A practical guide to managing type 2 diabetes

A diagnosis of type 2 diabetes can feel overwhelming, but with the right routines most people manage it well and live full, active lives. This guide covers the everyday essentials, from monitoring to foot care.

What is type 2 diabetes

Type 2 diabetes is a long-term condition where blood sugar levels are too high because the body does not make enough insulin or cannot use it effectively. Over time, high blood sugar can damage blood vessels, nerves and organs, which is why steady control matters.

Know your numbers

Regular blood glucose monitoring helps you understand how food, activity and medication affect you. Your doctor will set personal targets. A home glucometer and a supply of test strips make daily checks quick and simple. Keep a log and bring it to your reviews.

Eating well with diabetes

There is no single diabetes diet, but some principles help: choose high-fibre, slower-release carbohydrates, fill half your plate with vegetables, include lean protein, and watch portion sizes. Limit sugary drinks and ultra-processed snacks, which spike blood sugar quickly.

Staying active

Activity helps your body use insulin better. Aim for regular movement most days, combining walking or cycling with some resistance exercise. Even short walks after meals can blunt blood sugar spikes.

Taking your medication consistently

If you are prescribed medication, take it exactly as directed. Consistency matters more than perfection. Refill reminders and automatic deliveries help you avoid running out, which is one of the most common reasons control slips.

Looking after your feet and eyes

High blood sugar can reduce sensation in the feet and affect the eyes. Check your feet daily for cuts or blisters, wear well-fitting shoes, and attend your annual eye and foot screening appointments.

Sick-day rules

Illness can raise blood sugar even if you are eating less. Keep taking your medication unless told otherwise, stay hydrated, monitor more often, and know when to seek help.

When to contact your doctor

Get medical advice if your readings are persistently high or low, if you have symptoms such as excessive thirst, blurred vision or numbness, or if you are unwell and unsure how to manage your medication.
