The process of smelling involves your nose and your brain. The inside of your nose contains special cells called olfactory neurons. These neurons, or odor receptors, send your brain messages about scents they detect. When your brain receives one of these messages, it recognizes and identifies the smell. A problem or blockage anywhere in this process can affect your ability to smell.
Usually, anosmia and hyposmia improve once doctors have treated the cause. In some cases, loss of smell can be permanent. If you notice symptoms of anosmia, it is important to seek treatment right away. Delaying treatment may result in permanent smell loss.
Treatments may include changing medications, treating an infection (such as COVID-19), smell retraining therapy, or surgery to remove a blockage. Our world-renowned team has unparalleled expertise in smell disorders. Your care team will work with you to determine the most appropriate treatment plan.
