|Many people experience loss of sense of smell (olfaction) due to nasal problems or aging. Loss of smell can reduce safety (can’t smell gas leaks), reduce appetite, diminish quality of life, and increase risk of depression.|

A major cause of loss of smell involves fungi related chronic rhinosinusitis (nasal congestion). Earlier studies have reported that a majority of patients with rhinosinusitis are allergic to fungi (molds)- a condition known as allergic fungal rhinosinusitis (AFRS). One review of 101 consecutive surgically treated chronic rhinosinusitis patients repotred that 94 (93%) were diagnosed with AFRS.
