“My beautiful burger tasted disgustingly metallic. It was inedible. It was so awful, I scraped the rest of it right into the trash. But that was only the first of many formerly favourite foods that have ended up in the trash lately”
This phenomenon is what’s known as chemo mouth or metal mouth, according to pharmacist Dr. Jessica Caporuscio. She explains that unpleasant side effects – including these taste alterations – are unfortunately common during cancer treatments.
This bizarre side effect occurs because cancer treatments can activate certain receptors in the mouth or tongue that cause this metallic reaction.
While it can be distressing, the metallic taste and other taste changes usually resolve after treatment is complete.
