How can we get my wife's high blood sugar under control when her three-month average blood sugar (HbA1c) is 10.2%, her fasting blood sugar is 170, and her post-meal blood sugar is 135, even though she has been taking Januvia 100mg (once daily), Glimmer (once daily), and Glycomet 500 (three times daily) for the past four years?
An HbA1c of 10.2% indicates that her current regimen of Januvia (sitagliptin), Glimmer (glimepiride), and Glycomet (metformin) is no longer controlling her blood sugar effectively. Over time, the body's response to diabetes medications can change. I highly recommend scheduling a consultation with her doctor or an endocrinologist soon. They may consider adjusting her metformin dose, exploring newer medication classes, or discussing insulin therapy to safely bring her levels back into a healthy range.
