• 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.
