It's very important to take your diabetes medications as recommended by your doctor. Left untreated, diabetes can lead to serious, even life-threatening complications. Complications can lead to loss of vital body functions (such as with your kidneys), blindness, the need for amputation of toes or feet, and even death (especially from cardiovascular disease). By taking your medications as recommended, you greatly reduce your risk of developing diabetes-related complications.
Treatment includes changes in lifestyle (diet and exercise), plus medicine (if needed). Diabetes can be treated with oral medicines (pills), insulin, and/or other injected medicines. People with type 1 diabetes always need insulin. People with type 2 diabetes usually need treatment with oral medicines for several or even many years, but may eventually need insulin to maintain glucose control.
