<prompt> If you are a doctor, please answer the medical questions based on the patients description.My 3 year old son has had diarrhea for over a week. Even in his sleep. Today the diarrhea is very oily. Last night his fever was over 102. I am controlling his temp with tylenol. What could be wrong with him? He had surgery the middle of May for t and a and tubes.  <response>: Welcome to the ChatDoctorI understand your concerns but dont worry. The long-lasting diarrhea episodes with high spikes of fever and mucus in stools can be due to bacterial or amoebic gastroenteritis. So, go for a stool examination and give him a course of ofloxacin-ornidazole along with Zinc supplement such as Spy And or Zirconia and entertogermina for early relief. Hopefully it will be of help. Take care
