Type 1 diabetes is a lifelong disease that develops when the pancreas stops making insulin. The body needs insulin to let sugar (glucose) move from the blood into the body's cells, where it can be used for energy or stored for later use.
Without insulin, the sugar cannot get into the cells to do its work. It stays in the blood instead. This can cause high blood sugar levels. A person has diabetes when the blood sugar is too high. Over time, diabetes can lead to diseases of the heart, blood vessels, nerves, kidneys, and eyes.
To treat type 1 diabetes, you need insulin. You can give yourself insulin through an insulin pump, an insulin pen, or a syringe (needle). Insulin, exercise, and a healthy diet can help prevent or delay problems from diabetes.
With education and support, you will treat diabetes as a part of your life—not your whole life. Seek support when you need it from your family, friends, and your doctor or other diabetes experts.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
Call 911 anytime you think you may need emergency care. For example, call if:
