John J. Wysolmerski, MD

John Wysolmerski, MD, is an endocrinologist, a physician who specializes in hormone-related diseases and conditions.

He sees patients with a variety of endocrine disorders, as well as those with osteoporosis, which is the weakening of bones, resulting in an increased risk for fractures, and osteomalacia, the failure of bones to properly deposit minerals such as calcium and phosphate. He also treats patients with irregularities in parathyroid hormone production. Parathyroid hormone controls calcium, phosphorus, and vitamin D levels in the body.

Through the Yale Bone Center, Dr. Wysolmerski is working with Yale School of Medicine colleagues to develop a Fracture Liaison Service with the goal of reducing further fractures in patients who have suffered a previous fragility fracture by diagnosing osteoporosis or offering preventative therapy.

Dr. Wysolmerski’s research examines calcium and bone metabolism in women who are breastfeeding, as well as the mechanisms by which calcium is secreted into milk. He is also examining how changes in calcium and bone metabolism are altered in people diagnosed with breast cancer, especially those with bone metastases.

He is chief of the Section of Endocrinology at Yale School of Medicine and has published more than 100 scientific papers and has served on multiple editorial boards, including the Journal of Mineral and Bone Research, andEndocrinology.
