Insulin resistance is a condition where the body's cells become less responsive to the hormone Insulin, which is crucial for regulating blood sugar levels. This can lead to higher blood sugar levels and may eventually result in Type 2 Diabetes if not managed properly. Several factors contribute to insulin resistance, including obesity, physical inactivity, and genetic predisposition. Lifestyle changes such as a balanced diet and regular exercise can help improve insulin sensitivity and reduce the risk of developing related health issues.
