At HIYOS GP Practice, we believe understanding diabetes is the first step toward effective management. In our ongoing series on diabetes, Dr Nik Sharma (GP) and Maria Da Cunha (Healthcare Assistant) explain the basics of type 2 diabetes, how it develops, and what early signs to watch for.
What is Type 2 Diabetes?
Diabetes is all about blood sugar (glucose), which our body uses as a primary source of energy. Maria explains:
“Glucose is like petrol for a car. We need it for energy and for the brain to function.”
After we eat, glucose enters the bloodstream, but it cannot enter cells without insulin, a hormone produced by the pancreas. Insulin acts like a “key,” unlocking cells so they can absorb glucose and use it for energy.
Over time, cells become resistant to insulin. This means glucose stays in the bloodstream longer, gradually building up.
Pre-Diabetes: The Early Warning
Before full-blown diabetes develops, many people enter a pre-diabetic stage, where blood sugar levels are higher than normal but not yet diabetic. Dr Nik explains:
“This is the best time to intervene with lifestyle changes to bring blood sugar back to normal levels.”
Early education and intervention can prevent or delay the onset of type 2 diabetes, making routine testing and awareness crucial.
Common Symptoms of Type 2 Diabetes
Many people may feel completely healthy and have no obvious symptoms. However, Dr Nik notes some signs that may appear:
- Increased thirst
- Frequent urination
- Unintentional weight loss
- Slow-healing wounds or infections
These occur because excess glucose in the blood affects water absorption and immune function.

Several lifestyle factors influence the risk of developing type 2 diabetes:
- Diet and meal timing: Planning meals helps prevent spikes in blood sugar
- Weight and BMI: A healthy BMI is under 25 (23 for South Asians)
- Waist circumference: Fat around the belly increases insulin resistance (Men: 94cm, Women: 80cm; South Asian men: 90cm)
- Sleep and stress: Poor sleep and high stress raise insulin resistance
- Exercise, alcohol, and smoking: All impact blood sugar control
Maria emphasizes that even small improvements, like reducing waist size by a few centimeters, can have a big impact on risk.

Early detection of type 2 diabetes allows patients to take control through diet, exercise, and lifestyle changes. Dr Nik and Maria stress that routine blood tests are often the first way diabetes is identified, especially for people with no symptoms.
“The earlier diabetes is detected, the better the outcomes. Planning and setting goals can help manage the condition effectively.”
