• Obese patients suffer disorders of respiratory control. • Both obstructive sleep apnoea and the obesity hypoventilation syndrome are under-diagnosed. • Both syndromes have important implications for the perioperative course. • The obesity hypoventilation syndrome is characterised by reduced central respiratory drive and an elevated carbon dioxide tension while awake. • Obstructive sleep apnoea is characterised by nocturnal airway obstruction and desaturation. • Both syndromes are associated with cardiovascular complications and right heart failure. • Weight loss is an effective therapeutic strategy for both syndromes. • CPAP is effective in mitigating the effects of obstructive sleep apnoea.
