! Sleep Apnea & Diabetes: Sleep apnea is strongly linked to insulin resistance and poor glucose control. If diagnosed, untreated apnea can make diabetes management significantly harder. Speak with your healthcare provider about CPAP therapy and schedule an HbA1c check.

    How This Works

    This calculator scores the impact of five sleep dimensions on glucose control, using a research-weighted composite score (0-12):

    Duration(<6h:+3, 6-7h:+1, 7-9h:0, >9h:+1) + Quality(poor:+3, fair:+2, good:0, excellent:-1) + Wake-ups(>3:+2, 1-3:+1) + Inconsistency(no:+1) + Apnea(diagnosed:+3, suspected:+2)

    Why sleep matters for blood glucose: During sleep, the body regulates cortisol and growth hormone - two hormones that directly raise blood glucose. Poor or insufficient sleep elevates cortisol, increases insulin resistance, and triggers hunger hormones (ghrelin) that drive carbohydrate cravings the next day.

    Just one night of 4-5 hours sleep can reduce insulin sensitivity by up to 25% - equivalent to gaining 10-15 kg of body weight in metabolic terms. Chronic sleep deprivation is now considered an independent risk factor for type 2 diabetes.

    Sleep apnea is particularly significant: untreated sleep apnea causes repeated micro-arousals that spike cortisol throughout the night, directly impairing glucose control. Up to 80% of people with type 2 diabetes have undiagnosed sleep apnea.
