Impaction in Bearded Dragons: Causes, Signs & Treatment

Bearded dragons are among the most popular pet reptiles in the UK, prized for their impressive appearance and hardy nature, making them suitable even for well-informed first-time reptile keepers. Despite their forgiving temperament, proper care is essential to prevent common health issues like impaction.

Impaction in bearded dragons is a serious digestive condition where indigestible material blocks the digestive tract, preventing waste from passing normally. If untreated, it can lead to severe health issues including paralysis of the limbs and even death.

What is impaction?

Impaction occurs when substances such as loose substrates, oversized or hard-to-digest food items accumulate and harden inside a bearded dragon’s digestive system. This blockage stops food and waste material from moving through naturally.

Unlike constipation, which is the build-up of faecal matter alone, impaction involves indigestible materials such as sand, walnut shells, or large insects with hard exoskeletons that the dragon cannot digest or pass.

Common causes of impaction in bearded dragons

One of the primary causes is ingestion of loose or unsuitable substrates from the tank floor. Common culprits include all types of sand—often surprising novice keepers—walnut shells, soil, wood shavings, and bark chips. These materials can be mistaken for food and lead to blockage.

Feeding food items that are too large or have tough outer shells, like superworms or large crickets, also raises risk. A helpful rule is never to feed anything larger than the distance between your dragon’s eyes.

Other factors include inadequate heating or UVB lighting, which slows digestion, dehydration, poor diet lacking proper nutrition, and overfeeding which can cause digestive slowdown and obesity.

How to recognise impaction symptoms

Dragons impacted by blockage typically show signs such as refusal to eat, lethargy, weight loss, and reluctance to move. They may be unable to pass faeces, noticeable by an absence of droppings for several days.

Severe cases can cause partial paralysis beginning in the hind limbs, progressing to the front limbs, trembling legs, and discomfort or swelling in the stomach area. Occasionally, affected areas between spines may bulge visibly.

Preventing impaction in your bearded dragon

Prevention is key. Use solid substrates like reptile carpet, stone or slate tiling, or newspaper that won’t be ingested. Always avoid any loose or particulate substrates.

Feed appropriately sized food smaller than the space between the eyes. Avoid overfeeding and limit hard-shelled insects like mealworms. Ensure your dragon’s enclosure has suitable heating and lighting with correct UVB exposure to aid digestion. Keep your pet hydrated with fresh water accessible and use regular misting or baths to encourage fluid intake.

What to do if your bearded dragon is impacted

Impaction rarely resolves without intervention. If you suspect your dragon is affected, begin by offering a reptile-safe natural laxative such as unsweetened pureed prunes applied with a syringe to encourage licking. Follow this with a warm bath up to the shoulders for up to 30 minutes, maintaining a consistent water temperature while gently stroking the abdomen from chest downwards to stimulate digestion. Avoid applying pressure or massaging roughly.

If no improvement occurs quickly or symptoms worsen, such as signs of paralysis or severe distress, seek veterinary care immediately. Improper attempts to force expulsion or excessive straining can cause rectal prolapse, an emergency with serious consequences.

Summary and responsible care tips

Impaction in bearded dragons is a serious but largely preventable condition. Through attentive husbandry—choosing safe substrates, feeding suitable food sizes, maintaining proper temperature and lighting, and ensuring hydration—you can greatly reduce your dragon's risk.

Regularly observe your dragon’s behaviour and faecal output to catch health issues early. Prompt action and expert veterinary support are crucial if impaction is suspected.

Caring responsibly for your bearded dragon promotes a happy, thriving pet and helps avoid stressful medical emergencies.
