It should be acute gastroenteritis. Every summer is the frequent season of acute gastroenteritis. Due to high temperature and humidity, food is easy to rot and deteriorate. Inadvertently letting bacteria and viruses invade the stomach and intestines will make patients vomit, diarrhea and abdominal pain, which is very uncomfortable. The incidence of acute gastroenteritis is high in summer and autumn in China, and the general incubation period is 12-36 hours. Therefore, in daily life, especially in summer and autumn, we should pay attention to food hygiene and actively prevent the occurrence of acute gastroenteritis. The main clinical manifestations of acute gastroenteritis are nausea, vomiting, abdominal pain, diarrhea and fever. In severe cases, dehydration, electrolyte disorder and shock can be caused. Most patients first show nausea and vomiting, followed by diarrhea, ranging from 3-5 times a day to even dozens of times. Most stools are watery, dark yellow or light green, and have a foul smell, which may be accompanied by abdominal cramps, fever, body aches and other symptoms. Once acute gastroenteritis occurs, you should stay in bed as much as possible and take glucose and electrolyte orally to supplement the loss of body fluids. If vomiting persists or dehydration is obvious, glucose saline and other related electrolytes should be added intravenously. Eat light liquid or semi-liquid food to prevent dehydration or treat mild dehydration. If necessary, antiemetic drugs can be injected: for example, intramuscular injection of 25- 100 mgl of chloropropane every day; Spastic drugs: such as belladonna 1 3 times a day; Antidiarrheal drugs: such as smecta 1 bag, 1 2-3 times a day. For infectious diarrhea, targeted antibiotics, such as berberine or gentamicin, can be appropriately selected, but to prevent the abuse of antibiotics after the acute symptoms of acute gastroenteritis disappear and recover does not mean that the digestive tract function is completely restored to normal. At this time, diet therapy is very important. After acute inflammation, gastrointestinal congestion and edema have not completely subsided, and secretion and digestive tract function have not fully recovered. Therefore, if you eat foods that are not easy to digest, such as greasy or spicy food, the digestive ability of the gastrointestinal tract can't adapt, and a series of digestive symptoms will appear, such as fullness and discomfort in the upper abdomen and anorexia. For example, if acute gastroenteritis begins to eat normally after the initial recovery, even eating greasy and spicy food or drinking alcohol, the gastrointestinal tract that has not recovered its function will be overwhelmed, and some will turn into chronic gastrointestinal diseases, such as chronic gastritis and chronic diarrhea. Generally, within 5-7 days after acute gastroenteritis, according to the different situation of each patient, harmful factors should be avoided first: quitting smoking, drinking, strong tea, coffee and so on. Eat less spicy and rough food, don't overeat, and eat less drugs that are irritating to the gastrointestinal tract. Secondly, the diet advocates three meals a day, and each meal should not be too full, so as not to increase the burden on the stomach. Generally, senior people should eat light liquid and semi-liquid foods, such as rice soup, porridge, fresh fruit juice, etc., and gradually supplement some protein foods, but avoid greasy and fried foods, eat a small amount at first, and then start eating normally after gastrointestinal function is restored, and pay attention to rest. At the same time, according to different symptoms, we can also choose some Chinese patent medicines such as Huoxiang Zhengqi Water, Baohe Pill, Xiang Lian Huazhi Pill and Ginseng Jianpi Pill to improve the symptoms. Most patients with acute gastroenteritis have mild symptoms, and they can be cured in about a week after reasonable treatment and diet adjustment. However, a few patients with acute gastroenteritis can cause shock and even life-threatening because of the virulence of pathogenic bacteria. If you have acute gastroenteritis, you should go to the hospital in time to avoid delaying your illness and causing unnecessary adverse consequences. I wish you a speedy recovery! ! .
