Insulin for People with Type 2 Diabetes

Insulin is a hormone produced by your pancreas. Often referred to as the “most powerful” hormone in the human body, we all need insulin to live. Without enough insulin, your body cannot use the sugar (glucose) in your bloodstream for fuel. Without enough insulin, the amount of sugar in your bloodstream can rise to above-normal levels that threaten your short-term and long-term health.

In people with type 2 diabetes, your body is struggling with two things that can lead to high blood sugar levels:

• Insulin resistance: This is when your body isn’t responding to normal amounts of insulin and isn’t able to use that insulin effectively to manage your blood sugar levels. Some insulin resistance can be improved through lifestyle changes (like physical activity and weight-loss). For some people, insulin resistance is a deeper issue that cannot always be easily changed. This means you may need support from diabetes medications or insulin to help you manage healthy blood sugar levels.
• Beta-cell dysfunction: This is when your body struggles to produce normal amounts of insulin. Beta-cells are produced by the pancreas, then those cells produce insulin. In many people with type 2 diabetes, your body struggles to produce normally functioning beta-cells which means you don’t produce enough insulin. This can worsen over time, and your body is able to produce less and less insulin over time. This means you’ll need more support from diabetes medications or insulin to help you manage healthy blood sugar levels.

After being diagnosed with type 2 diabetes, your doctor will likely prescribe the oral medication metformin first. You’ll also be encouraged to make changes in your food and exercise habits. However, because many people with type 2 diabetes experience gradual beta-cell dysfunction, insulin may eventually be the best medication to help you manage safe and healthy blood sugar levels.

It’s okay if you need insulin!

There is a great deal of shame and guilt that can come with needing insulin as a person with type 2 diabetes. It’s important to note that starting insulin is never the fault of the person with diabetes and that this treatment is to help improve or maintain a high quality of life. Beginning an insulin regimen to manage or improve your blood sugar levels does not mean you have “failed” at diabetes management.

It simply means your body needs insulin to help you manage healthy blood sugar levels.

Today, there are so many types of support and technology to help you live well with diabetes, including long-acting and rapid-acting insulin, inhaled insulin, continuous glucose monitors that check your blood sugar without daily finger pricks, smart insulin pens and insulin pumps!
