Kidney function and failure

The kidneys filter waste, balance electrolytes, regulate blood pressure, and produce hormones that support red blood cell production and bone health. When kidneys fail, waste products and fluid accumulate, causing symptoms such as fatigue, swelling, shortness of breath, and changes in urination. Causes include diabetes, high blood pressure, chronic glomerulonephritis, and inherited conditions. Assessments typically include blood tests (creatinine, eGFR), urine tests, imaging, and sometimes biopsy to determine the extent and cause of damage.

Managing underlying causes early — for example, controlling blood sugar and blood pressure — is essential to slow decline. Lifestyle changes (dietary adjustments, fluid management, reduced sodium intake), medication reviews, and avoidance of nephrotoxic agents (certain pain relievers, contrast dyes) are standard medical steps before kidney replacement becomes necessary.

Health risks and symptoms

Progressive kidney impairment increases risks such as fluid overload, electrolyte imbalances (notably high potassium), anemia, bone mineral disorders, and cardiovascular disease. Symptoms vary by stage but can include persistent fatigue, nausea, itching, confusion, and edema. Monitoring with regular clinic visits and lab tests helps detect complications earlier and guide treatment adjustments to reduce risks to heart and other organs.

Patients often work with a multidisciplinary team — including dietitians, nurses, social workers, and pharmacists — to manage nutrition, medication adherence, and symptom control. Vaccinations and infection prevention are also important because people with kidney failure have altered immunity and higher susceptibility to infections.

Medical treatments available

Medical management focuses on treating reversible causes, slowing progression, and managing complications. Common medical therapies include blood pressure control (often with ACE inhibitors or ARBs), glucose control for diabetes, diuretics to manage fluid, medications to treat anemia (erythropoiesis-stimulating agents and iron), phosphate binders for mineral balance, and adjustments to other prescriptions that affect kidney function.

When conservative measures no longer maintain adequate kidney function, kidney replacement therapy becomes necessary. Options include various forms of dialysis and kidney transplantation. Choice of therapy depends on clinical factors, lifestyle considerations, and availability of services in your area.

Role of your doctor in care

A primary care doctor often identifies early decline through routine labs and coordinates referrals to nephrology (kidney specialists) when needed. Nephrologists evaluate disease stage, discuss treatment options, and manage complex medical therapies. Communication between your doctor, specialists, and allied health professionals ensures medication safety, timely interventions, and appropriate preparation for dialysis or transplant when indicated.

Shared decision-making is central: your doctor should explain risks and benefits of different approaches, assess suitability for transplant, and help plan logistics such as vascular access creation for dialysis or identifying transplant evaluation centers in your area.

Hospital-based dialysis and transplant options

Hospitals and specialized clinics provide in-center hemodialysis, which uses a machine to filter blood several times per week, and inpatient care for acute kidney injury requiring short-term dialysis. Peritoneal dialysis, often managed at home after training, uses the abdominal lining to filter waste and can be a flexible alternative for some patients. Transplantation offers the possibility of restored kidney function but requires evaluation, matching, and lifelong immunosuppression.

Surgical procedures (fistula creation for hemodialysis access or transplant surgery) and inpatient monitoring are typically performed in hospital settings with multidisciplinary teams. Post-procedure follow-up includes surveillance for rejection, infection, and medication-related side effects.

Care coordination and lifestyle considerations

Effective long-term management combines medical treatment with lifestyle measures. Nutritional counseling can tailor protein, potassium, phosphorus, and fluid intake to the stage of kidney disease. Smoking cessation, regular but appropriate physical activity, and weight management support overall health. Mental health support and social services help address the emotional and practical challenges of chronic illness, such as transportation to treatments and medication costs.

Advance care planning and clear discussions about goals of care are important for people with advanced kidney disease so that treatment choices align with personal values and expected outcomes.

Conclusion

Kidney failure treatment spans prevention, medical management, dialysis modalities, and transplantation, delivered by a team that includes your doctor, nephrologists, hospital staff, and allied health professionals. Early identification and targeted interventions can slow progression and reduce complications, while choices about replacement therapy should consider clinical needs, lifestyle, and access to local services. Continuous monitoring and coordinated care improve symptom control and quality of life for people living with kidney disease.
