What is the connection between insulin and blood sugar?

There is a direct connection between insulin and blood sugar. Insulin is a hormone that regulates blood sugar or glucose levels by helping cells use it for energy. In a healthy individual, the pancreas secretes insulin and more is released when blood sugar levels are high. When sugar is low in the bloodstream, less insulin is released. Dysfunctions of this system occur in people with diabetes, leading to potentially dangerous blood sugar levels if left unchecked.

The relationship between insulin and blood sugar is that insulin is responsible for keeping blood sugar at a healthy level. When a person eats, the digestive system converts food into glucose and releases it into the bloodstream. Sugar in the blood is taken up by cells throughout the body and used for energy. The hormone insulin is necessary for blood sugar to enter cells.

Large amounts of sugary or high-carbohydrate foods turn into blood sugar more easily than other foods. This can cause higher than normal blood sugar levels. When this occurs, the connection between insulin and blood sugar causes the pancreas to release additional insulin. The extra insulin allows cells to quickly absorb the extra sugar from the blood. This returns blood sugar to normal levels quickly, which is important because high blood sugar levels over a long period of time can be very unhealthy.

If a person has not eaten for a few hours, blood sugar levels may drop lower than normal. When this happens, due to the relationship between insulin and blood sugar, the pancreas will slow down its secretion of insulin. This helps the remaining blood sugar to be brought into the cells much more slowly, while the cells use the stored glucose for energy.

In some people, there is a malfunction of the relationship between insulin and blood sugar called diabetes. A person with diabetes lacks the proper insulin response to high blood sugar levels. This can happen due to the following reasons: the pancreas cannot produce and secrete the necessary insulin; the body does not respond correctly to insulin; or is not released in the correct amounts. Diabetes is a potentially dangerous disease that requires careful management and treatment that may include lifestyle changes and medications. There is no cure for diabetes, but people with diabetes can often live long and healthy lives if they are vigilant about controlling their blood sugar.
