If you have Type 1 diabetes, you will definitely have to take insulin injections. If you have Type 2 diabetes, and it cannot be controlled with diet and exercise, you may also have to take insulin injections at some point.

Unfortunately, insulin cannot be taken orally, in pill or liquid form. This is because the digestive juices destroy the insulin, making it ineffective. However, these days, insulin can be injected with a needle and syringe, an insulin pen, or insulin pump.

Insulin is injected into the body just under the skin, in the fatty tissue. Today, there are approximately 20 different types of insulin, which are available in just four forms. Your doctor will determine which insulin product is right for you, based on your lifestyle, your blood sugar levels, and other factors including when the insulin will do the most good, how long it take the body to recognize and use the insulin, and how long the insulin will last in the body.

So, where does the insulin come from? For the most part, it is manufactured in labs. At one time, it came from cows and pigs, but insulin from cows is no longer acceptable in the United States and as of early 2006, insulin extracted from pigs is no longer manufactured.

Insulin used by diabetics is regulated by the Food and Drug Administration in the United States. When a pharmaceutical company manufactures a new insulin drug, the company is responsible for testing the insulin, and submitting detailed reports to the FDA. The FDA then analyzes the results, and determines whether or not the drug is safe for human consumption.

If you are diabetic, and you require insulin, your doctor will instruct you on purchasing insulin delivery devices, and show you how to inject yourself with the insulin. It is also a good idea to have a close family member learn how to inject the insulin, in the event that you cannot do it yourself.
