CARE FOR GREEN IGUANAS AND OTHER REPTILES WITH SECONDARY
NUTRITIONAL HYPERPARATHYROIDISM (metabolic bone disease)
Susan
Horton, DVM

This
Green Iguana has SNHP and secondary abscesses because of it.
Initially I wrote this send home sheet for
Green Iguanas since they were the ones I most often saw with this
problem. Of course many more species are effected by this
disease. It is purely a disease of inadequate husbandry.
This disease syndrome affects any reptile but most especially
those reptiles with a very fast growth rate including but not
limited to: Sulcata tortoises, Leopard Tortoises, Bearded
Dragons, Leopard Geckos, Chameleons, frogs, Thai Water Dragons,
and of course Green Iguanas.
Your reptile has been diagnosed with a
metabolic condition that took many months to develop.
It is critically deficient in calcium and/or vitamin D 3.
Young reptiles have a tremendous need for calcium as they
grow. When calcium is
not available to them, they start to remove calcium from their own
bones. This
causes them to become soft and rubbery.
They fracture easily. Muscle
also needs calcium to function properly.
A calcium deficient reptile will tremor, have difficulty
eating, walking, defecating, and urinating.
Diet, as well as environment both have contributed to
creating this disease state.

This
little guy came to us covered in cage sand and with very soft
skeletal system.
The recovery
process may take months. Many pets recover completely.
Some are left with permanent deformities or nervous deficits.
Some will die. During the recovery process, your reptile
will need you to help feed it and nurse it back to health.
Some reptiles take weeks before they start to gain weight and eat
well on their own. Their recovery hinges on providing the
correct environment and nutrition. This handout will help
you through the critical stages of recovery.
MEDICATIONS:
Calcium supplementation:
Calciliquid- I will
prescribe this after your reptile has been examined.
Pick out a powdered commercial calcium supplement that is
phosphorus free. Use this on the days you are not using the
multivitamin supplement below.
Multivitamin
supplement:
A
powdered supplement should be added depended on your reptile's
current needs. We will decide this after the exam.
Other:
Decided at the exam.

Note this guy's shell deformity. His
shell was very soft.
FEEDING:
Hand feeding-choices
for syringe feeding
1. We use tube
feeding formulas developed by Lafeber's and others. The
metabolic Bone Disease hand feeding diet will probably be
appropriate. The amount will be decided at the exam.
2. Powder one part
rabbit pellets (run it dry through the blender) or use critical
care by oxbow and three parts pedialyte. Freeze in ice cube
tray and serve thawed with a syringe. This will work with
herbivores.
SOAKING:
Soak your reptile in warm water for 20 minutes once
to twice daily. The water should not be above its shoulders.
If it is very weak, you will need to monitor it the whole time or
hold up its head to make sure it does not drown.

More Shell deformities. He had severe
skeletal deformities as well.
ENVIRONMENT:

Secondary Nutritional Hyperparathyroidism (MBD)
can be prevented. It will lead to the death of the reptile
if proper measures are not taken. Don't let this happen to
your beloved reptile.
