Insulin - Type 2 Diabetes Medication

Many different types of medications are available to help lower blood sugar levels in type 2 diabetes. Your doctor will prescribe doses that are right for you. Be sure you talk to your doctor about the right time to take the prescribed medications. If your doctor recommends Insulin for your diabetes management, this section offers some helpful tips and information. The aim of insulin therapy is to maintain the blood sugar within the range recommended by your doctor.

Know more about Insulin

Most people with type 2 diabetes eventually may need to take insulin to control their blood sugar levels. Remember controlling your blood sugar is far more important than the treatment you use, whether it's pills, insulin shots or both. Each person with diabetes is different. So their needs will also be different.

Choosing the site for an insulin shot

Knowing exactly where on your body you should give your shot(s) each day is very important.

Rotating sites

To keep your skin, fat, and muscle healthy, it's important to use a different location for each shot. Overusing a site can cause tissue changes that lower or changes insulin absorption. Talk to your doctor about preferred sites for your insulin injections.

Most insulin enters the blood:

Fastest from the abdomen(stomach) A little slower from the arms Even more slowly from the legs Most slowly from the buttocks Insulin enters the blood more quickly from some areas than others. So, your blood sugar may be higher or lower depending on what area is used. At times, you may want to use a certain area because of how quickly or slowly insulin is taken up from that site. For example, when you will be eating very soon after a shot, you could use a site on your stomach. The most common tool used to give insulin shots are syringes and pens. You may want to try both types to see what you like best. Ask your doctor or diabetes educator to show the differences.
