<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, my 18 month old son has had pale lose poo for several days now. He s also very tired and has been sleeping for around 3 hours extra a day. He could just be overtired with Xmas etc but the colour of his makes me slightly nervous. Any suggestions?  <response>: Welcome to the ChatDoctorI completely understand your concerns. Pale loose stools and lethargy is not a normal finding in toddlers. It can be due to liver dysfunction or gut infections. I see such cases in my clinical practice and recommend them for the following measures:1. Proper stool examination- routine, microscopy and ovacyst detection.2. A complete blood count with peripheral smear and liver function test to check for associated jaundice.3. In case of conjugated hyperbilirubinemia, an ultrasound abdomen might be helpful.4. Keep the child well HY Chat Doctor.
