Blood sugar & nerves

The connection

Over time, high blood sugar can damage the small blood vessels that supply the nerves and affect the nerves directly. This is why nerve problems are one of the most common long-term complications of diabetes, and why keeping blood sugar in a healthy range is a central part of protecting nerves.

Know your numbers

Many people with raised blood sugar do not know it. A simple blood test at a routine check-up can show your average levels over the past few months. If you already have diabetes, your care team will agree personal targets with you.

Everyday habits that help

• Regular meals built around vegetables, protein, and fibre.
• A short walk after meals.
• Swapping sugary drinks for water.
• Enough sleep and ways to manage stress, which both affect blood sugar.
• Taking prescribed medicines as directed and attending regular reviews, including foot checks.
