Pathophysiology

MBD results from disruption of calcium homeostasis. When dietary calcium is insufficient, parathyroid hormone (PTH) mobilizes calcium from bone to maintain blood levels — progressive demineralization weakens the skeleton. In UVB-dependent species, insufficient UVB exposure prevents cutaneous Vitamin D3 synthesis, blocking intestinal calcium absorption. Secondary nutritional hyperparathyroidism is the most common form.

Clinical Signs

Soft, rubbery jaw (mandibular swelling)
Pathological fractures from minimal trauma
Muscle tremors, twitching (hypocalcemic tetany)
Inability to lift body off ground (weakness)
Spinal kinking and limb deformities in juveniles
Anorexia, lethargy, failure to thrive

Prevention Protocol

Dust all feeder insects with calcium powder (without D3 for daily use, with D3 2-3×/week). Provide UVB lighting appropriate for species (T5 HO 10.0 for desert species, 5.0 for tropical). Replace UVB bulbs every 6 months — UVB output degrades significantly before visible light fails. Gut-load feeder insects with calcium-rich vegetables 24 hours before feeding.
