Cecal Torsion in Rabbits: Twisted Cecum and Acute Abdomen

Cecal torsion means the rabbit's cecum twists on itself. The cecum is a large fermentation pouch that helps rabbits digest fiber. When it twists, gas and intestinal contents can become trapped, and the blood supply to that section of bowel may be reduced or completely cut off. This can turn into a true acute abdomen very quickly.

For pet parents, the hard part is that the early signs can look a lot like severe gastrointestinal stasis: not eating, fewer droppings, belly pain, and lethargy. The difference is that torsion is an obstructive emergency. Supportive care alone may not be enough, and delay can allow the cecum to become damaged, necrotic, or even rupture.

Published rabbit case reports describe cecal torsion as uncommon but serious. In one reported domestic rabbit case, serial radiographs showed persistent gas in the cecum with abnormal left-sided, cranial displacement, helping support the diagnosis before surgery. Because rabbits often hide illness, a rabbit with sudden abdominal pain and no appetite should be treated as an emergency until your vet proves otherwise.

In many rabbits, the exact trigger is not clear. Cecal torsion is thought to happen when the cecum becomes abnormally mobile and then rotates, trapping gas and contents inside. As pressure builds, circulation can be impaired. In practical terms, this means the problem may start with gas and altered motility, then progress into a true twist.

Rabbits with underlying gastrointestinal slowdown may be at higher risk for severe cecal gas buildup, and that can make the abdomen more unstable. General rabbit GI disease is often linked to low-fiber intake, excess carbohydrates, pain, stress, dehydration, dental disease, overheating, or another illness that causes a rabbit to stop eating. Those factors are well documented for GI stasis, and they may overlap with cases that later prove to be obstructive disease rather than simple hypomotility.

It is also important to remember that not every painful rabbit with a gas-filled abdomen has cecal torsion. Your vet may need to sort through other emergencies such as intestinal obstruction, liver lobe torsion, severe GI stasis, peritonitis, or reproductive disease. That is one reason imaging matters so much in rabbits with acute abdominal pain.

Diagnosis starts with stabilization and a careful exam. Your vet will ask when your rabbit last ate, drank, urinated, and passed stool, then check hydration, temperature, heart rate, pain level, and abdominal size. Rabbits with acute abdominal disease can decline quickly, so your vet may begin warming, fluids, oxygen support, and pain control while diagnostics are underway.

Abdominal radiographs are usually the first key test. In rabbits with GI stasis, X-rays may show a gas-filled stomach and cecum. With cecal torsion, your vet is looking for a markedly distended cecum in an abnormal position, persistent gas, and signs that suggest obstruction rather than uncomplicated stasis. Ultrasound can sometimes add information about bowel position, wall health, and free abdominal fluid.

Bloodwork helps assess dehydration, electrolyte changes, organ function, and whether shock or tissue injury may be developing. In some rabbits, the diagnosis is still only strongly suspected until exploratory surgery confirms the twist. That can feel frustrating, but it reflects how similar rabbit abdominal emergencies can look in the early stages.

Because the exact cause is not always known, there is no guaranteed way to prevent cecal torsion. Still, good rabbit digestive care may lower the risk of severe GI problems that can overlap with or complicate abdominal emergencies. The foundation is a high-fiber, hay-based diet, measured pellets, fresh water, regular exercise, and prompt treatment of dental pain or other illnesses that reduce appetite.

Try to act early when your rabbit seems "off." Rabbits often hide pain, so a rabbit that eats less, produces fewer droppings, or sits hunched should not be watched for a day or two at home. Early veterinary assessment may catch GI stasis, dehydration, dental disease, or another painful condition before the abdomen becomes critically distended.

Prevention also means planning ahead. Know where your rabbit-savvy daytime clinic and after-hours emergency hospital are located before a crisis happens. If your rabbit has a history of recurrent GI episodes, ask your vet what monitoring steps are most useful at home and when they want to see your rabbit urgently.
