One of the most common and concerning diseases in bearded dragons is Metabolic Bone Disease (MBD), a condition that can have severe consequences if not addressed early on.
In this article, we’ll delve into the causes, symptoms, prevention, and treatment of MBD in bearded dragons, equipping you with the essential knowledge to give your beloved pet the best care possible.
What is Metabolic Bone Disease in Bearded Dragons?
Metabolic Bone Disease, or MBD, is a broad term that refers to a group of disorders affecting the bones and skeletal system of reptiles, including bearded dragons. These disorders are generally caused by an imbalance in the levels of calcium, phosphorus, and vitamin D3 in the body. When not properly regulated, these imbalances can lead to weak, brittle bones that are prone to fractures, deformities, and other health complications.
Metabolic bone disease is also known as fibrous osteodystrophy, osteomalacia, secondary nutritional hyperparathyroidism, osteoporosis, or rickets, commonly called MBD.
The impact of MBD on a bearded dragon’s health can be quite severe. In the early stages, you may notice your bearded dragon showing signs of lethargy, loss of appetite, or difficulty moving.
As the disease progresses, their bones may become visibly deformed, making it difficult for them to walk, climb, or even eat. In extreme cases, MBD can lead to paralysis and, ultimately, death.
What Causes MBD in Bearded Dragons?
Understanding and addressing these causes of Metabolic Bone Disease in bearded dragons can make a significant difference in their overall health.
Let’s dive into the primary causes of MBD in bearded dragons and discuss how we can prevent this condition from affecting our beloved pets.
1. Inadequate Calcium Intake
One of the primary causes of MBD is a lack of calcium in a bearded dragon’s diet. Calcium plays a vital role in maintaining strong bones and a healthy nervous system. Without enough calcium, bearded dragons can suffer from weakened bones and other health issues.
Gut-loading insects with calcium-rich food and dusting insects with calcium powder before feeding them to your bearded dragon is the best way to meet your beardie’s calcium needs.
2. Insufficient Exposure to UVB Light
Another critical factor that contributes to MBD in bearded dragons is inadequate exposure to UVB light. Bearded dragons need UVB light to synthesize vitamin D3, which helps them absorb calcium from their diet. Without proper UVB exposure, bearded dragons cannot process calcium, leading to MBD.
Providing a high-quality UVB light source is crucial for preventing MBD. Place a UVB bulb within 12 inches of my bearded dragon’s basking area and ensure it covers at least two-thirds of the enclosure has been effective in ensuring proper UVB exposure.
3. Imbalanced Calcium-to-Phosphorus Ratio in the Diet
The calcium-to-phosphorus ratio in a bearded dragon’s diet is another important aspect of preventing MBD. An ideal ratio is 2:1 (calcium to phosphorus), as it allows for proper calcium absorption. A diet with an imbalanced ratio can lead to poor calcium absorption, ultimately resulting in MBD.
What can cause a calcium/phosphorous imbalance?
Poor calcium to phosphorous ratio can be caused by a number of factors, but the majority of them are related to poor husbandry. This can be as simple as not getting enough calcium or getting too much phosphorus in their diet, but there are a number of other factors at play.
Other dietary factors could include too much fat, which reduces calcium solubility, or foods that restrict calcium absorption. Oxalates, for example, bind to calcium and are excreted together in the intestine.
Vitamin D deficiency is another prevalent cause of low calcium levels. Vitamin D is required for calcium absorption. It allows calcium to pass through the duodenum’s membranes, where it can then be distributed throughout the body.
Vitamin D shortage isn’t usually a dietary problem. While reptiles can get a small amount of Vitamin D from their diet, they don’t absorb it very effectively.
Reptiles have their own metabolic pathways via which they create the vast bulk of what they require. The proper functioning of these pathways, however, requires constant UVA and UVB light exposure. As a result, poor or insufficient lighting is frequently blamed for MBD.
To maintain a balanced ratio, focus on offering a variety of calcium-rich foods, such as collard greens, mustard greens, and dandelion greens. Also avoid feeding my bearded dragon too many phosphorus-rich foods like spinach or beet greens, as they can hinder calcium absorption.
Recognizing the Symptoms of MBD in Bearded Dragons
Being vigilant about your bearded dragon’s health is essential in catching MBD early on. By monitoring for the physical signs and behavioral changes listed below, you can ensure that your beloved pet receives prompt attention and care.
Physical Signs
1. Soft or rubbery jaw and limbs: One of the first signs of MBD in bearded dragons is a soft or rubbery jaw. You may notice that your beardie’s jaw feels unusually pliable when gently touched. Similarly, their limbs may also feel weak and flexible.
2. Swollen or bowed limbs: If MBD progresses, you might observe that your bearded dragon’s limbs appear swollen or bowed. This is due to the weakening of their bones, which can lead to fractures and deformities.
3. Difficulty walking or moving: As MBD affects the skeletal structure of bearded dragons, they may struggle with movement. Watch for signs of your pet having trouble walking, climbing, or even holding their head up.
4. Twitching or tremors: Muscle twitching or tremors can be another sign of MBD. In my experience, one of my bearded dragons developed noticeable tremors in its legs, which alerted me to the possibility of MBD.
Behavioral Changes
1. Lethargy: A bearded dragon suffering from MBD may appear sluggish and less active than usual. This lethargy could be a sign of pain or discomfort due to the weakened bones.
2. Loss of appetite: As MBD progresses, bearded dragons may lose interest in food. This can result in weight loss and a decline in overall health.
3. Difficulty swallowing: If your bearded dragon is having trouble swallowing its food, it may be due to the weakened jaw muscles caused by MBD.
Diagnosing MBD in Bearded Dragons
By following these steps and staying vigilant in monitoring your bearded dragon’s health, you can play an essential role in the early diagnosis and management of MBD.
The Role of a Reptile Veterinarian
1. Finding a qualified reptile veterinarian: When it comes to diagnosing MBD, consulting an experienced reptile veterinarian is essential.
