ABSTRACT
Weight loss, either through dietary means or
by bariatric surgery will significantly reduce
the severity of OSA, but the effect is variable
and therefore it is important to re-assess
patients after weight loss. Recent data from
the Swedish Obese Subjects study have shown
a marked reduction in sleep apnoea
symptomatology in obese subjects 2 years after
surgically-induced weight loss compared with
controls. However, complete cure of all sleep-
disordered breathing with weight loss is rare:
many patients have significant residual disease
that warrants further treatment.42
