Obstructive sleep apnea (OSA) is a very commonly spread disease, not only in Bulgaria, but all over the world. One of the reasons for this is that patients suffering from OSA find it difficult to share their problem with their treating doctor (sleep doctor or ENT specialist). Doctor-patient communication is extremely important when gaining the patient'’s trust, for the early detection and diagnosis of obstructive sleep apnea. Sleep disorders lead to a decrease in the quality of life, due to frequent anxiety, fatigue, depressive states, reduced cognitive and motor functions, lack of energy, headaches and sleepiness throughout the day. Improving the quality of life of patients is a primary goal of the health care system, which is conveyed in patient care aimed at reducing or eliminating the effects of diseases and their associated negative psychological and social effects. Prevention, screening and effective communication with the patient are extremely important for a successful diagnosis and treatment of sleep disorders.
