Why is my overweight leopard gecko weak, not eating, with a tail rash?

Updated On September 23rd, 2025

Pet's info: Reptile | Gecko | Male | unneutered | 8 years and 2 months old

My leopard gecko has not been eating the past couple weeks. He is quite overweight but has lost some of it from this. He seems much weaker and out of energy. I had to help him shed the other day as he was having difficulty. He also has a large red area on his tail that looks to be some sort of rash or infection. Thank you for any help.

Thanks for reaching out about Gexter and including photos. Review diet to include a wide variety of insects, all being gut loaded with fresh vegetables. He does appear overweight with a fat tail and legs. These are only the external signs of obesity, what can not be seen is the internal damage to the liver (hepatic lipidosis) and possible heart disease. The red area/rash could be due to a compromised immune system and secondary infection, metabolic disorder (liver, kidney) or other problem. A veterinary visit is needed to assess and provide a diagnostic/treatment plan. Remove any substrate (soil, bark) that could irritate the lesion and replace with clean cloth or towels. Review and correct diet and husbandry. Try offering water and then a moistened food via a syringe. Good luck.
