Here are five subtle warning signs that deserve attention.
1. Unintentional Weight Loss and Loss of Appetite
A gradual decrease in appetite is common with advancing age, but significant or ongoing weight loss may indicate a more serious problem.
Signs include:
- Eating much smaller portions than usual.
- Losing interest in favourite foods.
- Clothes or jewellery becoming noticeably looser.
- Increased weakness due to poor nutrition.
Possible causes:
- Heart, lung, kidney, or liver disease.
- Cancer.
- Dementia.
- Difficulty swallowing.
- Depression.
- Frailty.
If an older adult loses around 5% or more of their body weight over 6–12 months without trying, they should be evaluated by a healthcare professional.
2. Increasing Fatigue and Sleeping Much More
Many people become slightly less energetic with age, but persistent exhaustion that limits daily activities can be a sign of declining health.
Warning signs include:
- Sleeping most of the day.
- Becoming exhausted after minimal activity.
- Needing frequent naps.
- Having difficulty staying awake during conversations.
Potential reasons include:
- Progressive heart failure.
- Advanced lung disease.
- Anaemia.
- Kidney disease.
- General physical decline.
As people approach the end of life—particularly in the final weeks or days—they often spend much more time asleep.
3. Declining Mobility and Frequent Falls
Loss of physical function is one of the strongest indicators of overall health decline.
Look for:
- Difficulty walking even short distances.
- Needing increasing assistance to get out of bed or a chair.
- Repeated falls.
- Loss of balance.
- Spending most of the day sitting or lying down.
This may reflect:
- Muscle loss (sarcopenia).
- Frailty.
- Neurological conditions.
- Worsening chronic disease.
Reduced mobility also increases the risk of infections, pressure injuries, and hospital admissions.
4. Withdrawal from Social Activities
People experiencing declining health often become less interested in social interaction.
Possible signs:
- Declining invitations.
- Talking less than usual.
- Losing interest in hobbies.
- Spending long periods alone.
- Reduced emotional engagement.
This can be caused by:
- Depression.
- Dementia.
- Chronic pain.
- Fatigue.
- Physical limitations.
While social withdrawal alone does not indicate the end of life, combined with other physical changes it may suggest significant decline.
5. Repeated Hospitalisations or Worsening Chronic Illness
One of the clearest indicators that someone may be entering the final year of life is a pattern of worsening medical problems.
Examples include:
- Multiple emergency hospital visits.
- Frequent infections, such as pneumonia or urinary tract infections.
- Worsening heart failure or chronic lung disease.
- Increasing dependence on others for everyday tasks.
- Reduced recovery after illnesses.
Doctors sometimes use this overall pattern—not a single symptom—to identify people who may benefit from palliative care, which focuses on comfort, symptom management, and quality of life alongside other treatments.
Other Changes That May Occur
Some people also experience:
- Increasing confusion or memory problems.
- Difficulty swallowing.
- Breathlessness with little activity.
- Persistent pain.
- New urinary or bowel incontinence.
- Fragile skin and slower healing.
- Greater need for assistance with washing, dressing, and eating.
These symptoms are not specific to the last year of life and should be assessed, as many are treatable.
When to Seek Medical Advice
Arrange a medical review if an older adult has:
- Significant unexplained weight loss.
- Repeated falls.
- Persistent extreme fatigue.
- Rapid decline in mobility.
- Frequent hospital admissions.
- New confusion or marked changes in thinking.
- Difficulty eating or swallowing.
Urgent medical attention is needed for symptoms such as severe chest pain, sudden weakness on one side of the body, severe shortness of breath, or loss of consciousness.
An Important Perspective
Many people who experience one or more of these signs live for several years, especially when underlying conditions are identified and treated. Likewise, some people who appear relatively well may experience an unexpected decline. Predicting life expectancy is difficult, so healthcare professionals consider the overall pattern of physical function, medical conditions, and changes over time rather than relying on any single symptom.
If you’re concerned about a specific elderly person, sharing their age, medical conditions, and the changes you’ve noticed can help provide more tailored information about what those changes might mean.
