Watery stools indicate bacterial or viral infections and diarrhea caused by indigestion due to cold in the stomach. If the diarrhea is more serious, with more frequent stools, watery stools and abdominal pain, it is considered to be caused by bacterial infection, so you need to go to the gastroenterology department of the hospital in time, and cooperate with the doctor to do routine stool examination and bacterial culture examination to confirm which kind of germs are causing the infection. If diarrhea occurs without abdominal pain, it is considered to be a viral infection or diarrhea caused by indigestion. You can use safranin and montelukast under the guidance of the doctor, and intravenous fluids are needed to replenish body fluids and electrolytes under the guidance of the doctor to avoid causing electrolyte disorders.
