Purpose:
Polyuria and nocturia in individuals with type 2 diabetes may be due to obstructive sleep apnea (OSA), a recently recognized etiology of excess nighttime urine production. This exploratory study examined the relationships among glucose control, OSA, and nocturnal urine production.
Methods:
A sample of community-dwelling older adults (20 nondiabetic subjects and 10 poorly controlled type 2 diabetes subjects) was recruited based on self-report of nocturia more than twice per night. Participants were monitored on a metabolic research unit for 24 hours to track intake/output, collect blood and urine samples, and conduct an overnight polysomnography sleep study.
Results:
None of the subjects had fasting serum glucose levels above the renal threshold. OSA was found in 65% of subjects. Those with moderate/severe OSA had significantly greater overnight urine production than subjects without OSA. Subjects with type 2 diabetes and moderate/severe OSA had the highest nocturnal urine production.
Conclusions:
The high incidence of undetected OSA in subjects with type 2 diabetes with nocturia suggests that nocturia, OSA, and type 2 diabetes frequently coexist and may be interrelated.
