Chronic vomiting may be a symptom of many health issues, some of which are quite serious. Sometimes, chronic vomiting may be caused by anxiety or other emotional issues. Some drugs also can cause vomiting as a side effect. Chronic vomiting may also be a symptom of illnesses including gastrointestinal disorders, cancer, epilepsy, and even allergies. When experiencing chronic vomiting, it is important to consult with a health care provider for a proper diagnosis.
Many children and adults experience vomiting due to food allergies, which can be diagnosed by a physician. The most common allergy-causing foods include milk and eggs. Someone with food allergies may experience other symptoms as well, such as hives or swelling.

Continual bouts of vomiting that remain undiagnosed and untreated may lead to severe dehydration. This is why it is essential to obtain a professional diagnosis as soon as possible. A doctor may take a medical history and run a series of diagnostic tests on a patient suffering from vomiting.

When chronic vomiting or CVS occurs in young children, it is often associated with anxiety. The child who experiences symptoms of CVS may feel stressed at school or from family related issues. When a child experiences gastrointestinal symptoms such as chronic vomiting, his pediatrician will test for a medical cause. If medical disorders have been ruled out, counseling may be recommended for a child under stress.
