There are few situations as worrying for rabbit owners as being told their pet may need major surgery. When the problem lies in the gastrointestinal (GI) tract, the stakes feel even higher. Owners are often devastated to hear that their rabbit might have a blockage that requires an operation. The most common questions I hear are: “Is it safe? What are the risks? And is it worth it?”

The rabbit digestive system is a fascinating yet delicate design. When it functions smoothly, it keeps a rabbit healthy and active. If there is ever a problem, though, a rabbit can deteriorate very quickly. The difference between a treatable case of gut stasis and a life-threatening obstruction can be incredibly difficult to spot.

This article explains why GI surgery may be needed in rabbits, what the procedure involves, the risks and challenges, and what recovery looks like. The aim is to give owners the knowledge and reassurance they need to have an open conversation with their vet and make the best decision for their beloved pet.

Understanding the rabbit digestive system

Rabbits are hindgut fermenters. Their entire digestive system relies on the constant intake and movement of high-fibre foods, especially hay. Their guts never actually “rest”. The rhythmic contractions of the intestine keep everything moving forward.

This unique system produces two types of droppings:

Hard pellets (the ones we see in the litter tray)

Soft caecotrophs, which rabbits re-ingest directly to absorb essential nutrients.

Any disruption in this finely tuned process can quickly turn into a medical emergency.

The term most owners are familiar with is gastrointestinal stasis (gut stasis). This occurs when the normal movement of food through the gut slows down or stops altogether. Stasis is usually caused by an underlying issue such as dental disease, pain, stress, dehydration, or a low-fibre diet. Thankfully, most cases respond well to medical treatment.

A true obstruction, however, is different. This occurs when something physically blocks food and gas from moving through. The result is rapid and dangerous distension of the stomach and intestines, which can lead to rupture, shock, and death if not treated quickly. Recognising the difference between stasis and obstruction can be challenging, but it is an important skill for vets to have.

How Do We Decide if Surgery Is Needed?

When a rabbit presents with reduced appetite, lethargy, and decreased amount of droppings, the first step is working out whether we are dealing with stasis or an obstruction. The decision is critical; operating unnecessarily carries risks, but delaying surgery in an obstructed rabbit can be fatal.

Clinical Examination

Your vet will assess hydration, temperature, and overall demeanour. Gentle abdominal palpation may reveal gas build-up or, in some cases, a suspiciously firm lump.

Diagnostic Imaging

X-rays are usually the first test carried out. In stasis, the stomach may contain a mix of food and gas. In obstruction, it is typically distended with fluid and shows a characteristic gas pattern.

Ultrasound gives further detail, helping us visualise gut wall changes or even the blockage itself.

Blood tests provide extra clues, assessing kidney function, electrolytes, and blood glucose. A very high blood glucose level can be a worrying sign. Rest assured, your vet will discuss all test results and what they mean for your rabbit in detail.

Medical Management First

If the evidence points towards stasis, your vet will treat medically with intravenous fluids, strong pain relief, prokinetics (drugs to stimulate gut movement), and intensive syringe-feeding with a specially formulated recovery diet. Most rabbits improve within 24–48 hours.

If imaging confirms a blockage, or if a rabbit is deteriorating despite aggressive medical care, surgery may become the most favourable option.

What Happens During Surgery?

Understandably, the thought of a rabbit undergoing abdominal surgery is daunting. Modern anaesthesia and surgical techniques, however, have greatly improved safety. The surgical procedure will usually include:

Step 1: Pre-Operative Stabilisation

Wherever possible, it is important to stabilise the rabbit. It may be necessary to spend some time giving IV fluids, oxygen, and strong pain relief to prepare them for the general anaesthetic.

Step 2: Anaesthesia

The old belief that “rabbits don’t survive anaesthetics” is thankfully outdated. With modern monitoring equipment and tried and tested drug protocols, anaesthesia is much safer. A vet nurse will continuously monitor heart rate, breathing, oxygen levels, and temperature throughout the procedure to flag up any changes. This ensures that quick action can be taken should any problems become apparent.

Step 3: Exploratory Laparotomy

This is the actual surgery. The vet makes an incision into the abdomen and carefully inspects the entire gastrointestinal tract. If a blockage is found, they may perform:

A gastrotomy (opening the stomach)

An enterotomy (opening the intestine)

The obstruction, often a compact ball of hair and food, or less commonly a foreign object like carpet fibre, is removed. The gut and abdomen are flushed and carefully closed with fine sutures.

What Are the Risks?

GI surgery in rabbits is considered to be a high-risk procedure. It is always important to be completely honest with owners about this to manage expectations appropriately.

The main risks include:

Anaesthetic sensitivity

Rabbits are far more sensitive to anaesthetic drugs than dogs or cats. Their relatively small body size, fast metabolism, and high oxygen demand make it harder to maintain stable anaesthesia. Even with modern protocols, the risk of complications is higher.

Stress-related complications

Rabbits are prey animals, and being handled, transported, and hospitalised can be highly stressful. Stress alone can slow gut motility, making recovery more complicated.

Hypothermia (low body temperature)

Rabbits lose body heat quickly during surgery, especially when their abdomen is opened. Even a small drop in temperature can slow down recovery and worsen gut function, so active warming is essential throughout the procedure.

Hypotension (low blood pressure)

Anaesthetic drugs can reduce blood pressure, which in turn reduces blood flow to the gut and other vital organs. In a rabbit already compromised by gastrointestinal disease, this can make healing more difficult.

Respiratory complications

Rabbits have a delicate airway, and intubation can be technically challenging. Anaesthetic gases may sometimes cause irregular breathing patterns or shallow ventilation, which must be carefully managed.

Haemorrhage (bleeding)

The rabbit’s intestinal tract is highly vascular. Even with careful surgical technique, there is always a risk of significant bleeding during a gastrointestinal procedure.

Adhesion formation

Following abdominal surgery, rabbits can develop adhesions (scar tissue that forms between loops of bowel). These may cause ongoing discomfort or, in rare cases, further blockages later on.

Postoperative ileus (gut stasis)

Perhaps the most significant risk after gastrointestinal surgery is ileus – the slowing or complete halt of gut movement. Pain, handling, and anaesthesia itself all contribute to this. Intensive postoperative care, including pain relief, fluid therapy, and nutritional support, is essential to reduce this risk.

Infection and wound breakdown

As with any abdominal surgery, there is a risk of peritonitis if intestinal contents leak, or if the wound becomes infected. This is a serious complication that can be life-threatening.

Mortality

Even with the best available veterinary care, some rabbits do not survive gastrointestinal surgery. This is often due to the severity of the underlying problem rather than the procedure itself, but it is important for owners to be aware of the possibility.

The good news is that survival rates have improved considerably over the last few decades. Whereas older studies reported mortality rates of over 30%, more recent figures suggest survival for gastric obstruction surgery can range from 70–85%, depending on the rabbit’s condition, the skill of the surgical team, and the quality of post-operative care.

Recovery after Gastrointestinal surgery

The recovery period following gastrointestinal surgery in rabbits is every bit as critical as the operation itself. Rabbits are incredibly fragile patients, and their digestive system does not tolerate disruption well. After surgery, they require intensive nursing and vigilant monitoring to encourage the gut to start moving again. The first 24–48 hours after surgery are particularly critical.

Pain management is absolutely vital – uncontrolled pain alone can be enough to cause gut stasis. Rabbits also need carefully planned fluid therapy to prevent dehydration, alongside nutritional support. Syringe feeding with recovery diets is often necessary until the rabbit feels well enough to eat voluntarily. Monitoring droppings is one of the most reliable ways to gauge progress. The return of normal faecal pellets is a strong sign that the digestive tract is functioning again.

Owners also play a huge role – gentle encouragement, lots of cuddles, access to favourite foods, and a calm, stress-free environment can make all the difference. With the right care, rabbits usually go on to make a full recovery and enjoy a normal, happy life after gastrointestinal surgery.

Is it worth it?

When a rabbit is diagnosed with a complete gastrointestinal obstruction, there really are only two options: surgery, or sadly, euthanasia. No amount of medical management will clear a true blockage, and leaving it untreated leads to rapid deterioration.

The decision to go ahead with surgery isn’t straightforward, and it will always be unique to each rabbit and their family. Things your vet will carefully consider with you include:

Your rabbit’s age and general health. Younger, otherwise healthy rabbits tend to cope better with anaesthesia and recovery, while older or more fragile rabbits may carry greater risks.

How certain the diagnosis is. Imaging and clinical signs give strong clues, but your vet will talk you through how confident they are that surgery is the right step.

The financial aspect. GI surgery in rabbits is complex, and there can be significant costs involved, including the surgery, hospitalisation, and aftercare.

Your ability to provide nursing at home. Rabbits need intensive care in the days following surgery—timely medications, assisted feeding, close monitoring and a quiet, stress-free environment all make a huge difference.

When everything comes together and the operation is a success, the outcome can be extraordinary. Seeing a rabbit who was gravely ill just days before bouncing around, munching hay, and nudging for nose rubs again is one of the most rewarding experiences for vets and owners alike. For those that do recover, the long-term prognosis is generally very positive, with most rabbits returning to an excellent quality of life.

Conclusion

Gastrointestinal surgery in rabbits is widely recognised as one of the more challenging procedures to carry out in our furry friends. It carries genuine risk—but in the right circumstances, it can also be life-saving. Thanks to advances in anaesthesia, imaging, surgical technique and post-operative care, many rabbits now have a far better chance of pulling through than ever before.

If you ever find yourself in this difficult position, it’s important to have an open and honest discussion with your vet. Ask about the risks, the potential outcomes, and what kind of aftercare your rabbit will need at home. The decision is never easy, but when faced with a genuine obstruction, surgery is the only option that offers hope. For many rabbits and their families, taking that chance results in many more years of happy, healthy life together—and that is worth everything.
