11.Brain Surgery
It’s not common, but your sense of taste can change after brain surgery to remove a tumor. The surgery itself might be the reason. Or it may be due to nerve damage that causes disorders like Bell’s palsy, a condition that temporarily numbs the nerves in your face.
12.Chemicals
If your job puts you in the path of metal fumes like zinc oxide, it might mess with your sense of taste. Welders are at high risk of a condition called metal fume fever. It makes you very thirsty and causes a metallic taste in your mouth. It typically goes away in 6-12 hours.
