15 Deadly Kidney Disease Symptoms You Need to Detect Early
One of the kidneys' main functions is fluid balance. When the kidneys stop functioning properly, excess fluid has nowhere to drain and accumulates in the tissues.
This causes swelling, also known as edema, which is most noticeable in the ankles, feet, and hands. Over time, the swelling can become more severe and uncomfortable, signaling the need to consult a doctor.
Blood in the urine
Healthy kidneys maintain blood cells in the body while filtering waste products. Blood leaking into the urine can be a warning sign of serious problems, such as infection, kidney stones, or even cancer.
If you notice pink, red, or cola-colored urine, never ignore it. This symptom always requires medical attention.
Foamy or bubbling urine
Occasional bubbles in the urine may be harmless, but persistently foamy urine is cause for concern. This usually indicates protein leakage into the urine—a classic sign of kidney damage.
Protein needs to remain in the blood to support muscles, repair tissue, and maintain normal body functions. Protein loss in the urine indicates kidney problems.
Frequent or decreased urination
Kidney disease can cause two opposing problems: urinating too often, especially at night, or urinating much less than usual.
Both conditions suggest that the kidneys are not regulating fluids properly. Frequent urination may also be associated with infections, and reduced urine output signals advanced kidney failure.
Pain in the lower back or side
Kidney pain typically presents as a sharp or dull ache on one side of the back, just below the rib cage. This discomfort can be caused by kidney stones, an infection, or even advanced kidney disease. Unlike regular back pain, kidney pain doesn't improve with posture changes and should be taken seriously.
Constant itching
When the kidneys are unable to filter waste effectively, toxins accumulate in the blood. These toxins can irritate the skin, causing constant itching.
The itching often occurs beneath the skin and is not relieved by scratching or applying lotions. It can be so intense that it interferes with sleep and daily activities.
