Which term means needing to wake up at night to urinate?

• A. Nighttime Urination
• B. Nocturia
• C. Nycturia
• D. Nocturnal Diuresis

Answer: (B)

Nocturia describes waking up during the night specifically to urinate. It’s a common symptom that signals a disruption of sleep due to the need to void, and it can arise from increased nighttime urine production, reduced bladder capacity, or other factors like medications or sleep disorders. The other terms don’t fit as well: a casual phrase like nighttime urination isn’t a standard medical label; nycturia isn’t used in modern terminology; nocturnal diuresis refers to urine production at night (which can contribute to nocturia) but does not itself define the act of waking to urinate.
