What should I do if I have diarrhea in summer? What medicine is the most effective?

Summer is the season of high incidence of diarrhea. Many people think that diarrhea is a minor illness, but it is not. Diarrhea, if not treated in time, can sometimes lead to great disaster. Diarrhea medicine: don't take it in a hurry. Many people want to stop diarrhea as soon as they have diarrhea, thinking that as long as they don't have diarrhea, they will be fine. In fact, for infectious diarrhea, defecation is a protective mechanism of the human body. Bacteria, viruses and their toxins can be excreted from the human body through diarrhea, thus reducing the damage to the human body. Improper antidiarrheal may aggravate the symptoms of infection and poisoning. There is a more vivid saying in Chinese medicine that "close the door and keep the thief indoors", which means that if diarrhea is stopped at this time, it is equivalent to closing the door and keeping the thief indoors. When there are many watery stools but no fever, antidiarrheal drugs can be used as appropriate. When there is obvious infectious diarrhea such as bloody stool, abdominal pain and fever, antibiotics should be used and antidiarrheal drugs should be used with caution. As the saying goes, "dysentery can't last", that is, eating more diarrhea is good for dysentery, as long as you pay attention to the nature of food. If diarrhea is severe, oral or intravenous rehydration should be taken as soon as possible to prevent excessive electrolyte loss. If diarrhea is frequent and lasts for a long time, antidiarrheal drugs can be used at the same time as rehydration and antibacterial treatment. Functional diarrhea can help digestion and keep warm while using antidiarrheal drugs. However, different antidiarrheal drugs have different effects and should be used reasonably. At present, the most commonly used antidiarrheal drug is montmorillonite powder (smecta, Biqi, Kent Order). This medicine is not absorbed by itself, but attached to the intestinal wall after taking it, which can slow down the intestinal peristalsis and achieve the effect of stopping diarrhea. It is usually used for acute and chronic diarrhea caused by various reasons in adults and children. Adults take one pack (3g) orally once, dissolved in 50ml of water, three times a day. These drugs have small side effects and high safety, and their combination with antibacterial drugs is beneficial to control infection.
