Insulin is a hormone made in the pancreas. It helps us move glucose (sugar) from our blood into our cells where it’s used for energy.
The carbohydrates we eat are broken down into sugar in our blood. They’re in starchy foods like bread, potatoes and rice as well as fruit, some dairy products and other sweet food.
In type 1 diabetes people don’t make any insulin. So, they need to take insulin by either injection or pump.
People with type 2 diabetes also may need insulin at some point of time because diabetes keeps changing and the oral medicines may not work very well as they were intended. Sometimes in type 2 they may only need it for a short time for particular reasons like pregnancy, severe illness, surgery or even to bring about a good control in case of very high sugars and it could be stopped afterwards.
