Waking once or more each night to pass urine (nocturia) is common with age and disrupts sleep. It has several treatable causes — from an enlarged prostate to diabetes or heart conditions.
Drinking a lot in the evening, or caffeine/alcohol
Diabetes (high sugar), or fluid shifting from swollen legs at night
Tips: limit evening fluids, elevate swollen legs earlier in the day
Treat the cause (prostate, bladder, diabetes, heart)
When to see a doctor urgently
Very frequent urination with excessive thirst and weight loss (check for diabetes)
Burning urine or fever (possible UTI)
Blood in the urine
Nocturia with breathlessness or leg swelling (possible heart cause)
Find the cause. Nocturia is not just “old age” — an enlarged prostate, diabetes, bladder or heart conditions may be treatable causes. It also raises fall risk at night. MedDroid gives general information, not a diagnosis.
