If you have experienced a loss in your sense of smell, you should seek evaluation by a board-certified otolaryngologist (ear, nose and throat specialist), preferably at a large university medical center, to determine if the cause can be identified and if you may respond to treatment.
Anosmia is a diverse disorder having many possible causes. Unfortunately, at the present time, there are relatively few forms of smell problems for which the underlying cause can be conclusively identified. And without knowing exactly what caused the smell loss, treatment options are limited. Finally, it often is difficult to predict who will and who won’t respond to treatment.
