Managing diet when there's diabetes and dementia

My wife has had diabetes for years, and now with dementia, she doesn't understand why she can't eat so many sweets, and sometimes she refuses insulin or the correct meals. I'm constantly on top of this and terrified of her blood sugar dropping. How do I balance the two?

Managing diabetes and dementia at the same time is a huge burden, and the fear of hypoglycaemia keeps us constantly on alert. It is possible to find balance without turning every meal into a battle.

Why it happens

The person stops understanding restrictions and recognising the signs of low blood sugar. Meal times, medication, and insulin require regularity, but dementia makes cooperation difficult. Overly strict glycaemic targets can, in fact, be dangerous at this stage.

Practical strategies

• Maintain regular meal and medication times.
• Offer safer sweet alternatives: fruit, yoghurt, sugar-free desserts.
• Always have what's needed to treat hypoglycaemia (sugar, juice) on hand.
• Simplify the medication regimen with the doctor whenever possible.
• Choose your battles: avoiding hypoglycaemia is usually a priority over very strict control.

What NOT to do

• Do not impose an overly restrictive diet that leads to refusal and conflict.
• Do not alter insulin or medication on your own.
• Do not ignore signs of sudden confusion, sweating, or tremors.

When to seek professional help

Talk to your GP or attending doctor to review goals and adjust medication to the reality of dementia. In case of sudden confusion, sweating, or loss of consciousness, immediately call 112 or NHS 111.
