Some issues Dr. John Eric Demko, MD can help you with:

Acute Kidney Failure

Kidney failure is when 80% to 90% of kidney function is lost. Kidney failure is also referred to as end-stage renal disease (ESRD). Kidneys are critical to human health, essentially acting as the body's built-in filtration system. When the kidneys can no longer function effectively, waste can accumulate in the blood and concentrations of nutrients can become unbalanced, impairing the body from performing critical functions. For example, if the kidneys do not regulate levels of potassium, the heart may develop arrhythmias (irregular rhythm) or even go into cardiac arrest.

Kidney failure may be caused by a number of health conditions that slowly damage and weaken the kidneys, such as:

Diabetes
High blood pressure
Urinary tract problems
Excessive alcohol consumption
Persistent and severe dehydration
Lupus
Acute kidney injury (AKI)

High blood pressure and diabetes are the most frequently observed causes of kidney failure. However, these conditions typically take years to develop into kidney failure and might escape notice during that time.

Symptoms of kidney failure include:

Difficulty sleeping
Fatigue
Reduced appetite
Weight loss
Edema (water retention)
Ankle and foot swelling
Anemia
Itching
Muscle cramps

No cure currently exists for kidney failure; however, medical treatment can permit people to live healthy and long lives. A nephrologist (kidney doctor) determines the most effective treatments for patients with kidney failure.

Dialysis is a well-known treatment for kidney failure that uses a machine to filter and clean waste from the blood. Patients attend regular dialysis sessions to replace their lost kidney function. Some patients with kidney failure are unable to survive without having dialysis every few days.

More advanced kidney failure may be treated by kidney transplant surgery. Deceased donor kidney transplant surgery provides kidney failure patients with a healthy kidney from a recently deceased person. Living donor kidney transplant surgery provides a kidney from a donor who is still alive. As most people have two kidneys, kidney failure patients' relatives or friends may offer to donate one of their kidneys. Kidney transplants can dramatically improve kidney function and lower or eliminate the need for dialysis.

People with kidney failure are advised to eat a nutritious diet, monitor and lower blood pressure, and to best manage diabetes. Exercise and a tobacco-free lifestyle may also help patients with kidney failure.
