The doctor reminded that it is not necessary to drink boiled water blindly to replenish water. It is best to drink electrolyte aqueous solution containing appropriate salt and water. If you drink boiled water desperately, it may lead to insufficient electrolytes in the body and cause cramps. The rehydration salts that can be bought in pharmacies can also be bought back and taken by yourself. Acute gastroenteritis is the most common disease after summer. Once bacteria and viruses invade the stomach, it often leads to vomiting, diarrhea and abdominal pain, which is very uncomfortable. When you see a gastroenterologist, the doctor usually suggests fasting for half a day or a day and replenishing more water. Summer is approaching. Every summer, except respiratory tract infection, acute gastroenteritis is the most common. Pathogens include salmonella or adenovirus, enterovirus, etc. Patients will have symptoms such as vomiting and diarrhea, abdominal pain, fever, and even severe abdominal spasmodic pain, high fever and chills, anorexia and burnout. Generally speaking, it takes about three to seven days to treat acute gastroenteritis. In addition to taking medicine and fasting for 12 to 24 hours, patients may be dehydrated because they keep pulling, so they must be replenished with enough water during fasting. It is worth noting that in addition to losing water, children also lose electrolytes when vomiting and diarrhea, so it is best to supplement the "rehydration salt" sold by pharmacies instead of pure boiled water. Some parents just give their children boiled water blindly, but as a result, they dilute the electrolyte in the body, causing cramps and other "water poisoning". Although sports drinks on the market also contain salt, the sugar in the drinks is also high, which will make children with diarrhea continue to have diarrhea. As for the "rehydration salt", it contains a proper amount of sugar and salt, which can not only supplement the water and salt lost by vomiting and diarrhea, but also avoid persistent diarrhea due to high sugar. In addition, patients with acute gastroenteritis lose appetite during recovery and can eat some light and digestible food. Children can eat porridge, pasta, soda biscuits, apples, bananas and so on. As for children under one year old, infants who take infant formula as their staple food can dilute the milk powder or switch to a special formula without lactose, and then return the milk powder to its original concentration after the symptoms improve. Tips: Normal people should consume about 2 liters of water every day, and it is best to drink warm boiled water, but it should be supplemented several times, and the amount of water to drink each time should be about 200-300ml. It is best to have a drink after getting up in the morning to promote gastrointestinal peristalsis and facilitate defecation. Try to drink less ice water and cold water, and it is best not to drink a lot of water half an hour before and after meals, so as not to dilute gastric juice, dilute gastric acid and damage digestive function.
