1. Why do I need insulin?
Insulin allows glucose to move into cells to be stored in the body as energy (fuel). Blood glucose levels will build up when there is insufficient insulin produced or when your body is unable to use insulin properly. This will lead to diabetes related complications in the long term.
Insulin is crucial for patients with type 1 diabetes.
If you have type 2 diabetes, insulin may be needed if lifestyle and diet measures cannot control your glucose levels, or if you have conditions that make other oral medications unsuitable.
Insulin is the safest option in controlling blood glucose level during pregnancy.
2. Does being on insulin mean that I am going to die?
This is NOT TRUE.
Many patients have the misconception that their health is deteriorating when they are advised to take insulin.
At certain stages of the disease, insulin becomes necessary to bring glucose levels back to control.
Insulin is there to improve your health, not take it away!
3. Does insulin make me hungry and put on weight?
It is true that insulin can lead to weight gain. Hence, it is important to control your diet and maintain an active lifestyle.
Discuss with you doctor if you have concerns with weight gain.
4. How many types of Insulin are available?
A) Slow-acting (basal insulin):
Acts slowly throughout the day, lasting up to 24 hours.
B) Fast-acting (meal-time insulin):
Acts quickly to control the rise in blood glucose after food. This type of insulin
must be taken together with food.
You should not take it if you are going to skip your meals.
Figure 1. The above diagram shows the different actions of fast and slow acting insulin.
5. Should I choose insulin in a glass bottle or in a pen?
The following may be able to help you make your choice.
If any of the statements below describe you, a pen insulin may be more suitable.
My daily routine is not regular.
My meal timings are irregular.
I often travel overseas.
I often experience low glucose levels (hypoglycaemia).
6. Can I just Inject insulin once a day?
Slow-acting (basal insulin) can sometimes be injected once a day.
Fasting-acting (meal-time insulin) is usually injected between one to three times a day.
Speak to your doctor to discuss which type of insulin suits you.
7. Why are my insulin doses different from other patients?
The dose of insulin is dependent on each person's body weight, diet, exercise, lifestyle, use of other medications and existing medical conditions.
Take note and follow your prescribed insulin doses.
