Causes of vomiting
Vomiting is only the symption - not the cause.
The most common causes of vomiting are dietary related, either through dietary indiscretion (e.g. overeating, eating overly rich or spoiled food) which causes acute (sudden) vomiting, or adverse food reactions (food allergies) which can cause chronic (long term and intermittent) vomiting.
However, there are a huge number of other causes arising from either the gastrointestinal system itself (stomach and small intestine) or secondary to disease elsewhere in the body (e.g. liver or kidney disease).
Within the stomach, possible causes include:
1. Gastritis (inflammatory disease)
2. Stomach ulceration
3. Stomach cancer
4. Obstruction (foreign bodies, telescoping of intestine)
5. Hiatal hernia (part stomach herniating through the diaphragm)
Possible causes within the intestine include:
1. Infectious diseases (e.g. parvovirus)
2. Worms
3. Inflammatory bowel disease
4. Intestinal cancer
Secondary causes of vomiting that are due to disease elsewhere in the body include:
1. Pancreatitis (infection or inflammation of the pancreas)
2. Peritonitis (infection in the abdominal cavity)
3. Hepatitis (liver inflammation)
4. Kidney failure
5. Pyometra (infection of the uterus)
6. Hormonal deficiencies or excesses (e.g. Addisons disease, Diabetes Mellitus, Septicemia, Calcium imbalance)
Other potential causes that do not fit into the above categories are drug reactions (e.g. digoxin, chemotherapy drugs, NSAIDs) and neurological disorders.
