Michael Berg is one individual who had strange sinus problems for most of his adult life, as he had reactions after drinking a glass of wine or smoking a cigar. Doing either of these activities would drastically reduce his ability to smell anything, the news source reported.
The Chronicle reported that after he experienced these strange side effects for several years, in 2005, his sense of smell completely vanished.
"Literally one day we were having dinner, and I remember I couldn't smell or taste anything," Berg, 55, told the news source.
Experts estimate that about two percent of the US population suffers from Berg's condition, a lack of smell known as anosmia. Researchers, led by neuroscientists at UC Berkeley, have provided hope of new therapies for those who have this affliction, regardless of how these individuals ended up with the disorder.

"The loss of the ability to smell is actually a huge public health problem," Ngai said. "It is underreported, not well understood and not aggressively pursued...It is an underappreciated problem."
People who lose their sense of smell often lose their sense of taste. Together, according to the Chronicle, the two senses create the will to ingest nutritious foods and prevent people from eating toxic substances.
The FDA advised consumers not to use certain Zicam cold remedies due to the fact that there is a risk that users will develop anosmia, according to a release from the organization.
