What should I do if I have diarrhea at both ends in three days?

It is not normal to have diarrhea at both ends for three days. First of all, you should pay attention to food hygiene and don't eat too spicy. If there is no such situation, you should go to a professional hospital for examination and seek the help of a doctor to see if there are other lesions in the stomach. Only in this way can problems be found in time and solved in a symptomatic way.
