Dr. Wexler is quick to figure out when things have gone awry. For example, she realized that I needed less Metoprolol, and she noticed from my thyroid blood tests that I have hypothyroidism and acted promptly. She also advised me on how to lower my blood sugar, which has become elevated despite the fact that I have lost weight and exercise most days of the week.
