Sign 11: Metallic Taste in the Mouth
A metallic taste in the mouth, also known as dysgeusia, can be a sign of renal failure. The accumulation of waste products in the bloodstream can alter your sense of taste, making food taste metallic or unpleasant. This symptom can also contribute to a loss of appetite and unintentional weight loss, as discussed earlier.
Addressing the underlying kidney issues and maintaining proper oral hygiene can help alleviate this symptom and improve your overall quality of life. (11)
