Night urination linked to snoring New Delhi, August 07, 2016: Sleep apnea, a common but serious sleep snoring disorder, is the root cause of nocturia, or getting up frequently during the night to urinate said Padma Shri Awardee Dr KK Aggarwal – President Heart Care Foundation of India (HCFI) and Honorary Secretary General IMA. The results of a study conducted by researchers at the University of Alabama at Birmingham, which reported these findings are particularly important for older adults who are at greater risk of falling and being hurt if they must get up frequently during the night to urinate. People with nocturia often report the problem to their gynecologist or urologist but not a sleep clinician. Doctors most often attribute nocturia to aging in women or to prostate problems in men. One event per night is within normal limits but two or more events per night may be associated with sleep deprivation. In sleep apnea, the soft structures in the throat relax and close off the airway. Oxygen decreases, carbon dioxide increases, the heart rate drops and blood vessels in the lung constrict. The heart starts racing and experiences a false signal of fluid overload. Body tries to get rid of sodium and water, resulting in nocturia. In sleep apnea airway obstruction lasts for 10 seconds or more, and occurs five or more times per hour of sleep. People with the most severe cases of sleep apnea can have more than 100 such events per hour of sleep. Symptoms include snoring, restless sleep with frequent awakenings, excessive daytime sleepiness, and morning headaches.
