Frequently Asked Questions (FAQs)
1. How does an insulin injector work?
It works by helping move sugar from the blood into other body tissues where it is used for energy. It also stops the liver from producing more sugar. All of the types of insulin that are available work in this way.
2. What devices can be used to administer insulin?
There are different ways to inject insulin into your body; this is called insulin delivery. Syringes, pens, pumps, and jet injectors give many persons with diabetes options for their insulin delivery. A syringe is a device with a hollow center, plunger, needle, and removable needle guard.
3. Do jet injectors hurt?
Injections given by jet injectors are claimed to be relatively pain-free, and in several studies this method was favoured in comparison with injections given in the conventional way by syringe and needle.
4. What needle do you use for insulin?
Traditionally, needles used in insulin therapy were 12.7 millimeters (mm) in length. Recent research shows that smaller 8 mm, 6 mm, and 4 mm needles are just as effective, regardless of body mass. This means insulin injection is less painful than it was in the past.
