What blood sugar is
Your body breaks down most food into glucose (sugar), which travels in your blood to fuel your cells. A hormone called insulin helps move that glucose out of your blood and into your cells. When this system stops working well, sugar stays in your blood at higher levels than it should — and that's the core of type 2 diabetes.
Type 1 and type 2 are different
Type 1 diabetes is an autoimmune condition where the body stops producing insulin. Type 2 — by far the more common form — is where the body still makes insulin but doesn't use it effectively, often developing gradually over years. They're different conditions with different causes and treatments.
What raises your risk
Type 2 diabetes risk is influenced by things you can and can't change:
- Being above a healthy weight, particularly carrying it around the middle
- Low physical activity
- A diet high in processed foods and sugary drinks
- Family history
- Age
- High blood pressure or cholesterol
The good news is that many of these are modifiable. For many people, type 2 diabetes can be prevented or delayed with straightforward lifestyle change — and even after diagnosis, it can often be well managed.
Why it matters
Over time, high blood sugar can damage blood vessels and nerves, raising the risk of heart disease, kidney problems, eye damage, and foot complications. The key message is that these problems are largely preventable with early detection and good management — which is why checking matters even when you feel well.
What a check involves
Diabetes is usually picked up with a simple blood test — commonly a fasting blood glucose test or an HbA1c test, which reflects your average blood sugar over recent months. Your doctor interprets the result alongside your risk factors, not in isolation.
How it's managed
Management is always individualised and may include lifestyle change, weight management, medication, and regular monitoring. Treatment is a clinical decision made with your doctor — never something to self-prescribe. Many men do very well with consistent, modest changes rather than dramatic overhauls.
When to get checked
If you're over 40, carry weight around your middle, have a family history, or have noticed symptoms such as excess thirst, frequent urination, unexplained tiredness, or blurred vision, it's worth getting checked. Even with no symptoms, a routine check is simple and worthwhile. A no-cost suitability consultation is an easy way to start.
