Living with one kidney may seem daunting at first, but most people live full, healthy lives with a solitary kidney. Whether due to congenital conditions, surgery, or kidney donation, a single functioning kidney can still support your overall well-being. In this blog, we will explore the causes of having one kidney, the potential complications, and ways to maintain optimal health, while also touching on conditions like kidney transplant, high blood pressure, and chronic kidney disease.
Understanding the Causes
There are several reasons a person might have just one functioning kidney:
- Renal Agenesis: This is a condition in which a person is born with just one kidney.
- Kidney Dysplasia: A person may be born with two kidneys, but one doesn’t function properly.
- Surgery: Kidney removal due to injury or conditions like cancer can result in having a solitary kidney.
- Transplant Donor: Kidney transplant programs are very careful to only take kidneys from people whose remaining kidney is healthy and expected to support them for their entire life.
Most people with a single kidney, regardless of the cause, lead normal, healthy lives. However, they must be cautious and proactive about protecting their kidney health.
Common Complications and Health Risks
While many people with one kidney face few health problems, there are certain risks to be aware of:
- High Blood Pressure: One of the more common issues faced by individuals with a single kidney is an increased risk of high blood pressure. Your kidneys play a vital role in regulating blood pressure, so it is important to monitor it regularly.
- Protein in the Urine (Albuminuria): Over time, some individuals may develop protein in their urine, which can be a sign of kidney stress or damage.
- Chronic Kidney Disease (CKD): Although rare, there is a possibility that over time, the remaining kidney might lose some function, potentially leading to chronic kidney disease. It is important to have your kidney function checked annually to ensure early detection and management of any decline.
Despite these risks, most people with one kidney live long, healthy lives. With proper care and regular medical check-ups, complications can be managed or prevented.
Diagnosis and Testing
Many people who are born with one kidney may never experience symptoms and might only discover their condition during routine imaging tests, such as CT-scan or ultrasounds. However, regular kidney function tests are crucial, especially if you are aware of your solitary kidney. Healthcare professionals typically perform two primary tests:
- Estimated Glomerular Filtration Rate (eGFR): This blood test measures how well your kidneys are filtering waste from your blood.
- Urinary Albumin-to-Creatinine Ratio (uACR): This urine test checks for albumin, a protein that can indicate kidney damage.
If you do not currently have hypertension, it is important to check your blood pressure at least once a year, as it is directly linked to kidney health.
Managing and Protecting Your Kidney
If you have one functioning kidney, taking proactive steps to protect its health is essential. Here are some practical tips to keep your kidney functioning well:
- Manage Blood Pressure: Since high blood pressure can damage your kidney, it is important to monitor and control it through a healthy lifestyle and, if necessary, medication.
- Maintain Healthy Blood Sugar Levels: If you have diabetes or are at risk, controlling your blood sugar is key to protecting your kidney.
- Reduce Salt Intake: Avoiding a high salt diet may help prevent high blood pressure.
- Avoid NSAIDs: Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen can harm your kidney over time. Speak to your healthcare provider before using any over-the-counter medications.
- Exercise Regularly: Regular physical activity can help maintain a healthy weight and improve heart health, both of which benefit your kidney.
Medications and Kidney Transplants
If you have one healthy kidney and no underlying kidney disease, you likely won’t need medications specific to kidney health. However, individuals who have received a kidney transplant must take immunosuppressive medications to prevent the body from rejecting the transplanted organ. Additionally, those with kidney disease may be prescribed medications such as ACE inhibitors, ARBs, or diuretics to manage chronic kidney disease and reduce the progression of kidney damage.
Nutrition and One Kidney
For the majority of individuals with a healthy single kidney, no specific diet is necessary. However, eating a balanced diet rich in fruits, vegetables, and minimally processed foods is important for overall health. Individuals with a kidney transplant or those at risk for chronic kidney disease may need to adjust their diet to manage high blood pressure, diabetes, or other conditions that affect kidney function. Consulting with a healthcare provider or dietitian can ensure you make the best nutritional choices for your specific situation.
Exercise Considerations
Physical activity is highly recommended for maintaining overall health. However, if you have one kidney, it is crucial to protect it from injury. While most activities are safe, you might need to avoid contact sports such as football, soccer, and martial arts, which pose a higher risk of trauma to the kidney. Most sports do not have protective gear that protects the kidneys. Perhaps martial arts do.
For general physical health, the Centers for Disease Control and Prevention (CDC) recommends 150 minutes of moderate-intensity activity per week. This can range from walking and gardening to dancing and doing household chores. The important thing is to find activities you enjoy and can easily fit into your daily routine.
Emotional and Psychological Support
Living with one kidney may bring emotional and psychological challenges, especially if you’ve had a kidney transplant or are managing chronic kidney disease. It is important to reach out for support from healthcare professionals, family, and friends. Many find it helpful to connect with support groups or kidney health organizations that provide resources, education, and community for individuals living with kidney-related health conditions.
Living with one kidney does not mean you have to sacrifice your quality of life. With regular medical check-ups, a healthy lifestyle, and an understanding of your kidney’s needs, you can lead a fulfilling and active life. Whether you were born with one kidney, lost a kidney due to surgery, or donated one as part of a kidney transplant, there are many ways to maintain your health and thrive. Taking care of your kidney today can ensure a healthy future tomorrow.
