Type 2 Diabetes
How type 2 diabetes develops, the signs to look for, and how food, movement and medicine help you manage it.
Start here: Type 2 Diabetes basics
Type 2 diabetes is a long-term condition in which the body doesn't use insulin well (insulin resistance) and, over time, may not make enough of it. Blood sugar (glucose) then stays higher than it should.
It is very common, often develops slowly, and many people have it for years without knowing. The good news: it can be managed — and in some people put into remission — with a combination of eating habits, physical activity, weight management and, when needed, medicine.
- Get tested if you have symptoms or risk factors such as family history, excess weight or high blood pressure.
- Know your numbers: HbA1c, fasting glucose, blood pressure and cholesterol.
- Build a care team — your doctor, a dietitian and, if available, a diabetes educator.

Ask the expert
Can type 2 diabetes go away?
Some people reach remission — normal blood sugar without diabetes medicines — usually after significant weight loss. It isn't a cure, so regular check-ups are still important.
Answered by Amara Okafor, MDDo I have to give up carbohydrates?
No. The type and amount of carbohydrate matter more than cutting it out. Fibre-rich carbs like beans, lentils, whole grains and vegetables are a good foundation.

Type 2 Diabetes FAQs
What HbA1c level means diabetes?
An HbA1c of 6.5% (48 mmol/mol) or higher on two tests usually indicates diabetes. 5.7–6.4% suggests prediabetes. Your doctor will confirm the diagnosis.
Is type 2 diabetes genetic?
Family history raises your risk, but lifestyle factors such as weight, activity and diet play a large role, which is why prevention is possible for many people.
