Kidney disease is a serious condition that affects millions of people around the world. It occurs when the kidneys become damaged and can no longer function as they should. These organs are essential for maintaining the body’s balance of fluids and electrolytes, filtering waste from the blood, regulating blood pressure, and supporting red blood cell production.
Because kidney disease often develops silently, early detection is crucial. Fortunately, the body does give warning signs when something is wrong. Recognizing these symptoms can help you seek medical care before the condition becomes severe.
Understanding the Kidneys' Role
The kidneys are two bean-shaped organs located on each side of the spine, just below the ribcage. When healthy, they filter roughly 120–150 quarts of blood each day and generate 1–2 quarts of urine. They regulate fluid levels, remove toxins, balance minerals such as sodium, potassium, and calcium, and help manage blood pressure and red blood cell production.
What Is Kidney Disease?
Kidney disease, or renal disease, occurs when the kidneys are damaged and unable to work effectively. Common causes include:
-
-
High blood pressure
-
-
-
Diabetes

If left untreated, kidney disease can progress to kidney failure, which may require dialysis or a transplant. Early recognition and treatment can slow or even prevent serious complications.
