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

When discussing prevention in the context of hemodialysis, we are looking at two different phases. First, there is the prevention of kidney failure itself—trying to stop the progression of the disease so dialysis is never needed. Second, for those already on dialysis, prevention means avoiding complications like infections, clotting, and heart disease. Care involves a proactive approach to daily living, empowering patients to be the managers of their health rather than passive recipients of treatment.
This section covers how to protect the kidneys you have left, how to keep your dialysis access healthy, and the critical importance of mental health and support systems in navigating this chronic journey.
For those with early-stage kidney disease, the goal is to delay dialysis as long as possible. The two most powerful tools are blood pressure control and blood sugar management.
Keeping blood pressure below 130/80 minimizes the pounding damage to the kidney filters. This often involves taking ACE inhibitors or ARBs, medicines that specifically protect the kidneys. For diabetics, keeping the A1C (average blood sugar) healthy prevents the sugary blood from destroying the nephrons. Avoiding “nephrotoxins” is also vital. This includes NSAIDs like ibuprofen (Advil/Motrin), which can shut down blood flow to the kidneys. Using Tylenol instead is a simple, kidney-saving swap.
For patients on dialysis, infection is the second leading cause of death after heart disease. The access site is a direct doorway into the bloodstream. Germs on the skin can travel down the needle or catheter and cause sepsis (blood infection).
Patients must wash their access arm with antibacterial soap before every treatment. They should avoid coughing or sneezing near the exposed site. Nurses and technicians must wear masks and gloves. If a patient has a central venous catheter (a tube in the chest), it must never be submerged in water (no swimming or baths), and the dressing must be kept dry and clean.
Heart disease is the biggest threat to dialysis patients. The stress of fluid shifts and the calcification of arteries make the heart vulnerable. Prevention involves managing the “fluid gains.”
Gaining too much fluid weight between treatments (more than 2-3 kg) forces the machine to pull it off aggressively. This drops blood pressure rapidly, which can “stun” the heart muscle and cause long-term damage. Sticking to the fluid restriction is actually a heart-protection strategy. Exercise is also encouraged. Low-impact activities like walking or stationary biking help keep blood vessels flexible and improve stamina.
The fistula is often called the patient’s “lifeline.” Losing a fistula means surgery and temporary catheters, which carry risks.
Patients should check the “thrill” (vibration) every morning. They should listen for the “bruit” (whooshing sound) if they have a stethoscope. Any change—like the vibration disappearing or the arm becoming red and hot—requires an immediate call to the center.
The fistula arm should be treated like royalty. No heavy lifting that could strain the vessel. No tight clothing or watches that could restrict flow. No blood draws or blood pressure cuffs on that arm ever. Sleeping on the arm should be avoided to prevent compressing the flow.
Living on dialysis is mentally taxing. Depression and anxiety are common. Burnout can result from feeling dependent on a machine.
Acknowledging this burden is the first step in care. Support groups, either in-person or online, connect patients with others who “get it.” Engaging with a renal social worker can provide access to counseling or transportation assistance. Taking an active role—like holding your own needle sites or learning to set up the machine—can restore a sense of control and agency, which is a powerful antidote to depression.
For many, the ultimate “prevention” of long-term dialysis complications is a kidney transplant. Getting on the transplant list is a rigorous process involving heart tests, cancer screenings, and dental clearance.
Patients should stay “transplant ready.” This means keeping vaccinations up to date, maintaining a healthy weight, and not smoking. Finding a living donor is the fastest route. Patients are encouraged to share their story; often, friends or extended family are willing to donate but don’t know the need exists. A transplant offers freedom from the machine and a return to a more normal diet and lifestyle.

Exercise doesn’t make you pee more if your kidneys have failed, but it helps you sweat out a little fluid and keeps your heart strong.
Yes, and it is highly recommended. Dialysis patients have weaker immune systems, so preventing the flu and pneumonia with vaccines is critical care.
Yes, keeping the skin moisturized prevents cracking and infection. However, do not apply cream right before dialysis, as it makes the skin slippery and difficult to clean for needle insertion.
Home machines have battery backups or manual cranks to return your blood safely. You are trained on exactly how to disconnect in an emergency during your training weeks.
Yes. You are given blood thinners (heparin) during treatment, so dental work should be done on non-dialysis days to prevent bleeding issues. They also need to know to prescribe kidney-safe antibiotics if needed.
