Matted Hair and Hairballs in the Stomach in Rabbits
Trichobezoars in Rabbits
A trichobezoar is a technical reference for a mat of hair that has been ingested, and that is often combined with thick or undigested food. It is located in the stomach and/or intestines.
It is not abnormal to find hair in a rabbit's stomach, since they self-groom, and this normally would not cause symptoms or be a cause for concern or a sign of disease. However, inspissated stomach contents (thick, dry, and less fluid and motile), which may include hair, is an abnormal finding and a cause for further inspection. The finding of inspissated contents or a mass of hair may suggest that your rabbit is receiving too little fiber in its diet, or that there is a problem with its gastrointestinal tract.
Unlike cats, which also can suffer from excessive trichobezoars, rabbits are not physically capable of vomiting the contents of their stomachs. For this reason, everything that goes into a rabbit's mouth must be able to pass through the digestive tract, otherwise, the presence of excess hair can lead to severe complications, such as intestinal blockage. If the issue is not resolved quickly, the condition can be fatal.
Symptoms and Types
The signs, symptoms, and type of trichobezoars suffered by the rabbit can depend largely on the causes for the disease and the severity of the problem. Some common signs and symptoms of matted hair in the stomach may include:
There are several causes for trichobezoars, or hairballs, in the stomachs of rabbits. These include improper nutrition, and dehydration of the stomach contents. Sometimes metabolic diseases, pain, or stress can contribute to the formation and accumulation of hairballs or matted hair in the stomach. Usually, the finding is that too little gastrointestinal motility is to blame for the collection of hair and other materials in the stomach. One of the culprits may be feeding the rabbit too little hay or coarse fiber, necessary for pushing contents through the digestive tract. Anorexia - an inability to eat -- or simply a prolonged poor appetite can also contribute to the problem.
There will always be conditions to rule out prior to diagnosing trichobezoars, or related conditions. Diagnostic imaging, such as what can be viewed on X-ray, will allow your veterinarian to investigate the functions of the colon and gastrointestinal tract, and to view the stasis (obstruction), or inability of the digestive tract to pass fecal matter through to the anus. Your doctor will need to determine if there is in fact an obstruction in the gastrointestinal tract, or in the motility, and whether a life-threatening emergency may exist. If an obstruction us found, emergency treatment will be necessary, as this can quickly because a life threatening situation.
In acute (sudden) cases, shock may occur, so it is important to take sensible action quickly. Distension of the stomach is usually clear, and a quick inspection by your veterinarian will find food and hair in the gastric contents. Ultrasound is an excellent diagnostic tool for visualization of the stomach's contents, and to confirm the diagnosis.
