Hypoglycaemia (low blood glucose, or “hypo”) can happen at any age for people living with diabetes, but it carries special risks for older adults. Changes in appetite, memory, and other health conditions mean that hypos can be both harder to recognise and more dangerous as we age.
Why Hypos Are Riskier in the Elderly
- Reduced awareness: Older adults may not feel the early warning signs of a hypo as clearly as younger people, due to the effects of ageing and some medications.
- Other health conditions: Heart disease, kidney disease, or dementia can make hypos more serious or mask their symptoms.
- Falls and injuries: A hypo can lead to dizziness or confusion, increasing the risk of falls, which can have major consequences in older age. A hypo can also result in a heart attack in older adults.
- Medication interactions: Multiple prescriptions (“polypharmacy”) may interfere with blood glucose control, and blood pressure medications called beta blockers can mask symptoms.
Subtle Signs to Watch For
Hypos in older adults don’t always look the same. Instead of shakiness or sweating, symptoms may include:
- Confusion or forgetfulness
- Looking vague
- Slurred speech
- Drowsiness or sudden fatigue
- Personality or mood changes
- Unsteadiness or falls
Supporting Safe Diabetes Care in Older Adults
- Encourage regular blood glucose monitoring, especially before and two hours after meals.
- Ensure easy access to hypo treatments in the home and when out.
- Involve family, carers, and aged care staff in recognising signs and responding quickly.
- Review medications regularly with a health professional to simplify regimens and reduce hypo risk.
Hypos in older adults can be subtle but serious. By monitoring carefully, and supporting independence with the right routines, families and carers can help older people with diabetes stay safe and confident.
