The most common causes of "gastrointestinal cold" are viral infection and dietary allergic reaction. Bacteria and viruses will swallow into the gastrointestinal tract along saliva after implantation and inflammation in the throat, causing gastrointestinal discomfort. Its symptoms are as follows: 1 vomiting 2 diarrhea 3 abdominal pain.

Treatment: 1. Anti-inflammatory drugs: ciprofloxacin and rijunsha can be used for satisfactory gastrointestinal effects, ribavirin and morpholine hydrochloride can be used for fever reduction, and paracetamol can be used for first aid for severe stomach cramps. The treatment of gastrointestinal cold is mainly rest. On the one hand, patients should rest more, reduce physical exertion, and enhance the body's strength against diseases.

2. On the other hand, let the gastrointestinal tract get a full rest. Reducing the burden on the stomach and intestines is to restore digestive function as soon as possible, and then increase food intake. On the contrary, it will only increase the burden on the gastrointestinal tract and become chronic gastroenteritis over time. Under normal circumstances, dieting for a week or so will not cause any concern about undernutrition. When early vomiting is obvious, intravenous fluid replacement can be appropriate, and the rest can be treated as a cold. Appropriate use of hunger therapy, but to supplement water, it is best to drink more salt and sugar water, at least 500 ml a day.
