Clinical Signs, Diagnosis and Pitfalls

This webinar is available from April 15 2026.

Hypoadrenocorticism, or Addison’s disease, occurs relatively frequently in dogs and is very rare in cats. As a result of insufficient production of glucocorticoids and mineralocorticoids by the adrenal cortex, animals with Addison’s disease may present with life-threatening clinical signs such as severe hypovolemia, hypotension, marked electrolyte abnormalities, metabolic acidosis, and hypoglycemia. However, when there is only a deficiency in glucocorticoid production, the clinical signs can be much more vague and often chronic in nature. In these animals, the typical electrolyte abnormalities are absent, and a strong clinical suspicion is essential in order to reach the correct diagnosis.

This course begins with an extensive discussion of adrenal physiology and the clinical signs with which affected animals may present. It then covers the different diagnostic tests that can be used, as well as treatment strategies, distinguishing between the emergency treatment required during an acute Addisonian crisis and the long-term management of this condition.

The course consists of several chapters (modules). Each chapter includes a short video of a pre-recorded presentation. In addition, you will receive recommended reading material and handouts of the full lecture, and you will have the opportunity to work through one clinical case independently. Questions for the instructors can be posted on the online forum.

Yi completed her veterinary studies and internship in 2013 at the University of Ghent and obtained her specialization in Internal Medicine in 2019 in Giessen (Germany). She then worked as a clinical supervisor in the Department of Internal Medicine at the University of Giessen.

Yi built an extensive academic career in various university hospitals. She had the opportunity to work with renowned professors in her field at the universities of Ghent, Utrecht and Bern, each time in the role of specialist in Internal Medicine. In 2022, she worked for a year at the largest private veterinary clinic in Hong Kong, where she became acquainted with the ins and outs of practice outside the university.

Exploring new environments, learning from and working with different experts and experiencing new cultures was always central and essential to her personal growth. That is why she decided to explore the world, together with her partner, their adorable cat Nidalee and adventurous dog Harper, bit by bit, country by country. Yi has been working online since 2023, as a consultant for primary care veterinarians on challenging cases and as a lecturer for various courses in her field. She also remains practically active through locums in clinics around the world. She supplements this with volunteer work at various local animal shelters.


Yi schloss 2013 ihr Studium der Tiermedizin sowie ihr Internship an der Universität Gent ab und erlangte 2019 ihre Spezialisierung in der Inneren Medizin in Gießen (Deutschland). Anschließend arbeitete sie als klinische Supervisorin in der Abteilung für Innere Medizin an der Universität Gießen.

Yi baute eine umfangreiche akademische Laufbahn an verschiedenen Universitätskliniken auf. Sie hatte die Möglichkeit, mit renommierten Professorinnen und Professoren ihres Fachgebiets an den Universitäten Gent, Utrecht und Bern zusammenzuarbeiten, jeweils in der Funktion als Spezialistin für Innere Medizin. Im Jahr 2022 arbeitete sie ein Jahr lang in der größten privaten Tierklinik in Hongkong, wo sie wertvolle Einblicke in die Arbeit außerhalb des universitären Umfelds gewann.

Das Erkunden neuer Umgebungen, das Lernen von und Arbeiten mit unterschiedlichen Expertinnen und Experten sowie das Erleben neuer Kulturen waren stets zentrale Elemente ihrer persönlichen Entwicklung. Aus diesem Grund entschied sie sich, gemeinsam mit ihrem Partner, ihrer Katze Nidalee und ihrem abenteuerlustigen Hund Harper die Welt Schritt für Schritt, Land für Land, zu bereisen. Seit 2023 arbeitet Yi online als Beraterin für Erstlinien-Tierärztinnen und -Tierärzte bei komplexen Fällen sowie als Referentin für verschiedene Fortbildungen in ihrem Fachgebiet. Zudem bleibt sie durch Vertretungstätigkeiten in Tierkliniken weltweit praktisch tätig und ergänzt dies durch ehrenamtliche Arbeit in lokalen Tierschutzorganisationen.
