Insulin Side Effects

What is Insulin?

Insulin is a natural hormone produced in the body. Man made or synthesized insulin is normally used as a medication in combination with an exercise program and diet plan to reduce high blood sugar levels in those with diabetes. Man made insulin replaces the functions of human insulin, which is to regulate blood sugar levels. There are many forms of insulin drugs that are used to treat people with diabetes. Diabetes refers to a chronic condition where a person does not produce enough insulin, or their body is not able to use it properly. Insulin is a naturally-occurring hormone which works by processing and absorbing glucose from the bloodstream body’s cells to use as energy. When you eat carbohydrate-rich foods, glucose is absorbed into the bloodstream. Glucose is a form of sugar, which is one of the greatest sources of fuel for the cells in the body. Without insulin, glucose cannot get into the body’s cells, thus they stay in the bloodstream. Too much blood sugar can lead to serious health complications, such as nerve problems, kidney damage, or blindness. People with diabetes are prescribed to use insulin medications to help them control their blood sugar levels. This medication works by helping glucose get into the muscle cells for energy. It also works by reducing the amount of glucose that is produced by the liver. This helps to reduce high blood sugar levels in people with diabetes. Insulin medication can be used alone or in combination with oral diabetes drugs like metformin.
