Obstructive sleep apnoea-hypopnoea syndrome ( focus - OSAHS here ) and obesity hypoventilation syndrome in over 16s ( Summary )

This NICE guideline (NG202) covers the diagnosis and management of obstructive sleep apnoea/hypopnoea syndrome (OSAHS) and obesity hypoventilation syndrome (OHS) in people aged 16 and over. These conditions are frequently under-recognised despite their impact on daytime functioning, cardiovascular risk, and long-term morbidity. The guidance also includes considerations for people with COPD–OSAHS overlap syndrome, a subgroup at even higher risk of complications.

The guideline aims to improve clinical recognition, guide appropriate investigations, and recommend effective management strategies, especially relevant to primary care clinicians who are often the first point of contact. By enhancing early identification and timely referral, primary care can play a key role in reducing the burden of these conditions and improving patient quality of life.

Initial Assessment for OSAHS (NICE NG202)

Definition

OSAHS is a condition where the upper airway narrows or closes during sleep, causing apnoeas or hypopnoeas. These disruptions lead to sleep fragmentation and symptoms like daytime sleepiness, tiredness, or fatigue.
