A condition that affects how your body uses energy in the form of glucose from food, diabetes can be successfully managed through proper self-monitoring, medication and lifestyle changes. People with diabetes have a high level of glucose in their blood, which can be caused by either too little insulin being produced by the pancreas or the body not accepting or using the insulin it produces, or a combination of both.
People with diabetes need to keep their blood sugar levels within a healthy range. Blood sugar levels are controlled through diet, physical activity and, for some people, a combination of medication and insulin injections.
Insulin is a hormone your cells need to store and use energy from food, and it is responsible for getting glucose into your cells. If you have diabetes, insulin is not able to do its job. Meaning, glucose is unable to get into your cells, which causes it to build up in your blood. High levels of glucose then circulate through your body, damaging cells along the way.
