Frequent Nighttime Urination
Urinating frequently at night, also known as nocturia, is highly associated with obstructive sleep apnea (OSA). Untreated OSA often results in increased production of atrial natriuretic peptide (ANP), which is one of our body’s natural diuretics – a hormone that works to remove fluid from the body. The end result is frequent urination during nighttime hours while OSA is occurring. Frequent nighttime urination can also be the result of certain medical problems, such as prostate problems in men.
