She needs to see a vet. A bunny savvy vet. They’ll be able to give her the right medication and monitor her appropriately.

What’s her diet like? Sometimes stomach issues can be diet related.

It could be diet portions. Hay is essential for keeping the gut biome in check in order to maintain the bacteria needed to break down the variety of food digested. Has her hay consumption been lower than usual?

Some bunnies are prone to gas, so it would be good to have a go-to treatment plan. Also, sometimes new illnesses can present as familiar symptoms, so it’s important not to get too complacent.

I think whenever you suspect gas, give her a tummy rub and simethicone right away (it can’t hurt, even if it’s not needed), but if you don’t see an improvement within a few hours, you should head off to the vet. You can also push hay and fluids on her to try to get even more into her at those times when she seems a bit off. Stasis itself also causes gas, so it can end up being a chicken and egg type question. If stasis is causing the gas, often motility medication and pain meds are prescribed, as getting a gut in full stasis mode can be hard.

The main danger of gas is from the pain it causes, and pain can cause a rabbit to go into stasis. If the pain is severe, it can cause rapid fluctuations in body temperature that can send the rabbit into shock. So even if it is “just” gas, if it doesn’t resolve on it’s own within a few hours, the vet can prescribe pain medication to help the bun work through it on their own, if there isn’t an underlying cause.

I’ve never heard of vitamin drops as a treatment for gas, so I’m not sure I 100% trust your vet. You might ask them their feelings about pain management in rabbits and see what they say.

The rabbit gut functions best on lots of fiber and moisture. Slowdowns can cause gas, as can other shifts in the gut flora. You might try to (slowly) introduce some higher fiber veggies, like dandelion. The herbs mint and fennel are also thought to help with gas, so they might be good to introduce as a regular part of her diet.

Haha, it’s honestly really good that you are so attentive and observant!

Sometimes it’s really the smallest things that indicate a problem brewing, but it’s good you know she’s just a bit picky about pellets. It might be good to have some foods that she will ALWAYS eat, as a test to see how she’s doing. Cilantro is my go-to for my buns.

Sometimes the diet can cause gas to be chronic in buns. So you can try to slowly change the diet, remove and add things and see if that helps. Her tummy and gi might just be super sensitive. I know my buns will get gas every now and then and I just give them some gas drops and they are all good. Some of the food they eat can have the bacteria in their gut make too much methane and gas products which can cause the tummy to be uncomfortable until it gets out

As Bunny House suggested, you can try removing different parts of the diet (not hay though of course) and see if that helps. I know some buns just can’t have pellets, other’s can’t handle greens at all, or can only handle certain ones. As I mentioned, some veggies (like fennel and mint) are thought to help with gas, so you might try incorporating those into her diet (slowly of course).

Wick asked about this earlier, but how much pellet food does she get each day? Maybe she’s wolfing all her pellets down at once and that’s upsetting things?

As far as I know there isn’t a medicine… but the vet can maybe prescribe pain meds. I think if it seems to be increasing in frequency you should have your vet examine her. They can do an x-ray to see where the gas is building up, which might help identify the cause.

There is a feedback between pain (of any sort), GI slowdown, and gas. Any one thing can lead to the other, which can make the original cause worse. Even something like dental pain can cause GI slowdown, and then gas. So yeah… I think a thorough exam to rule out any other factors is a good idea.

That sounds like a good plan, hope you get some answers, or at least a plan of attack to find some answers!
