Obesity hypoventilation syndrome (OHS)

OHS is defined as chronic daytime hypercapnia (PaCOof over 45 mmHg) in obese patients (those with a BMI of > 30kg/m2) after ruling out any other causes of hypoventilation.1

As a result of poor breathing, those with OHS suffer from excess carbon dioxide (hypoventilation) and insufficient oxygen in their blood (hypoxemia).

OHS symptoms include:

Dyspnoea2, Excessive daytime sleepiness (EDS) 2, Morning headache2, Depression.

As many as 90% of patients with OHS also suffer from obstructive sleep apnoea (OSA).
