Understanding Chronic Kidney Disease in cats
What is Chronic Kidney Disease?
Chronic kidney disease (CKD) is defined as a structural or functional abnormality of one or both kidneys, lasting for 3 months or more. It is characterised by a permanent, irreversible and progressive reduction in the number of functional nephrons, leading to compromised filtration, impaired electrolyte balance, and the accumulation of waste products.
CKD vs. AKI (Acute Kidney Injury)
Distinguishing between CKD and acute kidney injury (AKI) is essential. CKD is irreversible, cumulative damage, while AKI is sudden and often reversible. Recognising these differences guides appropriate care.
How common is CKD in cats?
CKD is common in older cats, constituting a substantial portion of veterinary kidney cases. Understanding the prevalence and risk factors helps in managing this condition.
Exploring Causes and Risk Factors
While ageing is a primary contributor, factors like genetics, infections, and exposure to nephrotoxic agents can contribute. Identifying and addressing these factors is crucial for effective treatment. Unfortunately, the causes of CKD are often not present at the time of diagnosis.
The Normal Role of the Kidneys
Healthy kidneys filter waste, regulate electrolytes, and maintain overall homeostasis. As CKD progresses, these functions are compromised, requiring strategic dietary and therapeutic interventions.
Why is early detection of CKD so crucial for my cat?
Beyond the importance of tests for diagnosing CKD, it is even more important to know the early signs of CKD. Early diagnosis is crucial to effective management, as its impact shapes the trajectory of the disease.
Regular veterinary visits are a crucial element of feline health care, especially as cats age. These visits provide the opportunity for comprehensive check-ups, including general laboratory tests and appropriate diagnostic tools, which identify subtle markers of early kidney disease and are the first line of detection for CKD.
This proactive approach enables interventions before clinical signs become overt.
Recognising Common Signs of CKD in cats
Be vigilant for subtle signs like increased thirst, changes in urine habits, dirtier or wetter than normal litter box, weight loss, and altered urine concentration. Regular veterinary visits enhance early detection.
