Have loose bowels after drinking cold drinks. Why?

Infectious diarrhea, commonly known as diarrhea, is a group of infectious diseases with abdominal pain and diarrhea as the main clinical manifestations caused by viruses, bacteria, molds, parasites and other pathogens. Infectious diarrhea 1 ~ 2 days can heal itself, and severe diarrhea can die of dehydration and septic shock, especially in infants and the elderly. Most infectious diarrhea is contagious, such as bacillary dysentery and cholera. Therefore, the national disease prevention and control department requires hospitals to open diarrhea clinics from May 1 day every year to control the impact of infectious diarrhea on more people in society. Why is infectious diarrhea prone to occur in summer? How can I keep myself away from infectious diarrhea? 1. High temperature and humidity in summer are good environmental conditions for bacteria, viruses and parasites. Leftovers, leftovers and fruits in summer are more likely to deteriorate than in winter, which is caused by the breeding of certain bacteria and molds. 2. In summer, the vectors of intestinal infectious diseases such as flies and cockroaches breed in large numbers. These vectors often move back and forth between garbage, feces, toilets and food, fruits and vegetables, restaurants and food stalls, carrying and spreading pathogens. 3. A large number of seasonal fruits and vegetables are on the market in summer, which greatly increases people's chances of eating raw fruits and vegetables. No matter how it is cleaned, eating raw fruits and vegetables will bring more germs into the body than heating cooked food, which will pose a threat to the sick, infants and the elderly. 4. The hot weather, sweating a lot and drinking a lot of water dilute the stomach acid and reduce the resistance of the gastrointestinal tract. Pathogens that enter the body through the mouth cannot be killed by stomach acid. Normal people's gastric juice is acidic, which can kill most pathogens eaten, and the human body will not get sick. Drinking a lot of cold drinks has a greater impact on gastric acid, because cold drinks can cause gastric mucosal blood vessels to contract and gastric acid secretion to decrease. In summer, there are many kinds of food stalls on the street, which are convenient and affordable, making diners linger like clouds. However, food stalls can't run to wash dishes, there are no fly prevention facilities, the streets are dusty, and food hygiene is out of control. Every summer, diarrhea clinics treat such patients. At six or seven o'clock in the evening, they will drink draft beer at street food stalls and go to the hospital for intravenous drip because of abdominal pain and diarrhea in the middle of the night. To take good care of your body and stay away from infectious diarrhea, we must remember the famous saying "the disease enters from the mouth". Take effective preventive measures against the above-mentioned pathogenic factors that cause infectious diarrhea, such as having fly prevention facilities for household food, tableware and fruits to eliminate cockroaches; Leftovers should be fully heated before eating; Don't eat fruits and vegetables that are suspected of deterioration; Cooked food bought outside should be reheated before eating; Don't patronize the unsanitary food stalls in the street.
