What are the symptoms of food poisoning?

The most common symptoms of food poisoning are severe vomiting and diarrhea, accompanied by pain in the middle and upper abdomen. People with food poisoning often experience symptoms of dehydration due to vomiting and diarrhea, such as dry mouth, sunken eye sockets, loss of skin elasticity, cold limbs, weak pulse, low blood pressure, etc., which can eventually lead to shock. Therefore, the patient must be hydrated, and normal saline can be given if conditions permit. Patients with mild symptoms are allowed to rest in bed. If you only have stomach discomfort, drink more warm water or diluted salt water, and then put your hand into your throat to induce vomiting. .If you find that the poisoned person has shock symptoms (such as cold hands and feet, blue complexion, decreased blood pressure, etc.), you should lie down immediately, raise your lower limbs as much as possible, and ask a doctor for treatment as soon as possible. Chemical food poisoning Chemical food poisoning mainly refers to food poisoning caused by toxic metals, non-metals and their compounds, pesticides, nitrites and other chemical substances contaminating food. Chemical food poisoning is mainly caused by accidentally ingesting toxic chemicals or ingesting food contaminated by chemical substances. The main characteristics of chemical food poisoning are: (1) Rapid onset. The incubation period is short, usually ranging from minutes to hours, and a few may exceed one day. (2) The degree of poisoning is severe, the course of the disease is longer than that of bacterial toxin poisoning, and the morbidity and mortality are higher. (3) Seasonality and regionality are not obvious. Food poisoning is non-specific and is mostly caused by accidental eating or ingestion of food contaminated by chemical substances, which is more accidental. Bacterial food poisoning Bacterial food poisoning is food poisoning caused by people eating food containing a large number of live bacteria or bacterial toxins. It is the most common type of food poisoning. The main characteristics of this type of food poisoning are: (1) It usually has obvious seasonality and mostly occurs in hot seasons, usually in the months of May-October. On the one hand, higher temperatures create favorable conditions for bacterial reproduction; on the other hand, the body's defense capabilities are reduced during this period and susceptibility increases, so bacterial food poisoning often occurs. (2) Foods that cause bacterial food poisoning are mainly animal foods, such as meat, fish, milk and eggs; a few are plant foods, such as leftover rice, glutinous rice cakes, fermented noodles, etc. (3) People with reduced resistance, such as the weak, the elderly and children, are prone to bacterial food poisoning, with a higher incidence rate and more severe acute gastrointestinal inflammation. However, this type of food poisoning has a low mortality rate and a good prognosis. Symptoms and rescue of food poisoning ① Anyone who eats food contaminated by bacteria (such as salmonella, staphylococcus, E. coli, botulinum toxin, etc.) and their toxins, or eats food containing toxic chemicals, or food It contains natural toxins (such as pufferfish, poisonous mushrooms, sprouted potatoes, etc.). Acute toxic diseases caused by these causes are called food poisoning. Food poisoning mostly occurs in summer and autumn when the temperature is high. Food poisoning can occur both individually and collectively (for example, in canteens and banquets). ②The most common symptoms of food poisoning are severe vomiting and diarrhea, accompanied by pain in the middle and upper abdomen. People with food poisoning often experience symptoms of dehydration due to vomiting and diarrhea, such as dry mouth, sunken eye sockets, loss of skin elasticity, cold limbs, weak pulse, low blood pressure, etc., which can eventually lead to shock. Therefore, the patient must be hydrated, and normal saline can be given if conditions permit. Patients with mild symptoms are allowed to rest in bed. If you only have stomach discomfort, drink more warm water or diluted salt water, and then put your hand into your throat to induce vomiting. .If you find that the poisoned person has shock symptoms (such as cold hands and feet, blue complexion, decreased blood pressure, etc.), you should lie down immediately, raise your lower limbs as much as possible, and ask a doctor for treatment as soon as possible. ③Those who eat pufferfish will experience numbness in their tongue or hands and feet 2 to 3 hours after eating. If you induce vomiting earlier, the effect will be better, and you will be rushed to the hospital for emergency treatment. If delayed for more than 4 hours, respiratory paralysis and death will occur. In addition to gastrointestinal symptoms, poisonous mushroom poisoning can also cause symptoms such as convulsions, drooling, hallucinations, and trembling hands. In first aid, induce vomiting first and then send the patient to the hospital. ④ If it is a collective poisoning, the rescue work must be organized. The health and quarantine department should also be notified quickly for quarantine. It is best to keep leftover food for diagnosis, treatment or quarantine.
