Insulin is inserted through an injection, specifically into the fat layer under the skin. This is achieved using a needle and syringe or an insulin pen.
Injection Technique
The proper injection technique is crucial for ensuring that the insulin is absorbed correctly. Here’s a step-by-step guide based on the provided reference:
- Pinching the Skin: To ensure the injection goes into the subcutaneous fat and not into muscle, start by pinching the skin. This lifts the fat layer, making it easier to target.
- Angle of Injection:
- 45-Degree Angle: The reference specifies that you should insert the needle at a 45-degree angle. This is generally recommended for most people to reach the fat layer effectively.
- 90-Degree Angle: If your skin tissues are thicker, you might be able to inject straight up and down (at a 90-degree angle). However, it’s critical to consult with your healthcare provider before making this adjustment.
- Injection: Once the needle is inserted at the appropriate angle, depress the plunger of the syringe or insulin pen to inject the insulin.
Considerations for Injection Sites
It's important to rotate injection sites to avoid problems like lipohypertrophy (a build-up of fat under the skin). Common injection sites include:
- Abdomen (around the belly button, avoiding a 2-inch area around it)
- Thighs (front and outer areas)
- Upper arms (back of the arm)
- Buttocks (upper, outer parts)
Summary of Key Points
- Insulin is injected into the subcutaneous fat layer under the skin.
- A 45-degree angle is generally recommended, but a 90-degree angle may be suitable for individuals with thicker skin, with medical professional approval.
- Pinching the skin helps ensure the injection goes into the fat layer.
- Rotating injection sites is crucial to avoid complications.
