Obstructive sleep apnea syndrome is far more common than generally believed. The Indian population where obesity rates are also increasing also has a very large population with undiagnosed OSAHS. The association of OSAHS with cardiovascular abnormalities further complicates the disease. Understanding the pathophysiology of OSA in obese and non-obese persons helps in evaluation, diagnosis and management in the individual group. With wider availability of PSG tests and newertreatment modalities, diagnosis and management of OSAHS has become easier. Increasing awareness regarding OSA and OSAHS among the general population and clinicians, wider availability of PSG studies and decreasing the costs of diagnostic tests and treatment can go a long way in identifying and treating these patients.
