In the case of mild food poisoning, recovery is usually around 3 days; if symptoms are severe, it may take 5 to 7 days or even longer. If food poisoning occurs, it may be caused by eating unclean food, spoiled food or expired food. If the symptoms of food poisoning are mild, such as diarrhea, you can drink plenty of plain water to speed up the body’s metabolism and promote the elimination of toxins, and you can usually return to normal in about 3 days. If the food poisoning is more serious, it may take 5 to 7 days or even longer to recover. If food poisoning causes serious complications, such as shock, multiple organ insufficiency, etc., the recovery time will be even longer and the exact recovery time cannot be generalized. The symptoms of food poisoning can be observed first. If the symptoms of poisoning are found to be more serious, it is recommended to go to a regular hospital as soon as possible for consultation and treatment to avoid serious consequences.
