Mouth device may cut nightly bathroom runs for sleep apnea sufferers

This study tested whether a mandibular advancement device (MAD) — a mouthpiece that moves the jaw forward — can reduce how often people with obstructive sleep apnea wake up to urinate at night. Eleven adults with sleep apnea and at least two nightly bathroom trips took part. Participants used the device and tracked their nighttime urination; if they averaged fewer than two trips per night, a follow-up sleep study checked for breathing improvements.
