Insulin Resistance: Causes, Signs and Fixes
When cells ignore insulin, the body compensates until it cannot.
What happens
Muscle, liver and fat cells respond poorly to insulin, so the pancreas makes more. Over years blood sugar rises and type 2 diabetes can develop.
Signs
Belly fat, dark skin patches called acanthosis nigricans, high triglycerides, low HDL and fatigue are common. Many people have no symptoms.
Improving sensitivity
Strength and aerobic exercise, sleep, weight loss and fibre-rich food improve insulin sensitivity quickly, often within weeks.
