beginning of content Losing your sense of smell can mean you miss out on experiences that other people may take for granted, such as the scent of perfumes or cooking. This article looks at anosmia, the medical term for loss of smell, and its causes, symptoms and treatments. Show What causes anosmia?You can be born with anosmia, but there are many things that can cause it throughout life. These include:
Some people never find out what caused them to lose their sense of smell. If you have a cold or flu, your sense of smell will usually come back within a week or 2. Otherwise, it's a unpredictable — in some cases, anosmia can be permanent. If a person has a partial sense of smell, it's called hyposmia. Many things — including smoking, a cold or flu, depression, schizophrenia, seasonal affective disorder and ageing — can cause hyposmia. How anosmia affects youObviously, if you have anosmia, you can't smell anything. But because the sense of smell is so closely connected to the sense of taste, you may find that food tastes bland.
