Symptoms of food poisoning occur, what are the symptoms after food poisoning?

Food poisoning usually occurs within 5 to 10 hours after eating food, and usually presents with symptoms of acute gastroenteritis, with nausea, vomiting and diarrhea, stomach pain, and sometimes pus and blood in the stool. If the vomiting and leakage are particularly severe, the body loses too much water, which may cause shock. Some patients also have chills, fever, sweating, salivation, and convulsions.

Sometimes poisoning occurs due to eating spoiled canned food, bacon, or sausages, which is due to a botulinum toxin bacteria contaminated in cured meat, which may produce a large amount of toxins, which can cause very serious neurological symptoms after eating.

Patients will spontaneously feel tiredness, weakness, headache, dizziness, difficulty seeing, unable to open their eyes, dilated pupils, difficulty swallowing or speaking, and paralysis of the hands and feet. Sometimes vomiting and diarrhea and stomach pain can lead to death within a few days if not treated quickly. Therefore, everyone should pay special attention when eating and drinking.

It depends on what kind of food poisoning is that the general symptoms are severe vomiting, diarrhea, and pain in the middle and upper abdomen, etc., but it is best to go to the hospital and see a doctor in time!!

The most common symptoms of food poisoning are severe vomiting, diarrhea, and pain in the middle and upper abdomen. People with food poisoning often have dehydration symptoms due to vomiting and diarrhea, such as dry mouth, sunken eye sockets, loss of elasticity, cold limbs, weak pulse, low blood pressure, etc., and finally shock.

Common symptoms of food poisoning are severe vomiting, diarrhoea, and pain in the middle and upper abdomen. People with food poisoning often experience symptoms of dehydration, dizziness, vomiting, diarrhea, and general weakness due to vomiting and diarrhea. The most common is vomiting and diarrhea.

Case: From 8 p.m. on October 31, 1987, the intestinal outpatient department of a district central hospital received more than 20 patients complaining of nausea, vomiting, abdominal pain and diarrhea for emergency treatment in a relatively short period of time**.

Question] 1.What could be the problem that an outpatient physician should consider? How to deal with it?

2.If food poisoning is suspected, how should it be confirmed? What to ask? What to do?

The intestinal outpatient department of the central hospital reported to the district health and epidemic prevention station at 11:30 that night, and the staff on duty at the district epidemic prevention station had received similar reports from several other hospitals in the district from 11 o'clock, so they reported to the duty room of the city health and epidemic prevention station, and asked the intestinal outpatient departments of each hospital to carefully understand the patient's eating situation and clinical characteristics, so as to further investigate and confirm whether it was food poisoning.

According to the outpatient physicians of various hospitals, the patient's clinical manifestations were mainly epigastric colic followed by diarrhea. Generally more than 10 times that night, the bloody stool is like washing meat, and some even turn into pus and bloody stool, tenesmus is not obvious, in addition to nausea and vomiting, some patients have chills, fever (fatigue, dehydration, etc., individual patients have toxic shock, acidosis, muscle spasms, etc., and each patient invariably said that at 6 o'clock that night in a famous hotel in the district to participate in the festive banquet held by relatives and friends, the dinner is particularly lively, the whole hotel upstairs and downstairs are crowded, there is almost no gap, and the guests may be as many as more than 100 tables.

Once you have considered food poisoning, what do you think should be done further?

Question] 3.According to the information provided by the clinician, what should the health station ask others to do further? [

Fever, shock, diarrhea, nausea and vomiting, abdominal pain, dehydration, metabolic acidosis. Food poisoning is characterized by a short incubation period, sudden and collective outbreaks, most of which are symptoms of gastroenteritis and are clearly related to the consumption of a certain food. Food poisoning caused by bacteria accounts for the vast majority.

The foods that cause food poisoning caused by bacteria are mainly animal foods (such as meat, fish, milk and eggs, etc.) and plant foods (such as leftover rice, soy products, etc.). Poisoning can also be caused by the consumption of poisonous animals and plants. Ingestion of improperly processed puffer fish can paralyze peripheral nerves and central nervous systems, and eventually die due to paralysis of respiratory centers and vascular movements.

Some vegetables containing a certain amount of nitrate, stored for too long or left for too long after cooking, bacterial multiplication will turn nitrate into nitrite, and after nitrite enters the human body, it can oxidize low hemoglobin in the blood to methemoglobin, lose the ability to deliver oxygen, and cause tissue hypoxia. In severe cases, death can occur due to respiratory failure. Moldy soybeans, peanuts, and corn contain aflatoxin, a metabolite of Aspergillus flavus, which is very toxic, it can damage the liver and induce liver cancer, so it cannot be eaten.

Poisoning can occur when ingested into food contaminated with chemicals such as lead, mercury, cadmium, cyanide and pesticides. Indiscriminate addition of nutrients in food is also harmful to the human body, such as in grains and cereals lacking lysine food, adding appropriate lysine, can improve the nutritional value, is beneficial to people. However, if it is added in excess, or in foods that do not require lysine such as milk and soy milk, it may disrupt the metabolism of amino acids in the human body and even cause damage to the liver.

The main way to prevent food poisoning is to pay attention to food hygiene, store food at low temperature, strictly disinfect and heat thoroughly before eating, and do not eat poisonous, spoiled animals and plants and food contaminated with chemicals. Patients with food poisoning should be sent to the hospital for treatment in a timely manner. 1 Since there is no process of infection between individuals, the onset of the disease is explosive, the incubation period is short, the onset is rapid, and most people may become ill in a short period of time, and the incidence curve shows a sudden upward trend.

2 Poisoned patients generally have similar clinical symptoms. Gastrointestinal symptoms such as nausea, vomiting, abdominal pain, and diarrhoea are often present3 and are food-related. After the patient had eaten the same food, the incidence was limited to the people who had eaten the poisonous food, and the onset stopped soon after stopping the food, and the incidence curve showed a sudden downward trend after a sudden increase.

4 Food poisoning patients are not contagious to healthy people.

Vomiting and diarrhea, severe stomach pain. If it is severe, the whole body is weak, and the head is sweating.

vomiting and diarrhea, having to go to the hospital for infusion, will be dehydrated.

Food poisoning refers to the adverse reactions of the body caused by the toxic substances in the food, including chemical poisoning, which can affect the health of the body in light cases and even endanger life in severe cases. Food poisoning is usually classified according to etiology into bacterial food poisoning, poisonous animal and plant food poisoning, chemical food poisoning, and mycotoxin food poisoning.

How to respond to emergencies Once you have an uncomfortable feeling in your stomach after eating, immediately use your fingers or chopsticks to help induce vomiting, and seek treatment from a medical institution in time.

Lentils contain saponin and other harmful substances, if you eat lentils that are not heated thoroughly, those who are mild poisoned can recover on their own after resting, or use licorice and mung beans to decoction as tea, which will have a certain detoxification effect.

People who accidentally ingest nitrite usually have chest tightness and breathlessness, so they should be rescued immediately, quickly enema, gastric lavage, catharsis, drink plenty of water, be sure to rest in bed, pay attention to keeping warm, and put it in a bad environment with fresh air and good ventilation.

Through medical history and physical examination, the doctor preliminarily determines whether it is food poisoning and what kind of food it may be caused by, and reports the situation to the health and epidemic prevention station in time, so as to rescue the patient on the spot as soon as possible.

Special tips Pay attention to personal hygiene, wash raw melons and fruits carefully, discard the rotten parts, wash hands and wipe hands with clean water or items before meals and after using the toilet.

When dining out, try not to choose unlicensed roadside stalls, but go to restaurants with good hygiene conditions and eat food that has been steamed at high temperatures for a long time.

The food made by yourself should be separated from raw and cooked, especially the utensils that come into direct contact with the food, such as cutting boards and knives, should be disinfected.

Refrigerated food should be kept quality and fresh, animal food should be thoroughly heated and cooked before eating, and it should also be fully heated before leftovers.

Do not use containers containing food to avoid accidental ingestion. Chemicals should be kept out of the reach of children.

Food poisoning manifests as nausea, vomiting, abdominal pain, diarrhea, general weakness, and dizziness.

predominantly, may be accompanied by fever. Patients with severe symptoms may have symptoms of dehydration and acidosis such as thirst and dryness, and even shock manifestations such as apathy, blood pressure drop, and oliguria. Or even death due to circulatory failure.

Food poisoning is an acute illness caused by eating food contaminated with bacteria or other toxins. The onset of the disease usually occurs a few hours after the right to eat, and a large number of people often develop it at the same time. Symptoms vary depending on the pathogen of infection.

Salmonella food poisoning can manifest as high fever, nausea, vomiting, abdominal pain, diarrhea, watery stools, etc., and in severe cases, convulsions and coma may occur, and death can occur if the rescue is not timely. It is often caused by eating meat, eggs, and aquatic products contaminated with bacteria, especially the meat of sick and dead livestock.

Vibrio parahaemolyticus food poisoning, acute onset, low fever, vomiting, abdominal pain, diarrhea, mostly recovered within a week. Poisoning can be caused by eating raw fish and crabs or eating meat, salted eggs, pickles, etc. contaminated with bacteria.

Staphylococcal enterotoxin food poisoning mainly manifests as nausea, vomiting, abdominal pain, diarrhea, etc., especially severe vomiting. It is often caused by eating dairy products, meat products, leftover rice, etc., which are contaminated with bacteria.

Botulism is short for Clostridium botulinum toxin poisoning and is the most severe form of bacterial food poisoning. In addition to dizziness, headache, nausea, vomiting and other symptoms, the main manifestations are blurred vision, diplopia, drooping eyelids, difficulty opening eyes, difficulty swallowing, hoarseness, etc., and death in severe cases. Fever is generally not present.

It is mostly caused by eating meat, eggs, salted fish, bacon, canned meat, stinky tofu, soybean paste, noodle sauce, etc. contaminated by bacteria.

Food poisoning is mainly caused by ingestion of food containing harmful bacteria. General food poisoning.

Manifestations include nausea, vomiting, acid reflux, abdominal pain, diarrhoea, and even allergies. Since the incubation period of different bacteria is different, the symptoms exhibited are also different. In general, the incubation period of common gastrointestinal bacteria generally ranges from 10 minutes to several hours; However, some bacteria, such as Vibrio haemolyticus food poisoning, can persist for several days.

The symptoms of food poisoning include gastrointestinal reactions, and then there are neurological reactions.

According to the classification of pathogenic substances, it can be divided into:

1. Bacterial food poisoning.

It refers to food poisoning caused by people ingesting foods that contain bacteria or bacterial toxins. There are many causes of food poisoning, the main and most common of which is bacterial contamination of food. According to the statistics of food poisoning in China in the past five years, bacterial food poisoning accounts for about 50% of the total number of food poisoning, and animal food is the main food that causes bacterial food poisoning, of which meat and cooked meat products rank first, followed by spoiled poultry meat, sick and dead animal meat, fish, milk, leftovers, etc.

There are several main reasons why food can be contaminated by bacteria:

1. Livestock are sick birds and sick animals before they are slaughtered;

2. Knives, cutting boards and utensils are unclean, and raw and cooked are cross-infected;

3. Poor sanitation and mosquito and fly breeding;

4. Food workers contaminate food with bacteria.

Food poisoning occurs when a person eats food contaminated with bacteria, but when a person eats a food contaminated with bacteria and multiplies on the food to a number that can cause disease or multiplies to produce disease-causing toxins, food poisoning occurs when a person eats such food. Therefore, another major cause of food poisoning is improper storage or prolonged storage at higher temperatures. The moisture and nutritional conditions in the food cause the growth of pathogenic bacteria, and if it is thoroughly heated before eating to kill the pathogenic bacteria, food poisoning will not occur.

Then, the last important reason is that it is not fully heated and undercooked before eating.

The occurrence of bacterial food poisoning is closely related to the dietary habits of people in different regions. The United States eats more meat, eggs and pastries, and staphylococcal food poisoning is the most; Japan likes to eat sashimi, and Vibrio parahaemolyticus has the most food poisoning; China eats more livestock and poultry meat and poultry eggs, and salmonella food poisoning has been the first place for many years. The originators of bacterial food poisoning include salmonine, staphylococcus, Escherichia coli, botulinum toxin, hepatitis virus, etc.

These bacteria and viruses can grow directly in food, or they can pass through the hands of food handlers or containers and contaminate other foods. When people eat these contaminated foods, the toxins produced by harmful bacteria can cause poisoning. Every summer, various microorganisms grow and multiply vigorously, and the number of bacteria in food is large, which accelerates its spoilage; In addition, people are greedy for cold and often eat food that is not fully heated, so summer is the season with a high incidence of bacterial food poisoning.

2. Mycotoxin poisoning.

Fungal food poisoning occurs when fungi grow and multiply in grains or other foods to produce toxic metabolites, and humans and animals eat humans. Poisoning occurs mainly through fungal contaminated food, and heat treatment with general cooking methods cannot destroy the mycotoxins in the food. Fungal growth and reproduction and toxin production require a certain temperature and humidity, so poisoning is often more seasonal and regional.
