ABSTRACT
Vomiting can be a symptom of many conditions, some relatively harmless and others life threatening. Vomiting can quickly lead to severe dehydration and/or starvation. The cause of vomiting can be a disorder inside or outside the gastrointestinal tract. Vomiting can be the result of disorders outside the gastrointestinal tract and can cause complications including dehydration and changes in electrolyte concentrations. Ideally, blood should be collected for hematology and biochemistry. Once vomiting/regurgitation has stopped by suppressing nausea, nutrition should be offered. Because sick birds are frequently anorectic (for reasons other than nausea), tube feeding is indicated in many cases after the vomiting/regurgitation has stopped. Flagellates can be treated with oral antiprotozoal drugs from the nitroimidazoles class (e.g., metronidazole, ronidazole). Worm infections can be treated with anthelmintics (e.g., fenbendazole, flubendazole, ivermectin, praziquantel).
