Is type 2 diabetes safe in older adults?

Type 2 diabetes affects how the body uses insulin and can gradually raise blood glucose. In later life, the effects of treatment may be influenced by kidney function, appetite, memory, eyesight, mobility and other medicines. A plan that suits one older adult may not suit another.

Low blood glucose can cause sweating, shakiness, hunger, dizziness, confusion or unusual behaviour. High blood glucose may cause thirst, frequent urination, tiredness or blurred vision. Some older adults may notice few symptoms, so scheduled checks and attention from family or carers can help identify changes early.

Keep a current list of medicines and attend reviews that check glucose, kidney function, blood pressure, feet and vision. Ask whether each medicine remains appropriate if meals are missed, weight changes or illness occurs. Store medicines safely, use reminders if helpful and make sure a trusted person knows how to recognise low glucose and what action has been agreed.

Regular meals, suitable activity, hydration and foot care support day-to-day management. Do not stop diabetes medicine suddenly without medical advice. During vomiting, diarrhoea, fever or poor intake, contact the care team promptly because the plan may need temporary adjustment.

Seek urgent help for severe confusion, fainting, a seizure, inability to swallow, extreme drowsiness, chest pain or trouble breathing. Contact the diabetes team promptly for repeated low readings, persistent vomiting, dehydration, a foot wound, new vision change or glucose readings that remain outside the agreed range.

What glucose range is appropriate for my health and daily routine? Which symptoms suggest low glucose? Should medicines change during illness or missed meals? How often should my kidneys, feet and eyes be checked?
