I'm worried about how little I am urinating. Can easily go 12 hrs without having any urge. Is this normal?

See answer . Infrequent urination in an otherwise healthy person implies one of two causes: 1) low urine output/production related to decreased intake or excessive body or exercise-related losses or 2) large bladder capacity bladder. Can obtain answer(s) by measuring your total 24-hr urine output (average 40-60 ounces) and how much you urinate each void (average 10-15 ounces). ••low fluid intake most common.
