Even with the best of care, your beloved leopard gecko may get sick. Here are a few things to watch out for and what you can do to prevent illness. If you're asking, "How do I know if my leopard gecko is sick" or "What do I do if my leopard gecko is sick?" then please continue reading:\n\n\n\n\n\n\n\nImpaction\n\n\n\nThis is one of the most common things that may happen to your gecko. Impaction happens when your gecko eats something that gets stuck (or impacted) in its digestive tract. The impaction will block the normal 'flow' of the digestive process. In other words, your gecko can't poop.\n\n\n\nCause of Impaction\n\n\n\nSand substrate is a common cause of impaction,\u00a0 especially with small geckos. This is why we don't recommend using sand, calcium sand, or loose materials as a substrate. Food items that are too large for your gecko to digest may also cause impaction. As a quick guide, you should offer insects no larger than the space between your gecko's eyes.\n\n\n\nTreating Impaction\n\n\n\n\u00a0A warm bath and a gentle belly rub may help soften the stool and move the impacted material through the digestive tract. Raising the temperature a few degrees will help to raise your gecko's metabolism which may also help move things along. If the impaction remains, it may require a trip to the vet and surgery to remove the blockage.\n\n\n\nMetabolic Bone Disease (MBD)\n\n\n\nMetabolic Bone Disease may occur if your leopard gecko does not get enough calcium. \u00a0 If your leopard gecko is not getting enough calcium, the body will start leaching calcium from the bones. This could cause skeletal deformities and weak bones.Your gecko may have difficulty walking or its legs may appear flimsy or twisted. Or, most probably, both.If you want to see an example of a leopard gecko with MDB, you can check out the poor lizard in the leopard gecko rescue video below:\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=9UHX_XyM42c\nYou can see the effects of MBD in a leopard gecko this video clip from Nature's Edge Wildlife and Reptile Rescue\n\n\n\nThere is no 'cure' for MDB, and the effects are not reversible. You can stop the disease from becoming more advanced with proper nutrition and dietary supplements.\n\n\n\nHemipenile Prolapse\n\n\n\nI've had fairly good luck with the overall health of my leopard gecko, but this one scared me. One day when our gecko, Dude, was cleaning himself, I noticed an oddly colored bit of skin underneath his tail. Further inspection revealed he had an angry looking red bit of skin protruding from one of the slits at the base of this tail. It did not look healthy. \n\n\n\nUnfortunately, my favorite vet (who happened to specialize in exotics) had left our local animal hospital. I had to call around to several local vets to find one that could diagnose and treat reptiles. (Note that all veterinary practices may not have someone on staff that treats reptiles.) It was winter, so I packed our gecko, Dude, up in a box with a small heat pack (warm, not hot), and headed to the vet.\n\n\n\nHe was diagnosed with a Hemipenile Prolapse, which is every bit as scary as it sounds. The hemipenis is the male leopard gecko's reproductive organ, which belongs on the inside when they are not mating. When exposed for extended periods, it can dry out and turn necrotic if not corrected. If not treated, it could be fatal. \n\n\n\nAfter consulting with the vet, the organ was reinserted. I was given instructions on how to guide things back into place should it slip out again, and the vet was not available. The vet was kind enough to provide supplies and prescribe an antibiotic cream.\u00a0 I can tell you both Dude and I felt better with all of his bits back inside where they should be.\n\n\n\nHemipeinile Prolapse is common among breeding geckos, but Dude has always lived as a bachelor. I'm still curious how it happened, but figure it's best for both of us if I don't ask him too many questions.\n\n\n\nStick Tail or Skinny Tail\n\n\n\nSkinny Tail, or Stick Tail are terms for weight loss in your gecko. This isn't the good kind of finally hitting your goal of shedding a few pounds kind of weight loss, but a sign your leopard gecko is sick or malnourished. Or both.\n\n\n\nWhen a gecko loses weight and body mass, often times its tail will start to get thinner as it burns through its fat store. \n\n\n\nLook for these signs of Stick Tail:\n\n\n\nTail is thinner than your gecko's bodyTail is straight with little curveTailbones are visible through the skinYour leopard gecko refuses food\n\n\n\nShould your leopard gecko's tail, at its widest point, become thinner than its body, you should be mindful of your gecko's diet and how much nutrition it is getting. When the tail is more strait than curvy and begins to resemble a stick or you can see the tailbones through the skin, your gecko is in trouble. Simply feeding it more may not be the answer (and it may not want to eat.)\n\n\n\nThis could be serious and warrants a visit with a qualified exotics vet. The vet will most likely take fecal samples to test for parasites.\n\n\n\nA common cause of stick tail is that the gecko has picked up an intestinal protozoal parasite called Cryptosporidium, sometimes shortened to Crypto. Infected leopard geckos can pass the parasite on to others, even if they are not showing signs of the sickness themselves. Leopard geckos with crypto may refuse to eat or eat very little and may pass undigested food. \n\n\n\nYou'll want to quarantine a gecko with stick tail, and take it to a vet that specializes in exotics.\n\n\n\nIf the cause of the condition is parasites, your vet will most likely prescribe medication, which will get rid of the parasites and allow your gecko to start getting back to a healthy weight.\n\n\n\nLost or Dropped Tail\n\n\n\nIt may seem like a traumatic experience should your pet lose its tail (both for you and your lizard.)\u00a0 Generally, it will heal on its own, as it is designed to do.If you have substrate that may irritate or infect the wound, you'll want to get your gecko onto something like paper or paper towel while it is healing.\n\n\n\nIf your gecko lives in a tank with other geckos, you may want to isolate it for some time while it is healing.\n\n\n\n\nhttps:\/\/www.youtube.com\/watch?v=KXbV3x4PgXc\nYou can see what tail regeneration looks like in this time lapse video from Okie Pokey Hogs \n\n\n\nMake sure your leopard gecko is getting plenty to eat. It just lost its fat store, and needs calories and energy to sustain itself and grow back its tail.

Proper Nutrition Make sure your leopard gecko has a proper diet and some variety in the feeder insects offeredProvide the appropriate supplementsFood from Trusted Sources Insects caught in the wild could be carrying diseases or have been exposed to pesticides.\u00a0\u00a0 Buy your feeder insects from trusted sources, or breed your own. Check our Complete Feeding Guide here Proper Hygiene If you're handling your gecko and have been exposed to parasites or diseases, it is possible you could pass these to your gecko.\u00a0 This is especially true if you have other reptiles and move from handling one pet to the other. Washing your hands can greatly reduce the risk. Quarantine If you have multiple geckos in the same enclosure, it's important to isolate any of them should you suspect sickness.\u00a0 This will reduce the risk of the illness spreading. Similarly, you should quarantine new leopard geckos or breeding partners before introducing them to an enclosure housing other geckos. Proper Humidity and Shedding CareMake sure you have a most hide or mist your tank when your leopard gecko is ready to shedTake care with shed skin that remains behind, especially on the feet and toes\n\n\n\nRelated Post: Sickness and stress often go hand in hand.
