Acute gastroenteritis is a very common digestive system disease, mostly manifested as abdominal discomfort or pain, accompanied by nausea, vomiting and diarrhea, and in severe cases, fever, water loss and even shock. The main reasons for the occurrence of acute gastroenteritis include: 1. Long periods of high temperature and high humidity in summer lead to food spoilage, people eat spoiled food easily cause bacterial food poisoning, gastroenteritis; at the same time, people in the summer humid weather, easy to heatstroke, will also occur vomiting and other phenomena, so it is very important to eat fresh, clean food. 2, eat too cold food so that the stomach is too cold stimulation will also cause stomach discomfort. In this way, in the summer, to moderate the summer heat, do not greedy cold eat too many cold drinks, and the air conditioning temperature is turned on very low. Now the office or some public places have more air conditioning, if the temperature difference with the outdoors is too large, the body is difficult to adapt in a short period of time, will also cause a decline in immune function, gastrointestinal resistance to disease, and increased susceptibility to germs. 3, due to the gastrointestinal stimulation of excessive will have discomfort, such as overeating, excessive smoking, alcohol, strong tea, excessive intake of greasy and spicy food, do not pay attention to the quality of diet and diet rules. 4, excessive fatigue, improper rest or even staying up all night. 5, already suffering from chronic gastrointestinal disease, mental tension, life and diet is not regular, do not take medication on time, etc. Gastrointestinal disease is a minor disease? Do not take medicine indiscriminately if it is not a minor illness. Don’t use antidiarrheal agents in the early stages of the disease Many people who have diarrhea first want to use montelukast (such as Similac) to stop the diarrhea. In fact, this approach is incorrect. Because the excrement of diarrhea in the early stage of the disease can discharge the toxins produced by pathogenic bacteria and bacteria from the body, reducing the poisonous effects on the human body. Of course, if the diarrhea is frequent and lasts too long, and dehydration occurs, antidiarrheal agents should be used as appropriate after applying antibiotics and correcting dehydration. The children should not take any of these drugs. Norfloxacin, ciprofloxacin, levofloxacin, colistin and other drugs are also commonly used at home to treat gastrointestinal diseases. These drugs have good efficacy against intestinal pathogens. However, they are not suitable for children, pregnant women and nursing mothers and have adverse effects such as nausea, vomiting, dizziness, skin rash and leukopenia. Choose antibiotics according to the germs Many people have diarrhea accompanied by fever symptoms, so they rush to use antibiotics such as flavopiridol and haloperidol. It is not a good idea to use antibiotics when there is fever. The most common cause of intestinal infections is E. coli, E. dysenteriae, and E. deformans, so when choosing antibiotics, it is best to do a stool bacterial culture first to clarify the type of bacteria that cause the disease, and then choose the antibiotic treatment that is most sensitive to the bacteria. The actual micro-ecological preparations are used to adjust the intestinal flora and correct the dysbiosis. These drugs should not be taken at the same time as antibiotics, and constipation may occur if the dose is doubled. In addition, elderly people with glaucoma should be careful with antispasmodics such as atropine, belladonna tablets and other painkillers, which can further worsen glaucoma.
