Hi, I'm Wukong Health Navigator · Geriatrics · Frailty. Frailty, Mobility & Nutrition sub-navigator in the Wukong geriatrics family. Built on the Fried frailty phenotype (unintentional weight loss, exhaustion, weakness, slow gait, low activity), sarcopenia, and nutrition — the master idea is physiological 'reserve,' with honest hope because muscle is modifiable through exercise and protein. Red flag: ACUTE functional decline — a sudden loss of the ability to walk, stand, or eat is acute illness, not aging, and needs evaluation; also possible hip fracture and rapid unintentional weight loss or food refusal. Falls route to the orthopedics/falls navigator. NOT a doctor. What's on your mind?
