GI Stasis in Rabbits: This Is an Emergency
GI stasis — gastrointestinal stasis — is one of the most serious and most common emergencies that rabbit owners will ever face. When a rabbit's gut slows or stops moving entirely, gas and ingesta build up rapidly inside the digestive tract. Painful bloating follows. Toxic bacteria proliferate. Without prompt veterinary treatment, a rabbit can deteriorate and die within 24 to 48 hours.
There is no waiting and seeing with GI stasis. If you suspect your rabbit is in stasis, call your vet immediately.
What Exactly Is GI Stasis
A healthy rabbit's gastrointestinal tract moves constantly. Food passes through at a rapid rate, and a rabbit should produce hundreds of small faecal pellets throughout the day and night. The gut is essentially never switched off.
In GI stasis, peristalsis — the muscular contractions that move food through the gut — slows dramatically or stops altogether. Gas produced by gut bacteria accumulates and cannot escape. The rabbit's abdomen becomes distended and intensely painful. As the condition worsens, the rabbit stops eating entirely, which further slows gut motility, creating a dangerous downward spiral.
GI stasis can be primary, where the gut slows for no identifiable cause, or secondary, where it is triggered by an underlying problem. Secondary stasis is more common and potentially more serious because the underlying cause must also be treated.
What Causes GI Stasis
Understanding the causes of GI stasis helps owners both recognise when it may be occurring and take steps to prevent it. Common causes include:
- Insufficient dietary fibre — a diet low in hay is the single most common underlying factor
- Dental disease — tooth pain reduces appetite and changes eating habits, leading to reduced gut motility
- Stress — changes in environment, the presence of a predator, loud noises, or the loss of a bonded companion can all trigger stasis
- Dehydration — reduces gut fluid balance and slows movement
- Pain from any source, including urinary problems, musculoskeletal injury, or post-operative discomfort
- Hairballs or ingested foreign material causing partial or complete gut obstruction
Note that true obstructions — where a blockage physically prevents passage — are a distinct and even more urgent surgical emergency within the broader category of gut problems in rabbits.
Recognise the Signs — Any of These Requires Immediate Veterinary Attention
The following signs indicate a rabbit may be in or entering GI stasis. Do not wait for all of them to appear before seeking help. Even one of these signs in a rabbit that appears unwell is enough reason to call your vet immediately.
- No faecal droppings for 6 to 12 hours, or a dramatic reduction in the number or size of droppings
- Not eating — particularly alarming in a species that normally grazes continuously
- Hunched posture with the abdomen tucked up
- Teeth grinding (bruxism), which indicates pain
- A visibly or palpably bloated, hard, or tense abdomen
- Lethargy — sitting hunched in a corner, reluctant to move
- Pressing the belly to the ground in an attempt to relieve discomfort
Call your vet immediately if you observe any of these signs. Do not delay. Time is critical in GI stasis.
What to Do Right Now
While you are arranging emergency veterinary care, here is what you can do at home:
- Call your vet or an out-of-hours emergency veterinary service without delay. Note the time your rabbit last produced droppings and tell the vet when you call.
- Keep your rabbit warm but not overheated. A rabbit in pain and shock may lose body heat quickly — a warm, quiet environment reduces additional stress.
- Offer fresh hay and fresh water. Do not force your rabbit to eat or drink. Simply making these available is appropriate.
- Note any recent changes in diet, environment, or behaviour that may help your vet identify an underlying cause.
- Transport your rabbit to the vet in a secure, padded carrier. Minimise vibration and keep the journey as stress-free as possible.
These steps support your rabbit while you seek help — they do not replace veterinary treatment. Call your vet immediately and get your rabbit seen as soon as possible.
What NOT to Do
In the panic of seeing a sick rabbit, owners sometimes reach for home remedies or wait in the hope the rabbit will improve on its own. Both approaches can be fatal. Specifically:
- Do not give simethicone (GasX) or any other over-the-counter remedy without explicit instruction from your vet. While simethicone is sometimes recommended by vets in specific situations, giving it without assessment may mask symptoms and delay appropriate treatment.
- Do not give any pain relief that has not been prescribed for your rabbit. Human pain medications including paracetamol, ibuprofen, and aspirin are toxic to rabbits.
- Do not wait and see. GI stasis progresses rapidly. A rabbit that appears only mildly unwell can deteriorate to a critical state within a few hours.
- Do not attempt to massage the abdomen vigorously or force your rabbit to exercise — these actions can cause harm if there is an obstruction.
- Do not syringe-feed critical care food or any other supplement at home unless your vet has specifically advised you to do so. Force-feeding a rabbit with a true obstruction can be dangerous.
If in doubt, call your vet immediately. This is always the right course of action.
How Vets Treat GI Stasis
Once at the clinic, your vet will assess your rabbit's abdomen, listen for gut sounds, and may take radiographs (X-rays) to determine whether gas is present and whether any obstruction is visible. Treatment is typically intensive and may include several components:
- Gut motility drugs — medications such as metoclopramide, ranitidine, or cisapride stimulate the gut to start moving again
- Pain relief — effective analgesia is critical, as pain itself further suppresses gut motility
- Intravenous or subcutaneous fluids — to correct dehydration and support circulation
- Assisted feeding — once the gut is moving and the rabbit is stable, syringe-feeding a critical care food such as Oxbow Critical Care maintains nutrition and stimulates digestion
- Treatment of the underlying cause — dental work, management of urinary problems, or other interventions as needed
- Surgery — in cases where radiographs confirm a true obstruction that cannot be resolved medically, emergency surgery may be necessary
Hospitalisation for 24 to 48 hours or longer is common in moderate to severe cases. The sooner treatment begins, the better the prognosis.
Prevention: Hay Is the Most Important Thing
The single most effective measure you can take to reduce the risk of GI stasis is ensuring your rabbit has unlimited access to good-quality hay at all times. Hay should make up approximately 80 percent of a rabbit's diet. The long fibre in hay is what keeps the gut moving — pellets, fresh vegetables, and treats cannot replace it.
Alongside unlimited hay, provide daily exercise and opportunities for enrichment to reduce stress. Regular veterinary dental checks — at least annually — are important for catching dental disease before it suppresses appetite. Keep fresh water available at all times. Minimise sudden changes in environment or routine where possible.
GI stasis is a genuine emergency every time it occurs. Knowing the signs and acting immediately — calling your vet without delay — is the difference between a rabbit that recovers and one that does not.
