Leopard Gecko Common Health Issues: A Comprehensive Care Guide

If your leopard gecko looks a bit off, it's natural to worry. These geckos are hardy pets. But even the healthiest ones can get sick without proper care. Knowing the most common health problems helps you act fast — and that can save your gecko's life.

Common Leopard Gecko Health Problems

Leopard geckos are popular for good reason. They're easy to handle and don't need much space. But health problems can sneak up on any gecko owner. Here are the main issues to watch for:

• Weak bones (metabolic bone disease)
• Breathing problems (respiratory infection)
• Gut issues (impaction and parasites)
• Skin and shedding problems
• Egg binding (in female geckos)

Each of these is preventable with the right setup and routine care.

Weak Bones (Metabolic Bone Disease)

Weak bones is the most serious and common health problem in leopard geckos. It happens when your gecko doesn't get enough calcium or vitamin D3. Without these nutrients, bones grow soft and may break or deform.

Signs to Look For

• Legs or tail look bent or kinked
• Your gecko moves slowly or stumbles when walking
• Muscle shaking or twitching, especially after handling
• Swollen jaw or limbs
• Extreme lethargy

This condition gets worse fast. If you notice any of these signs, act right away.

How to Prevent It

Weak bones are almost entirely preventable. Here's what to do:

1. Dust feeder insects with calcium powder before every feeding. Zoo Med ReptiCalcium with D3 is a reliable and affordable option trusted by reptile keepers worldwide.
2. Add a UVB light to your gecko's enclosure. It helps them produce vitamin D3 naturally. A quality reptile UVB bulb like the Arcadia 6% T5 is widely recommended by herpetologists.
3. Keep a calcium dish in the enclosure at all times so your gecko can self-regulate.

These three steps together cut the risk of weak bones dramatically.

Treatment

If your gecko already has weak bones, see a reptile vet right away. The vet can give calcium and vitamin D3 injections. They'll also review your setup and suggest changes. Early treatment leads to full recovery in many cases. Don't delay — the later you treat it, the harder recovery gets.

Breathing Problems (Respiratory Infections)

Respiratory infections are common when a gecko's enclosure is too humid, too cold, or poorly ventilated. Bacteria or viruses can infect the lungs and airways.

Signs to Look For

• Wheezing or clicking sounds when breathing
• Runny nose — clear or cloudy discharge
• Open-mouth breathing or gasping
• Less activity than usual, won't eat
• Tilting the head up to breathe easier

Don't wait to see if it gets better on its own. These symptoms mean your gecko needs help.

Prevention

Keep your gecko's enclosure clean and dry. The right conditions are:

• Humidity: 30–40% (no higher)
• Warm side temperature: 88–92°F
• Cool side temperature: 74–80°F

A reptile digital thermometer and hygrometer combo makes it easy to monitor both at a glance. You'll catch problems before they cause illness.

Treatment

If your gecko has a respiratory infection, take it to a reptile vet. The vet will prescribe antibiotics suited for reptiles. They may also help you adjust the enclosure setup to prevent a repeat infection.

Gut Problems

Gut problems can be serious and sometimes life-threatening. The two main types are blockages and parasites.

Blockages (Impaction)

A blockage happens when a gecko swallows substrate — the material lining the enclosure floor. Fine sand and small gravel are the biggest culprits. The material builds up in the gut and blocks digestion entirely.

Signs include:

• No bowel movements for several days
• Visibly swollen belly
• Won't eat
• Straining when trying to pass waste

The best fix is prevention. Don't use loose sand or gravel with young or small geckos. Paper towels, ceramic tile, or reptile carpet are much safer choices. They're easy to clean and carry zero impaction risk.

If you think your gecko is impacted, see a vet urgently. The vet may recommend warm soaks, gentle abdominal massage, or in severe cases, medical intervention.

Parasites

Leopard geckos can carry internal parasites like roundworms or pinworms. Wild-caught geckos are at higher risk, but even captive-bred animals can develop them over time.

Signs include:

• Rapid weight loss despite eating
• Poor appetite or refusing food entirely
• Loose or bloody stools
• Dull eyes and sunken belly

A fecal test from your reptile vet will confirm parasites. Treatment usually means a short course of deworming medication. It's quick and effective when caught early.

Skin and Shedding Problems

Leopard geckos shed their skin regularly. This process is completely normal. But sometimes the old skin doesn't come off cleanly. We call this stuck shed.

Why Stuck Shed Happens

Low humidity is the most common cause. Dry air makes old skin stiff and hard to remove. Common problem spots include:

• Toes
• Eyelids
• Tail tip
• Around the head and neck

When skin stays stuck, it tightens over time like a rubber band. This can cut off circulation to toes or the tail tip. Toe loss is a real risk if stuck shed isn't handled quickly.

How to Handle It

Never pull dry shed off your gecko — it can cause bleeding and injury. Instead:

1. Set up a humidity hide: a small covered container filled with damp sphagnum moss. Let your gecko sit in it before and during shed.
2. Offer a warm soak: fill a shallow dish with lukewarm water and let your gecko sit for 10–15 minutes. The moisture loosens stuck skin.
3. Use a wet cotton swab to gently work off stubborn patches. Never force it.

A reptile moist hide available year-round in the enclosure prevents most stuck shed problems entirely. Keep the moss inside damp during shedding periods.

Egg Binding in Female Geckos

Egg binding only affects female geckos. It happens when a female can't lay her eggs normally. This is life-threatening if not treated fast.

Signs to Look For

• Small round bumps visible through the belly skin
• Digging frantically in the enclosure but not producing eggs
• Straining with no eggs released
• Loss of appetite and energy
• Swollen belly that doesn't go down

What to Do

Always provide a laying box for female geckos. Use a container filled with moist coco fiber or vermiculite. Make sure it's dark inside and deep enough for her to dig comfortably.

If your female has been digging for more than 24–48 hours with no eggs produced, take her to a reptile vet right away. The vet can give an oxytocin injection to stimulate laying. In serious cases, surgery may be needed. Don't wait — egg binding turns fatal quickly without treatment.

When to See a Reptile Vet

Leopard geckos hide pain and illness well. By the time symptoms show clearly, the problem is often already serious. Don't wait too long to get help.

See a vet right away if your gecko:

• Hasn't eaten for more than 2 weeks
• Shows signs of any condition covered in this guide
• Is losing weight rapidly
• Has unusual lumps, swelling, or discharge
• Seems lethargic for more than a few days in a row

Finding a vet who specializes in reptiles matters. General vets may not have the right tools or experience. Look for one listed with the Association of Reptilian and Amphibian Veterinarians (ARAV).

Keeping Your Gecko Healthy: Quick Checklist

Most health problems in leopard geckos come down to basic care. Get the setup right and you'll avoid most issues:

• Dust insects with calcium + D3 powder at every feeding
• Provide a UVB light for natural vitamin D3 production
• Keep humidity at 30–40% and temperatures in the correct range
• Use safe substrate — no loose sand or small gravel
• Keep a humidity hide in the enclosure during shedding periods
• Watch your gecko daily for behavior or appearance changes
• See a reptile vet at the first sign of trouble

Healthy geckos are active, have bright eyes, and eat regularly. If something seems off, trust your instincts and act.
