DEAR DOCTOR K: I'm an older woman in good health, but I can't get a good night's sleep because I keep waking up to go to the bathroom. What can I do?
DEAR READER: "Nocturia" is the medical term for the need to get up frequently to urinate during the night. It's a common cause of sleep loss, especially among older adults. In severe cases, a person may get up as many as five or six times during the night. This can lead to sleep deprivation and daytime fatigue.
