Frequent urination at night, known as nocturia, can be caused by several factors including producing excess urine at night, decreased bladder capacity, or sleep disruptions. Common reasons are increased urine production specifically at night (nocturnal polyuria), bladder issues such as infections or an overactive bladder, and sleep disorders like obstructive sleep apnea. Other contributing factors include older age, drinking too much fluid (esp. alcohol or caffeine) before bedtime, certain medications (diuretics), diabetes, enlarged prostate in men, and swelling in the legs that shifts fluid when lying down. Nocturia can also be a symptom of underlying health conditions that affect kidney function, heart, or blood sugar control.
If this is causing distress or sleep disruption, it is advisable to track fluid intake and urination patterns and consult a healthcare provider for appropriate diagnosis and treatment options.
