Menopause has been associated with olfactory dysfunction, or an impaired sense of smell. A study found that women who reached menopause at a younger age experienced reduced smell sensitivity in postmenopause. Although most research shows a reduction in smell sensitivity, some women report a heightened sense of smell during the transition.
Some women may also experience phantosmia, or phantom smell, in menopause. This condition is characterized by olfactory hallucinations wherein someone perceives smells that are not actually present. While there’s not enough research on the cause of this condition, it’s been linked with hormonal changes during menopause.
People with phantosmia often perceive unpleasant odors, like smoky, burnt, or rotten smells. However, although rare, some may perceive pleasant odors, like flowers or perfume.
