Chronic kidney disease (CKD) continues to be a significant public health issue worldwide, with an estimated 35.5 million Americans affected, as reported by the National Institutes of Health. Alarmingly, many individuals remain unaware of their condition. Kidney health, experts say, should be a lifelong focus, starting as early as childhood.
Dr. Wei Ling Lau, a nephrologist at UCI Health, emphasizes the importance of preventive measures in childhood to reduce the risk of kidney-related complications later in life. She explains that many adults diagnosed with kidney disease had early risk factors, such as being overweight or having poor eating habits, which set the stage for conditions like diabetes and high blood pressure—two of the primary causes of kidney disease.
“The key to preventing kidney disease lies in addressing risk factors early,” says Dr. Lau. “Maintaining a healthy weight and making healthier lifestyle choices can significantly reduce the chances of developing these conditions.”
The Vital Functions of Kidneys
Healthy kidneys are crucial to overall well-being. In addition to filtering waste from the blood, kidneys play several essential roles, including:
- Regulating blood pressure
- Balancing bodily fluids
- Controlling body chemistry and red blood cell production
- Supporting bone health
Dr. Lau emphasizes the importance of keeping kidneys functioning at their best to maintain overall health.
Maintaining Kidney Health
According to Dr. Lau, monitoring key health metrics—such as blood pressure, blood sugar, and cholesterol—is vital in preserving kidney function. Maintaining these levels can be achieved through healthy lifestyle choices such as:
- Reducing salt intake
- Choosing heart-healthy foods
- Limiting alcohol consumption
- Engaging in regular physical activity
- Achieving and maintaining a healthy weight
- Quitting or avoiding smoking
Regular medical check-ups and lab tests are also crucial. A simple urinalysis and comprehensive metabolic panel can help detect early signs of kidney dysfunction, enabling doctors to intervene early.
The Importance of Hydration
Hydration plays a critical role in kidney health. Dr. Lau recommends drinking between 60 and 70 ounces of water daily to ensure proper hydration and support kidney function.
Understanding Urine and Kidney Health
Urine color can offer clues about hydration and kidney health. Dr. Ralph Clayman, a urologist at UCI Health, explains that clear to yellow urine is typically a sign of proper hydration. However, urine that is brown despite adequate water intake could signal a potential kidney issue, particularly if accompanied by swelling, reduced urination, or fatigue.
Urine that appears pink or reddish—especially if not caused by foods like beets—should be taken seriously. This discoloration often indicates the presence of red blood cells, which can be a sign of infection, kidney stones, or even cancer. If you experience this, it’s important to seek medical advice immediately.
“Pink or red urine is a literal and figurative red flag,” says Dr. Clayman. “Don’t ignore it—contact your doctor for an evaluation.”
Maintaining kidney health is a lifelong effort that requires attention to lifestyle choices, regular check-ups, and proper hydration. Taking steps early can significantly reduce the risk of kidney disease and improve overall health.
