Insulin Resistance: Causes, Symptoms and Treatment

Insulin resistance is a metabolic condition in which the body’s cells do not respond effectively to insulin. Insulin is a hormone produced by the pancreas that helps glucose enter cells to be used for energy. When the body becomes resistant to insulin, blood sugar levels start to rise, increasing the risk of prediabetes and type 2 diabetes.

Understanding insulin resistance is important because early lifestyle changes and medical treatment can help prevent the progression to diabetes. Individuals concerned about blood sugar levels can consult the best diabetologist in Chennai at Tambaram Medical Center for proper diagnosis and management.

What is Insulin Resistance?

Insulin resistance occurs when the body’s cells become less responsive to insulin. As a result, the pancreas produces more insulin to help move glucose from the bloodstream into the cells. Over time, this increased demand on the pancreas can lead to elevated blood sugar levels and eventually diabetes.

Insulin resistance is often associated with metabolic syndrome and may develop gradually without noticeable symptoms.

• Overweight or obesity
• Physical inactivity

• Poor dietary habits
