Extrapolating knowledge from DM in mammals is challenging because of marked differences in avian physiology and metabolism. A literature review from December 1991 to January 2022 identified 14 publications covering 16 diabetic birds, 63% (10\/16) of which belonged to the order Psittaciformes with Ara as the predominant genus. No sex predilection was noted, but males generally presented at a younger age. Commonly reported clinical signs included polyuria 94% (15\/16), polydipsia 88% (14\/16), weight loss 75% (12\/16), lethargy 63% (10\/16), and polyphagia 38% (6\/16). Diagnosis of DM was based on the presence of clinical signs and persistent hyperglycemia 100% (16\/16), often with glucosuria 93% (13\/14), response to insulin therapy 80% (8\/10), and pancreatic pathology 90% (9\/10). Specific treatment for DM was initiated in 14 patients, but blood glucose regulation for 6 months or longer was only achieved in 6 birds. Five of the regulated birds were managed with injectable long-acting insulin and 1 with oral glipizide combined with dietary modifications. However, glipizide yielded poor results in other cases, likely attributable to a lack of functional beta cells. Three diabetic birds progressed to remission. Treatment proved unsuccessful for 7 patients with a mean survival time of 36 days from diagnosis. One patient was lost to follow-up, and 2 were euthanized immediately following diagnosis. Histological examination of the pancreas frequently (90%, 9\/10) revealed abnormalities including atrophy, fibrosis, and vacuolization of the endocrine islets with or without lymphoplasmacytic pancreatitis. Comorbidities, including hemosiderosis and infection, were common. This review suggests that birds diagnosed with DM are primarily affected by a type I diabetes as observed in dogs and humans. In contrast to mammalian species, avian DM is often associated with underlying disease and a complete clinical workup is essential to diagnose and address secondary disease conditions prior to initiating long-term insulin therapy.<\/jats:p>","DOI":"10.1647\/avianms-d-22-00057","type":"journal-article","created":{"date-parts":[[2024,5,7]],"date-time":"2024-05-07T05:00:53Z","timestamp":1715058053000},"page":"21-33","source":"Crossref","is-referenced-by-count":8,"title":["Avian Diabetes Mellitus: A Review"],"prefix":"10.1647","volume":"38","author":[{"given":"Yannick","family":"Van de Weyer","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stamatios Alan","family":"Tahas","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1222","reference":[{"key":"40","unstructured":"M.
