Leopard gecko: a 214-animal study links its health problems to husbandry setup
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
A leopard gecko that isn't doing well often shares something with other similar cases: a detail of its setup. A 2026 UK study confirms this using real clinical records rather than breeder intuition (, doi 10.1002/vetr.70971). Find our other guidance in the reptile bedding and habitat section.

Five years of records across three clinics
Henley and colleagues retrospectively reviewed the records of 214 leopard geckos presented between 2019 and 2023 at three UK veterinary practices. Reduced appetite, weight loss and lethargy were among the most commonly reported reasons for a visit — non-specific signs that make the clinical exam all the more important.
Shedding problems top a precise ranking
A diagnosis was reached for 184 of the 214 animals, around 86% of the sample. Skin came out on top among affected systems (37.90%), ahead of the digestive tract (36.00%) and the eyes (22.00%). Broken down by specific diagnosis, dysecdysis — an incomplete or poorly completed shed — dominated by far, at 29.96% of cases, followed by an internal parasite burden (10.75%) and presumptive hypovitaminosis A (9.88%). Importantly, the authors link several of these disorders to identifiable husbandry factors, not just causes internal to the animal.
What the study doesn't show
The sample remains modest, and clinical records don't always spell out the exact humidity level, substrate type or precise terrarium temperature: the authors themselves note that this incomplete data limits how finely a specific husbandry factor can be tied to a specific disorder. The study therefore can't isolate with certainty which exact oversight causes which problem, only confirm that a statistical link exists overall.
What this means in practice
With dysecdysis topping the diagnosis list, the number-one thing to watch is humidity available in a shedding hide, already covered in detail in our guide on the humid hide for leopard gecko shedding; see also our article on incomplete shedding at the toes and tail to catch the signs before they worsen.

Frequently asked questions
Is an occasional bad shed serious in a leopard gecko?
A one-off incident is common and rarely serious, but dysecdysis that repeats at every shed almost always signals a humidity or hide problem worth fixing rather than plain bad luck.
Does the study prove poor husbandry always causes these disorders?
No, it establishes a statistical association between certain husbandry factors and certain disorders, without being able to guarantee a cause-and-effect link for every individual case: other factors, such as genetics or age, play a role too.
