Insulin resistance is primarily caused by a combination of lifestyle, genetic, and environmental factors. Key contributors include:
- Obesity: Excess body fat, particularly visceral fat around the abdomen, disrupts insulin signaling.
- Physical Inactivity: Lack of exercise reduces muscle glucose uptake, worsening insulin sensitivity.
- Poor Diet: Diets high in refined carbohydrates, sugars, and processed foods increase blood sugar and fat storage, straining insulin function.
- Genetics: Family history or certain genetic predispositions can increase susceptibility.
- Other Factors: Hormonal disorders (e.g., PCOS), chronic stress, sleep deprivation, and inflammation also play roles.
Addressing these through weight management, exercise, and a balanced diet can help reverse or manage insulin resistance. Want more details on any specific cause?
