What is Type 2 Diabetes?

Diabetes UK

Type 2 diabetes is a serious condition where the insulin your pancreas makes can’t work properly, or your pancreas can’t make enough insulin. This means your blood glucose (sugar) levels keep rising.

What causes type 2 diabetes?

We all need insulin to live. It does an essential job. It allows the glucose in our blood to enter our cells and fuel our bodies.

When you have type 2 diabetes, your body still breaks down carbohydrate from your food and drink and turns it into glucose. The pancreas then responds to this by releasing insulin. But because this insulin can’t work properly, your blood sugar levels keep rising. This means more insulin is released.

For some people with type 2 diabetes this can eventually tire the pancreas out, meaning their body makes less and less insulin. This can lead to even higher blood sugar levels and mean you are at risk of hyperglycaemia.

Is type 2 diabetes serious?

Around 90% of people with diabetes in the UK have type 2. It is serious condition and can be lifelong.

If left untreated, high sugar levels in your blood can seriously damage parts of your body, including your eyes, heart and feet. These are called the complications of diabetes. But with the right treatment and care, you can live well with type 2 diabetes and reduce your risk of developing them. Learn more about diabetes complications.

Can type 2 diabetes be cured?

There is no cure for type 2 diabetes, but some people are able to put their diabetes into remission. This means that your blood sugar levels are healthy and you don’t need to take diabetes medication any more. Remission can be life-changing, but it’s not possible for everyone.

Signs and symptoms of type 2 diabetes

When you have type 2 diabetes your body can’t get enough glucose into your cells, so a common symptom is feeling very tired. There are also other symptoms to look out for. These include feeling thirsty, going to the toilet a lot and losing weight without trying to.

The symptoms of type 2 diabetes can develop more slowly than the symptoms of type 1 diabetes, making the condition harder to spot. That’s why a lot of people don’t get any symptoms, or don’t notice them.

Some people also don’t think the symptoms are important, so don’t ask for help. This means some people can live for up to 10 years with type 2 diabetes before being diagnosed. Learn more about the symptoms of diabetes.

Risk factors of type 2 diabetes

  • your ethnicity
  • high blood pressure
