Crested Gecko Cholangitis: Bile Duct and Liver Inflammation in Crested Geckos

Crested gecko cholangitis means inflammation of the bile ducts, the small channels that move bile from the liver. In many animals, inflammation in this area can also involve nearby liver tissue, sometimes called cholangiohepatitis. Bile helps with digestion, but when bile ducts become inflamed or blocked, the surrounding tissue can become irritated and damaged.

In crested geckos, this condition is considered uncommon and usually needs an exotic animal workup because reptiles often hide illness until they are quite sick. Signs are often vague at first. A gecko may eat less, lose weight, seem weak, spend more time hiding, or stop climbing normally.

Because reptiles depend heavily on proper temperature, hydration, and nutrition, liver and bile duct disease may develop alongside husbandry problems or other illness rather than as a completely isolated issue. That is why your vet will usually look at the whole picture, including enclosure temperatures, humidity, diet, supplements, stool quality, and any recent stressors.

See your vet immediately if your crested gecko is severely weak, not eating, dehydrated, losing weight quickly, or showing dark coloration, swelling, or trouble moving. Reptiles can decline fast once liver function is affected.

Cholangitis usually develops when inflammation reaches the bile ducts from another problem. In reptiles, that may include bacterial infection, spread of infection through the bloodstream, or extension from the gastrointestinal tract. In some cases, parasites, systemic fungal disease, or severe inflammatory disease may also affect the liver and nearby biliary tissue.

Husbandry matters too. Incorrect temperatures can slow digestion and immune function. Poor sanitation can increase exposure to infectious organisms. Chronic dehydration may reduce normal bile flow and worsen overall organ stress. Nutritional imbalance, obesity, prolonged anorexia, and inappropriate supplementation may also contribute to liver disease that makes bile duct inflammation more likely.

Medication reactions and toxin exposure are less common but still possible. Any recent change in supplements, cleaning products, enclosure materials, feeder insect quality, or medications is worth discussing with your vet.

Sometimes no single cause is found right away. Your vet may treat the gecko supportively while also working to identify whether infection, husbandry, nutrition, or another underlying disease is driving the inflammation.

Diagnosis usually starts with a detailed history and physical exam. Your vet will ask about enclosure temperatures, humidity, UVB if used, diet, supplements, recent egg laying, stool changes, weight trends, and any new stressors. In reptiles, these details are often as important as the exam itself.

Initial testing may include bloodwork to look at liver-related values, hydration status, protein levels, and signs of infection or inflammation. Fecal testing may help rule out parasites or gastrointestinal disease. Radiographs can look for organ enlargement, retained eggs, masses, mineralization, or other causes of illness.

If your vet is concerned about liver or bile duct disease, ultrasound may help evaluate the liver, gallbladder, and surrounding tissues. In some cases, sedation is needed to reduce stress and improve image quality. A definitive diagnosis may require cytology, culture, or biopsy, especially if your vet needs to confirm infection, inflammation type, or the extent of liver involvement.

Because cholangitis can look like many other reptile illnesses, diagnosis is often a stepwise process. Your vet may begin with the least invasive tests and then adjust the plan based on your gecko's stability and your goals for care.

Prevention focuses on lowering the everyday stresses that can set reptiles up for internal disease. Keep enclosure temperatures and humidity in the correct range for crested geckos, provide clean water, and maintain good sanitation. Remove waste promptly, disinfect appropriately, and avoid overcrowding or mixing reptiles without quarantine.

Feed a balanced crested gecko diet from a reputable source, with insects offered appropriately and gut-loaded when used. Avoid overfeeding high-fat items, and review supplements with your vet so calcium and vitamin use stay appropriate for your gecko's age and life stage.

Routine wellness visits matter, especially because reptiles often hide illness. Your vet may recommend periodic weight checks, fecal testing, and baseline bloodwork or radiographs for some patients. Early changes in appetite, stool, or body condition are easier to address before liver disease becomes advanced.

If your gecko stops eating, loses weight, or seems less active, do not wait for dramatic symptoms. Prompt veterinary care and a careful husbandry review are the best ways to prevent a mild problem from becoming a serious liver or bile duct condition.
