It’s normal for a bunny’s hind quarter to arch up like that in many breeds.  Here, I googled a chart.

Your bunny seems to have the commercial body type.

It’s also perfectly normal for a rabbit to not want its belly rubbed.  Flopping over sideways is something rabbits do when they are very relaxed and comfortable.

Are there other symptoms?  Is your rabbit still eating and pooping?

Has the vet palpated her abdomen? For lumps and stuff?

I hope the stasis-treatment helps. Has she been through any particular illnesses in her life?

It is normal for a bunny to not want her tummy touched by a human, but if they have tummy trouble, they will often let you, if you sit the bun in your knee.

{{{Fluffy!}}}
She can probably have more then usual but not whole apples. That seems too much.

Is she on pain meds at the moment?

Was the X-ray just of her abdomen?

I wonder if worthwhile to X-ray her hind end to look for any changes on her spine. Or ultrasound of bladder & abdomen in case she developed surgical adhesions. (Did her bouts of stasis and incontinence increase soon after her spay?). She didn’t have a typical spay either, is that right? I’m trying to remember if it was more complicated because of the problems she had with her uterus.
Cystitis is another consideration and is painful, so could cause a rabbit to not want to eat.

If you have access to pesticide-free apples you can give her more peel than apple flesh, the peel has less sugar and more fiber and lots of antioxidants.

It may seem wasteful to just use the peel, but you can make apple-pie for yourself with the left-over apple flesh =)

Jersey has some great suggestions.

Adhesions don’t go away with time. They are basically mistakes in the healing process. They form when wounds heal against each other and create connective tissue that locks the wounds together. It is basically the same process that allows the edges of a deep cut to fuse together even if there is a piece of skin missing from in between the edges. Normally it is a good thing that the body can fuse itself back together, and is only a problem when parts that should not be connected are both wounded and held together during healing.

Eepster is right. If adhesions occurred, then they will not just go away.

Poor Fluffy. I know you have been through so much with her.

I’m so very sorry to hear your bun is unwell and want to offer ((((Healing Vibes))) to Fluffy and (((Hugs)))

The tissue actually becomes fused together with scar tissue. Like Eepster said, organs can become fused together or fused to the abdominal cavity wall. Depending on what is fused together, where, and how then, yes, it can cause gi stasis.

This is from vetstream:

Introduction

Rabbits are well known for their propensity to form adhesions after surgery in the coelomic cavity.
They are widely used as animal models for research on intra-abdominal adhesions.
Cause : inflammation of tissues within abdominal cavity.
Signs : abdominal discomfort, lethargy, reduced appetite/anorexia, reduced fecal output/diarrhea.
Diagnosis : clinical assessment, radiography, ultrasound, abdominal fluid, surgery or endoscopy.
Treatment : surgical resection.
Prognosis : depends on the location of the adhesions.

Presenting signs

May be acute or chronic in onset.
Reduced appetite.
Lethargy.
Reduced fecal output (gastrointestinal stasis).
Chronic diarrhea.
Abdominal discomfort.
Bruxism.

Acute presentation

Anorexia.
Gastrointestinal stasis with cessation of fecal output.
Abdominal distension.
Abdominal pain.
Bruxism.

if they performed the surgery wrong in the first place you could take her to see a specialised.

sometimes normal vets get it wrong. I’ve found that the hard way.

rabbits do shake and fall to the side a little when they are asleep

my rabbit runs back and forth when happy.

I suppose you will know your bun and know when something is wrong.
I know how they sit uncomfortably and did you say she didn’t always set like that.
I think with your bun having gi stasis that she will sit uncomfortably.

pain killers should help.

I would ask if there is a necessity to hospitalised because more stress won’t be good for bun.
is there something they can do that you can’t do when she’s at home?

I’m so glad she’s doing better! Continued healing-vibes for her!

So happy to hear this!!!! Thanks for the update its very kind of you

I’m glad to hear Fluffy is feeling better. Hoping for more good days than bad from now on.
