Partial or complete loss of smell can occur not only due to coronavirus, but also due to other dangerous diseases, warned doctor Alena Paretskaya.
Progressive diseases of the central nervous system, such as Alzheimer's, may be the most serious cause of anosmia, she said. That being said, the gradual loss of the ability to smell can be a natural part of aging.
In addition to senile changes, the use of certain medications or exposure to toxic chemicals can cause a problem, she said.
Also, this symptom may indicate hormonal imbalance or dental problems. In addition, a sharp loss of smell can be a manifestation of a head injury, severe injuries of the upper part of the nose, polyps in the sinuses or nasal passages, and a gradual loss of sinus inflammation, chronic obstruction from infections or an allergic reaction, reports KP.RU.
