Cause of Prolapse
Occasionally with a leopard gecko reproductive tract will prolapse which causes health issues and can be fatal if not treated.
Prolapse occurs when a piece of organ or tissue is sticking out from the body and can't be reinserted naturally. The only place (usually) that you find prolapse in leopard geckos is around the the vent area. This is usually caused by mating (females), egg-binding parasites or your leopard geckos pushing something hard out. This is usually caused by impaction by sand or food which is too big and a leopard gecko is forcing it out.
Curing a Prolapse
One of the methods that you commonly find on the internet to remedy this is soaking the leopard gecko in a warm solution of dissolved sugar and water overnight. This is supposed to cause retraction of the prolapse making it easier to reinsert and if this doesn't work then seek help from a qualified reptile veterinarian. Don't try and do this as it doesn't always work and many people find it makes the prolapse worse if the correct doseage isn't used. The best course of action is to take the leopard gecko directly to a vet, and remove anything that could get into the prolapse such as sand. Keep your leopard gecko on paper towels and the prolapse should be kept moist with warm water. You should NEVER attempt to reinsert a prolapse back into your leopard gecko as it can harm your leopard gecko internally.
