When we hear the word diabetes, many of us immediately think:
🍰 Too much sugar.
🍫 Too many sweets.
🥤 Too many fizzy drinks.
But type 2 diabetes isn’t simply a case of eating too much sugar.
Yes, type 2 diabetes results in too much glucose in the bloodstream, but to understand why, we need to talk about INSULIN and INSULIN RESISTANCE.
WHAT DOES INSULIN ACTUALLY DO?
Insulin is a hormone produced by the pancreas.
Think of insulin as a key.
After we eat carbohydrates, they are broken down into glucose. Insulin helps that glucose move from our bloodstream into our cells, where it can be used for energy.
But what happens when that system stops working efficiently?
WHAT IS INSULIN RESISTANCE?
Insulin resistance occurs when the body’s cells don’t respond to insulin as effectively as they should.
The pancreas may initially compensate by producing more insulin to help maintain normal blood glucose levels.
For some people, this can continue for some time.
Eventually, however, the pancreas may no longer be able to produce enough insulin to overcome that resistance.
Blood glucose begins to rise.
- Prediabetes may develop.
- Eventually, this can progress to type 2 diabetes.
And here’s the important part:
Insulin resistance and prediabetes can exist without obvious symptoms.
You may feel perfectly well.
So, what should you look out for?
As blood glucose becomes elevated, possible symptoms of type 2 diabetes include:
🔹 Feeling unusually thirsty
🔹 Urinating more frequently — particularly at night
🔹 Feeling unusually tired
🔹 Blurred vision
🔹 Cuts or wounds taking longer to heal
🔹 Recurrent thrush or genital itching
🔹 Losing weight without trying
But some people with type 2 diabetes have few or no noticeable symptoms, particularly during its earlier stages.
But surely sugar still matters?
Yes, but the relationship is more complicated than “sugar causes diabetes.”
Eating sugar does not directly mean that you will develop type 2 diabetes.
Risk is influenced by a combination of factors including:
🧬 Genetics and family history
⚖️ Body weight and waist measurement
🏃 Physical activity
🥗 Overall diet
🎂 Age
🩺 Other metabolic and health factors
🌍 Ethnic background
Regularly consuming high-calorie foods and sugar-sweetened drinks can contribute to excess energy intake and weight gain, which can increase the risk of developing type 2 diabetes.
So this isn’t about pretending sugar doesn’t matter.
It’s about understanding that type 2 diabetes is far more complex than sugar alone.
🩺 Don’t just wait for symptoms!
Type 2 diabetes can remain undiagnosed for years.
If you have symptoms, a family history or other risk factors, speak to your GP or healthcare professional about your individual risk and whether you should have a blood test.
Because proactive healthcare isn’t just about treating disease.
It’s about understanding your body before disease has the opportunity to take hold.
