Kidney disease occurs when an illness or injury disrupts the functioning of a person’s kidneys. Since the kidneys act as a filter to remove wastes and other byproducts from the human body, the gradual loss of functioning can lead to the build up of dangerous wastes and fluids in a person’s system. Early on, the symptoms of kidney disease are often mild and steadily progress in severity as the disease becomes chronic.
1. Decreased Urine Output
As kidneys filter wastes from the body, they produce urine. For this reason, urinary problems are one of the more common symptoms of kidney disease. Decreased urine output is one symptom that many people notice; yet, it is important to note that some people’s output remains normal. As a result of the decreased output, the urine may also become more concentrated and darker in color.
