Foreign body ingestion in iguanas is a common but serious medical condition that can lead to gastrointestinal (GI) obstruction, perforation, and death if left untreated. While some materials pass naturally, many require veterinary intervention.
Common Symptoms
Signs are often nonspecific and can develop over several weeks.
Appetite Loss (Anorexia): Sudden or progressive refusal to eat.
Lethargy: Noticeable decrease in activity or alertness.
Abdominal Distension: Visible swelling or "bloat" in the coelom (abdominal cavity).
Absence of Defecation: A halt in bowel movements (obstipation).
Vomiting: While rare in lizards, it can occur with severe obstructions.
Prolapse: Straining can cause cloacal or pe**le prolapse
Causes & Risk Factors
Iguanas may accidentally or intentionally ingest non-food items due to their feeding habits or environmental conditions.
Substrates: Pebbles, gravel, sand, or wood chips from their enclosure.
Textiles: Items like gauze bandages, cotton, or even socks.
Other Objects: Metallic items such as coins or neodymium magnets and metal pieces
Environmental Triggers: Nutritional deficiencies or lack of environmental enrichment can lead to "pica" (eating non-food items).
Diagnosis and Treatment
Diagnostic Tools: Radiography (X-rays) to find radiopaque objects (stones, metal) and ultrasound or CT scans for radiolucent ones (cloth, plastic).
Medical Management: In minor cases, supportive care like paraffin oil, fluid therapy, and motility stimulants may help pass the object.
Surgical Intervention: Large or sharp objects often require gastrotomy (stomach surgery) or enterotomy/typhlotomy (intestinal surgery) to remove the obstruction.
