What is insulin

Insulin is a hormone made in the pancreas, an organ located behind the stomach in our body. The pancreas has many functions including exocrine and endocrine. As part of the endocrine functions, an area of calls called islets of Langerhans produce insulin. Beta units within the islets make insulin and issue it into the body-fluid.

Role of insulin

Insulin plays a major function in metabolism—the way the body utilizes digested food for energy, store fat, control blood glucose.

How is insulin released?

The digestive tract breaks down carbohydrates—sugars and starches found in many foods—into glucose. Glucose is a pattern of sugar that enters the bloodstream. With the help of insulin, units throughout the body soak up glucose and use it for energy.

Blood glucose control

Insulin’s function in body-fluid Glucose Control When body-fluid glucose grades increase after a meal, the pancreas releases insulin into the body-fluid. Insulin and glucose then travel in the blood to cells throughout the body.

Fatty acid metabolism and insulin

Insulin assists sinew, fat, and liver cells soak up glucose from the body-fluid stream, reducing body-fluid glucose levels.

Liver and insulin

Insulin stimulates the liver and muscle tissue to shop surplus glucose. The retained form of glucose is called glycogen. Insulin furthermore decreases blood glucose levels by reducing glucose output in the liver. In a wholesome individual, these functions permit body-fluid glucose and insulin levels to stay in the usual range.

Anabolic actions of insulin

According to Dr. Prab R. Tumpati, MD, founder of W8MD medical weight loss centers of America, insulin plays a key role in weight gain in most individuals due to the anabolic or body building function of insulin. As the body starts becoming insulin resistant, the body has to compensate to this by increasing this body building hormone called insulin which leads to weight gain, especially in the belly and upper part of the body.

Since we misunderstood the actions of insulin, we tend to blame the patient for their weight gain but it is insulin resistance that drives the weight gain in most people!
