This Q&A features Maria Altieri, MD, MS, FACS, section chief of GI surgery and director of bariatric surgery at Penn Medicine’s Pennsylvania Hospital.

In addition to performing minimally invasive and robotic bariatric procedures, Dr. Altieri is responsible for the quality of care delivered to patients seeking medical help with their weight loss goals.

Historically, weight has been a difficult topic for patients and providers. However, the emergence of GLP‑1 medications has motivated patients to be proactive about discussions with providers about obesity and obesity‑related comorbidities. This has introduced more opportunities to communicate the potential benefits of different approaches (medical, endoscopic, or surgical weight loss).
