Over-hydration as a key modifiable predictor of obstructive sleep apnea severity in dialysis patients with daytime sleepiness.

Article C Peer reviewed Observational

Key takeaways

Sleep apnea means breathing stops and restarts during sleep, and it is common but often missed in people on dialysis. Researchers studied 40 dialysis patients who felt very sleepy during the day, using a short questionnaire instead of an overnight sleep lab test. Patients carrying too much fluid in the body had worse sleep apnea, and fluid is something dialysis can adjust. This was a snapshot taken at one point in time at one center, so it shows a link, not proof that extra fluid causes the apnea.
