Changes

When juveniles have been affected during growth, they may have poorly mineralized and pliable mandibles which is a sign of prolonged MBD. This results in distorted jaw bones and a characteristic facial 'smile'. In chameleon species, MBD causes difficulty protruding or retracting the tongue.

Tremors, muscular fasciculations, paresis and seizures usually develop in more severe cases of MBD with developed hypocacaemia. However in most cases, calcium and phosphate levels usually appear normal.

In some cases, hindlimbs may appear very muscular as a result of thickening of the bone cortex caused by marked fibrous osteodystrophy in the long bones. Palpations and radiography suffice to differenciate from healthy tissue.
