What is Internal Medicine?

Dr. Lechner is a Diplomate of the American College of Veterinary Internal Medicine. In human medicine, an internal medicine doctor is usually a primary care provider. However, in veterinary medicine, internal medicine is a specialty. As a board-certified internal medicine specialist, Dr. Lechner sees a wide variety of cases involving a multitude of organ systems and diseases including, but not limited to, renal (kidney) disease, diabetes, endocrine disease, blood disorders, cancer, lung disease, immune-mediated disorders, and gastrointestinal disease. She utilizes a number of techniques to evaluate her patients, including specialized blood tests, ultrasound, endoscopy (upper GI endoscopy, colonoscopy, bronchoscopy, rhinoscopy, cystoscopy), bone marrow biopsy, airway sampling, and limited echocardiography. Dr. Lechner and her team strive to provide exemplary medical care while giving owners answers to questions about their sick pets. Their goal is to optimize quality of life and to enhance the relationships between owners and their pets.
