Quick read
Key points
- 1
Diabetes is a long-term condition in which the body cannot properly regulate blood sugar levels, either because the pancreas doesn't produce enough insulin (type 1) or because the body doesn't use insulin effectively (type 2). Left unmanaged, high blood sugar can affect the eyes, kidneys, nerves, and heart, but with good management, most people with diabetes live full, healthy lives.

What is Diabetes?
Diabetes is a long-term condition in which the body cannot properly regulate blood sugar levels, either because the pancreas doesn't produce enough insulin (type 1) or because the body doesn't use insulin effectively (type 2). Left unmanaged, high blood sugar can affect the eyes, kidneys, nerves, and heart, but with good management, most people with diabetes live full, healthy lives.
Type 1 diabetes usually develops in childhood or young adulthood and always requires insulin treatment, while type 2 diabetes is more common in adults and is often managed with lifestyle changes, tablets, and sometimes insulin, depending on the individual.
02 · Understand
Clinical context
Both types need consistent, ongoing management
Whether type 1 or type 2, consistent blood sugar monitoring and treatment, along with regular check-ups for eyes, kidneys, and feet, are central to preventing long-term complications.
03 · Act
When to Seek Care
- 1You have symptoms like excessive thirst, frequent urination, or unexplained weight loss
- 2You have risk factors for type 2 diabetes and would like to be tested
- 3You've been diagnosed and have questions about your treatment plan
- 4You notice signs of very high or very low blood sugar — seek urgent care for severe symptoms

Practical steps
Regular Monitoring and Check-Ups Prevent Long-Term Complications
Consistent blood sugar management, alongside regular eye, kidney, and foot checks, significantly reduces the risk of diabetes-related complications over time.
- 1Monitor blood sugar as recommended.Follow your care team's specific guidance on testing frequency and targets.
- 2Take medication or insulin consistently.This is central to keeping blood sugar within a healthy range.
- 3Maintain a balanced diet and regular activity.Both play an important role in blood sugar control, particularly for type 2 diabetes.
- 4Attend regular screening appointments.This includes Diabetic RetinaScreen for your eyes, and regular checks for your kidneys and feet.
- 5Know the signs of high and low blood sugar.Recognising these early helps you respond appropriately and avoid emergencies.
