Nocturia is defined as the frequent need to get up at night to go to the bathroom. It is a common presenting symptom and is found in 80% of Obstructive Sleep Apnea patients. Most people think that it is because they had too much to drink or drank something too late at night. Others feel that they just have a small bladder that can’t last the whole night. What is most likely occurring is that the patient is suffering from Obstructive Sleep Apnea. As a result of these obstructions, hormones are released that directly act on the bladder to cause contractions. This results in the feeling of urgency when one awakens from the obstructions. Additionally, Polyurea or increased volume of urine is found in Apnea patients. Research has shown higher volumes of urine produced during the night in patient’s suffering from Obstructive Sleep Apnea.
