4 Jul 2025 • In a study of Indian patients undergoing sleep studies, 5.8% were diagnosed with obesity hypoventilation syndrome (OHS), nearly all alongside obstructive sleep apnea (OSA).

OHS prevalence rose with BMI—9% in BMI 30–40 and 20% in those >50 kg/m². Key predictors included female gender (OR = 4.1), BMI ≥ 35 kg/m² (OR = 3.2), and orthopnea (OR = 4.8).

Findings highlight the need for targeted screening in high-risk groups to avoid missed diagnoses.
