What is dysgeusia and what can cause it?

Dysgeusia is a condition characterized by a distorted or altered sense of taste, where individuals may experience a persistent metallic, salty, or bitter taste in their mouths. It can be caused by various factors, including certain medications (such as antibiotics or chemotherapy drugs), medical conditions (like Diabetes or neurological disorders), nutritional deficiencies (especially zinc), and exposure to environmental toxins. Additionally, oral health issues, such as infections or gum disease, can also contribute to dysgeusia.
