Iatrogenic is defined as a health condition or adverse effect that is caused directly by medical examination or treatment. The term literally translates to "physician-produced." In the world of Chronic Kidney Disease (CKD) management, this is a constant risk because the treatment regimen is complex and involves a delicate balancing act.
The most common iatrogenic complication in CKD cats is fluid overload. This occurs when a caregiver administers too much subcutaneous fluid, overwhelming the cat's cardiovascular system. The compromised kidneys cannot excrete the water fast enough, and the excess fluid backs up into the lungs (pulmonary edema) or the chest cavity (pleural effusion), effectively drowning the cat from the inside. Other examples include Hypophosphatemia caused by excessive phosphate binders or Acute Kidney Injury triggered by prescribing NSAIDs (painkillers) to a dehydrated renal patient. Preventing these issues requires a philosophy of "start low and go slow," frequent blood work monitoring, and strictly tailoring fluid doses to the cat's current weight and heart health rather than using a generic dosage.
