Treatment for Insulin Resistance

Insulin resistance is one of the more responsive stages in this disease process — meaningful improvement is often possible through lifestyle changes alone.

What Actually Helps

• Physical activity — regular exercise helps muscles use glucose more effectively, improving insulin sensitivity relatively quickly
• Weight management — even a modest reduction in body weight, particularly around the abdomen, can meaningfully improve insulin sensitivity
• Dietary changes — reducing refined carbohydrates and added sugar, and favoring fiber-rich whole foods
• Adequate sleep — poor sleep is independently linked to worsened insulin sensitivity

When Medication Is Added

If lifestyle changes alone aren't enough, or if other risk factors are present, a doctor may prescribe a medication such as metformin. This is a decision made individually with a doctor, not something to self-start, and doesn't replace the lifestyle changes above.

A doctor typically tracks whether these changes are working through follow-up testing — such as repeat fasting insulin or HbA1c levels — rather than by symptoms alone, since insulin resistance itself usually doesn't cause noticeable symptoms.
