Insulin is a hormone produced by the pancreas that helps the body use glucose (sugar) for energy. It is essential for people with diabetes, a condition in which the body does not produce enough insulin or use it properly. Without insulin, glucose builds up in the bloodstream, leading to serious health problems.

Insulin helps the body use glucose by allowing it to enter cells, which can be used for energy. It also helps the body store glucose in glycogen, which can be used for energy. Insulin helps the body convert glucose into fat, which can be used for energy when glucose is not available. Insulin is available in several forms: short-acting, intermediate-acting, and long-acting.

Short-acting insulin is usually taken before meals to help control blood sugar levels after eating.

Intermediate-acting insulin is usually taken twice daily to help control blood sugar levels throughout the day.

Long-acting insulin is usually taken once a day to help control blood sugar levels over a longer period.

Insulin is usually taken by injection or through an insulin pump. Injections are usually done with a syringe or an insulin pen. Insulin pumps are small devices worn on the body and deliver insulin through a catheter.

Insulin is an important part of managing diabetes. It helps keep blood sugar levels in a healthy range and can help prevent serious health problems. It is important to talk to your doctor about the best type and dose of insulin for your needs.
