There are many causes of diarrhea, such as a cold stomach, eating something unclean, indigestion, food allergies, and viral infections. Here are some specifics. Cold stomach. It is usually due to the fact that you don’t cover up at night, leaving your stomach exposed, and catching a cold will lead to diarrhea. Excessive coldness in the stomach and intestines can easily lead to dysfunction and sugary thin stools. This situation can be improved faster by drinking brown sugar and ginger water with boiling water. Eating something unclean. If you accidentally eat food contaminated with bacteria such as E. coli and salmonella, or drink bacteria-contaminated beverages you may experience varying degrees of abdominal pain, diarrhea and other symptoms. Especially in summer, many snack bars or restaurants have unhygienic cold dishes, which are prone to breeding bacteria and can cause diarrhea when people eat them. Indigestion. Some people eat too much greasy food, or soup, easy to cause indigestion, diarrhea. This is often referred to as “slippery bowel”. In this case, generally as long as the adjustment of the diet, eat more fruits and vegetables, eat less greasy food will slowly get better. Food allergy. If the food you eat causes allergies, it will lead to diarrhea. For example, some people drink too much pure milk, it is easy to diarrhea. So such people should drink less plain milk and try to replace it with yogurt. Viral infections. If a person gets infected with rotavirus due to improper diet or if he/she gets infected, it can easily lead to diarrhea. In this case, do not use antibiotics, which do not play much of a role, but you can drink some water with sugar and salt at home, and also take some astringent biologics and so on.
