Metabolic Bone Disease

What is it?
Metabolic bone disease (MBD) develops when a sugar glider's diet has too little calcium, too much phosphorus, or not enough vitamin D. The body pulls calcium from the bones, leaving them weak and prone to fracture. It is usually caused by fruit- or insect-heavy diets without proper supplementation.
What signs should I watch for?
Signs to watch for include weakness or trouble climbing and gliding, hind-leg weakness or paralysis, tremors or seizures, swollen or bowed limbs, and fractures from minor falls.
How is it diagnosed and treated?
Diagnosis is based on diet history, exam, X-rays, and blood tests. Treatment includes calcium supplementation, correcting the diet, cage rest, and supportive care.
Can it be prevented, and what's the outlook?
- Feeding a balanced, veterinarian-recommended diet prevents MBD.
- Many gliders improve with early treatment.
