Insulin is a hormone that plays a vital role in the body by regulating the amount of sugar in a person's bloodstream and storing any excess glucose for energy. When a person eats, carbohydrates are broken down into sugar that can be found in the bloodstream. This becomes a person's energy source, and when insulin levels are high, this sugar in the bloodstream, also known as glucose, is stored in the liver for later use between meals.
Those suffering from diabetes will experience a spike in the level of sugar in the bloodstream due to a lack of insulin. If left alone, high blood sugar levels will leave a person feeling dehydrated, increase the frequency of urination and can cause fatigue. If high blood sugars are not treated for some time, they can lead to more severe complications like kidney damage and blindness. Insulin injections are used to keep blood glucose at the appropriate level to avoid such complications.
Insulin is created inside the body's pancreas and is released after every meal to assist the body with using or storing the blood glucose that is broken down from food. Those suffering from type 1 diabetes are lacking insulin because the pancreas has lost the ability to create it, and insulin injections must be used as a substitute. Those suffering from type 2 diabetes have problems responding to their body's insulin and would require diabetes pills or insulin shots to assist with the use of glucose.
Those who require insulin injections have several different types of insulin to choose from, all with varying strengths. The most common strength for insulin is U-100, although U-40 may still be used outside of the United States.
There are three things to remember when choosing from the different types of insulin:

Insulin injections are used mainly for those suffering from type 1 diabetes, although it may also be used for those suffering from type 2 diabetes. Insulin injections vary depending on what type of diabetes the person has. Insulin injections should be scheduled in accordance to meal times. Proper scheduling is important for finding the ideal time to allow insulin to enter the body to process the glucose from food that is eaten.
While a syringe is the most common form of insulin injection, there are insulin pens and pumps available as alternatives.
