Leopard Gecko Health Problems: Symptoms and When to Worry
The most common Leopard Gecko health problems are metabolic bone disease, impaction, and stuck shed. Leopard Geckos typically live 15–20 years. This page is organized by symptom, so you can jump straight to digestive, joint, skin, and eye problems, see what each one looks like in a Leopard Gecko, and know whether it is a vet visit this week, a vet visit today, or an emergency right now.
Quick answer: when to worry about your Leopard Gecko
Go to an emergency vet now if you see any of these:
- Stomach and digestive: A reptile straining without passing anything, a hard swollen belly, or regurgitating meals more than once is an emergency (impaction or a blockage). Prolapse of any tissue from the vent needs a vet within hours.
- Joint, back, and mobility: A reptile with a limb it cannot move, a soft or bent jaw, or tremors is an emergency, usually metabolic bone disease or a fracture. Both need a vet, not a heat lamp.
- Skin and coat: Retained shed cutting off circulation to toes or the tail tip, a spreading dark or wet patch of scales (scale rot), or a burn from a heat source needs a vet within a day.
- Eye: An eye that is swollen shut, has retained shed stuck over it, or is sunken with the animal off its food needs a vet. Sunken eyes usually mean dehydration.
- Any pet: collapse, seizures lasting more than five minutes, uncontrolled bleeding, or an inability to stand.
Book a vet visit this week if you see any of these:
- Stomach and digestive: Vomiting or diarrhea lasting more than 24 hours, refusing food for more than a day, or unexplained weight loss.
- Joint, back, and mobility: Limping for more than a day or two, stiffness after rest, reluctance to jump or climb stairs, or a change in gait.
- Skin and coat: Persistent itching, hair or quill loss, hot spots, sores, or a smell that does not go away after a bath.
- Eye: Book a vet visit for any cloudiness, redness, squinting, discharge, or a change in how they navigate a room, especially at dusk.
Keep watching if: the change is mild, your Leopard Gecko is still eating, drinking, and moving normally, and it resolves within a day or two. Write down what you saw and when; a dated list is the most useful thing you can bring to a vet.
Stomach and digestive problems in Leopard Geckos
Impaction
A blockage of the gut from swallowed substrate (sand is the usual culprit), oversized insects, or dehydration.
What it looks like in a Leopard Gecko:
- No droppings for more than a week
- Swollen belly, sometimes a dark bluish spot visible through the skin
- Straining, loss of appetite
- Dragging the back legs
Outlook: this is one of the conditions that can shorten a Leopard Gecko's life. Managed early it is often years, not months, but it belongs on the list of things that eventually lead to end-of-life decisions.
Cryptosporidiosis ("stick tail")
A parasitic gut infection that causes severe wasting. Highly contagious between geckos and very hard to clear. Often fatal.
What it looks like in a Leopard Gecko:
- Rapid loss of tail fat: a thin, stick-like tail
- Regurgitating food
- Runny or unusually smelly droppings
- Weight loss despite eating
Outlook: this is one of the conditions that can shorten a Leopard Gecko's life. Managed early it is often years, not months, but it belongs on the list of things that eventually lead to end-of-life decisions.
When to see a vet: Vomiting or diarrhea lasting more than 24 hours, refusing food for more than a day, or unexplained weight loss.
When it is an emergency: A reptile straining without passing anything, a hard swollen belly, or regurgitating meals more than once is an emergency (impaction or a blockage). Prolapse of any tissue from the vent needs a vet within hours.
Joint, back, and mobility problems in Leopard Geckos
Metabolic bone disease (MBD)
A calcium deficiency that softens the bones. Caused by no calcium or vitamin D3 supplementation, or no UVB. Reversible if caught early; deforming and fatal if not.
What it looks like in a Leopard Gecko:
- Soft, rubbery lower jaw
- Bowed or kinked legs, spine, or tail
- Tremors or twitching toes
- Difficulty lifting the body off the ground, dragging
Outlook: this is one of the conditions that can shorten a Leopard Gecko's life. Managed early it is often years, not months, but it belongs on the list of things that eventually lead to end-of-life decisions.
When to see a vet: Limping for more than a day or two, stiffness after rest, reluctance to jump or climb stairs, or a change in gait.
When it is an emergency: A reptile with a limb it cannot move, a soft or bent jaw, or tremors is an emergency, usually metabolic bone disease or a fracture. Both need a vet, not a heat lamp.
Skin and coat problems in Leopard Geckos
Stuck shed (dysecdysis)
Retained shed on the toes and around the eyes cuts off circulation or irritates the eye. Caused by low humidity or no humid hide.
What it looks like in a Leopard Gecko:
- Bands of old skin around the toes, toe tips turning dark
- Skin stuck around the eyelids, eye held closed
- Patchy, incomplete sheds
When to see a vet: Persistent itching, hair or quill loss, hot spots, sores, or a smell that does not go away after a bath.
When it is an emergency: Retained shed cutting off circulation to toes or the tail tip, a spreading dark or wet patch of scales (scale rot), or a burn from a heat source needs a vet within a day.
Eye problems in Leopard Geckos
Eye problems
Retained eyelid shed, corneal scratches from substrate, and vitamin A deficiency all show up as a swollen or closed eye.
What it looks like in a Leopard Gecko:
- Keeping one eye closed
- Swelling or discharge around the eye
- Cloudy eye or visible debris under the lid
When to see a vet: Book a vet visit for any cloudiness, redness, squinting, discharge, or a change in how they navigate a room, especially at dusk.
When it is an emergency: An eye that is swollen shut, has retained shed stuck over it, or is sunken with the animal off its food needs a vet. Sunken eyes usually mean dehydration.
Dental and mouth problems in Leopard Geckos
Mouth rot (infectious stomatitis)
A bacterial infection of the gums, usually secondary to stress, injury, or poor husbandry.
What it looks like in a Leopard Gecko:
- Swollen, red gums
- Yellow or white cheesy material in the mouth
- Refusing food
- Drooling
When to see a vet: Bad breath, drooling, dropping food, chewing on one side, or red gums.
When it is an emergency: Swelling along the jaw, pus in the mouth, or refusing food is mouth rot and needs a vet.
Reproductive problems in Leopard Geckos
Egg binding (females)
A female unable to pass her eggs, usually from low calcium or no suitable laying site.
What it looks like in a Leopard Gecko:
- Visible eggs through the belly that do not pass
- Restless digging then lethargy
- Loss of appetite
- Straining
Outlook: this is one of the conditions that can shorten a Leopard Gecko's life. Managed early it is often years, not months, but it belongs on the list of things that eventually lead to end-of-life decisions.
When to see a vet: Any discharge, swelling of the abdomen, repeated clutches in a bird, or a lump on the mammary chain.
When it is an emergency: A bird or reptile straining to pass an egg, or an unspayed female with a swollen belly, vomiting, and lethargy (pyometra), is an emergency.
Other health problems in Leopard Geckos
Tail drop
Leopard geckos can drop their tail when grabbed or frightened. It regrows, thicker and smoother, in a few months. Keep the stump clean.
What it looks like in a Leopard Gecko:
- Tail detached, wound at the base
- Regrowing tail that looks bulbous
When to see a vet: Any change that lasts more than a day or two, or anything that worries you.
When it is an emergency: Collapse, difficulty breathing, uncontrolled bleeding, or severe pain is always an emergency.
Warning signs to watch for in a Leopard Gecko
These are the early signals owners most often miss, or dismiss as age:
- Thinning tail
- Rubbery jaw or bent limbs
- No droppings for a week
- Toe tips turning dark
- An eye held shut
Leopard Gecko lifespan: what is normal
Fifteen to twenty years is normal for a leopard gecko, and mid-twenties happens. The big shorteners are the ones that show up in the first few years: no calcium or UVB (metabolic bone disease), a loose substrate (impaction), and a parasite picked up before you ever got them (cryptosporidiosis). A gecko that clears those hurdles usually lives a long, uneventful life and dies of old age or organ failure in its late teens.
Captive lifespans have risen as sand substrates and unsupplemented insects have gone out of fashion; a gecko bought in the 1990s was lucky to reach ten.
Genetic factors
Some morphs (notably enigma) carry a neurological condition called enigma syndrome that causes circling and head tilting. Otherwise, health is mostly about care rather than genetics.
What Leopard Geckos usually die from
Knowing what typically ends a Leopard Gecko's life is not morbid. It tells you which of the symptoms above deserve the fastest response.
- Parasites (cryptosporidium): Chronic wasting that resists treatment.
- Metabolic bone disease: Advanced cases cannot eat or move.
- Impaction: Usually from loose substrate.
- Egg binding: In breeding-age females.
- Old age: Well-kept leopard geckos live 15 to 20 years.
When it may be time: from managing symptoms to saying goodbye
Some of the conditions above (metabolic bone disease, impaction, and cryptosporidiosis) are managed for years. Each one, though, has a point where treatment prolongs the decline rather than the life. If you are reading this page because your Leopard Gecko is older and the bad days are starting to outnumber the good, that is worth saying plainly: you may not be looking for a diagnosis anymore. You may be looking for permission.
Signs the balance has shifted in a Leopard Gecko:
- A tail that has thinned to the width of a pencil, or thinner than the neck
- Refusing food for more than a month while losing weight (brumation without weight loss is normal)
- Lying flat on the floor of the tank instead of resting in a hide
- Eyes sunken or held shut, with the skin over the hips wrinkled and loose

If you are weighing costs and options, the pet end-of-life services guides by city cover in-home euthanasia and cremation prices, and the coping with losing a Leopard Gecko guide is there for afterward.
Preventive care for Leopard Geckos
- Dust feeder insects with calcium at every feeding and calcium with D3 or a multivitamin on a schedule
- Use paper towel, tile, or a solid substrate rather than sand
- Provide a humid hide with damp moss for shedding
- Quarantine new geckos and have a fecal test done by a reptile vet
- Weigh monthly; the tail is the fuel gauge

If this has stopped being about symptoms
Many people land here when their Leopard Gecko is old or ill and they are trying to work out whether what they are seeing is the end. If that is you, the health details above matter less than the question underneath them.

- What are the signs a Leopard Gecko is dying?
- The signs that a Leopard Gecko is nearing the end are refusing food and water, being unable to stand or get to the bathroom without help, pain that medication no longer reaches, withdrawing from the family, and more bad days than good over two weeks. Our when-to-say-goodbye guide for the Leopard Gecko walks through the quality-of-life scale vets use and what euthanasia involves.
- What vaccinations does my Leopard Gecko need?
- Core vaccines are essential for all Leopard Geckos. Your vet will recommend additional vaccines based on your pet's lifestyle, location, and risk factors. Keep vaccination records current and follow the recommended schedule.
- How do I know if my Leopard Gecko is in pain?
- Leopard Geckos often hide pain. Watch for: changes in appetite, reluctance to move, unusual posture, excessive licking of one area, withdrawal, aggression when touched, panting (in cats), or changes in sleep patterns. Any significant behavior change warrants a vet visit.
