Executive summary

Dr. Ania M. Jastreboff is an adult and pediatric endocrinologist with clinical expertise in obesity medicine and weight management and holds multiple board certifications; Yale’s faculty profile states she trained in both adult and pediatric endocrinology and “attain[ed] board certification in five specialties (endocrinology, pediatric endocrinology, obesity medicine, internal medicine, and pediatrics)” [1]. Public physician directories corroborate her specialization in endocrinology and obesity medicine though they vary in the exact list of certifications presented [2] [3].

1. Yale’s authoritative listing of training and certifications

Yale School of Medicine’s profile for Ania M. Jastreboff, MD, PhD explicitly describes dual training in adult and pediatric endocrinology and records five board certifications—endocrinology, pediatric endocrinology, obesity medicine, internal medicine, and pediatrics—while also noting her leadership roles in obesity research and clinical practice [1]. That institutional page is the clearest single-source statement tying her clinical specialties to the specific certifications claimed [1].

2. How other professional directories represent her specialties

Independent clinician directories repeat that Dr. Jastreboff practices diabetes, metabolism and obesity medicine and is board certified in adult endocrinology and pediatric endocrinology, with some listings explicitly adding obesity medicine as a certification [2] [3]. Those profiles align with Yale’s depiction of her clinical focus—diabetes, metabolic disease, obesity and both adult and pediatric endocrine care—though they sometimes state a narrower subset of certifications rather than the full five enumerated on Yale’s page [2] [3].

3. Clinical roles that reflect those specialties

Yale’s profile documents roles consistent with her stated specialties: director of the Yale Obesity Research Center (Y‑Weight), co‑director of the Yale Center for Weight Management, and involvement in guideline development and governance at obesity societies and boards—positions that match a clinician‑scientist working at the intersection of endocrinology and obesity medicine [1]. These leadership and clinical titles reinforce the practical application of her board‑level qualifications in obesity and endocrine care [1].

4. Discrepancies, verification limits, and why they matter

Public directories and commercial sites sometimes list overlapping or abbreviated certification sets and include disclaimers that they do not independently verify board credentials [4] [5] [6] [3], creating potential apparent discrepancies with academic profiles; Yale’s institutional statement remains the most direct source for her training and the five‑specialty certification claim [1]. Because third‑party aggregators may omit or summarize certifications and explicitly warn about verification limits, the institutional profile should be treated as the primary reference while recognizing that state medical boards or ABMS records would be needed for independent confirmation beyond Yale’s reporting [4] [5] [6] [3].

5. Name collisions and misinformation that can muddy the record

Searches for “Dr. Ania” pull up many different physicians (radiologists, neurologists, internists, psychiatrists, anesthesiologists) named Ania across multiple platforms, which increases the risk of conflating credentials among similarly named clinicians [4] [7] [8] [9] [10]. Yale’s profile also flagged recent misinformation that linked unrelated “pink salt trick” weight‑loss claims to Dr. Jastreboff—an explicit correction that the trick is unsupported and not connected to her or Yale—underscoring how viral content can create false associations [1].

6. Bottom line

The best available, institutionally sourced reporting identifies Dr. Ania M. Jastreboff as trained in adult and pediatric endocrinology with board certifications in endocrinology, pediatric endocrinology, obesity medicine, internal medicine, and pediatrics, and as a clinical leader in obesity and weight‑management programs at Yale [1]; independent directories corroborate her endocrinology and obesity medicine focus though they may list a narrower certification set and carry verification disclaimers [2] [3] [4].
