The Nocturia Feedback Loop

A five-stage feedback loop links sleep disruption, fatigue and inactivity, worse metabolic and vascular health, fluid redistribution and sleep-apnea risk, and increased nighttime urine or awakening. Realistic staged patient scenes accompany medical diagrams. Dotted intervention points include sleep evaluation, fluid and diuretic timing, fall-proofing, edema assessment, bladder treatment and metabolic care. This is a conceptual model of interacting factors, not proof that every arrow is causal in every patient.
