My 88 year old husband has just been diagnosed with impaired kidney function (raised creatinine level on blood/urine testing). He has been advised that he needs a referral to a Nephrologist but there is a delay in this happening. In the meantime, he is suffering attacks of diarrhea on most days. I am currently modifying his diet in line with the advice on your website but, in the meantime, would you consider his diarrhea is related to his kidney impairment or should we seek urgent advice regarding this? He is losing weight, muscle, tone and strength too. Multiple myeloma has been ruled out by the Oncologists. Many thanks, in advance, for any advice you can give me whilst waiting for his referral.

Diarrhea is sometimes seen in late stage chronic kidney disease (CKD), but it not a typical finding in earlier stage chronic kidney disease.  Diarrhea can lead to dehydration which can make CKD worse and may lead to acute kidney injury superimposed on CKD.  If there is ongoing diarrhea, replacement with a sports drink and continued hydration will be important.  I would suggest that you consult with your husband’s primary care physician (PCP) about evaluation and treatment of the diarrhea.
