Generally, patients with mild diarrhea can take a normal bath, but they need to pay attention to adjusting the bathroom temperature and water temperature, and wrap a bath towel and dry their bodies in time after bathing. However, if the diarrhea is more obvious, it is recommended not to get up and take a bath first, pay attention to keeping warm, rest in bed, and seek medical treatment promptly. The common causes of diarrhea are related to abdominal cold, unclean diet, indigestion and intestinal infection. After diarrhea occurs, the patient’s body will feel uncomfortable, so a hot bath can reduce local spasm and increase blood circulation to relax the body and relieve the discomfort caused by diarrhea. However, for patients with severe diarrhea, as the patients themselves are in a relatively weak state on weekdays, if they take a bath at this time without paying attention to warmth or bathing for too long, it may lead to excessive fatigue and even fainting, which will have a great impact on their health. After diarrhea occurs, it is recommended to take simple care at home, such as keeping warm, drinking warm water and paying attention to dietary hygiene. If the diarrhea is not relieved or worsened, patients should go to the gastroenterology department and undergo examinations as prescribed by the doctor to determine the cause of the disease and provide symptomatic treatment to promote recovery.
