How long does food poisoning take?

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

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

Mushroom poisoning

The type and dose of the toxin depends on how long the fungus poisoning manifests, the form and severity of intoxication. Consider the course and symptoms of the example of toxic cyclic peptides of fungi:

девушка собирает грибы Along with other cyclic peptides, the most toxic is alpha-amanitin (found in pale toadstool, mushrooms of the genus Lepiotus, mushroom, galerin). After complete absorption of this poison from the gastrointestinal tract into the blood circulation, after 4-24 hours the first symptom is observed - diarrhea. After some time, the position of the person stabilizes. After 48–72 hours, the level of glucose in the blood sharply decreases, tremor is observed, as well as yellowing of the mucous membranes and skin. Symptoms increase up to a coma in parallel with the progression of liver failure, due to toxic damage of hepatocytes.

Fatal outcome a maximum of a week after the lethal dose enters the bloodstream as a result of acute renal, hepatic, pulmonary insufficiency, hemorrhage and dystrophy of the cerebral cortex.

Drug poisoning

Overdose of antihypertensive drugs (for example, clonidine) causes a drop in blood pressure to a critical level. About an hour after taking it orally, general symptoms appear:

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

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

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

Poisoning with paracetamol containing drugs, especially in combination with alcohol, causes acute hepatitis. Again, how long the poisoning manifests itself depends on the dose. The first symptoms appear 2–4 hours after administration:

  • nausea;
  • vomiting;
  • lack of appetite.

Within 24–48 hours, pain in the liver area is typical, and in case of severe overdose, after 2 days, liver and renal failure begins to develop, and gastroenteritis and pancreatitis are possible. In the worst case, death after 7 days from liver failure.

Insulin poisoning

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

  • инсулин malaise;
  • diffused consciousness;
  • dilated pupils;
  • tachycardia;
  • convulsions;
  • blurred vision;
  • pronounced tremor;
  • and at the end - hypoglycemic coma.

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

Alcohol poisoning

After taking 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 stays at this point for 120 minutes. If alcohol was taken with food, the absorption time increases significantly to 1.5–2 hours. The effect of alcohol is exacerbated by the parallel increase in blood concentration. First appears:

  • отравление алкоголем feeling of euphoria;
  • this is followed by clouding of reason;
  • lack of coordination of movements;
  • mood changes radically, aggressiveness is manifested;
  • vomiting reflex.

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

Food poisoning

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

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

Symptoms may persist for several days. Depending on the cause of intoxication, after how many hours food poisoning manifests itself, the outcome can be even fatal.

Chlorine poisoning

отравление хлором в бассейне In case of chlorine poisoning, respiratory failure develops due to lesions of the upper segments of the lungs and respiratory tract, periodic respiratory arrest of a criminal nature, and after 120–240 minutes - pulmonary edema. Agony is accompanied by irritation of the mucous membranes, cough, acute pain in the chest.

Exposure to ultra high concentrations of chlorine leads to convulsions, weakening of sphincters - involuntary bowel movements and urination. Loss of consciousness, and then death, occurs in minutes due to swelling of the larynx from a poisonous gas and, as a result, suffocation.

Conclusion

Considering the symptoms and possible results, it is necessary to avoid exposure to poisonous gases, carefully dose the medications 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!
