Bearded Dragon Illnesses & Diseases To Watch Out For

It’s a good idea to recognize illnesses and diseases so your bearded dragon can live a long and healthy life.

When you have a bearded dragon as a pet it’s important to be able to look for warning signs that might indicate that they are not feeling so well. Bearded dragons don’t really show any emotions, unlike mammals. This has to do with how a reptile is and why they are such fascinating creatures. So, I would like to point out that bearded dragons do go through cycles each year. They might do this a couple times each year.

In this article I am going to be covering:

Bearded Dragon Brumation

Bearded Dragon Brumation

Ok, so I am sure you are aware of bears. Bears hibernate in the winter. They slow their metabolism way down, don’t move a lot, and pretty much sleep for several months. Well, a lot of people are actually shocked to learn that bearded dragons hibernate, as well. Instead of calling it hibernating we call it brumation with bearded dragons.

Bearded dragons will typically go through the brumation cycle once or sometimes twice a year. This is typically done in the winter or fall. This is how they adjust to the changing temperature, lighting, and lower amounts of food. I do want to point out that you should never stop a bearded dragon from trying to brumate. Let them do what is natural.

So, your bearded dragon will either completely sleep or kind of nap for most of the brumation period. Each bearded dragon is different and some bearded dragons will not brumate at all. There is really no rhyme or reason to it. It can last for a week or several months, too. Make sure you don’t wake them when they are brumating to give them a bath because this can actually make them end up brumating longer.

You need to understand that your bearded dragon should not lose weight when they go through the brumation cycle. They almost completely halt their metabolism and shouldn’t really lose any noticeable weight. If you notice that your bearded dragon is losing weight during brumation he/she probably has a parasite.

It’s also important that you keep your bearded dragon on the same lighting schedule. Don’t just completely turn off their lights when they are brumating. Also, make sure you still offer them food daily. You can cut it down to every 2-3 days if you want. Just monitor their food to see if they are eating anything at all.

Warning Signs of Abnormal Bearded Dragon Behavior

Warning SignsBelieve it or not, bearded dragons will show some symptoms if they are not feeling well. It makes take awhile for them to actually show their symptoms because of their genetic makeup. The reptilian mind is structured to never show any signs of weakness. They do this because if they show weakness other prey will go after them for food.

Below are some symptoms that your bearded dragon may show:


Every bearded dragon should have a regular bathroom schedule. If you notice that your bearded dragon eats daily but doesn’t poop once a day there could be an issue. The longer the bearded dragon goes without going poop the more you should be concerned.

Typically, if I notice that my bearded dragon hasn’t been going to the restroom I will give them a warm bath. Typically, you want the temperature of the bath to be 95 to 105 degrees for 15 or 20 minutes. You can gently rub their stomach when giving them a bath. Typically, your bearded dragon will go to the bathroom within 24 hours or most commonly while they are getting a bath. If your bearded dragon does not go after 24 to 48 hours after that you may want to contact a reptile veterinarian.


Your bearded dragon could get diarrhea from time to time. It could just be something as simple as they ate some bad food. Please make sure you see my article on bearded dragon diets. You could have fed them something you shouldn’t have fed them.

Also, they could have diarrhea because of stress. If you do notice that your bearded dragon is having diarrhea frequently then you might want to seek out medical help for them. You could contact your local veterinarian. Typically, diarrhea is an indication that your bearded dragon has a parasites or worms.


Your bearded dragon should be properly hydrated (see the bearded dragon caresheet for how you should hydrate them). Here are some indications that your bearded dragon is dehydrated:

  • Lack of energy.
  • Lack of appetite.
  • Wrinkled skin.
  • They perk up after drinking.
  • Sunken eyes.

One thing I have learned about humans is when we are dehydrated if you pinch our hand and our skin doesn’t go back quickly we are dehydrated. Our skins hold a lot of water and when it doesn’t go back it’s lacking water. The same can be done with your bearded dragon. You can gently pinch their skin and see if their skin goes back to its original spot quickly.

If they are dehydrated than you can get them some Pedialyte or a sports drink like Powerade. Do make sure you dilute the water at one part water and one part the sports drink.

You can use a spray bottle and they should drink it up. Otherwise, if you really feel they are severely dehydrated you can use an eye dropper or small syringe without a needle and give them water that way.

Droopy Eyes

Droopy eyes - bearded dragonIf you notice that your bearded dragon’s eyes look droopy. Meaning, they might look like a sad bearded dragon. It will look very strange when you look at them. But, the only way I can describe it is they will look like a bloodhound’s eyes. This can be an indication that they are having kidney issues.

It’s hard to say what droopy eyes can mean sometimes. It could be something as simple as an infection or they have a parasite, too. I would highly suggest that you take them to the veterinarian if you notice droopy eyes, though.

Swollen or Puffed Out Eyes

Their eyes can be inflated. This could just be shedding, but it can be a symptom that they are getting too much Vitamin A. This is called Hypervitaminosis A. Usually, swollen or puffy eyes are not caused from a parasite, though. Might want to monitor it for a couple days and if it doesn’t go away take them to the veterinarian.


Bearded dragons can suffer from paralysis. Most commonly, this is caused by feeding them food that is too large for them. As a general rule, you are not supposed to feed them anything bigger than the space between their eyes.

So, when they eat something too big it will put pressure on their spine. This extra pressure can cause them to suffer from paralysis. This can easily be treated, though. What you do is a get a washrag. Cut a hole in the washrag. Then, you put them on it so their stomach can hang. This takes the pressure off of their spine.

If this doesn’t help after a day or two I would recommend taking them to the veterinarian. They can do things which will reverse it quickly. I should note that if this goes untreated for a long period of time it could be fatal.

Bearded Dragon Diseases

Metabolic Bone Disease

Metabolic Bone DiseaseSadly, this is one of the biggest diseases that bearded dragons usually get. They can get this because their UVB lighting goes off without you knowing. Please see my article on bearded dragon lighting. But, MBD is caused by a lack of calcium and Vitamin D3. Also, it can be from Phosphorus which weakens their bones.

Here are some warning signs of MBD:

  • Jerky movements when walking.
  • A swollen bottom jaw.
  • Bumps on the back of the tail.
  • Ticks, spasms, twitches, or tremors.
  • Bumps on their legs.

Metabolic bone disease can be treated. But, once they get so bad off from it it’s a matter of time before they die. You might just end up watching them have trouble walking around their cage, scooting on their belly, etc. It’s really a painful disease to witness firsthand.

But, once you notice that they have MBD you can adjust their lighting or get them on a better diet. This will help the disease not to progress any further. I would recommend a supplement by Rep-Cal Reptile Calcium Powder with D3. You can sprinkle this on their food which will help give them the calcium and Vitamin D that they need to help MBD from progressing any further.

Hopefully, this article has helped with any questions you might have on bearded dragon illnesses. A lot of the above can be avoided by changing their habitat or changing their diet. Please leave any questions or comments you have down below.

  1. Very interesting! My daughter got one about 2 months ago. Ours is very young and so cute. They told her at the pet store to make sure that she dust their crickets with calcium powder. She does it every single time. You can’t overdo it with calcium powder, can you?

    1. Congratulations, on the baby bearded dragon. They are so cute when they are babies.

      The best way for them to get D3 is from the sunlight, and calcium is from the food they eat. For D3 you really can’t overdo it because in the wild they sit outside all day and they absorb it that way.

      As I have stated you can overdo it with Vitamin A, and it is possible to give them too much phosphorus to calcium ratio. It’s very hard to overdo it with calcium, though.

      So, it short I wouldn’t worry about overdoing it.

  2. My bearded dragon seems to be very dehydrated. I have been misting her with some Powerade (which is a 50 to 50 mix). I wasn’t aware that they could drink that. After two days I have seen a lot of improvement. I was thinking she was sick, but hopefully, she is getting better.

    1. Good to hear. Yeah, a lot of people are actually unaware that they can drink Powerade. They actually like it. Just keep feeding her. Also, throw in some cucumbers (cut up of course) because they do contain a lot of water.

      You can give her a bath for 20 minutes, too which should help with hydration.

  3. I thought my bearded dragon was dying because she was hiding for 3 weeks. It was really starting to stress me out. All she did was sleep. I wasn’t aware that bearded dragons actually brumate. I don’t like when he does it, but once he wakes up he is back to his same old energetic self!

    1. Yep, I remember the first time my bearded dragon brumated. I was wondering why she was sleeping so much. I actually tried to give her a bath, too. It did make her brumate longer.

  4. Just the other day I was watching YouTube and did see some bearded dragons that had MBD. It is really hard to watch.

    If their light does not go out can the bulb still not be producing UVB rays?

    1. I know what you’re saying. I was going to post a video of a bearded dragon with metabolic bone disorder, but I couldn’t pull myself to actually post the video. It is very hard to watch another reptile suffering.

      That is a great question. Yes, actually the light bulb might not be out, but the UVB rays can become less and less over time. Therefore, this is why I recommend that you change the bulb every six months regardless if the UVB light is out or not.

  5. Our beardy seems to get a lot of diarrhea when he was left with my friend when I went on holidays. I was really worried but after reading your post, I suspect it was the stress of not being at home.
    Thanks for sharing this informative post.

    1. My guess would be that your friend probably fed him something that didn’t have a lot of nutritional value. Please see my article on bearded dragon diets. Bearded dragons are not like human beings though. They don’t get stressed when we are not around. In fact, as much as we want to believe they wouldn’t be sad if we weren’t around. We could drop dead right in front of them and they wouldn’t be depressed or anything about it, though.

  6. Very helpful information on bearded dragons. My cousin has one and I think that this reptile is quite funny animals and very intelligent.  The way that they turn their heads to the side when they look at you.  I did get to hold his bearded dragon for the first time a couple days ago.  It was pretty neat!

     I plan to get one for my 8-year old son, he is very interested in them.  Do you think 8 years old is too young to have a bearded dragon, though?

  7. Hi! Thank you for this very helpful information! Yeah, as you have said bearded dragons don’t really show any emotions! And thus it’s a bit difficult to detect if they are getting sick! But I’ll be on the watch out having all these tips described here. Paying careful attention to there diet is something that others have also recommended and I have confirmed its importance reading your post.
