Q. My friend has an iguana that gas been bloated for a day.
A. A bloated appearance can have several causes. Parasites, an impaction or, if your iguana is female, she could be gravid ("pregnant"). The best course of action is to see an experienced herp vet for an exam and proper diagnosis. Submit a stool sample to rule out parasites. An xray may diagnose an impaction (substrate, food, stool, etch.) or gravidity. Each condition has its own treatment. You can try soaking the iguana in a warm bath for 10-15 minutes while gently massaging the abdomen. If there is an impaction or constipation, this may help pass the stool. If the iguana is lethargic or not eating though, your friend should have it examined sooner rather than trying home treatment.
