Reversal of Type 2 Diabetes in a Patient With Hashimoto's Thyroiditis Through Combined Pharmacologic and Lifestyle Intervention.

Type 2 diabetes mellitus (T2DM) is typically considered a progressive condition, but recent evidence suggests potential reversibility through structured lifestyle intervention. We report the case of a 32-year-old Egyptian female with Hashimoto's thyroiditis and newly diagnosed T2DM, confirmed by elevated fasting blood glucose and HbA1c levels. The patient was managed with once-daily metformin, continued levothyroxine, a 500-calorie daily energy deficit, and progressive resistance training three times per week. After 12 months, fasting glucose and HbA1c values decreased below the diagnostic thresholds for diabetes, allowing metformin to be discontinued. Follow-up at one, three, and six months post-intervention confirmed sustained biochemical remission. This case highlights the potential for reversing diabetes in select patients through a combined pharmacological and lifestyle approach.
