How does insulin resistance relate to type 2 diabetes?

Insulin resistance is a key factor in the development of type 2 diabetes. Here's how they are connected:

• Insulin's Role: Insulin, a hormone produced by the pancreas, allows glucose from the bloodstream to enter cells for energy or storage, regulating blood sugar levels.

• Insulin Resistance: When cells become resistant to insulin's signals, glucose struggles to enter cells, leading to elevated blood sugar. We've discussed this in detail, highlighting how this resistance can stem from various factors, including excess body fat and chronic high blood sugar levels.

• Pancreatic Strain and Compensation: Initially, the pancreas tries to compensate for insulin resistance by producing more insulin. This can maintain blood sugar levels within a healthy range for a while.

• Progression to Type 2 Diabetes: However, prolonged overproduction of insulin can exhaust the pancreas, leading to a decline in insulin production. As the pancreas struggles to keep up, blood sugar levels rise further.

• Crossing the Threshold: When blood sugar levels consistently remain elevated due to the combined effects of insulin resistance and insufficient insulin production, a diagnosis of type 2 diabetes is made.

Essentially, insulin resistance sets the stage for type 2 diabetes by creating a chronic state of high blood sugar that the pancreas eventually can't manage.

Many sources emphasize that early detection and management of insulin resistance are crucial for preventing the progression to type 2 diabetes. Lifestyle changes like weight loss, regular exercise, and dietary modifications can improve insulin sensitivity and help prevent or delay the onset of type 2 diabetes.
