What causes vomiting?
Vomiting is not a disease but a symptom of many different diseases. Many cases
of vomiting are self-limiting after a few days. Less commonly, vomiting may
result from a serious illness, such as cancer. Even when vomiting is caused
by mild illnesses, it may lead to death of the animal if treatment is not begun
early enough to prevent severe fluid and nutrient losses.
How serious is vomiting in dogs?
When the dog is systemically ill (i.e. more than one body system is involved),
some of the following may be noted:
3. Loss of appetite
4. Abdominal pain
5. High fever
7. Blood vomiting
What types of tests are performed to find the cause?
If vomiting is associated with several of the above signs, your veterinarian
will perform a series of tests in the hope that a diagnosis may be made. When
this can be done, more specific treatment may be initiated. Diagnostic tests
may include radiography (x-rays) with or without barium, ultrasound scans, blood
tests, biopsies of the stomach and intestinal tract, and exploratory abdominal
surgery. Once the diagnosis is known, treatment may include special medications,
diets, and/or surgery.
If your dog does not appear systemically ill from the vomiting, the cause
may be less serious. Some of the minor causes of vomiting include stomach or
intestinal bacteria viruses, stomach or intestinal parasites, and dietary indiscretions
(such as eating garbage or other offensive or irritating materials). A minimum
number of tests are performed to rule out certain parasites and infections.
These cases may be treated with drugs to control the motility of the intestinal
tract, drugs that relieve inflammation in the intestinal tract, and, often,
a special diet for a few days. This approach allows the body's healing mechanisms
to correct the problem. Improvement is expected within 2-4 days; if this does
not occur, a change in medication will be made or further tests performed to
better understand the problem.
