Leopard Gecko Health Problems: Common Issues & Prevention (2026)

While leopard geckos are generally hardy reptiles, they can develop health issues when husbandry is incorrect or as they age. Early recognition of health problems dramatically improves treatment outcomes. This guide covers the most common leopard gecko health issues, their symptoms, prevention strategies, and when veterinary care is essential.

infoPrevention Is Key

Most leopard gecko health problems are caused by improper husbandry: wrong temperatures, poor diet, inadequate supplementation, or incorrect humidity. Maintaining proper care prevents the vast majority of health issues. When problems do occur, early veterinary intervention leads to better outcomes.

Metabolic Bone Disease (MBD)

Metabolic bone disease is one of the most common and preventable health problems in leopard geckos. It occurs when calcium or vitamin D3 is insufficient, causing the body to leach calcium from bones to maintain blood calcium levels.

MBD Symptoms

check_circleSoft, rubbery jaw (early sign)
check_circleBowed or bent legs
check_circleDifficulty walking, dragging body
check_circleTrembling or twitching
check_circleLethargy and weakness
check_circleReluctance to eat
check_circleSpinal deformities in severe cases

MBD Prevention

Dust feeder insects with calcium plus D3 at every feeding. Provide a dish of plain calcium for self-regulation. Consider low-level UVB lighting for natural D3 synthesis. Ensure proper temperatures for calcium absorption (digestion requires warmth). Gut-load feeders with calcium-rich vegetables.

warningMBD Is a Veterinary Emergency

If you suspect MBD, see a reptile veterinarian immediately. Early-stage MBD is often reversible with treatment. Advanced MBD causes permanent deformities and can be fatal. Do not attempt to treat severe MBD at home.

Impaction

Impaction occurs when indigestible material blocks the digestive tract. Common causes include loose substrates (especially calcium sand), feeder insects too large to digest properly, or dehydration causing fecal matter to harden.

Impaction Symptoms

check_circleNo bowel movements for extended periods
check_circleStraining to defecate without results
check_circleLoss of appetite
check_circleLethargy
check_circleDark spot visible on belly (impacted material)
check_circleBloated abdomen
check_circleRegurgitation

Impaction Prevention and Treatment

Use safe substrates (tile, paper towels, or properly managed bioactive). Never use calcium sand, walnut shells, or gravel. Feed appropriately sized insects (no larger than the space between the gecko eyes). Maintain proper temperatures, as cold geckos cannot digest food properly. For suspected impaction, try warm baths (85°F) and gentle belly massages. If symptoms persist beyond 2-3 days, see a vet.

Respiratory Infections

Respiratory infections (RI) typically result from temperatures that are too low, excessive humidity, or drafty enclosures. Bacteria or fungus can colonize the respiratory tract when conditions are unfavorable.

RI Symptoms

check_circleWheezing or clicking sounds when breathing
check_circleBubbles around nose or mouth
check_circleOpen-mouth breathing
check_circleMucus discharge from nose
check_circleLethargy and loss of appetite
check_circleExtended time on warm side (attempting to self-treat)

RI Treatment

Respiratory infections require veterinary treatment with antibiotics. Raise temperatures to the upper end of the acceptable range. Reduce humidity in the main enclosure. Ensure proper ventilation without drafts. Do not delay treatment, as RI can progress rapidly and become fatal.

Stuck Shed (Dysecdysis)

Retained shed occurs when old skin does not come off completely. While not immediately life-threatening, stuck shed on toes and tail tip can cut off circulation and cause tissue death if not addressed.

Prevention and Treatment

Maintain a humid hide with damp substrate at all times. Check your gecko after every shed, especially toes and tail tip. Treat stuck shed with 10-15 minute warm water soaks followed by gentle removal with a wet cotton swab. For stuck eye caps, see a veterinarian rather than attempting removal yourself.

Internal Parasites

Many leopard geckos, especially those from pet stores or unclear sources, carry internal parasites like pinworms or coccidia. Low-level infections may cause no symptoms, but stress or immune suppression can allow parasite populations to explode.

Parasite Symptoms

check_circleWeight loss despite eating well
check_circleChronic diarrhea or abnormal feces
check_circleVisible worms in feces (pinworms)
check_circleBloated abdomen
check_circleLethargy
check_circlePoor body condition despite good husbandry

Diagnosis requires a fecal exam by a veterinarian. Treatment involves anti-parasitic medications dosed by weight. New geckos should have a fecal test within the first few weeks of ownership. Annual fecals are recommended for all geckos.

Mouth Rot (Stomatitis)

Stomatitis is a bacterial infection of the mouth tissues. It often begins after a mouth injury, feeding hard-shelled insects, or from systemic illness weakening the immune system.

Mouth Rot Symptoms

check_circleRedness or swelling around the mouth
check_circleCheesy or cottage-cheese-like material in mouth
check_circleExcessive drooling
check_circleRubbing face on objects
check_circleRefusal to eat
check_circleBad smell from mouth area

Mouth rot requires veterinary treatment with antibiotics and often antiseptic rinses. Left untreated, it spreads and can become systemic. Early treatment leads to full recovery.

Cryptosporidiosis (Crypto)

warningSerious and Contagious

Cryptosporidiosis is a serious parasitic infection that is highly contagious between reptiles and currently has no cure. Infected geckos become carriers for life. Strict quarantine and testing are essential when adding new geckos to a collection.

Crypto causes progressive weight loss, stick tail (severe muscle wasting), regurgitation, and eventual death. There is no cure, only supportive care. Prevent by purchasing from reputable breeders who test for crypto and quarantining all new animals.

When to See a Veterinarian

check_circleAny breathing problems (wheezing, open mouth, bubbles)
check_circleTrembling, twitching, or difficulty walking
check_circleNo eating for more than 2 weeks (adults) or 1 week (juveniles)
check_circleVisible injuries, wounds, or prolapse
check_circleSwelling anywhere on the body
check_circleAbnormal feces for more than a few days
check_circleRapid or dramatic weight loss
check_circleEye problems (swelling, discharge, stuck caps)
check_circleAny condition that worsens despite husbandry corrections

Find a reptile-experienced veterinarian before you need one. Not all vets are comfortable with reptiles. Exotic or reptile-specific veterinary clinics are ideal. The Association of Reptile and Amphibian Veterinarians (ARAV) has a vet locator tool.

Frequently Asked Questions

How do I know if my leopard gecko is sick?expand_more

Watch for changes from normal behavior: lethargy, loss of appetite, weight loss, abnormal feces, breathing problems, or unusual posture. A gecko that stops eating, hides constantly (even at night), or shows physical symptoms like swelling or discharge needs attention.

Can leopard geckos recover from MBD?expand_more

Early-stage MBD is often reversible with proper treatment (calcium, D3, and sometimes veterinary intervention). However, bone deformities that have already formed cannot be reversed. Prevention is far better than treatment.

How often should I take my gecko to the vet?expand_more

A new gecko should have a wellness exam within the first week or two. After that, annual checkups are ideal, including a fecal parasite test. Between regular visits, see a vet whenever you notice concerning symptoms.

What should I have in a leopard gecko first aid kit?expand_more

Useful items include: unflavored Pedialyte (for hydration), pure unsweetened applesauce (for syringe feeding if needed), Betadine for minor wound cleaning, tweezers, cotton swabs, a digital scale, and your reptile vets contact information.

Prevention Through Good Husbandry

The vast majority of leopard gecko health problems are preventable through proper husbandry. Maintain correct temperatures, supplement appropriately, use safe substrates, and provide a clean environment. When health issues do occur, early recognition and veterinary care give your gecko the best chance of recovery. Build a relationship with a reptile vet before emergencies arise, and do not hesitate to seek professional help when something seems wrong.
