If not, there is usually no need to be anxious. Drinking more warm water and taking rest can promote the body’s metabolism and help the metabolism and discharge of expired food, while paying attention to dietary hygiene and a light and easily digestible diet. If you have diarrhea, abdominal pain, nausea, fever, dizziness, or even dehydration or shock after consuming expired food, it is recommended to go to the hospital promptly, probably because the expired food has deteriorated and the food poisoning is caused by bacteria or toxins attacking the body after consumption. If the patient shows symptoms of violent vomiting and diarrhea, it is necessary to drink saline and other rehydration to prevent electrolyte disorders, and then saline, potassium permanganate, or sodium bicarbonate solution can be used to lavage the patient’s stomach to remove the poison from the body. After the treatment is completed, patients should take bed rest, drink more water, and eat mainly fluid or semi-liquid food to maintain the body fluid balance. Abstain from spicy, cold and other stimulating foods, which can help the recovery of gastrointestinal function. In addition, it should be noted that expired food should be avoided in life. Expired and spoiled food may already contain mold, bacteria or toxins, which can cause harm to the body.
