Patients with poor health and poor gastrointestinal function are prone to diarrhea symptoms when they are fed antibiotics because the antibiotics cause an imbalance in the intestinal flora. There are many flora in the human intestine and these flora are in a balanced state, while such drugs as antibiotics enter the human body and will hunt and kill various bacteria, at this time it is easy to have an imbalance of flora in the body and thus diarrhea. When diarrhea occurs after an infusion, it is important to promptly communicate with the attending physician, and care needs to be taken to temporarily stop the antibiotic infusion. Try to eat a liquid or semi-liquid diet that is easy to digest, and pay attention to drink more water to avoid water and electrolyte disorders.
