[|Human|] my 20 year old son has orange/red urine and stool, no appatite for two days, when ate vomited. He takes lithium for bipolor, and had high creatine levels almost two months ago and was told kidneys were shutting down, and then got better.  Just moved to another state and doesnt have doctor yet. He doesnt want to go to emergency because of cost, so a doctors office during business hours would be best.  Worried mom here, what can he do?
[|AI|]  Hi, Welcome to Chat Doctor forum.  There are so many causes of the orange colored urine and stools, with vomiting in 20 years old.  The commonest may be the hepatitis, urinary tract infection, stone in the ureter, or kidney infection etc. I advise you to consult a gastroenterologist for diagnosis and treatment.  He may need to have ultrasound, besides other blood tests for confirmation.  Wishing for a quick and complete recovery. Thank you.
