Cyclical vomiting syndrome
Cyclical vomiting syndrome (CVS) is a disorder characterised by recurrent episodes of severe vomiting that can last for hours or even days. The symptoms typically include intense nausea, vomiting multiple times an hour, abdominal pain, and sometimes other symptoms like headaches or dizziness.
The exact cause of CVS is not fully understood, but it may be linked to genetic factors, migraines, or stress. Certain triggers, such as specific foods, infections, or emotional stress, can provoke episodes in some individuals.
Diagnosis of CVS often involves ruling out other conditions that could cause similar symptoms. This may include medical history reviews, physical examinations, and various tests to exclude other gastrointestinal or metabolic disorders.
Treatment for CVS focuses on managing symptoms and preventing future episodes. This can include medications to control nausea and vomiting, lifestyle changes, and identifying and avoiding triggers. Support from healthcare professionals, including dietitians and mental health specialists, can also be beneficial for those affected by the condition.
