How long does food poisoning last?

пищевое отравление According to statistics, only 20% of people seek medical help for food poisoning. Meanwhile, according to the World Health Organization, the fatal outcome of the disease occurs in one case out of a hundred.

How long does food poisoning last and what are the features of the disease course? What is dangerous for a toxicological infection and in what cases it is necessary to consult a doctor?

Features of the course of food poisoning

Food poisoning proceeds according to the general scheme. The duration of the disease directly depends on the amount of poor-quality food and the effectiveness of therapeutic measures. Of course, important is the type of pathogen or toxin. But it should be noted that approximately 45% of intoxications remain with an unclear reason.

All food poisonings have similar clinical signs and a mechanism of disease development. They are united by:

  • sharp beginning;
  • mass character;
  • all cases are related to the consumption of one product;
  • rapid course of the disease;
  • favorable outcome, with the exception of botulism.

It is believed that acute intoxication occurs more easily and ends faster than those whose symptoms develop more slowly. How long a poisoning lasts depends on many factors.

Lightweight infections

отравление Light poisoning is accompanied by a single vomiting and a slight disorder of the stool. Body temperature remains within normal limits. Such a disease takes two to three days. The body is quickly released from toxic elements and digestion comes back to normal.

For about two weeks after the disease, it is necessary to maintain the stomach and intestines, observing a sparing diet and restoring the microflora of the intestinal tract.

An easy degree can be caused by the use of unwashed fruits, poor-quality seafood, dairy and fermented milk products.

Severe course of poisoning

With botulism, salmonellosis, staphylococcus, intoxication with poisonous fungi, food toxic infections are very difficult. Threatening symptoms are:

  • рвота indomitable vomiting;
  • persistent diarrhea or the presence of blood in the stool;
  • temperature 39 ° C and above;
  • disorders of the nervous system: convulsions, paralysis, visual impairment, drooling;
  • drop in blood pressure, fainting;
  • suffocation;
  • changes in the amount and quality of urine.

At such signs it is necessary to address immediately in a hospital!

How long does the temperature last for poisoning depends on the causative agent of the infection and the effectiveness of the treatment. If the proteus or staphylococcus is affected, the temperature may not rise or pass within 1-2 days. With salmonellosis, this period can last up to 3-5 days, and when poisoning with fungi, the temperature goes away when vomiting and severe diarrhea stop.

With a favorable course, food poisoning of microbial etiology is an average of 7-10 days. How long intoxication lasts depends mainly on the degree of intestinal damage and the functioning of the liver, as the main detoxification organ. If the liver is in good condition, then recovery is faster.

Factors complicating the course of poisoning

отравление пожилого человека Food poisoning in children and the elderly is more severe. According to statistics, about 75% of all fatal cases are children under 14 years old. Also, the process of recovery in people suffering from severe chronic illness will be slower.

A major role in the process of intoxication is dehydration of the body due to loss of fluid with vomiting and diarrhea. Some toxins (for example, poisons of pale toadstool) have a destructive effect on liver cells, thus triggering a severe pathological process. The poison can already be removed from the body, and signs of intoxication continue to gain strength. Therefore, the forecast is based on the speed and dynamics of the manifestation of symptoms.

If there is a sharp diarrhea and vomiting, which then go to decline - the disease will flow easily and will take place in a few days. In the case when the symptoms are manifested 6-24 hours after the use of suspected products, and diarrhea, vomiting and other disorders are only intensified within a few hours - the disease will be severe and will require treatment for 10-14 days, plus 2-4 weeks to restore the digestive system.

Food poisoning often begins suddenly. If the symptoms appear abruptly, within a few hours after consuming the poisonous product and then go on to decline - then the disease proceeds to an easy degree and will last 2-3 days. If there are adverse symptoms - indomitable diarrhea and vomiting, changes in the cardiovascular and respiratory system, an increase in body temperature above 39 ° C, then poisoning will be difficult. Hospitalization and thorough treatment are necessary. Such poisoning will last 7-10 days, and 2-4 weeks will be needed to restore the disturbed functions of the body.
