Overview of Altered Taste Sensation
When someone has dysgeusia, their sense of taste is affected; everything appears to be metallic, sweet, sour, or bitter. Adults with taste issues are not uncommon. According to research conducted on individuals in the US, up to 17% of those evaluated exhibited some sort of taste impairment.
- Foods with dysgeusia taste strange due to a taste problem. This altered sense of taste usually disappears on its own.
- Dysgeusia can be brought on by a regular cold or a virus such as COVID-19. It could be an adverse reaction to another medicine or treatment.
- Dysgeusia frequently occurs in pregnancy and in cases of specific vitamin deficits. Once the underlying cause has been addressed, it usually disappears.
- Although it affects your quality of life, dysgeusia is not harmful or life-threatening.
