Clemens W.H. Bergwitz, MD, is an endocrinologist at Yale Medicine who sees patients with primary hyperparathyroidism, general endocrine disorders, hyperthyroidism, thyroid nodules, adrenal disorder, hypophosphatemic disorders and hypogonadism.

Dr. Bergwitz’s characterizes the endocrine system as the human body’s own data messaging system. “It sends information to regulate some of our body’s most critical functions,” he says. In addition to treating patients, Dr. Bergwitz conducts research on many of these conditions, and his lab has worked on projects that test various therapies for hereditary endocrine disorders. “I am really a physician-scientist. My patients inspire my research, which eventually leads back to the bedside,” he says.

Dr. Bergwitz believes that patients should be the expert of their own illness. He strives to explain conditions and treatments in plain language so that patients not only understand their disorder, but also the biological mechanisms behind it. “I’m interested in providing my patients with the information they need to not only understand their condition, but to empower them to take good care of themselves,” he says.
