After what time is food poisoning manifested

отравление Poisoning occurs when a toxic agent that breaks homeostasis and interrupts physiological mechanisms enters the body, which may prove incompatible with life.

The amount of poison is determined after what time symptoms of poisoning with fungi , drugs, alcohol, various chemicals appear. Let's figure out how long the first signs of poisoning from different toxic substances begin to appear.

Poisoning with mushrooms

From the type and dose of toxin depends through what time is manifested by fungal poisoning, the form and severity of intoxication. Consider the course and symptoms of toxic fungal cyclic peptides:

After full absorption of this poison from the gastrointestinal tract into the circulation, after 4-24 hours the first symptom is diarrhea. After a while, the person's position stabilizes. After 48-72 hours, the blood glucose level drops sharply, there is a tremor, as well as yellowing of the mucous membranes and skin. Symptoms grow right up to the coma in parallel with the progression of liver failure, due to toxic damage to hepatocytes.

The lethal outcome is a maximum of one week after a fatal dose has entered the bloodstream as a result of acute renal, hepatic, pulmonary insufficiency, hemorrhage and dystrophy of the cerebral cortex.

Drug poisoning

Overdose of antihypertensive drugs (on the example of clonidine) causes the decline of blood pressure to a critical level. After about an hour after oral ingestion, general symptoms appear:

  • medikamentoznoe otravlenie weakness;
  • drowsiness;
  • impaired vision and coordination of movements.

After 2-3 hours palpitation and breathing slow down significantly, consciousness is lost. Depending on the dose, within 6-12 hours from the moment of poisoning, complete depression of respiration and palpitation with a fatal outcome can occur.

Intoxication with hypnotic drugs (for example, zolpidem) causes symptoms from confusion, to coma, for 30 minutes-2 hours. In case of a significant overdose, respiratory and cardiovascular system are depressed, death occurs within the next 3-6 hours.

Poisoning with paracetamol containing drugs, especially in combination with alcohol, causes acute hepatitis. Again, after what time the poisoning manifests itself, depends on the dose. The first symptoms appear 2-4 hours after taking:

  • nausea;
  • vomiting;
  • lack of appetite.

Within 24-48 hours, pain in the liver region is typical, and with a severe overdose, liver and kidney failure develops in 2 days, and gastroenteritis and pancreatitis are also possible. In the worst case, a lethal outcome after 7 days from liver failure.

Insulin poisoning

The introduction of a high dose of this hormone after 60-120 minutes causes hypoglycemia - a drop in the blood glucose level to a critical level. First appear:

  • инсулин malaise;
  • distracted consciousness;
  • dilated pupils;
  • tachycardia;
  • convulsions;
  • blurred vision;
  • severe tremor;
  • and in the end - a hypoglycemic coma.

When an insulin overdose slow action, the effect is less pronounced and with a delay of 6-10 hours.

Alcohol poisoning

After receiving an excessive amount of ethyl alcohol on an empty stomach, its concentration in the blood reaches a peak value after 0.5-1.5 hours and holds at this point for 120 minutes. If alcohol was taken with food - suction time is significantly increased to 1.5-2 hours. The effect of alcohol is aggravated in parallel with the increase in concentration in the blood. First appears:

  • отравление алкоголем a sense of euphoria;
  • further follows the clouding of reason;
  • violation of coordination of movements;
  • radically changing mood, aggressive;
  • vomiting reflex.

After 120 minutes, a coma develops with cardiac and respiratory insufficiency. If the concentration of alcohol in the blood is about 4.0 ‰ or more, a person dies without regaining consciousness for 10-20 hours.

Food poisoning

The amount of food taken depends on how quickly food poisoning manifests itself. Vomiting and diarrhea occur in the period of 30 minutes to 6 hours. In 24 hours:

  • пищевое отравление dizziness;
  • tachycardia;
  • hyperthermia;
  • headache;
  • severe spasms.

Symptoms can last for several days. Depending on the cause of intoxication, after how many hours food poisoning manifests itself, the outcome can be up to lethal.

Poisoning with chlorine

отравление хлором в бассейне When chlorine poisoning develops respiratory insufficiency due to the defeat of the upper segments of the lungs and respiratory tract, periodic stops of breathing of a criminal nature, and after 120-240 minutes - pulmonary edema. Agony accompanies irritation of the mucous membranes, cough, acute pain in the chest.

The effect of ultrahigh concentrations of chlorine leads to convulsions, weakening sphincters - involuntary bowel movement and urination. Loss of consciousness, and then death comes in a few minutes because of the laryngeal edema from the poison gas and, as a consequence, suffocation.


Given the symptoms and possible outcomes, you should avoid exposure to poisonous gases, carefully dose drugs and take into account their interactions with other substances, monitor the quality and composition of food. In case of signs of intoxication - immediately consult a doctor!
