Frailty: Common Questions
A state of reduced physiological reserve in which minor illness produces disproportionate decline.
Last revised
Frailty: the questions people actually ask, answered from published guidance.
Key takeaways
- Markers: slow walking speed, weight loss, exhaustion, low activity, weak grip
- Most effective intervention: resistance exercise and adequate protein
- Most useful single change: Do resistance exercise; it is the single most effective intervention.
- Commonest mistake: Accepting decline as inevitable.
- See a doctor if any of the signs under "When to get help" below apply to you.
What is Frailty?
A state of reduced physiological reserve in which minor illness produces disproportionate decline.
Why does it matter?
It is not an inevitable consequence of age and it is partly reversible, particularly through exercise and nutrition.
Most effective intervention for Frailty?
Resistance exercise and adequate protein.
Protein, older adults for Frailty?
Often advised at 1.0-1.2g per kg a day.
Comprehensive geriatric assessment for Frailty?
Improves outcomes.
What is the single most useful thing to do?
Do resistance exercise; it is the single most effective intervention.
What is the most common mistake?
Accepting decline as inevitable.
When should I see a doctor?
Seek prompt assessment for unintentional weight loss, repeated falls, new confusion, or a sudden decline in function — in older adults these often indicate acute illness rather than gradual ageing. Any acute change over hours or days warrants urgent review.

How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
