Leopard Gecko Prolapse: What It Looks Like, Why It Happens & Emergency Care

A prolapse means tissue from inside the vent has pushed outside the body. In reptiles, that tissue may be cloaca, colon, oviduct, bladder, or in males, a hemipenis. The exact cause matters because some tissues can sometimes be replaced, while others may need a different approach. Your vet's first job is to identify what has prolapsed and why it happened.

In leopard geckos, prolapse often starts with straining. That can happen with constipation, gastrointestinal impaction, intestinal parasites, diarrhea, cloacal irritation, or dehydration. Husbandry problems can contribute too. Poor hydration, inappropriate substrate, and incorrect temperature gradients can all make normal stool passage harder. Merck also notes that metabolic disease, infection, masses, kidney disease, bladder stones, breeding trauma, and inflammation can be underlying causes of reptile vent prolapse.

Female leopard geckos may prolapse with reproductive problems such as retained eggs or difficult egg-laying. Male geckos can prolapse a hemipenis, which may look like red or purple tissue near the vent. In some cases, retained shed, trauma, or repeated licking and irritation around the vent can worsen swelling and make the tissue harder to replace.

Because prolapse is usually a symptom rather than a final diagnosis, successful treatment depends on correcting the trigger. If the underlying problem is missed, the tissue may prolapse again even after it is put back in.

See your vet immediately if you notice any tissue protruding from the vent. This is a same-day reptile emergency. Exposed tissue dries out fast, becomes swollen, and may lose blood supply. The darker, drier, or more contaminated it gets, the harder it is to save.

Do not monitor a true prolapse at home to see if it improves overnight. Even a small amount of pink tissue can worsen quickly. Go urgently if the tissue is dark red, purple, black, bleeding, dirty, foul-smelling, or if your gecko is weak, straining, not passing stool, or has a swollen belly.

The only things to do at home before the visit are supportive transport steps: keep the tissue moist with sterile saline or plain water, place your gecko on a clean paper towel in a secure carrier, keep the enclosure warm but not overheated, and minimize handling. Avoid loose substrate during transport.

If you are unsure whether you are seeing a prolapse or a bit of stool stuck at the vent, call your vet anyway and send a photo if the clinic allows it. A real prolapse should always be treated as urgent until proven otherwise.

Your vet will first identify the prolapsed tissue and assess whether it is still viable. That usually starts with a physical exam, review of husbandry, and questions about stooling, appetite, breeding history, egg production, shedding, and substrate exposure. In many reptile prolapse cases, the tissue is gently cleaned, lubricated, and reduced back into place if it is healthy enough.

If the tissue is swollen, your vet may use osmotic agents such as concentrated sugar solutions to help shrink edema before replacement. Sedation or anesthesia may be needed because reduction can be painful and delicate. If the prolapse keeps recurring, temporary sutures around the vent or a fixation procedure may be considered. Merck notes that some prolapsed reproductive tissue in male lizards, such as a nonfunctional hemipenis, may sometimes be surgically amputated if it cannot be saved.

Your vet may also recommend diagnostics to find the cause. Depending on the case, that can include fecal testing for parasites, radiographs to look for impaction or eggs, blood work, and evaluation of temperature, humidity, lighting, supplements, and diet. Treatment often includes fluids, pain control, anti-inflammatory care, parasite treatment when indicated, and husbandry correction.

Prognosis depends on how long the tissue has been out, what organ is involved, and whether the underlying cause can be corrected. Early treatment usually gives the best chance of preserving tissue and preventing recurrence.

Home care for a prolapse is supportive transport care, not definitive treatment. Keep the exposed tissue moist with sterile saline or plain water on a clean, lint-free dressing or damp paper towel. House your gecko temporarily on plain paper towels, not loose substrate, and keep the carrier warm and quiet on the way to your vet.

Do not try to cut tissue, pull on it, scrub it, or force it back inside. Do not apply ointments, essential oils, peroxide, alcohol, or human hemorrhoid products unless your vet specifically tells you to. These can damage delicate tissue or make it harder for your vet to assess the area.

After treatment, follow your vet's instructions closely. That may include a simple enclosure setup, careful hydration support, medication, stool monitoring, and strict temperature control. Leopard geckos need an appropriate thermal range to digest and pass stool normally, and husbandry correction is often part of preventing another prolapse.

Call your vet right away if the tissue comes back out, looks darker, starts bleeding, smells bad, or your gecko stops eating, strains, becomes lethargic, or does not pass stool. Recurrence is possible, especially if the underlying cause has not been fully corrected.
