How is type 2 diabetes different in older adults?

Age itself does not define one treatment plan. Kidney function, heart disease, frailty, eyesight, hearing, memory and the medicines already being taken can change choices. Some older adults have few symptoms, while others notice thirst, frequent urination, tiredness, blurred vision or unplanned weight change.

Low blood sugar can be especially concerning when meals are missed, appetite is poor, or medicines continue during illness. A low reading may cause sweating, shakiness, confusion, unusual behaviour or weakness, and symptoms can be mistaken for another problem.

Keep a current list of medicines and supplements, and record glucose readings alongside meals, activity and symptoms. Ask the diabetes team whether targets or doses should change when eating patterns, kidney function or daily support changes.

Regular meals suited to your health needs, safe movement, foot checks and routine eye and kidney assessments support day-to-day care. A family member or carer may help with reminders, but the plan should preserve the person’s choices and independence where possible.

Seek urgent medical help for severe confusion, fainting, a seizure, inability to swallow, repeated vomiting, difficult breathing or marked drowsiness. Contact a clinician promptly for repeated low readings, persistent high readings, dehydration, a new foot wound or sudden change in alertness.

Ask which glucose range is appropriate for your overall health, what to do when meals are missed, how medicines should be adjusted during illness, and who should help with monitoring if memory or eyesight is changing.
