Caring for an older person with diabetes

Caring for an older person with diabetes often involves a mix of practical help, companionship and keeping an eye out for changes. Some people manage most tasks themselves; others need support with meals, appointments, medicines or checking their blood glucose. There is no single path or timetable. Ask the person what matters to them, and work with their health professional to make a plan that suits their health, abilities and preferences.

What care may look like over time

Diabetes care does not follow a predictable set of stages. An older person’s needs may stay steady for a long time, change gradually or shift quickly after an illness, fall or hospital stay. Diabetes can also exist alongside other health conditions, changes in memory, vision or movement, and different levels of family support. The World Health Organization describes diabetes as a chronic condition that requires ongoing care; the details of that care should be individualised (WHO: Diabetes).

When needs are stable, the person may mainly want help organising appointments, getting groceries or keeping to a routine. Ask before taking over tasks they can and want to do themselves. Agree together on what support is welcome and how to review the arrangement.

When more help is needed, everyday tasks may become harder. For example, the person may have trouble remembering appointments, preparing meals, reading instructions or getting around safely. Offer specific choices rather than assuming what they need. A clinician can review the care plan if the person’s health, abilities or daily circumstances have changed.

During illness or after a hospital stay, routines and care needs can change. Ask the care team for clear instructions before the person returns home, including whom to call with questions and what to do if they are unwell. Do not change diabetes medicines or make treatment decisions on your own. If instructions are unclear or seem difficult to follow, contact the prescribing clinician or pharmacist.

Making everyday care manageable

A predictable, flexible routine can help without making the person’s day feel like a list of rules. With their agreement, you might:

• Coordinate meals, appointments and other daily activities around the person’s usual preferences.
• Keep the care team’s contact details and the current care plan somewhere easy for helpers to find.
• Help arrange transport or accompany the person to appointments, if they want that support.
• Write down questions and observations to discuss with the clinician.
• Check whether the person’s home setup makes daily tasks easier, including lighting, clear walkways and access to frequently used items.

Avoid imposing a special diet, restricting foods or making assumptions about what the person should eat. Ask the clinician or a qualified dietitian for guidance that takes account of the person’s health, culture, preferences and resources. If their appetite, eating habits or ability to prepare food changes, mention it to the care team.

If the person checks their blood glucose at home, follow the plan they were given. Help only with tasks they want or need help with, and do not interpret a reading or adjust care without appropriate guidance. A Carer's daily log generator can help family members record observations and questions; a blood glucose log may be useful if the care team has asked for readings to be recorded.

For medicines, follow the current instructions from the prescriber or pharmacist. Keep an up-to-date list of medicines and allergies, and ask the care team what to do if a dose is missed, the person cannot eat as usual or they become ill. Never guess at a dose or double a dose unless a qualified professional specifically tells you to.

Safety and warning signs

Some people with diabetes can have low blood glucose, especially if they use certain diabetes medicines. Signs can include sweating, shaking, hunger, dizziness, weakness, difficulty concentrating or confusion. These signs can have other causes too, and symptoms may be less obvious in an older person. Follow the person’s own care plan and seek advice from their clinician if episodes recur or you are unsure what is happening. The NHS explains signs of low blood sugar and when to get help (NHS: Low blood sugar).

If the person is unconscious, having a seizure or unable to swallow safely, treat it as an emergency. Call your local emergency number. Do not give food or drink to someone who is unconscious or unable to swallow.

High blood glucose can cause symptoms such as increased thirst, needing to urinate more often, tiredness or blurred vision. New or worsening symptoms should be discussed with a clinician. Seek urgent medical help if the person is very unwell, becomes unusually drowsy or confused, vomits repeatedly, or has deep or rapid breathing. Follow local emergency guidance and the person’s care plan rather than trying to manage a serious episode at home. The NHS also describes symptoms of high blood sugar (NHS: High blood sugar).

Contact the person’s clinician promptly if you notice a significant change in their usual health, repeated low or high readings, a new wound or sore, or a change in eating, drinking, vision, walking or memory. Ask in advance whom to call outside normal clinic hours. If a change is sudden or severe, use local emergency services.

Working with the care team

The person’s care team may include a GP, diabetes specialist, nurse, pharmacist, dietitian or foot-care professional, depending on local services and individual needs. The older person should be included in decisions as much as they wish and are able. If they agree, ask whether you may join appointments or receive care information.

Useful questions include:

• What are the main goals of the current diabetes plan?
• Which symptoms should prompt a call, and which require emergency help?
• What should we do if the person is unwell, eating less or unable to follow their usual routine?
• Who should we contact with questions about medicines or home monitoring?
• Are there changes in mobility, eyesight, memory or daily living that should affect the plan?

Keep notes brief and factual: what changed, when it happened, what the person said, and what action you took. A care team contact list can keep key numbers together. A home safety checklist for older people can help your family review practical risks around the home without treating every hazard as a crisis.

Looking after yourself as a carer

Supporting someone over time can be tiring, especially when family members have different schedules or live far apart. Decide which tasks you can reliably take on, and ask others to take on specific jobs—such as transport, shopping or attending an appointment. A shared plan can reduce repeated messages and make gaps in support easier to notice.

You do not have to be available every hour to be a caring family member. Make room for sleep, work, relationships and activities that help you recover. If you feel persistently overwhelmed, isolated or unable to manage your responsibilities, talk with someone you trust and ask a local health or community service about carer support or respite options. Seek help early when the arrangement is no longer manageable.

Good care is not about doing everything yourself. It is about respecting the older person’s choices, knowing when to ask for professional guidance and building a practical circle of support around both of you.
