Chronic Kidney Disease (CKD): Why Essential Questions Often Go Unanswered

Recently, a patient with stage 4 Chronic Kidney Disease (CKD) posed an intriguing question that shed light on a significant gap in healthcare practices. He asked, "Doctor, I've consulted numerous doctors over the years due to my high blood pressure. Yet, none of them ever recommended a kidney function test. Why?"

This question isn't just a personal query—it's a reflection of a widespread issue in medical practice that affects countless individuals. Today, we'll explore some fundamental questions that often arise in the minds of patients diagnosed with chronic kidney disease, particularly why these questions aren't always raised by healthcare providers or addressed early enough to prevent the progression of the disease.

The Unasked Questions: Why Aren’t Doctors Checking Kidney Function?

In my experience as a nephrologist, I've encountered many patients who, after being diagnosed with CKD, wonder why their kidney function wasn't monitored sooner. One would expect that, given the correlation between high blood pressure and kidney disease, a basic kidney function test would be a routine recommendation. Yet, many patients report that this critical test was never suggested.

This isn't just an isolated issue. Many patients feel that their healthcare providers failed to address the potential for chronic conditions like kidney disease early on, leading to delayed diagnoses and, consequently, a lack of timely treatment options.

The Basic Yet Overlooked Tests

Consider this scenario: a patient visits multiple doctors over the course of several years, each time being treated for high blood pressure. Despite this, none of these healthcare professionals recommend a renal function test, which could easily have been included in the basic screening process. Why is this the case?

The truth is, I don’t have a definitive answer. It’s disheartening to see patients who have had multiple interactions with the healthcare system, yet critical tests such as Renal Function Tests (RFTs) were never conducted. It raises the question of why basic medical knowledge isn't applied uniformly across all cases, particularly when dealing with high-risk patients.

The Role of Pharmacists and General Practitioners

Pharmacists and general practitioners play a crucial role in patient care. However, it’s concerning that even when dispensing medication or checking blood pressure, there is often no suggestion to perform a kidney function test. This lack of recommendation is alarming, especially considering the simplicity and importance of such tests in detecting early signs of kidney disease.

In essence, there is no straightforward answer to why healthcare providers often overlook these essential tests. Whether you are a completely healthy individual or someone with high blood pressure or diabetes, regular monitoring of kidney function should be a priority.

The Complexity of Proteinuria Testing

Another perplexing issue is the lack of routine testing for proteinuria (the presence of protein in urine), which is often an early indicator of kidney damage. Medical students learn as early as their third year that patients with risk factors for kidney disease, such as diabetes, hypertension, or a family history of renal problems, should be screened for proteinuria. Yet, many doctors fail to conduct this simple test, which could provide vital information about a patient’s kidney health.

Proteinuria is often the first sign of kidney disease. Without detecting it early, comprehensive screening for kidney disease remains incomplete. In Pakistan, even nephrologists sometimes overlook this critical step, neither testing for proteinuria nor quantifying it, which can delay necessary treatment.

Asking the Right Questions

It’s essential to start asking your doctor the right questions. If you’re seeing a healthcare provider, especially for conditions like high blood pressure or diabetes, ask them directly about kidney function tests and proteinuria screening. This can be done respectfully, without confrontation, but it’s crucial to advocate for your health.

Why is Proteinuria Testing Neglected?

While the reasons for neglecting proteinuria testing remain unclear, it could be a matter of cost-saving or simply an oversight. However, the consequences are far more severe than the savings. The test itself is inexpensive and straightforward, yet it can provide early indications of kidney disease that, if left unchecked, could lead to more significant health issues.

The Importance of Kidney-Protective Medications

Another critical question often unasked is why certain patients aren’t prescribed kidney-protective medications, especially when their condition warrants it. In previous discussions, I've delved into the cultural and systemic pressures that influence doctors' prescribing habits.

For instance, kidney-protective medications can initially cause a rise in creatinine levels, which can alarm patients who associate rising creatinine with worsening kidney function. Doctors often find it challenging to explain this paradox and may opt to prescribe less controversial medications, even if it means compromising long-term kidney health.

This approach might prevent immediate concern, but it also leaves the underlying kidney disease to progress unchecked. The reluctance to prescribe these medications is a complex issue, often driven by a combination of patient expectations and doctors’ desire to avoid difficult conversations.

If you're not on kidney-protective medications despite having a condition that warrants them, it's essential to have an open discussion with your nephrologist. Understanding why these medications are not prescribed could provide insight into your treatment plan and ensure you're receiving the best possible care.

The Referral to a Specialist: Why the Delay?

A common frustration among patients is the delay in being referred to a kidney specialist. Often, general practitioners continue to manage conditions like CKD, despite the complexity requiring specialist care. This is particularly concerning in countries like Pakistan, where the concept of referring patients to specialists isn’t as ingrained in the healthcare system as it should be.

Doctors might hesitate to refer patients for various reasons, including the desire to retain patients in their practice or a lack of awareness about the severity of the patient’s condition. Unfortunately, this often results in patients not receiving the specialized care they need until it’s too late.

If you suspect that your condition requires specialist attention, it’s crucial to advocate for yourself. Don’t hesitate to request a referral to a nephrologist or another relevant specialist. Your health is too important to wait for a doctor’s recommendation if you believe you need more focused care.

The Lack of Lifestyle Recommendations

Lastly, one of the most significant missed opportunities in patient care is the failure to recommend lifestyle changes. Many patients continue taking medication for years, even progressing to insulin for diabetes, without ever being advised on how lifestyle modifications could potentially reduce their need for medication or even improve their condition.

By the time these patients visit a specialist, they’re often surprised to learn that with some lifestyle adjustments, their health could have been better managed, possibly preventing the progression of their disease. It’s essential to discuss lifestyle changes with your healthcare provider proactively, rather than waiting for the situation to worsen.

Conclusion: Taking Control of Your Health

The healthcare system is complex, and it’s not always easy to navigate. However, as patients, it’s crucial to take an active role in our health management. Asking the right questions and demanding the necessary tests and treatments can make a significant difference in outcomes, especially for chronic conditions like CKD.

Remember, your doctor is your partner in health, but it’s up to you to ensure that all aspects of your care are being addressed. Don’t be afraid to question, clarify, and advocate for the best possible care. Your health is worth it.
