Summary
Cyclic vomiting syndrome (CVS) is a challenging condition often diagnosed late. Early management of risk factors and appropriate treatment can reverse symptoms and improve patient quality of life.
Area of Science:
- Gastroenterology
- Neurology
Background:
- Cyclic vomiting syndrome (CVS) is an underdiagnosed condition impacting patients' lifestyles.
- Recurrent episodes of nausea, vomiting, and abdominal pain lead to frequent emergency department visits.
- Delays in diagnosis and treatment cause significant physical and financial hardship.
Purpose of the Study:
- To review diagnostic criteria, pathophysiology, risk factors, and treatment for CVS.
- To summarize the latest literature on CVS diagnosis and management.
- To provide a resource for clinicians managing CVS.
Main Methods:
- Literature review of recent data on CVS diagnosis and management.
- Analysis of studies on risk factors and pathophysiology.
- Summary of expert opinions on future research and treatment.
Main Results:
- CVS is characterized by recurrent episodes of nausea, vomiting, and abdominal pain.
- Pain management with certain medications suggests a potential central nervous system (CNS) origin.
- MRI brain changes in CVS patients may offer insights into pathophysiology.
Conclusions:
- Most cases of CVS are reversible with risk factor management and appropriate treatment.
- A standardized treatment regimen is needed due to delays in therapy initiation.
- Further research into CNS origins and MRI findings can improve understanding and management of CVS.

01:22Pathophysiology of Vomiting
2.6K
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...

Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

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...
