By now, you should know that green onions are among the poisonous foods you need to avoid as far as bearded dragons are concerned.  To find out more about the risks, read on.

Disproportionate Ca:P

The proportion of calcium to phosphorus in onions is unbalanced.

Phosphorus has a high calcium-binding ability.  It is not suitable for your bearded dragon due to the ion imbalance caused in the body.  

The proper calcium to phosphorus ratio for beardies is 1:1 or 2:1.  A high phosphorus ratio will bind with calcium and inhibit calcium absorption in your pet lizard’s body.  

When the calcium levels in your bearded dragon’s bloodstream are too low, they start extracting calcium from its bones. emoving calcium from the bones can eventually lead to calcium deficiency, causing Metabolic bone Disease (MBD).

The disease causes severe bone, muscle, and tissue damage, resulting in paralysis or death.   Alert your vet immediately if you notice any signs of metabolic bone disease in your bearded dragon. These include: 

  • Lack of appetite
  • Lethargy and weakness
  • Stress
  • Constipation
  • Receded lower jaw
  • Swollen limbs and jaw
  • Bumps along the spine or bones
  • Soft jaw, and facial bones
  • Bowed limbs and arched spine
  • Fractures and broken bones
  • Greenstick fractures (folded or bent bones)
  • Trembling and twitching limbs
  • Tremors and seizures
  • Paralysis or difficulty moving

Unfortunately MBD is one of the most common diseases among domestic bearded dragons. Still, it is easily preventable with proper diet and care.

Toxification Of The Digestive System

Bearded dragons has delicate digestive systems that can cause problems when ingesting the toxic substances in green onions.  If your beardie eats green onions, it can lead to vomiting, burning sensation, and incomplete digestion.

High Acidic Level

The high acidic level in green onions may cause a burning sensation on the tongue and throat of the bearded dragon.  When bearded dragons eat green onions, they will become irritated and stop eating.

Green Onions can also cause heartburn and irritation in the throat.  The high acid content interferes with the normal function of the digestive enzymes in the stomach by de-activating them.

Eventually, there will be poor digestion and absorption of nutrients in your bearded dragon’s body.
