Common Bearded Dragon Illnesses
Updated August 1, 2026
💩 Impaction
Impaction is when the digestive tract gets blocked, preventing the dragon from passing poop. It's one of the most common and dangerous issues in captive bearded dragons.
⚠️ Signs
- • No bowel movements for 1+ weeks
- • Swollen belly, hard to the touch
- • Straining to poop
- • Loss of appetite
- • Lethargy
🛠️ What to do
- • Warm bath (10-15 min) + gentle belly massage
- • Ensure proper temps (basking 100-110°F)
- • Offer hydration (cucumber, baths)
- • If not resolved in 3-5 days: see a vet
Prevention: proper temps, proper UVB, good hydration, avoid loose substrate (sand).
🐛 Parasites
Internal parasites (coccidia, pinworms, roundworms) are common, especially in young dragons and wild-caught specimens.
⚠️ Signs
- • Diarrhea or smelly poop
- • Weight loss despite eating
- • Loss of appetite
- • Dehydration
- • Smelling bad in general
Diagnosis requires a reptile vet to do a fecal exam. Treatment is deworming medication. Keep the enclosure ultra-clean during treatment.
🫁 Respiratory Infection
Caused by bacteria, usually from incorrect temps/humidity or a dirty enclosure.
⚠️ Signs
- • Wheezing, clicking, or mucus sounds
- • Gasping or open-mouth breathing
- • Bubbles from nose/mouth
- • Lethargy
- • Not eating
This requires a reptile vet for antibiotics. Raise temps to 100-110°F while arranging the appointment.
🍄 Yellow Fungus (Yellow Blight)
A serious fungal infection that attacks the skin and can become systemic.
⚠️ Signs
- • Yellow, crusty patches on skin
- • Discolored scales
- • Wounds that won't heal
- • Spreads over time
This is serious and requires a reptile vet. Early treatment has better outcomes. Keep the dragon clean and dry while waiting for the appointment.
👁️ Eye Problems
Eye issues can be from injury, infection, or vitamin A deficiency.
- Swollen/closed eye: could be injury, infection, or stuck shed. Warm compress helps.
- Cloudy eye: could be infection or vitamin A deficiency — see a vet.
- Discharge: sign of infection — see a vet.
- Sunken eyes: usually dehydration — offer baths and hydration.
👨⚕️ When to see a reptile vet
🚨 See a vet immediately if:
- • Not eating for more than 2 weeks
- • Visible weight loss
- • Labored breathing
- • Diarrhea lasting more than 2 days
- • Swollen body parts
- • Seizures or twitching
- • Any sign of yellow fungus
