Drinking hot water in patients with gastroenteritis may not help relieve the symptoms of abdominal pain, diarrhea and vomiting. This is because gastroenteritis is more or less dehydrated to varying degrees, and drinking hot water can be a good way to replenish the body’s water loss, which means that it can have a rehydrating effect, and can relieve the symptoms of dizziness, weakness, and loss of appetite that occur when patients are dehydrated. In general, it is beneficial for patients with gastroenteritis to drink hot water. If there is obvious abdominal pain, diarrhea, vomiting and other symptoms, it is recommended to give medication, preferably acid suppressants combined with probiotics, acid suppressants can relieve the symptoms of abdominal pain, nausea, vomiting, and probiotics can be used to treat diarrhea. If it is a serious gastroenteritis patient, you need to go to the hospital in time.
