Nephrology focuses on diagnosing and treating kidney diseases. The kidneys filter waste, balance fluids, regulate blood pressure, and manage acute and chronic conditions.

In the world of genetic nephrology, “prevention” has a different meaning. We cannot prevent the genes we were born with, but we can prevent their worst outcomes. We practice “secondary prevention”—preventing rapid progression, preventing complications, and preventing the disease from being passed unknowingly to the next generation.
Care is about empowerment. Patients are shifting from being victims of genetics to becoming managers of their own health. It involves making informed reproductive choices, protecting the remaining kidney function with vigilance, and building a support system. This section explores how patients can take control of their genetic destiny and live well despite their diagnosis.
One of the most powerful forms of prevention is informed family planning. Knowing you carry a gene gives you choices that previous generations did not have.
For couples who want to ensure their child does not inherit the kidney disease, PGD is an option. This involves In Vitro Fertilization (IVF). Doctors create embryos in the lab and test a single cell from each for the specific genetic mutation. Only the embryos, free of the disease, are implanted in the mother. This technology allows parents to break the chain of inheritance and have a child who is genetically free of the condition.
Other couples choose to conceive naturally and test the fetus during pregnancy via chorionic villus sampling (CVS) or amniocentesis. This allows them to prepare for the child’s medical needs or make other decisions. Genetic counselors are essential guides in this deeply personal process, providing nonjudgmental support and accurate risk statistics.
Every person is born with a certain amount of kidney reserve. In genetic disease, this reserve is under attack. Prevention means guarding what is left.
Patients must become vigilant gatekeepers of what enters their bodies. Many common substances are toxic to kidneys (nephrotoxins). This includes NSAIDs (painkillers like ibuprofen), certain antibiotics, and contrast dyes used in CT scans. Patients should always inform any doctor or radiologist of their kidney condition so that safe alternatives or protective hydration protocols can be used.
Kidney stones are common in many genetic conditions and can cause scarring. Drinking enough water to keep urine diluted helps prevent the crystallization of stones. It acts as a constant internal flush, reducing the risk of obstruction and infection, which can permanently damage kidney tissue.
The heart and kidneys function together like twin engines. Protecting one protects the other. Genetic kidney patients are at higher risk for heart disease, which is actually the leading cause of death in this population.
Keeping cholesterol low prevents plaque buildup in the arteries that feed the kidneys. Statins are often prescribed not just for the heart but to ensure the kidneys receive good blood flow.
Regular, moderate aerobic exercise keeps blood vessels flexible and lowers blood pressure. It helps manage weight and sugar levels. For patients with genetic conditions, exercise is a prescription, not just a hobby. It builds a physiological buffer against the stress of chronic disease.
A genetic diagnosis can bring guilt (“Did I give this to my child?”) or anxiety about the future. Emotional care is part of physical care.
Rare diseases can feel lonely. Connecting with patient advocacy groups (like the PKD Foundation or Alport Syndrome Foundation) provides a community of people who “get it.” These groups offer practical tips on diet, insurance, and coping strategies that doctors might not know.
Stress raises blood pressure, which hurts kidneys. Mental health support, whether through therapy, meditation, or support groups, is a biological necessity. Reducing cortisol (stress hormone) levels helps protect the organs.
Patients can actively participate in the future of their disease by joining patient registries.
These databases collect anonymous data on symptoms and progression from thousands of patients. Researchers use this “big data” to find patterns and develop new drugs. By joining a registry or a clinical trial, patients contribute to finding the next breakthrough. It is a way of fighting back against the disease not just for oneself, but for the entire community.

Only if you have been genetically tested and cleared. If you have the same gene, donating could be dangerous for you and the recipient.
Yes, PGD has been used for decades. The biopsy of the embryo is done at a very early stage and does not increase the risk of birth defects.
Yes. Because it is genetic, your siblings, cousins, and parents might be at risk. Sharing your diagnosis allows them to get tested and protected early.
You cannot stop them completely yet, but drugs like tolvaptan, combined with high water intake and low salt, can significantly slow their growth.
