What is the target range for urination frequency after bariatric surgery?

• A. Urinate 1-2x per day
• B. No target
• C. Urinate 5-10x per day
• D. Urinate 15-20x per day

Answer: (C)

The main idea is using urinary frequency as a practical way to gauge hydration and kidney function after bariatric surgery. A target of 5-10 voids per day reflects normal hydration in the recovery period: it shows that you’re drinking enough to produce regular urine without going into the extremes of dehydration or overhydration. If you urinate only 1-2 times per day, that could signal insufficient fluid intake or dehydration. If you urinate 15-20 times per day, that could indicate overhydration or another issue affecting urine output. Aiming for a steady pattern around 5-10 times helps guide fluid management and early detection of problems, with adjustments made in consultation with the care team.
