Type 1 diabetes is where the pancreases produces little or no insulin. This means a person's blood glucose level can rise to a level that can kill them. People with Type 1 diabetes need insulin therapy - this involves several injections of insulin throughout the day. This makes sure that glucose is removed from the blood quickly once the food has been digested, stopping the level getting too high. As well as insulin therapy, people also need to think about limiting the intake of food rich in simple carbohydrates, e.g. sugars and taking regular exercise. Type 2 diabetes is where the person becomes resistant to their own insulin. This can also cause the blood glucose to rise to a dangerous level. Being overweight can increase the chance of developing Type 2 diabetes, as obesity is a major risk factor in the development of the disease. Type 2 diabetes can controlled by eating a carbohydrate-controlled diet and getting regular exercise.
