‘I’m a GP — follow these steps to prevent frailty in old age’

As an NHS GP, one of the things I see is how differently people age. Two patients may both be 80 years old, yet their lives can be very different. One may still be travelling, gardening and enjoying long walks, while another may struggle with activities such as climbing the stairs or shopping. A minor illness that one person shrugs off in a few days can leave another needing weeks of recovery. One reason for this difference is frailty.

What is frailty?

In medical terms, frailty is a state in which the body becomes less resilient. This means that even minor health problems have a much greater impact than they once did.

One person might recover quickly from a mild respiratory infection. Someone living with frailty, however, may become confused, lose their mobility, suffer a fall or require a hospital admission. Recovery is often slower and some people never regain the physical level they had before becoming ill.

Frailty develops gradually over many years through changes that occur throughout the body, including loss of muscle strength, reduced bone density and a decline in the ability of organs to cope with physical stress.

Although frailty becomes more common as we grow older, it is not just due to ageing. Many people remain fit, active and independent in later life.

Understanding what frailty is — and what can be done to prevent or delay it — is one of the keys to healthier ageing.

Why does frailty develop?

It usually results from a combination of factors. Ageing leads to loss of muscle mass and strength. Long-term medical conditions such as diabetes, heart disease or arthritis can accelerate this decline.

Poor nutrition, physical inactivity and smoking also increase the risk, along with social factors. Loneliness and isolation may lead people to become less physically active, eat less well and lose confidence in socialising. Over time, these changes can contribute to a gradual decline in health and independence.

Although frailty is most common in older age, it also affects younger adults. People with multiple long-term conditions, severe disabilities, or illnesses that reduce muscle strength and physical resilience may develop frailty when young.

How do doctors identify frailty?

General practitioners routinely look for signs of frailty in older patients. Increasingly, NHS computer systems use information already in medical records to help identify people who may be living with mild, moderate or severe frailty and who may benefit from additional support.

But no computer score tells the whole story. Frailty is best identified through a combination of medical information and clinical judgement. Doctors will consider how well someone manages everyday activities, their mobility, memory, nutrition and overall health.

Can frailty be prevented?

The good news is that frailty can be delayed or slowed. Regular physical activity is the single most effective measure. In particular, exercises that build muscle strength and improve balance help people maintain mobility and independence.

Walking is excellent for overall health but activities such as resistance training or climbing stairs also improve strength and reduce the risk of falls.

Eating a healthy, balanced diet is also important. Older people sometimes eat less than they need, particularly if they live alone or have a poor appetite. Adequate protein intake helps maintain muscle mass, while a varied diet rich in fruit, vegetables and whole grains supports overall health.

Avoiding smoking, limiting alcohol consumption and maintaining a healthy weight all contribute to healthier ageing. Keeping long-term medical conditions well controlled and attending routine health checks are also important.

Spending time with family and friends, joining community groups, volunteering or taking part in local activities can all support physical and mental wellbeing.

What if someone is already frail?

Many people living with frailty can improve their strength, confidence and quality of life with the right support. Exercise remains beneficial even for people who are already frail.

Doctors may also review medications to reduce side effects or stop medicines that are no longer needed.

Good nutrition becomes even more important once frailty has developed. Some people benefit from a dietitian’s advice, while others may require treatment for conditions such as osteoporosis to reduce the risk of fractures.

Falls prevention is another key part of care. This may include checking vision and hearing, reviewing footwear, making homes safer and encouraging appropriate physical activity. Small changes can make a big difference to maintaining independence.

Looking ahead

Helping people remain healthy and independent for as long as possible is becoming increasingly important for our society. Frailty is one of the major challenges but it is not an unavoidable consequence of ageing.

Many of the steps that reduce the risk of frailty also improve health more generally. While none of us can stop the ageing process, we can influence how well we age.

By adopting healthy habits throughout life, and by recognising frailty early when it develops, we can remain active, independent and enjoy a better quality of life.
