Insulin, we should understand the Importance of Insulin in diabetes because it helps control your blood sugar (glucose) level, so your body gets the energy required for daily activities. When the amount of sugar in the blood rises to a certain level, the pancreas will produce more insulin to push more glucose into the cells. This causes sugar levels in the blood to drop. Here, we are exploring the importance of insulin in diabetes, continue reading the blog to know more.

Importance of Insulin in Diabetes:



Insulin is a hormone that is produced by the pancreas which allows your body to use glucose (sugar) from carbohydrates in the food that you consume for energy or to store glucose for future use. It helps to keep your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia).



Insulin regulates the way how the body uses and stores fat and glucose. Most of the body’s cells rely on insulin to take glucose from the blood for energy.




Well, sugar does go into most of your cells directly. After you consume food your blood sugar level rises, cells in your pancreas called beta-cell are signaled to release insulin into your bloodstream. Insulin attaches to signals cells to absorb sugar from the bloodstream. it is usually described as a “key,” which unlocks the cell to allow sugar to enter the cell and can be used for energy.


People who are dealing with diabetes either their body’s cells are resistant to insulin or they don’t make insulin, which cause high sugar level circulated in your blood that is known as high blood sugar. If you have a blood glucose level of 126 milligrams per deciliter (mg/dL) or more in your blood after a whole night fasting then you are diabetic.



Insulin and Diabetes



It helps to control your blood glucose levels by indicating the muscle and liver as well as the fat cells to take in glucose from the blood. Insulin takes help from cells to take in glucose to be used for energy.

If the body has enough energy, insulin signals the liver to take the glucose up and store it as glycogen.

The liver can store up to almost 5% of its mass as glycogen.

Some cells in the body can take glucose from the blood cells without insulin, but most cells do require insulin to be present.

Insulin and Type 1 Diabetes



In type 1 diabetes, the body does not produce sufficient insulin to regulate blood glucose levels.

Absence of insulin, many of the body’s cells that cannot take glucose from the blood and so the body uses other sources of energy.

Ketones which are made by the liver as another alternative source of energy, however, high levels of the ketones can lead to a dangerous condition which is called ketoacidosis.

People with type 1 diabetes will need to inject insulin to fulfill the requirement of the body lack of insulin.



Insulin and Type 2 Diabetes



Type 2 diabetes is characterized by the body when the body is not responding successfully to insulin. This is called insulin resistance. Resulting, the body is not completely capable to take up glucose from the blood. In the earlier stages of type 2 diabetes, the body responds by producing more insulin which would normally need by the body.



If type 2 diabetes progress over a number of years, the excess demands on the pancreas to make insulin which can lead to a loss of insulin-producing cells also called pancreatic beta cells as they wear out.



Depending on the level of insulin resistance, people who are having type 2 diabetes can also need to take insulin injections to manage the blood sugar levels.





Insulin plays an important role in our body,  it controls the glucose or sugar level in the blood. If you are diabetic then the insulin level in the body reduces which increases the glucose or sugar level in the body. To manage it you should consult a diabetologist, he/she will help you to regulate the levels.
