MBD Warning Signs

Metabolic bone disease (MBD) is the most common preventable husbandry failure in captive geckos. It is what happens when the calcium leaving the body exceeds the calcium coming in, because supplementation is inadequate or because the vitamin D3 needed to absorb dietary calcium is missing. The body pulls calcium from the skeleton. The skeleton softens and deforms.

MBD is reversible early and irreversible late. The window matters. The MBD Warning Signs playbook is the document the keeper reads before symptoms appear, so they catch the soft-jaw stage instead of the rubber-leg stage.

What the document does:

It splits MBD signs into the early reversible window (soft jaw, tremors, slight limb curvature, decreased grip in cresties, slowed growth) and the late permanent damage window (severe rubber limbs, kinked spine, fractures, hunched posture). It walks the husbandry audit the vet will ask about (calcium and D3 schedule, UVB lighting, diet quality). It directs immediate action when signs appear and explains what the vet will likely do.

What is included:

• Early signs section listing six reversible warning signals
• Late signs section listing seven permanent damage indicators
• Husbandry audit broken into calcium and D3 (with species-specific schedules), UVB lighting (T5 HO 5.0 product recommendations and replacement cadence), and diet quality (prey sizing, gut-loading, CGD brands)
• Supplement age and consistency checks (powder over 6 months past opening loses potency)
• UVB obstruction reference (glass blocks all UVB, mesh blocks 30 to 50 percent)
• Immediate action when signs appear (book the vet today, minimize handling, optional vet-directed liquid calcium)
• What the vet will likely do (calcium gluconate injections plus husbandry correction)
• Prevention routine

Format and how it works:

Word version (.docx) for editing and a PDF version for printing. The playbook is written to be read before MBD appears as a prevention reference, and re-read during diagnosis as an audit framework. Most keepers print and clip into the kit binder.

Why this version is different:

Most MBD references describe late-stage symptoms only, by which point reversal is impossible. The MBD Warning Signs playbook splits early reversible signs from late permanent damage, which is what makes the early-vet visit timing actionable. The supplement-age and UVB-obstruction sections also catch the two most common husbandry failures that drive MBD even in keepers who think they have it covered.

Who this is for:

For gecko keepers in the first year of ownership who want to prevent MBD rather than diagnose it after the fact, and for breeders who want every buyer to audit their supplement routine on day one. Pairs with the Feeding Log (which tracks supplementation), the Daily Husbandry Log, and the Vet Now Checklist.
