Insulin is a hormone made by the pancreas that enables your body to use sugar (glucose) from carbohydrates in the food that you eat for energy or to save glucose for future use. Insulin assists keeps your blood glucose level from getting too expensive (hyperglycemia) or too low (hypoglycemia).
The cells in your body need sugar for energy. Nevertheless, sugar can not enter into the majority of your cells directly. After you eat food and your blood glucose level increases, cells in your pancreas (called beta cells) are indicated to release insulin into your bloodstream. Insulin then attaches to and signals cells to soak up sugar from the blood stream. Insulin is frequently described as a “crucial,” which opens the cell to enable sugar to go into the cell and be used for energy.
If you have more sugar in your body than it requires, insulin assists save the sugar in your liver and releases it when your blood sugar level is low or if you need more sugar, such as in between meals or during exercise. For that reason, insulin assists balance out blood sugar levels and keeps them in a normal variety. As blood sugar levels increase, the pancreas produces more insulin.
If your body does not produce sufficient insulin or your cells are resistant to the impacts of insulin, you might establish hyperglycemia (high blood sugar level), which can cause long-term complications if the blood sugar levels stay elevated for extended periods of time.
Individuals with type 1 diabetes can not make insulin due to the fact that the beta cells in their pancreas are harmed or ruined. For that reason, these individuals will need insulin injections to allow their body to procedure glucose and avoid complications from hyperglycemia.

People with type 2 diabetes do not respond well or are resistant to insulin. They might need insulin shots to help them much better procedure sugar and to avoid long-lasting complications from this disease. Individuals with type 2 diabetes may first be treated with oral medications, along with diet and exercise. Since type 2 diabetes is a progressive condition, the longer someone has it, the most likely they will require insulin to maintain blood glucose levels.
Different types of insulin are used to treat diabetes and include:
- Rapid-acting insulin: It starts working roughly 15 minutes after injection and peaks at around 1 hour however continues to work for two to 4 hours. This is typically taken prior to a meal and in addition to a long-acting insulin.
- Short-acting insulin: It starts working around 30 minutes after injection and peaks at around 2 to 3 hours however will continue to work for three to 6 hours. It is generally given prior to a meal and in addition to a long-acting insulin.
- Intermediate-acting insulin: It begins working around 2 to 4 hours after injection and peaks roughly 4 to 12 hours later and continues to work for 12-18 hours. It is usually taken two times a day and in addition to a fast- or short-acting insulin.
- Long-acting insulin: It starts working after numerous hours after injection and works for approximately 24 hours. If needed, it is often used in mix with quick- or short-acting insulin.
Insulin can be given by a syringe, injection pen, or an insulin pump that provides a continuous flow of insulin.
Your doctor will deal with you to figure out which type of insulin is best for you depending upon whether you have type 1 or type 2 diabetes, your blood sugar levels, and your lifestyle.
