The key is the kind of food poisoning. If food poisoning is treated timely or symptomatic antidotes are applied, there will be obvious therapeutic effect and the patient’s symptoms will be significantly improved. However, such as poisoning by consuming some poisonous mushrooms, especially fatal gooseberries, the mortality rate is extremely high. The principles of treatment of food poisoning are as follows: 1. If gastric lavage is given in time within eight hours of poisoning, the mortality rate can be reduced. 2. If gastric lavage is not given for a long time or if severe food poisoning occurs, along with obvious failure of various organs, a series of comorbidities of other organ insufficiency will appear, such as obvious acute damage to liver function and kidney function when food poisoning occurs. For example, acute impairment of liver and kidney function can occur in food poisoning. In patients with previous liver and kidney failure or cardiac insufficiency, there is an increased risk of complications and risks.
