An ENT doctor named diseases that worsen in winter. The causes of exacerbations are a weakened immune system, hypothermia and complications from previous acute respiratory viral infections (ARVI), he explained.

An endoscopic research method is used to diagnose ENT diseases, which allows one to qualitatively assess the condition of organs. The doctor noted that prevention of ENT diseases mostly involves maintaining a healthy lifestyle. Earlier, therapist Nadezhda Chernyshova explained what nutrition should be like during illness.
