Urologists diagnose nocturia through a structured, step-by-step evaluation: 1. **Fluid intake review and bladder diary** to track urine volume, timing, and frequency patterns. 2. **Medical history assessment** to identify contributing conditions such as diabetes, heart failure, or sleep apnea. 3. **Physical examination** focused on the abdomen, pelvis, and prostate (in men). 4. **Targeted lab tests and specialized studies**, including urinalysis, blood work, or urodynamic testing. This systematic process helps determine whether nocturia stems from nighttime urine overproduction (nocturnal polyuria), reduced bladder capacity, sleep disorders, or underlying systemic disease.

**What Are Pressure Flares? Causes, Symptoms, and Treatment** Pressure flares are delayed skin welts caused by prolonged or intense pressure on the skin—like sitting on hard surfaces, carrying heavy bags, or wearing tight shoes.
