Abstract

In avian practice, loss of body condition is a common presentation. In general, birds with weight loss must always be treated as emergencies as such a condition may quickly lead to death. This chapter equips the reader with the necessary tools to diagnose the cause of and subsequently treat weight loss. Case examples: African Grey Parrot with chronic weight loss and acute seizures; Blue-fronted Amazon with liver fibrosis; Golden Parakeet with avian bornavirus.
