Anosmia (Loss of Smell) – Causes, Symptoms, Diagnosis and Treatment

Anosmia is the loss and disturbance of the sense of smell and is intended as a resource for sufferers from olfactory disorders. Our smell nerves (olfactory nerves) are situated behind the eyes and above your nose. Airborne substances that are inhaled stimulate these nerves and allow you to perceive your sense of smell. It can be temporary or permanent depending on the cause.
Loss of smell could cause you to lose interest in eating, leading to weight loss, malnutrition or even depression. Loss of smell also prevents you from smelling things like spoiled food or smoke.
