Secondary prevention
Obese patients should be advised about weight loss; weight loss counselling and planning should be offered. Improvement in AHI may be lost with subsequent weight gain, and it is recommended that the importance of maintaining lower weight is emphasised to patients.[12][198][199]
Tobacco smoking, alcohol, and sedative consumption may exacerbate OSA and should be avoided or limited if possible. Sleeping in a non-supine position may reduce the frequency and severity in some patients.
