She looks very healthy, big, and happy. It sounds a lot like the shed was bothering her, and she did have a few spots of retained shed or "stuck" shed that was probably bothering her, but no cause for concern at all.
Just as an FYI to you, since you obviously really care about your girl and much like I do, you'll drive yourself insane every time you think something is wrong, lol, so I thought I would just let you know what I just went through, or am still going through, lol, with my girl. I'm a few months a head of you, as my girl is 1 year and 2 months old, but she looks almost exactly like your girl, same length, same all-around shape with the big belly, same face, same head, same everything except Izzy is a bit more orange than your girl is, that's it. Otherwise they look exactly the same. I weighed Izzy yesterday before a
bath and she weighed 522 grams, then she pooped in the
bath so I weighed her again and she weighed 497 grams. And most of her weight is in her belly and her tail, her tail is really wide and heavy at the base. But the reason I'm telling you this is because Izzy started acting exactly the same way that your girl is now a few months ago, probably when she was around 11 months old. My first dragon was a male who lived to be just shy of 13, and he didn't go through this like Izzy is, and after reading your post I feel better, as I'm now thinking this may be a female hormonal thing...
I got Izzy at Petco when she was probably about a month old, just 4.5" long. She has eaten large BSFL as her main staple since I brought her home, with a hornworm or a wax worm as occasional treats. She's always been given a fresh salad every single day, but she never really touched it until a few months ago, while my 8 month old boy has eaten a large amount of salad since he was a month old. Izzy really wouldn't touch her greens/veggies unless I hand-fed them to her one piece at a time, like a piece of greens, then maybe a little piece of broccoli flower, a shed of carrot, but that's it. She loved her bugs though, and she has never once stopped eating them. She's never been sick, never had parasites or any other health issues at all. Then at around 11 months old she started to trash her enclosure, and I mean trash it! She started glass-surfing at the front doors of her enclosure all day long, I'd let her out (she's usually free in my bedroom a lot of the time anyway, I have a MegaRay basking spot set-up for her in there, and her enclosure is on the floor so she can come and go as she pleases, with the door to the bedroom latched). She would throw her salad all over the place, flip over basking logs and rocks, flip over her little kitten-bed she sleeps in, then jump in her large water dish and splash around all over the place. So that's when I started letting her run around my room, and run she did! She would hall-butt all over my bedroom, until she finally got tired and would fall asleep somewhere, but then she would just start over again.
Then she started slowing down on eating her bugs, which really worried me because she never had any issues with eating a ton of live BSFL and whatever else I offered her every day. But then i noticed one morning, while I was worrying about her refusing her bugs, that her entire salad was gone. I figured it was just tossed under all of the decor she had wrecked and thrown everywhere, but nope, it was gone, and she refused any bugs that day. So I made her a much larger salad the next day, left for a few hours, came home and the entire salad was gone again. I couldn't believe she had eaten that much salad, but since she was eating no live bugs it made sense. So essentially she just suddenly switched herself over from live bugs to a huge salad every day. i was afraid that she was going to lose weight, but at that time she only weighed in the low 400 grams, and since she started eating probably 85% salad and 15% bugs she has gained about 100 grams! She now hovers around 510 grams. And she's now all-belly, which I too thought might be infertile eggs when combined with all the glass-surfing and tank-trashing, but nope, no eggs. I'm looking at her right now as I'm typing and she's digging to get out right now...ugh.
She went to my CRV last month for her yearly wellness checkup, and this time I had a full blood panel done because I was worried about her weight gain and the big belly, I wanted to make sure there was no Fatty Liver Disease or Kidney issues...Oh, also, she hadn't had a shed in quite a while, probably not since she was 6-7 months old, and that wasn't a full body shed...well right at the beginning of January she started to shed her tail, then everything else followed, which made her even crazier. She just finished the shed, it took forever for her tail to shed this time, and since she finished the shed she has calmed down considerably, though she still does scratch to get out every day, and she still loves to over-turn her salad and throw it all over the enclosure before eating it, lol...
So her blood work was perfect, her fecal test was negative except for a few pinworm eggs that do not need to be treated, and her x-ray showed perfect bone density. So I asked my vet why she was flipping out every day, and why she suddenly decided to switch herself from almost all live bugs and no salad to almost all salad and no bugs in literally one day, and he summed it up to puberty and the shedding. Other than that she's perfectly healthy and happy, and even though everyone who sees her tells me she's fat and needs to lose weight because "she's going to develop Fatty Liver Disease if her belly stays that large", her blood work proves otherwise. She's just a big, healthy girl full of hormones who went through a long full-body shed that pissed her off, lol.
This is Izzy at 8 months old, before she put on the belly:
And was her around Christmas time in her new bed, bigger belly, but not full-Buddha yet:
During the shed, not happy at all, wondering why "I am" doing this to her, lol:
This is her yesterday, hiding the belly inside the bed...trust me, it's massive:
