Diabetes: How to Inject Insulin | NHS

Introduction to Insulin Injections

For individuals diagnosed with diabetes, especially type 1 diabetes, insulin injections are an essential part of managing blood glucose levels. The NHS provides guidelines to ensure that patients in the UK administer insulin correctly and safely. Proper technique can improve insulin absorption and maintain blood sugar control, thereby enhancing overall health and wellness.

Preparing for an Insulin Injection

Before injecting insulin, it's important to gather all necessary supplies: insulin pen or syringe, insulin vial, an alcohol swab, and a sharps disposal container. Wash your hands thoroughly with soap and water to prevent any infection. Next, if you are using a new insulin vial, gently roll it between your hands to mix the insulin. Always check the expiration date and inspect the insulin for any cloudiness or particles if it's supposed to be clear.

Choosing the Injection Site

Insulin can be injected into the fatty tissue just under the skin. Common injection sites include the abdomen, thighs, buttocks, and upper arms. Rotating your injection sites is crucial to prevent lipodystrophy (lumpiness or scarring of fatty tissue). For example, if you inject into your abdomen for one injection, consider using your outer thigh for the next.

Administering the Insulin

1. **Clean the Injection Site:** Use an alcohol swab to clean the chosen area. Let the alcohol dry to prevent stinging. 2. **Prepare the Insulin:** If you are using an insulin pen, attach a new, sterile needle. Prime the pen by dialing up a small dose (usually 2 units) and pressing the plunger to expel air bubbles. 3. **Inject the Insulin:** Pinch the skin lightly, and insert the needle at a 90-degree angle if the needle is short (4-6 mm). For longer needles, you may need to insert at a 45-degree angle to avoid injecting into the muscle. 4. **Deliver the Dose:** Press the plunger or the button on the pen fully until the dose is completely delivered. Hold the needle in place for about 10 seconds to ensure all the insulin has been injected. 5. **Withdraw the Needle:** Remove the needle and gently apply pressure to the injection site with a swab for a few seconds.

After the Injection

Dispose of the used needle and syringe or pen needle in a designated sharps disposal container. Do not throw these items in the household waste to avoid injury and contamination. Monitor your blood glucose levels regularly as per your GP’s recommendations and adjust your insulin dosage if advised.

Conclusion

Injecting insulin can seem daunting, but with practice and adherence to NHS guidelines, it becomes a routine part of diabetes management. If you have any concerns or experience complications, contact your healthcare provider for advice. Proper insulin administration helps keep diabetes under control, leading to a healthier and more active life.
