Gastroenteritis is a medical term referring to inflammation of the gastrointestinal tract, usually the stomach and intestines. It can be caused by infection with bacteria, viruses, parasites, or reactions to medications or new foods. It often involves abdominal discomfort or pain, diarrhea and/or vomiting.
"Most cats with gastroenteritis will have intermittent episodes of vomiting and diarrhea."
Most cats with gastroenteritis will have intermittent episodes of vomiting and diarrhea. The vomit may contain foamy, yellowish bile, especially after the stomach has been emptied. Many owners will observe "dry heaving" or "gagging" after their pet eats or drinks. Characteristically, there will be large volumes of diarrhea produced three to six times a day. The diarrhea may have a "soft ice cream" consistency and is often pale in color. Many cats will be tender when picked up around the abdomen or will resist handling of the stomach and hindquarters. Most cats affected with gastroenteritis will appear less active and have a decreased appetite. A low-grade fever is common. Dehydration can occur quickly if the vomiting and diarrhea persists for more than twenty-four hours.
Gastroenteritis is a diagnosis of exclusion. This means that your veterinarian will eliminate or rule out other more serious causes of the clinical signs before making a general diagnosis such as gastroenteritis. The first step toward determining what is causing a pet's vomiting, diarrhea, lethargy and other associated clinical signs are a good medical history.
Some key information in your cat's medical history includes:
After obtaining the medical history, your veterinarian will perform a thorough physical examination. Your veterinarian will look for evidence of dehydration, abdominal pain or tenderness, bloating or gas, swellings, or any other physical abnormality. Your cat's temperature and other vital signs will be recorded.
At this stage, diagnostic testing will be recommended and may include:
"Your cat's specific diagnostic workup will be determined by the severity and duration of clinical signs, medical history and physical examination."
Your cat's specific diagnostic workup will be determined by the severity and duration of clinical signs, medical history and physical examination. Once the diagnostic tests are complete and other causes of the clinical signs have been eliminated, treatment will be prescribed.
There are many causes of the symptoms of vomiting and diarrhea in cats. Some of the more common conditions that your veterinarian will attempt to eliminate during the diagnostic workup include:
This is only a partial listing of some of the more serious conditions that can cause vomiting and diarrhea in cats. Your veterinarian may discuss other possibilities based on your pet's specific condition.
The principal treatment of gastroenteritis is rehydration and restoration of blood electrolyte balance (sodium, potassium and/or chloride). Depending on the degree of dehydration, this fluid replacement may be given orally, subcutaneously or by intravenous (IV) treatment.
Antibiotics may be administered if the clinical signs are severe or if diagnostic tests suggest a bacterial infection. Antidiarrheal agents or drugs to alter intestinal motility (activity) may be used in certain conditions, after intestinal obstruction or other mechanical and anatomical issues have been ruled-out. If your pet is experiencing severe colitis, motility-modifying agents are generally not recommended.
Food (and sometimes water) is often withheld during the initial stages of treatment and then slowly reintroduced. Small, frequent feedings of a bland diet are generally prescribed. Your veterinarian will advise you on the best diet to feed your pet for a speedy recovery.
Most cases of acute gastroenteritis improve rapidly after rehydration. If the vomiting and diarrhea do not improve significantly within forty-eight hours of treatment, the diagnosis should be re-evaluated.
