When you have type 2 diabetes, your blood glucose (sugar) levels are higher than normal. Blood glucose comes mainly from the food you eat, and some is produced by your liver. Your body uses glucose for energy with the help of insulin, a hormone made by your pancreas. You can develop type 2 diabetes when your body
• doesn’t make enough insulin
• doesn’t use insulin the way it should, a condition called insulin resistance
Most people with type 2 diabetes have both problems. Middle-aged and older people are more likely to develop type 2 diabetes. So are people who are overweight (especially around the waist) and physically inactive.
