The term "anosmia" refers to the loss of one's sense of smell. There are several drugs, disorders, hormonal changes, and substances that might permanently impair one's sense of smell. People become less sensitive to scents as they age, and women have a more poor sense of smell than males. To some extent, there is evidence that scent sensitivity is inherited.Even a slight loss of scent may cause you to lose interest in eating, which can lead to weight loss, poor nutrition, or, in severe cases, depression.
Sometimes a person's sense of smell returns on its own. Unfortunately, anosmia is not always curable, especially if it is caused by old age. There are, however, things you may do to make life with the inability to smell more comfortable and secure. Install smoke and fire alarms in your house and business, for example, and take additional precautions with leftovers. If you have any doubts regarding the safety of a food, don't consume it. This is demonstrated in See what I mean: the extraordinary powers of our five senses By Laurence Rosenblum. When Karl Wuensch was diagnosed with anosmic.
