About the department

The pulmonology department at Memorial Sisli Hospital Istanbul offers modern diagnostics and treatment for diseases of the lungs, bronchi and upper respiratory tract. The department employs a highly professional team of doctors for whom patients' health and needs always come first. The medical institution uses carefully designed pharmacotherapy regimens, and in complex cases, artificial lung ventilation is performed in specially equipped wards. Patients receive medical care in both inpatient and outpatient settings. Before treatment, the specialists of the department conduct a complete diagnostic examination, including endoscopic ultrasound, computed tomography (CT), positron emission tomography (PET-CT), magnetic resonance imaging (MRI) and laboratory tests. The department doctors are members of the Turkish Respiratory Society, so patients are treated according to the latest therapeutic recommendations.

Specialists have unique experience treating chronic obstructive pulmonary disease, bronchial asthma, interstitial lung disease, respiratory infections and pleural diseases. In addition, the doctors of the department specialize in the treatment of sleep disorders and snoring. Doctors conduct a comprehensive respiratory system diagnosis, recommend breathing exercises and physiotherapy, and prescribe medications to improve the patient's well-being and restore his vitality.
