Chapter 2: Changes in Urination
One of the earliest signs of kidney problems may involve changes in urination patterns.
Some people notice they need to urinate more frequently, especially during the night. Others may experience reduced urine output, difficulty urinating, or urine that appears foamy due to excess protein.
Blood in the urine can also occur and should always be evaluated by a medical professional. Urinary changes do not necessarily indicate kidney disease, but they often signal that something requires attention.
Another possible warning sign is dark-colored urine or unusual changes in odor. Monitoring these changes can provide important clues about overall kidney health.
Chapter 3: Swelling and Persistent Fatigue
Healthy kidneys help regulate fluid balance. When kidney function declines, excess fluid may accumulate in tissues, leading to swelling.
