Cyclic vomiting syndrome is a condition in which there are episodes of severe vomiting without any noticeable cause. As the name suggests, the episodes occur in a cycle. Each episode resembles the previous in terms of duration, intensity, symptoms and time of initiation. You or your child may experience the symptoms for hours in a day followed by a symptom-free episode on the next day. It was originally believed to affect children only, but it can affect people of any age.
The incidence of cyclic vomiting syndrome in adults is rising and study suggests almost 2% of school going kids are affected by this. A link between cyclic vomiting syndrome and migraines has been proposed. Often, you may have to take complete bed rest for days due to severe vomiting.
Diagnosis is difficult as vomiting is a non-specific symptom that could be indicative of a variety of disorders. Treatment focuses on symptom management and lifestyle modifications to avoid the triggering factors. Symptoms can also be managed by anti-vomiting medications and migraine therapies.
Usually, a vomiting episode is succeeded by a symptom-free episode while in some people, mild to moderate nausea or pain in stomach or extremities is reported between episodes. Vomiting that last longer can cause severe loss of fluids and electrolytes resulting in fatal dehydration. Some common symptoms of dehydration are:
Unusually light skin (paleness)
Tiredness and lack of vigor
It’s not clear what causes cyclic vomiting syndrome but it may be triggered by:
Diagnosis of cyclic vomiting syndrome is often difficult due to absence of specific symptoms.
After you visit your primary care doctor or your child's pediatrician, you may be referred immediately to a gastroenterologist (a specialist in digestive disorders). If you have continuous severe vomiting, seek immediate medical care.
How to prepare yourself for the visit?
Getting prepared for the visit can optimize the therapy and help make the visit more fruitful.
List out all the symptoms. Mention duration, frequency of vomiting and triggering factors
Write down your key medical information.
Write down the names of all your medications, vitamins or supplements.
Make a list of the questions to ask your doctor. Some typical questions can be:
What could be the most likely cause of these symptoms?
Are any tests needed?
Is this condition temporary or long lasting?
What are the treatment options?
Can any medication help?
Is it necessary to follow any dietary restrictions?
What your doctor wants to know?
A clear talk with your doctor can optimize the therapy and improve the outcomes. Prepare yourself to answer some essential questions from your doctor. Your doctor might ask you typical questions like:
When did the symptoms start appearing?
Can you tell me about the frequency of vomiting and duration of an episode?
Is vomiting accompanied by abdominal pain?
Is your episode preceded by any warning signs, such as loss of appetite or feeling unusually tired, or any triggering factors, such as intense emotions, illness or menstruation?
Is there a history of any other medical problems, including mental health conditions?
What treatments (over-the-counter medications and home remedies) are being administered for other conditions?
Does anything improve the symptoms or reduce the duration of an episode?
Has anyone in your family suffered from cyclic vomiting syndrome or of migraines?
What you can do in the meantime?
The doctor will observe the episode of vomiting, if possible. But if it’s over, s/he may recommend increased fluid intake, proper rest and an easily digestible diet to promote recovery. You may also avoid or ask your child to avoid caffeine.
No test can confirm the diagnosis but tests can be performed to rule out other possible causes of vomiting. Diagnosis starts with review of your or your child’s medical history followed by a physical exam. The doctor may also recommend:
Imaging studies such as endoscopy, CT scan or magnetic resonance enterography to determine if there are other digestive problems.
Motility tests to assess how the food you or your child takes moves along the gastrointestinal tract.
Laboratory tests to detect problems with thyroid and other metabolic conditions, if any
MRI to determine if a brain tumor and other central nervous system disorders are present
Migraine medications: If the vomiting episodes are frequent and persistent, migraine medications may be prescribed to control, or less commonly to prevent episodes of cyclic vomiting.
Behavioral therapy: Studies suggest that depression or anxiety occur in approximately half of the victims of cyclic vomiting syndrome. However, there is no clear link between depression or anxiety and cyclic vomiting episodes as the cause and effect of each other. Behavioral therapy may help you or your child manage depression or anxiety.
The best way to prevent cyclic vomiting syndrome episodes is to avoid personal triggers, which vary from person to person. People with this syndrome are aware of the triggers that initiate vomiting episodes. In cases when episodes are severe requiring hospitalization or frequent (occur more than once a month), you may need to take preventive medications as prescribed by the doctor. You may follow these lifestyle modification tips:
Get enough sleep
Keep calm and keep your excitements under control
Avoid trigger foods, such as cheese and chocolate
Have three small meals and three snacks in a day at almost same times every day
