Extended duration of rotating night shift work (defined as ≥3 nights/month) is associated with a modestly increased risk of developing type 2 diabetes in women, independent of lifestyle factors.
If you work rotating night shifts, your risk for type 2 diabetes is higher than day workers, even if you maintain a healthy weight. This is due to biological disruption of your body's internal clock, not just lifestyle choices. You should prioritize regular medical screening for blood sugar levels and discuss specific circadian health strategies with your healthcare provider, as standard lifestyle advice may need to be adapted for shift work.
Our results suggest that an extended period of rotating night shift work is associated with a modestly increased risk of type 2 diabetes in women, which appears to be partly mediated through body weight.
Why this rating
Large prospective cohort studies (NHS I and II) with long follow-up (18-20 years) and rigorous adjustment for confounders, though observational design limits causal inference.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
