Viral diarrhea is generally more serious when compared to bacterial diarrhea. This is because bacterial diarrhea has a more rapid onset than most viral diarrhea, and the symptoms are more severe, such as diarrhea, vomiting, etc., and it is easier to develop dehydration or electrolyte disorders. 1. Viral diarrhea is mostly caused by rotavirus infection, which can cause diarrhea, watery stools, abdominal pain, bloating and other symptoms. If the symptoms are mild, you can follow the doctor’s instructions to replenish fluids and maintain electrolyte balance, and most of them will recover by themselves. 2. Bacterial diarrhea is mostly caused by bacterial infections, which may cause diarrhea, nausea, vomiting, loss of appetite, abdominal distension and other symptoms. It is necessary to take oral antibacterial medication, such as norfloxacin, as prescribed by the doctor. 3. Because bacterial diarrhea has serious symptoms, the probability of dehydration and electrolyte disorders is higher, and anti-infective drugs are needed to relieve it; viral diarrhea can be relieved on its own by replenishing fluids to prevent dehydration. Therefore, bacterial diarrhea is relatively more serious. If you have diarrhea or uncomfortable symptoms, you need to consult a doctor for examination to determine the cause of the disease and then follow the doctor’s instructions for symptomatic treatment.
