Vet Explains: Symptoms, Causes, and Treatments of GI Stasis in Rabbits

GI Stasis is one of the most prevalent conditions affecting rabbits. While it has the potential to be fatal, as a pet owner, you can take preventive measures to protect your bunnies. 

And it all starts with learning more about it so you are ready to take all that it needs to protect them.

Understanding GI Stasis in Rabbits

Rabbits typically eat a diet rich in hay and vegetables, and their gut is adapted to extract nutrition from these high-fibre foods efficiently.

Now, imagine this food-processing machine working round the clock. It needs to keep churning steadily, extracting nutrients, forming waste products, and expelling them. 

But what happens when this machine slows down or stops?

This condition is commonly known as gastrointestinal stasis, or GI stasis for short. In this state, the normal movement of the rabbit’s gut slows down significantly or comes to a halt. 

This slowdown can cause a variety of problems:

  • Food Build-up: When food doesn’t move through the gut as it should, it can start to pile up. This blockage can make the rabbit feel full and they stop eating. Rabbits denying food is one of the early red flags and should be taken seriously.
  • Gas Accumulation: The bacteria in the rabbit’s gut can begin to ferment the stagnant food which in turn produces gas.

    “The acute gas accumulation can cause dilation (the medical term for expansion) of the stomach and intestinal tract which can lead to severe shock and can quickly turn fatal”, says Dr Abhishek Shokeen, Veterinarian, BVSc & AH who specializes in exotic pet animals.
  • Harmful Bacteria Overgrowth: When the gut slows down, harmful bacteria start growing, releasing toxins.

Dr Shokeen further mentions that when these harmful bacteria continue to stay in the gastrointestinal tract due to decreased motility, these are absorbed systemically and cause systemic endotoxemia(when toxic substances enter the bloodstream) or sepsis(when the body’s immune response triggers widespread inflammation leading to tissue damage, organ failure, and death) which can be life-threatening!

  • Dehydration of the Gut Contents: When the contents of the gut remain stagnant for too long, they can become dry and hard, making them difficult to pass and potentially leading to blockages which in turn results in rabbits pooping very little or not at all.

    That’s why it’s important to always be checking on your bunny’s poop as it can be an indication of something not right

These problems collectively can make the rabbit feel quite sick, and if not treated promptly, GI stasis can be life-threatening. 

What Causes GI Stasis in Rabbits?

Determining what triggers GI Stasis can be crucial for rabbit owners. Below are the key factors that can lead to this condition:

  • Dietary Issues: The most common cause of GI stasis is an improper diet. Rabbits have a unique digestive system that requires a large amount of indigestible fibre, such as hay, to function correctly. This fibre aids in maintaining regular and healthy gut movements.

    Dr. Abhishek mentions that poor-quality long strands of hay, foods high in sugar content such as sweet fruits (which should always be given as treats), and fermentable foods can all contribute to GI Stasis in your bunny.

    “Sudden dietary changes can also contribute to it so ensure to introduce new food gradually”, says Dr. Abhishek.
  • Lack of Physical Activity: Exercise is essential for maintaining a healthy digestive system in rabbits. Physical activity stimulates gut movement and aids in digestion.

    When a rabbit doesn’t get enough exercise, their gut movement can slow down, increasing the risk of GI stasis.
  • Stress: Sudden changes in a rabbit’s environment, routine, or diet, can lead to stress and trigger a slowdown in gut movement.

    A few examples could be loud noises, the presence of predators (even just sensing or smelling them), improper handling, and even transport can be stressful to a rabbit.
  • Pain and Underlying Health Issues: Pain, especially chronic pain, can lead to a decrease in a rabbit’s appetite and activity level, both of which can slow down gut movement and lead to GI stasis. This pain can be due to various underlying health problems, such as dental disease, kidney disease, or bladder stones.

    Dental disease is particularly noteworthy as a rabbit’s continuously growing teeth can cause significant discomfort if not properly maintained, affecting the rabbit’s ability to eat fibrous foods.

    Older rabbits with osteoarthritis are also susceptible to it due to pain and lack of activity.

    Osteoarthritis in rabbits is basically when their joints gradually wear down over time. This can make moving around painful and difficult for them. It’s often due to old age, but can also happen from injuries or if the rabbit is overweight.
  • Dehydration: Rabbits need to stay well-hydrated for their digestive systems to function properly. Dehydration can make the contents of the gut dry and difficult to move, increasing the risk of GI stasis. 

Signs of GI Stasis in Rabbits

Identifying GI stasis in its early stages can be lifesaving for your pet rabbit. As a rabbit owner, being able to recognize the signs is crucial. Here are some symptoms in more detail:

  • Reduced Appetite or Anorexia: A rabbit’s appetite can say a lot about its health. One of the early signs of GI stasis is a reduced appetite or complete refusal to eat.

    This isn’t just limited to their regular food – a rabbit with GI stasis may even refuse their favourite treats. They might show interest in food, sniff it, but then turn away without eating. If you notice your bunny doing that, chances are that he is suffering from GI Stasis.
  • Rabbit Not Pooping: Any sudden changes in faecal pellets should be noted, as they can indicate a problem. Ideally, your bunny should produce small, round, and dry faecal pellets. These pellets should be plentiful because rabbits poop a lot!

    In GI stasis, the faecal output decreases noticeably. The droppings may become smaller or misshaped. They might be strung together with fur or mucus, or in severe cases, the rabbit may stop producing the poopy balls altogether.
  • Abdominal Distension or Hardness: Dr. Abhishek stresses the fact that abdominal dilation or the appearance of bloat should always be taken as an emergency. Gastric dilation can quickly turn fatal and you should quickly take the rabbit to the nearest vet when it is noted.
  • Behavioural Changes: GI stasis can cause considerable discomfort, which can lead to noticeable changes in your rabbit’s behaviour.

    Your usually energetic bunny might become lethargic or less active. They might hide in a corner, refuse to come out of their cage, or stop grooming themselves, resulting in a dishevelled appearance.

    In some cases, your rabbit might seem unusually aggressive or show signs of pain, like grinding their teeth or hunching over.
  • Changes in Urination: While less common, some rabbits with GI stasis may experience increased frequency of urination in small amounts, which in later stages can progress to a complete cessation of urine production.
  • Temperature change: The typical body temperature of rabbits ranges from 38.6 to 39.7 degrees Celsius (101.5 to 103.5 degrees Fahrenheit). When they experience Stasis, the temperature falls below 38.3 degrees Celsius (101 degrees Fahrenheit) and can indicate GI Stasis.

    You can take their temperature by using any digital thermometer by inserting the tip gently into the rectum of the rabbit.

It’s important to remember that these signs can also be symptoms of other health problems. If you notice any of these symptoms, it’s crucial to consult with a veterinarian as soon as possible. 

Rabbit GI Stasis Treatment

When it comes to treating gastrointestinal (GI) stasis in rabbits, the approach is two-fold. 

First and foremost, professional medical intervention by a veterinarian is paramount to treat the condition, alleviate the symptoms, and address the root cause of the GI stasis.

Secondly, there are steps a rabbit owner can take at home under the guidance of a veterinarian. These primarily involve comforting measures and support to your rabbit’s needs during this difficult time. 

Both aspects are vital for a rabbit’s recovery from this serious condition. Let’s explore these in further detail.

Veterinary Treatment of GI Stasis in Rabbits

When it comes to professional veterinary care, the focus is on addressing the cause of the stasis, managing pain, and rehydrating and reestablishing normal gut function.

  • Assessment and Diagnosis: Your vet will begin by conducting a thorough examination, which may include blood tests, X-rays, or an ultrasound, to determine the severity of the GI stasis and identify any underlying conditions.
  • Fluid Therapy: Dehydration is a common issue in rabbits with GI stasis. Your vet may administer fluids subcutaneously (under the skin) or intravenously (into a vein) to rehydrate your rabbit and help soften the contents of the gut.
  • Pain Management: Pain relief is crucial as GI stasis can be painful due to gas build-up and gut distension. Pain can also deter your rabbit from eating and moving, which are necessary for recovery. Your vet will administer safe analgesics to help manage this pain.
  • Motility Drugs: These are medications that stimulate the muscles in the gut to start contracting again, aiding the movement of food and gas through the system.
  • Nutritional Support: If your rabbit is not eating on its own, your vet may provide a specially designed, nutrient-rich, high-fibre supplement that can be syringe-fed to your rabbit.
  • Addressing Underlying Causes: If the GI stasis is a result of another medical issue, such as dental disease, your vet will also treat that condition to prevent future episodes of GI stasis.

In severe cases where a blockage has occurred, surgery may be necessary. However, this is typically considered a last resort when all other treatment options have been exhausted.

With timely and appropriate veterinary care, many rabbits can recover successfully. Remember, each rabbit is unique, and your vet will devise a treatment plan that best suits your rabbit’s needs.

How to Take Care of Rabbits at Home After GI Stasis Treatment

Home treatment for GI stasis should always be guided by your veterinarian and is typically a supportive measure of professional treatment. Here are some home remedies for GI stasis in rabbits:

  • Hydration: Hydration is key in treating GI stasis. A rabbit suffering from this condition can become dehydrated due to a lack of food and water intake. Always ensure your rabbit has access to fresh, clean water. You may need to provide water via a syringe if your pet isn’t drinking on their own.
  • Gentle Massage: A gentle belly massage can help stimulate the gut. Always be very gentle and careful, as your rabbit’s abdomen may be tender and bloated. If your rabbit shows signs of discomfort or pain, stop immediately.

    Simethicone, an over-the-counter medication, can also be administered with a veterinarian’s advice if you suspect bloat, says Dr Shokeen.
  • Encourage Movement: Regular, gentle exercise can stimulate the digestive system and help move things along. However, do not force them, especially when unwell. Instead, provide a spacious environment where they can hop and explore at their own pace.

Remember, these steps are not a substitute for veterinary care but something to do at home while you wait for your appointment. 

FAQs about GI Stasis in Rabbits

  1. How long can a rabbit live with GI stasis?
    If left untreated, rabbits’ health with GI stasis can deteriorate rapidly, and in severe cases, death can occur within 24-48 hours. 


However, with early detection and appropriate medical intervention, many rabbits can recover fully from GI stasis. It’s essential for you to be aware of the symptoms and to seek veterinary care immediately if GI stasis is suspected.

Regular monitoring, ensuring a proper diet, and maintaining a stress-free environment can help prevent the onset of this condition.

That being said, every rabbit and situation is unique, so it’s always essential to consult with a veterinarian regarding any concerns about a rabbit’s health.

  1. Is GI stasis in rabbits contagious?
    No, GI stasis is not contagious. It’s a condition that results from dietary, environmental, or health factors, not from infection or transmission from another rabbit.
  2. How long does it take for rabbits to recover from gi stasis
    With early detection and prompt treatment, some rabbits might show improvement within 24-48 hours. However, complete recovery, where the rabbit is back to eating and behaving as usual, might take several days to over a week.

    In some cases, especially if there are underlying health issues or if treatment is delayed, recovery can take even longer.
  3. What foods cause GI Stasis in rabbits?
    Foods high in carbohydrates and low in fibre, like bread, cereals, and sugary treats, can contribute to GI stasis in rabbits. Feeding inappropriate vegetables, like iceberg lettuce, or offering too many fruits can also disrupt their digestive balance.

    It’s crucial to provide a diet primarily consisting of high-fibre hay, complemented by suitable greens and limited pellets, to maintain a rabbit’s digestive health.
  4. What does rabbit poop look like after GI Stasis?
    After an episode of GI stasis, a rabbit’s poop may appear smaller, harder, and less frequent than usual. The faecal pellets might be misshapen, possibly strung together by hair (indicative of hairballs), or even have a more mucus-like appearance.

    Over time and with appropriate care, the rabbit’s faecal pellets should return to their typical size, shape, and frequency, which are round, consistent, and plentiful.
