What is the term for excessive nighttime urination?

The term for excessive nighttime urination is nocturia. This condition is characterized by the need to wake up during the night to urinate, which can disrupt sleep and affect quality of life. Nocturia can be caused by various factors, including fluid intake before bedtime, underlying health conditions, or medications.

Understanding nocturia is important as it can serve as a symptom of other medical issues, such as diabetes or urinary tract infections, and addressing it can significantly improve an individual’s nightly rest and overall health.

The other terms listed do not pertain to nighttime urination: hematuria refers to the presence of blood in the urine, aplastic anemia is a condition where the bone marrow does not produce sufficient blood cells, and pernicious anemia is related to a deficiency of vitamin B12 due to poor absorption in the intestines. Each of these terms describes different medical conditions with distinct implications, making nocturia the correct choice in this context.
