Enteritis is an acute inflammation of gastrointestinal tract caused by bacteria or other reasons, and it is one of the most common gastrointestinal diseases in summer and autumn. This disease is easy to occur in places and families with poor sanitation. Acute onset, with vomiting, diarrhea and abdominal pain as the main symptoms. The common pathogenic bacteria are Salmonella, halophilic Bacillus and Staphylococcus. The disease is divided into four types: simple, corrosive, infectious and suppurative.

The common causes of simple gastroenteritis are as follows:

1.Physical stimulation. If you overeat, the food you eat is too hot, too cold and too rough, which can cause gastric mucosal damage and inflammatory changes.

2. Chemical stimulation. If you ingest strong liquor, strong tea, coffee, spicy food and rich spices, or take salicylates, sulfonamides, antibiotics (especially tetracycline, chloramphenicol and erythromycin), digitalis, indomethacin, reserpine, anticancer drugs and adrenocortical steroids, you can damage the gastric mucosa.

3. Eating food contaminated by bacteria or other toxins. Recently, it has been found that most cases are caused by viruses. Generally speaking, factors such as drinking a lot, fatigue, catching cold and mental stimulation are often the inducement of the disease, which leads to the low defense function of the body, so that bacteria and viruses invading the intestine take the opportunity to multiply and grow, or cause disease because of the strong virulence of bacteria and viruses and the large number of bacteria. In addition, acute gastroenteritis can also occur when the human body is under severe stress, such as severe trauma, surgery, infection and shock.
