Gastrointestinal infections can develop from taking contaminated food transmitted from an infected person through hands contaminated with feces, food and water, the source of infection may be meat and eggs. The best prevention of such infections is good hygiene.
Why start gastrointestinal infections
Gastrointestinal infections are always a consequence of entering into the body of certain pathogens. Thus, the cause of acute gastritis is most often the poor quality food, so this infection is called food poisoning.
Intestinal infections occur in the transmission of pathogens of bacterial or viral origin from the patient to health through dirty hands, food and water.
Gastrointestinal infections - that occurs in the body
When gastrointestinal infections in the patient develops the following picture. Toxins pathogens affect the cells of the mucous membrane of the stomach and intestines, violating their basic functions. In addition, toxins and improper digestion products inhibit the activity of some enzymes, breaking the wall digestion process.
Under the action of toxins break down the proteins of cell membranes, the permeability of the intestinal walls and toxins penetrate deeper into the intestinal wall. As a result, in the intestinal lumen formed biologically active substances that have strong toxic influence on the blood vessel wall of the intestine. Violated microcirculation first in the gut, and then (for severe infections), and throughout the body.
Under the influence of toxins by increased fragility and permeability of small blood vessels, blood stagnation occurs, thrombosis

vessels and hemorrhage. Poor circulation leads to disruption of cell metabolism in tissues, cells accumulate in toxic products of incomplete metabolism and changes in acidity - metabolic acidosis.
The same violations of the microcirculation in the liver, which leads to disruption of its functions. A major function of the liver is to neutralize poisons and when it is broken, toxins freely enter the blood, causing a general intoxication.
Stagnation of blood in the capillaries and leads to the fact that part of the fluid, minerals and plasma proteins begin to leak from the vascular space into the extracellular and then in the intestinal lumen and excreted. In severe gastro-intestinal infections, diarrhea is constant, but without stool - is excreted blood plasma, which leads to dehydration.
The loss of large amounts of fluid leads to disruption of the cardiovascular system. In order to fill the vascular system of a liquid, there is vasospasm of skin (the patient becomes very pale) and muscle spasm, allowing to "squeeze" the liquid from the intercellular space. Due vasospasm decreases as fluid excretion by the kidneys.
The kidneys suffer because of the toxic effects and reduce blood volume, a hundred further enhances effects of acidosis, the payment of which is due to the activation of respiration.
Exposure to toxins, poor blood circulation, lack of oxygen and acidosis lead to dysfunction of the brain. Growing headache, there are violations of consciousness, seizures, and hypovolemic (amid a sharp reduction in circulating blood volume) shock, which can lead to death of the patient.
Acute gastritis and gastroenteritis - food poisoning
Very often the cause of food poisoning are Salmonella that enter the body via contaminated food (pies, cakes, creams, not fully processed animal flesh, eggs) and water. Peak food poisoning is in the summer.
The disease begins in one to three days after infection - the time required for adequate reproduction in the gut pathogens. It begins food poisoning

with nausea, vomiting, abdominal pain, fever, chills, headache, malaise. After some time, diarrhea joined to 10-15 times a day. The patient pale, with a strong intoxication may appear jerking and impaired consciousness.
This period is dangerous because the loss of large amounts of fluid from the stool and vomit of the patient may become dehydrated. Another complication of salmonellosis
Salmonellosis - features of the disease
- The emergence of foci of inflammation in the internal organs - the infection spreads to the bloodstream. After suffering food poisoning may be a significant decrease in immunity.
Treatment of acute gastritis and gastroenteritis - drinking plenty of fluids, light food, symptomatic and restorative treatment. If the diagnosis is confirmed salmonellosis prescribe antibiotics

. After recovery is necessarily spent examination of feces for the presence of an infectious agent.
Gastrointestinal infections are dangerous because it is difficult to predict when and to what extent can worsen the patient's condition.
