Mr Kelkar

माझाच या result वर विश्वास बसत नाहीय्ये की HbA1c प्रथम 12.7 ईतके भयानक होते .व आत्ता 5.4 ईतके नॉनडायबेटीक रिडींग येऊ शकते.
हा एक चमत्कारच वाटतोय. सर्जरी पूर्वी मला एवढा चांगला रिझल्ट मिळेल असं अजिबात वाटलं नव्हतं. वजन कमी झाल्याच्या आनंदापलीकडील हा आनंद मला डॉसने दिला. आभारासाठी माझ्याकडे शब्द नाहीत..
