomes inflamed, diarrhea develops, possibly with blood veins or evenly stained with blood, weight may decrease as a result of a decrease in appetite.

Intestinal infections can also cause rectal bleeding. The causative agents of the disease may be bacteria, viruses or parasites.

Without careful examination, treatment with antibiotics is unacceptable - they do not act on viruses and parasites, so they can only worsen the situation by changing the balance of the intestinal microflora.

Observing the blood streak in the feces, it should be borne in mind that the cause may be a course of antibiotics. If you or your child just go through such treatment, then tell the doctor about the reaction.

Blood in the stool can appear due to polyps in the large intestine, formed during abnormal growth of the intestinal mucosa.

Juvenile polyps can occur in children 2 to 8 years old, they also occur in adults. Since there is a risk of malignant degeneration of such formations, in many cases surgical treatment is required.

Rectal bleeding is a part of the clinical picture of more serious diseases, therefore it is a symptom, the explanation of which is extremely important.

Where is the blood in the liquid stool?

In the diagnosis of bowel diseases, it is very important to have an anamnesis. If there is a suspicion of inflammatory bowel disease( IBD) - ulcerative colitis and Crohn's disease - or oncology it is important to study the presence of these diseases in the family.

For rectal bleeding, a general picture of the patient's condition should be studied, paying special attention to the medications that the patient takes. Blood thinning medications can cause blood in the liquid stool.

Doctors exclude the infectious nature of the disease by studying stool in various ways. A stool culture is made, which gives information on pathogenic bacteria in the intestinal microflora.

The analysis of feces for eggs of worms and the simplest microorganisms is done, since infestations are one of the causes of the appearance of blood in the feces.

The feces are analyzed for leukocytes and epithelium. In a healthy person, the preparation can detect only single white blood cells, an increase in their number produces an inflammatory process, localized in the intestine.

It is extremely important to collect the feces correctly for analysis, as the white blood cells can get into the material for examination from the urethra or from the vagina, which will distort the picture of the disease.

Epithelial cells lining the intestinal mucosa. Normally, a small amount is present in the stool as the epithelial layer is renewed. An increase in the number of epithelial cells will tell the doctor about the inflammatory lesion of the mucosa.

In the presence of diarrhea, it is necessary to examine whether there is polypheic, that is, whether the amount of feces exceeds the norm of 200-300 ml.

Another important diagnostic indicator - the presence of steatorrhea - increased excretion of fats with feces.

The type of steatorrhea will show which fats are in the stool - neutral or fatty acids, which will make the diagnosis.

Survey of the patient, the study of his analysis, the study of the symptoms gives extensive diagnostic information, but in many cases the doctor needs to see what is inside.

For this, the following methods are used:

• sigmoidoscopy, which allows to study the nearest to the anal opening of 60 cm of the large intestine;
• colonoscopy is the study of the entire large intestine;
• enteroscopy - methods of internal examination of the small intestine, which are made through the mouth or through the anus - depending on the organs that are of more interest to the doctor in terms of diagnosis.

Ultrasound of the abdominal cavity organs, fluoroscopy, magnetic resonance imaging, biopsy of intestinal tissues and many other methods are used.
