Summary
Cyclic vomiting syndrome (CVS) is more common than previously believed, particularly in adults, and is linked to migraines. Early diagnosis and systematic treatment are crucial for managing this disabling condition.
Area of Science:
- Gastroenterology
- Neurology
- Genetics
Background:
- Cyclic vomiting syndrome (CVS) is a functional disorder affecting all age groups.
- Previously considered rare with unknown causes, treatment relied on anecdotal evidence.
- Recent research indicates CVS is more prevalent than initially thought.
Purpose of the Study:
- To review the current understanding of cyclic vomiting syndrome.
- To highlight the association between CVS and migraine headaches.
- To emphasize the importance of prompt diagnosis and effective treatment strategies.
Main Methods:
- A comprehensive literature review was conducted.
- Searches were performed using internet and Medline databases.
- Data was compiled as of April 2006.
Main Results:
- CVS is more common than previously recognized, especially in adults.
- CVS shares features with migraine headaches and has a genetic link to mitochondrial DNA.
- Prompt diagnosis is essential to prevent morbidity, requiring exclusion of mimicking disorders.
Conclusions:
- CVS is recognized as a distinct disorder within the migraine spectrum.
- Effective treatment is achievable once patients receive a proper diagnosis.
- Increased research and recognition since the 1990s are improving outcomes for patients with CVS.

01:22Pathophysiology of Vomiting
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through interaction...
01:29Gastroesophageal Reflux Disease II: Clinical Features and Management
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.

01:20Gastrointestinal Motility Disorders
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...
01:23Gastritis III: Clinical Manifestations and Management
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

01:11Pyloric Obstruction
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
