Giving an insulin injection to an adult with diabetes
Why give insulin?
Normally, insulin is produced by the pancreas. Insulin lets sugar (glucose) in the blood enter body cells, where it is used for energy. It helps the body store extra sugar in muscles, fat, and liver cells. Later, that sugar can be released if it is needed. Without insulin, the body cells cannot use sugar, causing the blood sugar level to rise above what is safe for your body.
You need to take insulin because you have:
- Type 1 diabetes, which causes your body to produce little or no insulin. You have to take one or more types of insulin for the rest of your life.
- Type 2 diabetes, which causes your body to require more insulin than it can produce. When your body starts producing too little or no insulin, you will have to take insulin for the rest of your life. You may need to take insulin for a short time if your body is under unusual stress, such as if you are having major surgery, are severely ill, or become pregnant.
- Gestational diabetes. Your body is not able to use insulin properly. You will need to take insulin during your pregnancy if getting regular exercise and eating a balanced diet does not keep your blood sugar levels within your target range.
