Needing to urinate very frequently — day and night — has several treatable causes. In Lagos, diabetes and urinary infection are the most common. This page explains the causes, the tests, and when to come in.
Frequent urination (polyuria or urinary frequency) is different from normal — most adults urinate 6–8 times per day. More than that, or waking more than once at night, warrants investigation.
High blood sugar causes glucose to spill into the urine, pulling water with it — causing frequent, large-volume urination, often with excessive thirst. A fasting blood sugar and HbA1c diagnose it.
Frequent, urgent, small-volume urination — often with burning. The most common cause in women. A urine dipstick and culture diagnose it.
In men over 50 — frequent urination, especially at night (nocturia), weak stream, and incomplete emptying. A prostate scan and urine flow test assess it.
A rarer condition — very large volumes of dilute urine, extreme thirst, no glucose in urine. Caused by ADH (antidiuretic hormone) deficiency or resistance.
A sudden, urgent need to urinate even with a partially empty bladder — often without infection. Associated with stress or neurological causes.
Frequent urination is a very early pregnancy symptom — the uterus pressing on the bladder. A pregnancy test is always first.
Urine Dipstick — Checks for glucose (diabetes), blood, protein, and nitrites (infection) — results in 5 minutes.
Fasting Blood Sugar + HbA1c — Essential if dipstick shows glucose — confirms or excludes diabetes.
Urine Culture & Sensitivity — Confirms UTI and identifies the correct antibiotic — results in 48 hours.
Prostate Scan + Post-Void Residual (Men) — Assesses prostate size, bladder function, and residual urine volume.
Kidney Function Test — Creatinine and eGFR — especially if diabetes is found, to assess renal baseline.
Frequent urination + excessive thirst + weight loss = possible diabetes. Frequent urination + burning = UTI. Frequent urination + weak stream (men) = BPH.
A urine dipstick at Mascot Healthcare takes 5 minutes and immediately narrows the diagnosis.
Worsening frequency in a known diabetic suggests blood sugar is not controlled. Book an HbA1c.
Frequent urination without burning or pain may not be a UTI — it may be diabetes, overactive bladder, or early pregnancy.
