My leopard gecko ate a big worm. Is it choking or okay?

Geckos are not toxic, but may carry parasites that could be harmful. At worst, you may see some temporary stomach upset. Consider a short fast followed by a b;and diet fed in small, frequent amounts until symptoms resolve. Transition slowly to the regular diet afterwards. My condolences on the loss of your gecko.

If they were refrigerated, it may not cause any harm. The concern is them eating rotting prey. Monitor for lethargy, loss of appetite, loose droppings or regurgitation. You may end up taking them to your veterinarian or a vet experienced in treating reptiles for exams and supportive care if they develop any of the symptoms mentioned above.

I think that you are right to be concerned about Geo. With the previous lack of humidity and inappropriate husbandry, I would be worried that she may have an impaction. When impactions occur in the intestinal tract or colon, it does not allow additional food to pass through the intestines. This eventually will lead to regurgitation. This is a common finding in geckos that have not had appropriate husbandry. The regurgitation may also be due to her not feeling well - just like when we get sick, reptiles can become nauseous. This is less of a specific sign and can be due to numerous diseases. I would recommend taking Geo in for evaluation by a veterinarian. They can perform a thorough physical examination and see if they suspect an impaction based on palpation of the coelom (feeling the belly). Depending on what they find, they may recommend diagnostics or treatments for Geo. I know that you have already increased the humidity, but it may also be a good idea to soak Geo in 85-90 F water for 15-20 minutes twice daily. This may encourage her to drink (although many leopard geckos do not like to soak, even though it is good for them :) ) and hydrate. I hope this gives you a place to start, and I hope that Geo feels better soon!

This may simply be how he eats, especially in the absence of other symptoms. Confirm proper environmental parameters and monitor him. Symptoms that should be addressed by your veterinarian or a vet experienced in treating reptiles may include lethargy, decrease or loss of appetite, weight loss, abnormal stool or straining to defecate.

Kota may have an impaction. The main cause of impaction is sand or other loose substrate (Gravel, walnut shell, quartz, ect.) that your gecko might ingest during feeding. The ingested substrate doesn't digest like the rest of the food in its stomach, and either forms a mass in the stomach, or passes into the intestines and creates a blockage. This blockage prevents the gecko from pooping, and the gecko will stop eating. The sick leopard gecko will grow weak, and eventually die if not treated. Early signs of impaction are lethargy, failure to eat or poop and a bloated belly. A warm soak and a drop of olive oil or mineral oil in the mouth may help the gecko to pass the impacted matter. I recommend a warm soak for 5 minutes twice a day. You can give one drop the oil by mouth to see if that will help the impaction pass. DO NOT force the oil down the throat as you may cause her to aspirate the oil into the lungs and that would be disastrous! Just put the drop right inside the mouth. If the impaction isn't passed, the gecko will develop a thin tail as it loses weight, barely opened eyes, increasing lethargy, and a dark blue spot on his/her side. If any of these more extreme symptoms occur, rush your leopard gecko to a vet IMMEDIATELY. Impaction CAN KILL YOUR GECKO. On rare occasion, there are other things that can cause impaction. Sometimes, part of an undigested mealworm or other hard-exoskeleton insect can get lodged in your gecko's intestines. Sometimes a cyst will form inside your gecko's stomach or intestines and cause a blockage. However, that is an extremely rare occurrence. I hope this helps. Best wishes.

Check temps in the cage. Low temps can affect appetite in reptiles. If temps are normal, make sure the mealworms are appropriately sized, no bigger than the space between the eyes. You can also offer freshly molted mealworms which have less chitin and are easier to digest. Other options include crickets, dubia roaches and phoenix worms.

Check the temperature in the enclosure. Low temps can affect appetite and digestion in reptiles. Soak her in a warm 50/50 solution of water and unflavored PediaLyte to provide warmth and hydration. Confirm appropriately sized prey, no bigger than the space between the eyes. You can offer crickets, dubia roaches, mealworms and phoenix worms. Gut load all prey for 24 hours prior to offering to maximize nutritional value. Submit a stool sample to your veterinarian to diagnose intestinal parasites. If she will allow, look in and around her mouth for any signs of injury or infection. This may include redness, swelling, discharge or bleeding. If you see anything suspicious, have her physically examined by your veterinarian or a vet experienced in treating reptiles to diagnose and treat any underlying causes.
