Diabetes: Giving Yourself an Insulin Shot

If you have type 1 diabetes—or if you have type 2 diabetes and other diabetes medicines are not controlling your blood sugar—you have to take insulin. If you have gestational diabetes, you may need to take insulin if diet and exercise have not been able to keep your blood sugar levels within your target range.

With little or no insulin, sugar (glucose) in the blood cannot enter your cells to be used for energy. As a result, the sugar in your blood rises above a safe level. When your blood sugar rises past about 180 mg/dL, your kidneys begin to release sugar into the urine, which can make you dehydrated. If you are dehydrated, your kidneys make less urine, which means your body can't get rid of extra sugar. This is when blood sugar levels rise.

Taking insulin can prevent the symptoms of high blood sugar and emergencies such as diabetic ketoacidosis (in type 1 diabetes) and hyperosmolar coma (in type 2 diabetes). Insulin also can help lower blood sugar, which can prevent serious and permanent complications from long-term high blood sugar.

The three most important elements of success in giving insulin injections are:

  • Making sure you have the right dose of insulin, especially if you are giving two types of insulin in the same syringe.
  • Practicing how to give your injection.
  • Storing the insulin properly so that each dose will work effectively.
