Insulin treatment for type 1 diabetes
What is insulin treatment?
People with type 1 diabetes need daily injections of insulin to survive. Insulin treatment aims to get as close as possible to the natural insulin response of someone without diabetes. This can help people with type 1 diabetes keep a balance of the right amount of insulin to maintain balanced blood glucose levels, which is important to stay healthy and avoid damage to health later in life.
How insulin works
Types of insulin treatment
There are several types of insulin treatment available for type 1 diabetes. Speak to your diabetes team to discuss available treatment options to tailor your diabetes treatment to your specific needs and preferences.
Long-acting (basal) insulin
Basal insulin treatment aims to match the constant, steady release of insulin in someone without diabetes. It keeps a low, consistent level of insulin in your blood over an extended time to keep your blood glucose levels steady throughout the entire day, including between meals and when you sleep.
It is important that basal insulin gets close to a natural insulin response as too much or too little insulin can cause hypoglycaemia (low blood glucose) or hyperglycaemia (high blood glucose), respectively.
Your blood glucose rises rapidly after eating and sometimes basal insulin treatment isn't enough to control these 'spikes'. Mealtime, also called bolus, insulin treatment aims to bring down such spikes in blood glucose that can occur after eating. The closer that mealtime insulin treatment can get to the insulin response in someone without diabetes, the quicker it may be able to bring down these spikes.
Ways to take insulin treatment
Many people take insulin by injection with insulin pens. There is a wide range of pens and needles available for insulin injections depending on your requirements. These have been designed to be ultra-discreet and easy to use.
They can be pre-filled and disposable or refillable and durable. Some have a memory function and/or require only a very small pressure to operate them, making them suitable for many users, including children as young as 1 year old as well as the elderly population.
Some people with type 1 diabetes take their insulin using a small, computerized device called an insulin pump. Insulin pumps provide the body with insulin throughout the day. The idea is that instead of delivering separate injections during the day, an insulin pump releases insulin gradually over the course of the day, just like your body would naturally. This means a pump substitutes for continuous, or basal insulin. When it’s time for a meal, the pump also delivers variable amounts of insulin when a meal is eaten (bolus insulin).
An insulin pump is essentially made up of two parts (which are connected by a small, flexible tube):
- A reservoir which holds the insulin
- A needle which sits under the skin
The insulin pump is fitted onto a person’s lower abdomen and held in place with an adhesive patch, or worn in a belt around the waist, armband, bra or other accessory. The average pump is about the size of a pack of cards. It has a digital display screen and buttons for programming.
There are lots of different types of insulin pumps available with different features. For example, some of the more modern pumps have touchscreens, or can connect wirelessly to a glucometer. Your doctor will be able to help you select a model that’s best suited to your needs and lifestyle.
