How has insulin changed and improved since Frederick Banting's discovery?

When insulin was first discovered there was only one kind on insulin available which was short lasting and people had to have many injections throughout the day to control their diabetes. Today there are many different kinds of insulin and ways to administer it. There are six different types of insulin today ranging from fast acting to long lasting insulin which requires only one injection throughout the day. When Banting first discovered insulin it had to be administered through a syringe which was much larger than the ones used today. Now days insulin can be administered through a pump, syringe, pen or injector. The most popular method of inulin injection is through a pen or insulin injector. All of the methods have the same end result- they deliver insulin, but the difference is that some are easier to use than others and some work better for different people's needs. Insulin pens look just like a regular pen you use for writing, but instead of the end of the pen having a ball point where ink comes out, it has a small needle that comes out and injects insulin. The pump is another new way of delivering insulin to the body. The pump works by inserting a small needle into fatty tissue in the stomach area and leaving it there. Throughout the day the pump will administer insulin as needed in small amounts required to control blood glucose levels. After about three days the needle needs to be removed and replaced. People still receive insulin through a syringe today, but they have adapted and changed since the discovery on insulin. They are now very small needles with a coating on them to make them as painless as possible. Insulin injection is no longer a painful and time consuming procedure as it was in Banting's time. It has evolved and become very individualized for the patients needs.
