Health by age · 80 and over

Healthy after 80 protect independence and act early

After 80 the question shifts from what your tests show to what you can still do: walk, dress, eat, manage the day and see the people who matter.

The guides cover what protects that: using your legs, preventing falls, spotting frailty, weight loss and sudden confusion early, pruning medicines, eating and drinking safely, seeing and hearing well, a home that helps, and a circle of care set up before it is needed.

Sixteen one-page guides, written for elders and the families who look after them, each with a source for every number.

Sources are listed below: Indian ones where they exist (the India Ageing Report, the national blindness survey, 112, Elderline and the Supreme Court on living wills), WHO and international guidelines for the rest, labelled as such.

The evidence

What each guide stands on

Most health advice on WhatsApp has no source. Each claim here links to one, with the kind of evidence it is, so you can check it or show your doctor.

  1. India's oldest old
    The number of Indians aged 80 and over is projected to grow by about 279% between 2022 and 2050, against 134% for everyone over 60. Many of the very old will be widowed women who depend on others.
  2. What WHO checks after 60
    WHO's approach to care for older people starts from what a person can do (moving, eating, seeing, hearing, memory and mood) rather than a count of diseases, and builds the care plan from that.
  3. The chair-rise check
    WHO's ICOPE screening asks a person to stand up from a chair five times without using their arms. Taking longer than 14 seconds marks reduced mobility and calls for a fuller assessment.
  4. How much to move after 65
    150 to 300 minutes of moderate activity a week, muscle strengthening on 2 or more days, and varied activity that trains balance and strength on 3 or more days, to improve function and prevent falls. Those who cannot do this much should be as active as their abilities allow.
  5. Exercise and falls
    Across 59 trials in people over 60 living at home, exercise cut the rate of falls by about 23%. Programmes built on balance and functional exercise worked best.
  6. Falls worldwide
    Falls are the second leading cause of unintentional injury death worldwide, about 684,000 deaths a year, and adults over 60 suffer the greatest number of fatal falls.
  7. After a fall
    All older adults should get advice on preventing falls and staying active. Anyone at high risk, including after a fall, should have a full falls assessment and a plan built with them.
  8. What frailty means
    In the most widely used definition, a person is frail with 3 or more of: losing about 4.5 kg in a year without trying, exhaustion, weak grip, slow walking and low activity. One or two signs mark pre-frailty. Frailty predicted falls, disability, hospital stays and death.
    Fried et al., Frailty in older adults: evidence for a phenotype, J Gerontol 2001 Cohort study · 5,317 people aged 65+ No Indian study covers this.
  9. Bed rest and muscle
    Ten days of bed rest made healthy older adults, average age 67, lose about 1 kg of muscle from their legs.
  10. Protein
    Older people should get at least 1 g of protein per kg of body weight a day, adjusted for their health, activity and tolerance. People with kidney disease should follow their doctor's advice.
  11. How much to drink
    Older women should be offered at least 1.6 litres of drinks a day and older men at least 2 litres, unless a medical condition calls for a different amount. All older adults are at risk of drinking too little.
  12. Swallowing problems
    Older people with signs of a swallowing problem should be screened and assessed, and food and drink textures should be adapted to what they can swallow safely.
  13. Protein from food
    Get protein from food, such as dal and other pulses, milk and curd, eggs, fish or meat, rather than protein supplements.
  14. Delirium
    Delirium is a change in thinking and behaviour that starts over hours or days and can come and go. Some people become agitated; others become quiet, sleepy and withdrawn, which is easily missed. Age over 65 and dementia raise the risk, and 20 to 30% of people on medical wards have it.
  15. Emergency numbers
    112 is India's single emergency number. It brings together the older numbers, including 100 for police, 101 for fire and 108 for an ambulance.
  16. Medicines to review after 65
    An expert list of medicines older adults should usually avoid or use with care. It includes benzodiazepine and ‘Z-drug’ sleeping pills, which raise the risk of confusion, falls and fractures, and medicines that need a lower dose when the kidneys work less well.
    American Geriatrics Society, 2023 Updated Beers Criteria, J Am Geriatr Soc 2023 Expert criteria No Indian list covers this; brand names differ in India.
  17. Weight loss
    In adults over 65, losing 5% or more of body weight over 6 to 12 months without trying needs a doctor's assessment. Causes include cancer, depression, medicines, mouth and swallowing problems, and loneliness or low income. Sometimes no cause is found.
  18. Sight in India
    Among Indians aged 50 and over, cataract caused 66.2% of blindness, and about 93% of blindness was avoidable with existing treatment.
  19. Hearing, sight and memory
    Hearing loss and untreated vision loss are two of 14 changeable risk factors that together account for nearly half of dementia worldwide.
  20. A safer home
    Home safety assessment and changes reduced falls, most clearly in people at higher risk of falling and when an occupational therapist did the assessment.
  21. Staying connected
    Across 148 studies, people with stronger social ties had about 1.5 times the odds of survival, an effect comparable to well-known risks such as smoking.
  22. Living wills in India
    Since 2018 Indians can make an advance medical directive, or living will, saying which treatments they would not want if they cannot decide, and naming who should decide for them. In 2023 the Supreme Court simplified the process: it is signed before two witnesses and attested by a notary or gazetted officer.
  23. Elderline
    Elderline, 14567, is the national toll-free helpline for senior citizens, open 8 am to 8 pm every day. It gives information on care and services, guidance on pensions and legal matters, emotional support, and field help in cases of abuse or neglect.

Guidance changes as evidence grows. When it does, the guides and this list will be updated. Last updated .

How these are made

  • Guidelines, not headlines. Every number comes from a guideline, a national survey or a systematic review, linked above.
  • Written for Indian families. Indian emergency numbers and helplines, khichdi and dal, squat toilets, and the family members who do most of the caring.
  • Function before numbers. What a person can do matters as much as a test result. Targets and medicines stay with the doctor who knows them.
  • Nothing to sell. No clinic, no supplements, no product. Free to print and share.
Education, not medical advice General guidance, not a substitute for a doctor who knows you. Do not start, stop or change a medicine on your own, check with your doctor or physiotherapist before new exercise, and in an emergency call 112.
