A JAMA Insights piece argues that clinicians treating obesity should be asking about sleep quality and quantity as a routine part of the consultation, on the grounds that sleep health is a modifiable contributor to both prevention and treatment.
It is worth being clear about what this is. Insights articles are short expert syntheses, not trials: there is no study population, no effect estimate and no new data behind it, and nothing here quantifies how much weight is attributable to poor sleep or how much a sleep intervention would return. What it does is name an omission. Obesity consultations run on diet, activity and increasingly pharmacotherapy, and sleep is rarely asked about unless the patient volunteers snoring.
The change is small and free. Two questions - how many hours, and how well - identify short sleep, shift work and the patients who should be screened for obstructive sleep apnoea, which is both common at this weight and independently worth treating. In a GLP-1 clinic in particular, untreated apnoea is a plausible reason for a patient who is losing weight to feel no better.
- Ask hours slept and sleep quality at the first obesity consultation and at review
- Screen for obstructive sleep apnoea where there is snoring, witnessed apnoea or daytime somnolence
- Ask about shift work explicitly - patients rarely offer it as relevant to weight
- Review sedatives and alcohol used as sleep aids before adding anything new
- Record sleep alongside weight so that a change in one can be read against the other
Why it matters
Sleep is the routinely omitted variable in a consultation that otherwise covers diet, activity and drugs.
Don't overread it
This is an expert commentary, not a trial - it establishes no effect size for sleep on weight and no benefit from treating sleep to treat obesity.
