Shortness of Breath
Failing kidneys may cause two issues that lead to breathlessness. First, excess fluid may build up in the lungs, making it hard to breathe. Second, poor kidney function can reduce red blood cell production, lowering oxygen levels in the body.
If you feel breathless after light activity or even while resting, it may be time to check your kidney health.
Puffy Eyes
Puffiness around the eyes, especially in the morning, can signal protein leakage in the urine.
Because this is one of the earliest signs of kidney dysfunction, it should never be ignored. Puffy eyes are often mistaken for lack of sleep, but when persistent, they may point to a more serious issue.
Muscle Cramps
Electrolytes like calcium, magnesium, and phosphorus are balanced by the kidneys. When this balance is disrupted, painful muscle cramps occur.
These cramps often affect the legs, arms, or back and can strike suddenly. Chronic kidney issues increase the frequency and intensity of such cramps.
Metallic Taste in Mouth
When waste builds up in the blood, it can leave a metallic or ammonia-like taste in the mouth. Some people also experience “uremic breath,” which smells unpleasant.
This change in taste may also make food less enjoyable, leading to reduced appetite and weight loss.
