Crested Geckos have gained popularity as fascinating and low-maintenance pets in recent years. These unique reptiles are native to New Caledonia and are treasured for their striking appearance and docile nature. However, like any living creature, Crested Geckos are susceptible to certain diseases that can affect their health and well-being. In this blog, we will explore the common diseases that Crested Geckos may carry, their causes, symptoms, prevention, and treatment options.

Common Diseases in Crested Geckos


Crested Geckos are enchanting reptiles that have captured the hearts of many pet owners. However, like any living creature, they are susceptible to certain diseases that can impact their health and well-being. Understanding the common diseases that Crested Geckos may carry is essential for providing them with the best possible care. 

In this section, we will explore some of the most prevalent diseases in Crested Geckos, including Metabolic Bone Disease (MBD), Mouth Rot (Stomatitis), and parasitic infections. By familiarizing ourselves with these diseases, their causes, symptoms, and prevention methods, we can ensure the overall health and longevity of our beloved Crested Gecko companions.

Metabolic Bone Disease (MBD)

Metabolic Bone Disease is a prevalent condition among Crested Geckos caused by a lack of calcium, vitamin D3, or an imbalance in their diet. Insufficient calcium intake affects bone development and overall skeletal health. Symptoms of MBD may include tremors, soft or misshapen bones, difficulty in climbing, and fractures. 

To prevent MBD, it is crucial to provide a well-balanced diet, including calcium and vitamin D3 supplements, and ensure proper lighting and temperature in their habitat. In severe cases, veterinary intervention is necessary, and treatment may involve calcium injections and dietary adjustments.

Mouth Rot (Stomatitis)

Mouth Rot, also known as stomatitis, is a bacterial or fungal infection that affects the oral cavity of Crested Geckos. It can occur due to poor oral hygiene, improper diet, or injuries to the mouth. Signs of stomatitis include swollen gums, redness, ulcers, excessive saliva production, and a reluctance to eat. Treatment for mouth rot typically involves a combination of antifungal or antibacterial medications, oral rinses, and improving the gecko’s habitat conditions. Regular cleaning of their enclosure and ensuring a balanced diet can help prevent mouth rot.

Parasitic Infections

  • Internal Parasites

Internal parasites, such as roundworms or pinworms, can infect Crested Geckos through contaminated food or exposure to infected animals. These parasites can cause weight loss, diarrhea, lethargy, and poor appetite. A fecal examination conducted by a reptile veterinarian is necessary to diagnose and identify the specific type of internal parasites. Treatment involves administering appropriate anthelmintic medications, ensuring hygienic husbandry practices, and regularly disinfecting the enclosure.

  • b. External Parasites

Crested Geckos can also be affected by external parasites, including mites and ticks. These tiny pests can cause irritation, skin damage, and stress to the gecko. Regularly inspecting the gecko’s skin and habitat is essential to identify the presence of external parasites. Treatment often involves isolating the affected gecko, manual removal of parasites, and using reptile-safe topical treatments. Maintaining a clean environment and minimizing contact with potential carriers can help prevent external parasitic infestations.

Other Health Issues in Crested Geckos


While common diseases like Metabolic Bone Disease and Mouth Rot receive significant attention, it’s important to be aware of other health issues that can affect Crested Geckos. In this section, we will explore some additional health concerns that may arise, including skin conditions, respiratory infections, and egg binding. 

These issues can impact the well-being of your Crested Gecko and require proper care and attention. By understanding the signs, causes, and preventive measures associated with these health issues, you can provide a comfortable and thriving environment for your gecko. Let’s delve into these lesser-known but significant health concerns that every Crested Gecko owner should be aware of.

Skin Conditions

Skin conditions, such as shedding problems, dermatitis, and infections, can occur in Crested Geckos. Inadequate humidity levels or incomplete shedding can lead to retained shed, which can constrict blood flow and cause serious complications. Dermatitis and infections may result from injuries, improper hygiene, or environmental factors. 

Providing appropriate humidity levels, offering moist hides during shedding, and keeping the enclosure clean and well-maintained can help prevent skin-related issues. In case of dermatitis or infections, veterinary care may be necessary to determine the underlying cause and administer suitable treatment.

Respiratory Infections

Respiratory infections are common in Crested Geckos and can be caused by factors such as inadequate ventilation, improper temperature, or exposure to pathogens. Symptoms of respiratory infections include wheezing, open-mouth breathing, nasal discharge, and lethargy. Prompt veterinary attention is crucial for diagnosing and treating respiratory infections in Crested Geckos. Treatment may involve antibiotics, supportive care, and improving the gecko’s habitat conditions to prevent further respiratory issues.

Egg Binding

Female Crested Geckos may experience egg binding, a condition where they are unable to lay their eggs. This can be caused by factors such as calcium deficiency, improper nesting conditions, or genetic predisposition. Signs of egg binding include a distended abdomen, lethargy, and straining. If left untreated, egg binding can be life-threatening for the gecko. 

Treatment may involve providing a warm and humid environment, gentle massage, and veterinary assistance for egg extraction if necessary. Proper nesting sites and ensuring adequate calcium supplementation can help reduce the risk of egg binding.

Preventive Care for Crested Geckos

Prevention plays a vital role in maintaining the health and well-being of Crested Geckos. Here are some preventive care measures you can take:

Creating a suitable habitat:

  • Maintain appropriate temperature and humidity levels within the enclosure.
  • Provide a variety of hiding spots, climbing structures, and branches for exercise and mental stimulation.
  • Ensure a clean and hygienic environment by regularly cleaning and disinfecting the enclosure.

Regular veterinary check-ups:

  • Schedule routine examinations with a reptile veterinarian to monitor your gecko’s overall health.
  • Fecal tests should be conducted to detect any internal parasites and administer appropriate preventive medications.
  • Early detection of potential health issues through regular check-ups can prevent complications and improve outcomes.


While Crested Geckos are generally hardy and resilient, they are still susceptible to various diseases and health issues. By familiarizing yourself with the common diseases that Crested Geckos may carry, their causes, symptoms, and preventive measures, you can provide them with the best possible care. 

Responsible pet ownership entails regular monitoring of your gecko’s health, providing suitable habitat, and seeking veterinary care promptly when necessary. By taking these proactive steps, you can ensure the longevity and well-being of your beloved Crested Gecko companion.
