The first signs of intestinal infections in children and adults

With severe symptoms of acute inflammation of the intestinal mucosa, an intestinal infection predominates in the body of an adult and a child. Do not ignore the unpleasant signs of extensive damage to the digestive tract, otherwise there is a general intoxication of the body. With intestinal disorders, you must urgently consult a doctor to determine the viral etiology of the disease and select a treatment regimen. Superficial self-medication of an adult and a child is strictly contraindicated.

What is an intestinal infection?

This is an extensive group of diseases that systemically affects the digestive tract. Such a health problem can occur in childhood, but also extends to adult patients. With bacterial infection of the digestive system, the chemical composition of the intestinal microflora changes, as a result of which the mucous membrane is irritated, and an inflammatory issue occurs. The stomach may hurt, but more often these are severe signs of dyspepsia.


Pathogenic microorganisms in medical practice are different, but equally destroy the mucous membrane of the digestive tract. The disease of viral etiology progresses, for successful treatment it is required to find out the nature of harmful microorganisms. The most dangerous are salmonella infection, staphylococcus, intestinal flu, streptococcus, Escherichia coli, increased activity of enterovirus infections. Of the diseases, dysentery, salmonellosis, typhoid fever, and escherichiosis should be feared. An unpleasant consequence is the presence of viral diarrhea.


Signs of intestinal infection in adults and children progress spontaneously, can be the main reason for hospitalization. There is such a need against the backdrop of spontaneous dehydration, when the health effects of an adult patient and a child are most unpredictable. It all depends on the severity of the disease, the nature of the pathogenic pathogen. Among the characteristic symptoms of an intestinal infection, doctors distinguish the following changes in overall well-being:

  • cramping, paroxysmal abdominal pain;
  • the presence of helminthic infestations;
  • chronic constipation;
  • complete lack of appetite;
  • increased irritability, nervousness;
  • disturbed phase of sleep;
  • weakened immunity;
  • progressive iron deficiency anemia;
  • teeth grinding at night;
  • nausea, less often – bouts of vomiting.

In children

With a violation of the intestinal microflora, dehydration of the body develops, which is manifested by acute diarrhea, a sharp increase in temperature, signs of fever. There are different cases, but the main task of parents is to immediately call a pediatrician at home if severe symptoms of intestinal infection in the child are observed. Alternatively, these may be:

  • fever, nausea, which are accompanied by frequent vomiting;
  • drowsiness, increased irritability;
  • sharp pains in the stomach, complemented by cramps.

The reasons

To ensure a speedy recovery, it is necessary to find out the pathogenic factors that cause poisoning and lead to dangerous dehydration of the body. In viral infections, there is an alimentary mechanism of infection, while there are several pathways of infection – fecal-oral, household, airborne droplets. In order to finally get rid of the disease, timely treatment is necessary, but antibiotics are not always prescribed by specialists. The causes of pathologies that affect the gastrointestinal tract are as follows:

  • contaminated food or household items;
  • swimming in open water;
  • violation of personal hygiene;
  • unsanitary conditions;
  • genetic predisposition.


According to the etiology of the pathological process, doctors apply the classification of lesions of the gastrointestinal tract with protozoal intestinal microbes, increased activity of rotavirus and staphylococcal infections, and viability in the stomach of any intestinal infections. in addition, the effects of toxin poisoning should not be ruled out. According to the characteristics and duration of the pathological process, there are chronic and acute intestinal infections. In the first case, the occurrence of unpleasant symptoms is spontaneous, in the second – sluggish.

According to the nature of the pathogenic pathogen, the following classification of intestinal infection in children and adults is distinguished:

  • the bacterial nature of intestinal infections: salmonellosis, dysentery, typhoid fever, botulism, cholera, yersiniosis, a consequence of staphylococcal poisoning from food;
  • viral: adenovirus, enterovirus, rotavirus, reovirus, coronavirus infection;
  • protozoan, in which the increased activity of pathogenic microbes can provoke amoebiasis, giardiasis.


If you ignore the progressive health problem, after a couple of months of mild symptoms, the doctor will diagnose a chronic disease, and an intestinal infection is difficult to treat effectively, often reminds of lingering diarrhea. The following clinical pictures become more dangerous complications for the patient’s health:

  • complete dehydration of the body;
  • dehydration shock with a possible fatal outcome;
  • infectious toxic shock;
  • acute renal failure;
  • pneumonia.


An integrated approach to a health problem is needed to determine diarrhea of bacterial origin. It is important to correctly differentiate a characteristic ailment, highlight from an extensive list of diseases of the digestive system with similar symptoms. For example, it is shown to distinguish nonspecific ulcerative colitis or pathogenic intestinal neoplasms. In order to determine the nature of pathogenic bacteria, a number of laboratory and clinical examinations are required.
