6. Bad Breath and Metallic Taste
When waste products build up in the blood due to kidney dysfunction, it can alter the taste of food and leave a metallic taste in the mouth. Additionally, foul breath may indicate an accumulation of toxins in the bloodstream. This can also lead to a loss of appetite, particularly for meat, resulting in unintended weight loss.
Important Note: A metallic taste in the mouth can be caused by several factors, from allergies to poor oral hygiene. If the taste persists after addressing any underlying issues, consult your doctor.
