Medicines and treatments for type 1 diabetes
In addition to dietary changes and physical activity, people with type 1 diabetes will always need to use injected insulin to control their blood sugar levels, since their body produces little or no insulin.
Controlling diabetes with insulin is essential
There are three main reasons to treat type 1 diabetes with insulin:
- to relieve the symptoms of type 1 diabetes, including increased thirst and needing to urinate frequently
- to keep blood glucose as close as possible to recommended levels (i.e. 6.1–8.0 millimoles [mmol] per litre [L] before a meal and 6.0–10.0 mmol/L after a meal) to avoid ‘hypos’ (hypoglycaemia)
- to reduce the risk of developing the complications of diabetes, such as heart disease, kidney disease, eye conditions, and foot and leg problems.
People with type 1 diabetes may use different types and forms of insulin and the dose will vary according to their individual needs. The type, form and dose of insulin may need to change during pregnancy and illness, or before and after surgery.
If you would like to find out more, read our detailed medicines information about insulin.
Anyone with type 1 diabetes should also follow a healthy, balanced diet and be physically active. This can help to maintain a healthy weight and may improve blood glucose control, reduce the need for medicines, and help to prevent some of the long-term complications of diabetes.
Some people will need to take other medicines to manage their diabetes-related health problems (e.g. high blood pressure or high cholesterol) in addition to using injected insulin and following a healthy diet, quitting smoking, and undertaking regular physical activity.
It is important for people to tell their health professional about all the medicines they are taking — prescription, over-the-counter and complementary (herbal/‘natural’/vitamin/mineral) medicines — as some medicines may interact with insulin and affect blood glucose control.
