6. Metallic Taste or Bad Breath
A metallic taste in the mouth or persistent bad breath unresponsive to oral hygiene can indicate uremia, which is the accumulation of nitrogenous waste products in the blood due to kidney failure. This condition alters taste perception and produces a distinct ammonia-like odor known as “uremic fetor.”
These symptoms often appear in more advanced stages of kidney disease and can impact appetite and nutrition.
7. Shortness of Breath
Shortness of breath may arise from fluid accumulation in the lungs (pulmonary edema) when kidneys fail to regulate fluid balance. Additionally, anemia caused by reduced erythropoietin production in kidney disease lowers oxygen delivery, contributing to breathlessness during physical activity.
If you experience unexplained difficulty breathing, especially alongside other kidney symptoms, seek medical evaluation promptly.
8. Back or Side Pain
Pain in the lower back or sides beneath the ribs can be a sign of kidney stones, infection, or inflammation. This pain is usually persistent and may radiate toward the abdomen or groin. Unlike muscle soreness, kidney-related pain does not improve with rest or stretching.
Sharp or severe pain should be evaluated by a healthcare professional to rule out urgent kidney conditions requiring treatment.
