Sometimes it happens that a person himself can not see blood in the stool, as there are no visible traces. Usually this happens when the blood in the intestine and in the feces itself comes from the upper parts of the digestive system, that is, reaching the end, it manages to change the color.

Hemoglobin, which is present in the blood, decomposes under the influence of acids, and therefore the feces literally acquire a black color. The main reasons for this phenomenon include:

  • Bleeding from the enlarged veins in the esophagus. In addition to the fact that the chair changes color, it will also become tarry. To that, right after eating, a person will have severe pain behind the sternum, vomiting with blood
  • Mallory-Weiss Syndrome, in which a bloody fissure is formed in the esophagus or in one of the stomach parts. Usually, it happens with drinking people or with those who do not treat a stomach ulcer
  • Bleeding from a stomach ulcer or duodenal ulcer when the stool can be several times a day, and black. In addition, the person will be hurt, and also the temperature of the body may increase.
  • The perforation of duodenal ulcers, in which a person's condition will be as if he lost a lot of blood, that is, dizziness, weakness, unconsciousness. In addition, in the feces will be present blood
  • Gastric cancer, especially in the last stages. It can be accompanied by other symptoms, such as weakness, anemia, aversion to any meat products
  • Tumors of the esophagus that are currently in the decay stage of
  • Stomatitis, both in adults and in children

That is why, one's health should be treated with awe and listen to the body in time to notice any changes and consult with a specialist about this.

Diagnosis of altered blood in the feces

Blood in the feces can be secretive

And if in the case of visible blood in the stool there is no need for special diagnostics, as everything is visible, then in the case of the altered it is necessary to undergo a series of studies to make sure,that it is blood, not the influence of certain foods. The most important analysis, which allows you to determine whether latent blood is in the stool or not, is Gregersen's analysis, or in another way, Gragersen's reaction.

In order to pass this study, it is necessary to prepare. It is impossible to clean the teeth, eat meat and fish three days before putting the feces, and also take any vitamins that contain iron. Then a person collects feces, and a special mixture is applied to his surface, which makes it possible to reveal blood.

If, after applying a chemical substance, it changes color to blue or green, it means that there is blood in the feces. In the event that there was no change in color, then everything is fine. After such a reaction was carried out, the doctor will look for a source of bleeding.

Causes of blood in the stool in children

Children are no different from adults. And if many people think that they simply can not have some problems, they are deeply mistaken. The child's organism is absolutely the same as the adult organism. The only difference is only in the size of the organs. Therefore, all of the above reasons can be used for children. However, it must be remembered that basically the blood in the feces of children can appear for the following reasons:

  1. Dysbacteriosis of the intestine. To date, this is one of the most common problems in children of any age, since, despite the propaganda of healthy nutrition and the availability of a variety of food products for children( mixtures, sticks, etc.), not all parents adhere to this. And there are those who feed the baby with soup in half a year. As a rule, dysbacteriosis in children appears after taking antibiotics, when the course of bifidobacteria was not drunk. To accurately anticipate that the cause of blood in the feces is a dysbacteriosis, it is necessary to pass tests for bacterial culture. After the results are obtained, the doctor will prescribe the treatment. But most importantly, it is some time to observe the correct diet, exclude all products-irritants
  2. Intestinal obstruction. One of the most dangerous causes of the presence of blood in the feces of the child will be intestinal obstruction, which occurs as a result of frequent constipation, congenital anomaly, malnutrition, early introduction of complementary foods. Most often, the obstruction is diagnosed in children under two years of age. If we talk about the symptoms of manifestation, immediately after eating the child will loudly and cry a lot, and then, after a while, just vetch a fountain. To this symptom is also added a frequent stool with mucus and blood. But after a couple of hours the chair will turn into a dangerous lump of mucus with blood. From this moment begins the most dangerous stage, during which, if not to call an ambulance, the child completely refuses water and food, will fall into a state of shock.
  3. Food allergy. Often parents notice that they poured food on a child and a baby on the skin. But sometimes allergies can be manifested by the presence of blood in the feces, and also with a foamy stool. As a rule, such a manifestation can be if the child uses milk, citrus, various food supplements
