What is Geriatric Medicine?

Geriatric medicine is the medical specialty concerned with the health and wellbeing of older adults, particularly those aged 65 and above who are living with multiple chronic conditions or age-related complexity. Rather than focusing on a single organ system, geriatric medicine takes a whole-person approach, addressing the medical, functional, cognitive, and social factors that together determine how well an older person is able to live independently and safely./p>

As people age, the body undergoes natural physiological changes, and the likelihood of developing chronic conditions such as diabetes, hypertension, heart failure, and continence problems increases. Managing the health of an older adult with several overlapping conditions, medications, and needs can be considerably more complex than managing any one condition alone. Geriatricians are trained specifically to navigate this complexity, helping older adults manage their health, improve their quality of life, and maintain their independence for as long as possible.

Understanding Geriatric Medicine

Geriatric medicine differs from other specialties in that it is organised around the patient rather than around a single organ or disease. A geriatrician looks at how a person's various medical conditions, medications, cognitive function, mobility, and living environment interact with one another, since a change in one area, such as a new medication or a minor illness, can have a disproportionate effect on an older adult's overall function.

This is why the specialty places particular emphasis on age-related issues such as falls and balance, osteoporosis, memory problems and dementia, and mood and sleep disorders, alongside the more familiar chronic diseases of ageing. The aim is not simply to treat each condition individually, but to build a coordinated plan that protects a patient's overall function, safety, and independence.

Key Areas of Focus

Geriatricians assess and manage several interconnected areas of health that become increasingly important with age:

Comprehensive Geriatric Assessment: A structured, multidimensional review of an older adult's medical, functional, cognitive, and social status, used to build a coordinated care plan rather than treating each condition in isolation.
Falls and Balance: Assessment of gait, balance, muscle strength, and home safety to identify and reduce the risk of falls, a leading cause of injury and hospitalisation in older adults.
Memory and Cognition: Evaluation and management of memory problems, mild cognitive impairment, and dementia, including distinguishing these from normal age-related changes.
Polypharmacy and Medication Review: Review of all medications a patient is taking, to reduce unnecessary drugs, avoid harmful interactions, and adjust dosing appropriate to an ageing body.
Continence: Assessment and management of urinary and bowel continence issues, which are common but often under-reported in older adults.
Frailty and Functional Decline: Identification of frailty, a state of reduced physiological reserve, and strategies to preserve strength, mobility, and independence.
Mood and Sleep: Recognition and management of depression, anxiety, and sleep disturbances, which can be more difficult to detect in older adults and are sometimes mistaken for normal ageing.

Common Conditions Managed in Geriatric Medicine

Geriatricians diagnose and manage a broad range of conditions and issues commonly encountered in older adults, including:

Dementia: An umbrella term for a set of symptoms caused by a combination of neurological disorders, affecting memory, thinking, and the ability to carry out everyday activities.
Falls and mobility problems: Reduced strength, balance, and coordination that increase the risk of falls and related injuries such as fractures.
Osteoporosis: A condition in which bones lose mineral density and strength over time, increasing the risk of fractures, and closely linked to age-related hormonal and lifestyle changes.
Polypharmacy: The use of multiple medications at once, which becomes more common with age and raises the risk of drug interactions and side effects if not carefully managed.
Continence issues: Urinary or bowel incontinence, which can affect quality of life and is often under-reported, despite being manageable in many cases.
Frailty: A state of reduced physiological reserve and increased vulnerability to stressors such as illness, surgery, or minor injury.
Mood and sleep disorders: Depression, anxiety, and disturbed sleep, which can present differently in older adults and are sometimes mistaken for an inevitable part of ageing.
Multiple chronic conditions: Coexisting conditions such as diabetes, hypertension, and heart failure, which require coordinated rather than isolated management in older adults.

Recognising When to See a Geriatrician

Because ageing affects multiple body systems at once, the signs that an older adult may benefit from geriatric care can be varied and are sometimes overlooked as a normal part of getting older. Signs worth discussing with a doctor include:

Frequent or unexplained falls: Repeated falls, or a fall resulting in injury, can point to underlying issues with strength, balance, vision, or medication side effects.
Memory or thinking changes: Increasing forgetfulness, confusion, or difficulty managing everyday tasks that were previously straightforward.
Difficulty managing multiple medications: Confusion over dosing schedules, or side effects that may result from interactions between several medications.
Unexplained weight loss or poor appetite: A decline in nutritional status, which can be an early sign of an underlying medical, dental, or social issue.
Reduced mobility or physical function: A noticeable decline in the ability to walk, climb stairs, or carry out daily activities independently.
New or worsening continence problems: Increasing difficulty with bladder or bowel control.
Low mood, withdrawal, or sleep changes: Persistent low mood, loss of interest in usual activities, or significant changes in sleep patterns.

Risk Factors Addressed in Geriatric Care

Advanced age: The likelihood of frailty, falls, dementia, and multiple coexisting conditions increases with age, particularly from the mid-60s onward.
Multiple chronic conditions: Having several long-term conditions at once increases the complexity of care and the risk of complications.
Polypharmacy: Taking several medications simultaneously raises the risk of interactions and adverse effects.
Reduced physical activity: Inactivity accelerates the loss of muscle strength and mobility, increasing the risk of frailty and falls.
Social isolation: Living alone or having limited social support can affect both mental health and the ability to manage health conditions safely.
Prior falls or hospitalisations: A history of falls or recent hospital admission increases the likelihood of further decline without targeted support.
Sensory impairment: Declining vision or hearing can contribute to falls, social withdrawal, and difficulty managing medications and appointments.

How Geriatricians Assess Older Adults

Geriatric medicine relies heavily on the Comprehensive Geriatric Assessment, a structured evaluation that looks well beyond a single presenting complaint:

Medical assessment: A review of existing diagnoses, symptoms, and how various conditions are interacting with one another.
Medication review: A detailed review of all prescribed and over-the-counter medications to identify unnecessary, duplicate, or interacting drugs.
Functional assessment: Evaluation of a patient's ability to carry out daily activities such as walking, dressing, and managing household tasks.
Cognitive assessment: Screening for memory and thinking problems, including early signs of dementia.
Nutritional assessment: Evaluation of dietary intake and weight trends to identify malnutrition risk.
Psychological assessment: Screening for depression, anxiety, and other mental health concerns.
Social assessment: A review of a patient's living situation, support network, and access to care, all of which affect health outcomes.

Treatment and Support Approaches

Geriatricians can help older adults manage their health conditions, improve their quality of life, and maintain their independence. They provide a range of services, including:

Comprehensive health assessments: To identify and address potential health problems before they become serious.
Medication management: To optimise medication use and reduce the risk of adverse drug reactions.
Nutrition counselling: To ensure adequate intake of nutrients and prevent malnutrition.
Fall prevention strategies: To reduce the risk of falls and related injuries.
Pain management: To help manage chronic pain in a manner appropriate for older adults.
Rehabilitation: To improve physical function and mobility following illness, injury, or surgery.
End-of-life care: To provide compassionate care and support during the final stages of life.
