Our sense of smell defines our relationship with food, our sense of wellbeing, confidence and relationships with others so the impact of smell loss is serious. It also affects our ability to appreciate food and drink. If you can’t taste food normally, a smell disorder could be the cause.
Smell happens when volatile molecules of a substance, for instance a cut lemon, mingle with the air. When they enter our nose, they stimulate olfactory nerve cells found high in the nasal cavity. These nerves send messages to the brain that help us interpret what we are smelling.
