Metabolic Bone Disease (MBD) is a common health issue among captive reptiles, including chameleons. It’s a general term for a group of conditions related to deficiencies in calcium, Vitamin D3, or an imbalance in the ratio of calcium to phosphorus in the body. MBD can be serious and even fatal if not treated promptly.
Here are some key details about MBD:

Causes
The main cause of MBD is nutritional deficiency or imbalance.
Other factors, like poor diet, improper temperature and humidity, kidney disease, or parasites can also contribute to the development of MBD but a calcium deficiency is the most common cause.
Chameleons need a diet high in calcium and access to UVB light, which helps them synthesize the Vitamin D3 that is necessary for the absorption and metabolism of calcium.
If they don’t receive enough calcium, Vitamin D3, or if their diet has too much phosphorus compared to calcium, it can lead to MBD.
Symptoms
Signs of MBD can vary based on its severity and the specific type of MBD present. Common symptoms include:
- Weakness or lethargy
- Loss of appetite
- Swollen or rubbery limbs
- Twisted, bent, or fractured bones
- Difficulty moving, climbing, or holding onto branches
- Tremors, twitches, or spasms
- In severe cases, a curved spine or jaw deformities (“rubber jaw”)
Treatment
You treat a chameleon with MBD by fixing the underlying issues that contribute to the disease.
Here are the steps involved in treating MBD in chameleons:
- Providing enough calcium and vitamin D3 supplementation: Chameleons require adequate calcium and vitamin D3 for proper bone health. Calcium supplements, such as calcium powder or liquid, can be provided in their diet. Additionally, chameleons need access to appropriate UVB lighting, as it helps them synthesize vitamin D3.
- Changes to lighting (UVB): Ensuring that chameleons receive sufficient UVB exposure is crucial for their overall health and calcium metabolism. UVB light allows chameleons to produce vitamin D3 in their skin, which is essential for calcium absorption. Proper UVB lighting, such as a UVB bulb or tube designed for reptiles, should be provided in their habitat.
- Changing habitat conditions to support mobility and recovery: It’s important to create a suitable habitat for chameleons that allows them to move freely and exercise. This includes providing appropriate branches, perches, and climbing structures. A well-designed habitat can help chameleons regain strength and improve their bone health.
- Veterinary interventions: In severe cases of MBD, veterinary care may be necessary. Veterinarians may administer fluid therapy to address dehydration and correct imbalances, assist with feeding to ensure proper nutrition, and provide supportive care. In some cases, surgery may be required to address fractures or other skeletal issues.
It’s crucial to consult with a qualified reptile veterinarian for an accurate diagnosis and tailored treatment plan for chameleons with metabolic bone disease. They can provide guidance on specific dietary and environmental adjustments needed to address MBD and improve the chameleon’s overall health.
Prevention
The best way to prevent MBD is by providing a proper diet and habitat for your chameleon.
This includes giving your chameleon a balanced diet with adequate calcium, regularly dusting their food with calcium and multivitamin supplements, access to UVB light, and maintaining correct temperatures and humidity levels in the enclosure. Regular veterinary check-ups can also help detect early signs of MBD and other health issues.
MBD is a serious condition, and if you suspect your chameleon is suffering from it, you should seek veterinary care immediately.
The sooner MBD is diagnosed and treated, the better the chances for recovery.
However, even with treatment, severe cases of MBD can cause permanent damage. That’s why prevention through proper diet and care is the best strategy.
