Disease Description (Causes and Symptoms)
- Definition: Frailty is a state in which the physiological reserve to withstand internal and external stressors on the body has decreased; it is a pathological condition distinct from normal aging. Even a small, unexpected stressor can cause a rapid decline in function, increasing the risk of disability, hospitalization, and death.
- Main pathophysiology: Physical reserve decreases through the combined effects of reduced muscle mass and strength (sarcopenia), decreased energy metabolism, increased inflammatory responses, hormonal imbalance, malnutrition, and polypharmacy.
- Main causes: In addition to advanced age itself, inadequate management of chronic diseases, nutritional deficiencies, reduced activity levels, adverse drug effects, depression, cognitive decline, and hormonal abnormalities.
- Common symptoms: Loss of appetite, weight loss (especially muscle loss), general fatigue and decreased energy, slow walking and unstable balance, lower-extremity muscle weakness (slower gait), dizziness, and decreased memory.
- Diagnostic methods (main indicators used): Fried’s physical frailty criteria (weight loss, exhaustion, weak grip strength, slow walking speed, and low physical activity) — 3 or more indicate frailty, while 1–2 indicate prefrail status. A comprehensive geriatric assessment (CGA) is used to evaluate sarcopenia, nutritional and cognitive status, fall risk, medication review, and other factors comprehensively.
Treatment Methods
- Treatment goals: Delay the progression of frailty and restore function, while reducing the risk of complications (falls, hospitalization, and death).
- Nonpharmacological treatment (key)
- Multicomponent exercise (recommended core): A combined program including resistance (strength) training + balance training + aerobic exercise. Frequency: at least 2–3 times per week, with gradually increasing intensity. Physical therapy and exercise prescription (rehabilitation medicine) are recommended.
- Nutritional management: Adequate calorie and protein intake (recommendation: generally 1.0–1.2 g/kg/day for older adults; 1.2–1.5 g/kg/day may be considered for those with nutritional deficiencies or frailty), divided protein intake, calorie supplementation, and, when necessary, nutritional supplements (high-protein drinks and preparations containing HMB may be considered).
- Combined intervention: Exercise combined with nutrition is the most effective.
- Medication and medical management
- There is no specific medication for treating frailty. Underlying diseases (such as anemia, infection, endocrine diseases, and heart failure) should be appropriately treated.
- Supplement vitamin D in cases of vitamin D deficiency (general recommended amount, for example: 800–1000 IU/day; adjust according to blood levels).
- Hormone therapy (e.g., testosterone) is used selectively and to a limited extent; its benefits and risks (including cardiovascular and prostate-related risks) must be carefully considered.
- Medication review (reducing polypharmacy): Minimize medications that may cause adverse effects, such as anticholinergics, sedatives, and excessive antihypertensive medications.
- Other
- Strengthen fall prevention (improving the home environment and using assistive devices), vaccinations (such as influenza and pneumococcal vaccines), and social support (caregiving and nutritional support).
- Precautions
- Walking alone for long periods or an extremely low-calorie or predominantly vegetarian diet may worsen the condition.
- Because frailty increases the risk of complications and death during major stressors such as surgery, thorough management before and after surgery is necessary.
Outpatient Visit Checklist (Including Preparation Items and Example Questions)
- Preparation items
- A list of all medications currently being taken (including prescriptions, over-the-counter medications, and health functional foods) and the times they are taken
- Records of recent weight changes (duration and amount of any abnormal changes)
- History of falls (whether a fall occurred within the past year and the circumstances)
- Records of activity level (daily step count and type of exercise) and changes in ADL/IADL function
- Recent test results (blood tests: CBC, serum albumin, electrolytes, kidney function, thyroid function, vitamin D, etc.)
- Notes on food intake and eating patterns (number of meals and protein intake)
- Key information to provide to medical staff during an outpatient visit
- Weight change over the past 6–12 months (%) — e.g., whether there has been a loss of 5% or more
- When and how fatigue, reduced activity, and changes in walking speed occur in daily life
- Recent history of hospitalization, infection, or medication changes
- Example checklist questions (for preparing for a doctor’s consultation)
- "How much weight have you lost over the past year?" / "Has your walking speed slowed down?"
- "Over the past few months, how many days have you been unable to stay active without taking a break?" / "Have you experienced any falls?"
Examples of General Questions to Ask the Doctor
- "How did you determine whether my condition is frailty or prefrail status? What tests or criteria did you use?"
- "What specific changes do I need to make to my lifestyle (exercise and nutrition)? How many times per week and at what intensity do you recommend exercising?"
- "Are any of the medications I am currently taking affecting frailty? Should any be reduced or changed?"
- "What is the prognosis? How much recovery can be expected with appropriate treatment?"
Examples of Disease-Specific Questions (1–2)
- "How much protein should I consume per day (in g per kg of body weight)? How should I structure example meals?"
- "Could you recommend a specific exercise program (number of sessions per week, sets, and intensity) suited to my current exercise capacity (e.g., walking speed and grip strength)?"
(Note: Diagnosis and treatment vary depending on the individual’s condition. Consult your treating medical professionals to determine an accurate diagnosis and treatment plan.)
