  If the condition is not treated, episodes usually occur four to 12 times per year. Between attacks, vomiting is absent, and nausea is either absent or much reduced. However, many affected people experience other symptoms during and between episodes, including pain, lethargy, digestive disorders such as gastroesophageal reflux and irritable bowel syndrome, and fainting spells (syncope). People with cyclic vomiting syndrome are also more likely than people without the disorder to experience depression, anxiety, and panic disorder. It is unclear whether these health conditions are directly related to nausea and vomiting. […] Cyclic vomiting syndrome is often considered to be a variant of migraines, which are severe headaches often associated with pain, nausea, vomiting, and extreme sensitivity to light and sound. Cyclic vomiting syndrome is likely the same as or closely related to a condition called abdominal migraine, which is characterized by attacks of stomach pain and cramping. Attacks of nausea, vomiting, or abdominal pain in childhood may be replaced by migraine headaches as an affected person gets older. Many people with cyclic vomiting syndrome or abdominal migraine have a family history of migraines.

  https://emedicine.medscape.com/article/933135-clinical

  Cyclic vomiting syndrome (CVS) is characterized by recurrent, discrete, stereotypical episodes of rapid-fire vomiting between varying periods of completely normal health. This on-and-off stereotypical pattern of vomiting is nearly pathognomonic of CVS. […] Although periods of complete normality typically occur between episodes, many adult patients lose the cyclic pattern of symptoms over time, and 63% of them develop inter episodic symptoms (often nausea) between episodes; this pattern is termed coalescence. […] The vomiting in CVS is typically much more severe and intermittent than that observed in gastroesophageal reflux. […] The stereotypical on-off pattern often begins with a prodrome of nausea and pallor. Vomiting peaks in the first hour and then begins to decline over the ensuing 4-8 hours, lasting a mean of 24 hours (median, 43 hours).

  Cyclic vomiting syndrome (CVS) is a chronic disorder of gut-brain interaction (DGBI) diagnosed by clinical criteria called Rome criteria as there are no biomarkers (blood tests or x-ray tests) that can be used to detect this condition. CVS includes stereotypic episodes of severe nausea and vomiting that can last from a few hours up to a week. Other symptoms include abdominal pain, feelings of panic, feeling hot and cold, sweats and diarrhea. […] The symptom episodes of CVS tend to follow the same pattern for each individual patient over time. The symptom episodes are characterized by four phases: prodromal phase- During this phase, the patient may experience intense sweating and nausea or feel like an episode of vomiting is about to start. emetic (vomiting phase)- This phase is characterized by intense, persistent nausea, vomiting, and other symptoms (abdominal pain, prostration, and lethargy). This phase lasts from hours to days. recovery phase- This phase begins with the settling down of nausea and ends when hunger, tolerance of oral intake, and vigor return to normal. inter-episodic phase- This phase occurs between vomiting episodes when the patient is relatively symptom-free. This phase typically lasts weeks to months. […] Though many patients return to normal health in between episodes, some patients continue to experience mild nausea and/or abdominal pain in between episodes.

  Cyclic vomiting syndrome (CVS) is a chronic disorder of gut-brain interaction (DGBI) and is characterized by recurrent episodes of severe nausea, vomiting, and often, abdominal pain. Patients are usually asymptomatic in between episodes. […] Most patients (~ 93%) have a prodromal phase. Symptoms during this phase can include nausea, abdominal pain, diaphoresis, fatigue, weakness, hot flashes, chills, shivering, increased thirst, loss of appetite, burping, lightheadedness, and paresthesia. Some patients report a sense of impending doom and many have symptoms consistent with panic. If untreated, this progresses to the emetic phase and patients have unrelenting nausea, retching, vomiting, and other symptoms. During an episode, patients may vomit up to 20 times per hour and the episode may last several hours to days. During this phase, patients are sometimes described as being in a “conscious coma” and exhibit lethargy, listlessness, withdrawal, and sometimes disorientation.

  Nausea and vomiting have many etiologies, and cyclic vomiting syndrome (CVS) is not the first diagnosis that comes to mind for an adult presenting to the emergency department. […] Adults with CVS almost always receive fragmented care, and a diagnostic delay of five to six years from the onset of symptoms is typical. […] CVS is characterized by four phases. Each attack begins with a prodromic phase, followed by an emetic phase, and then a recovery phase. Between episodes, there is a well phase, during which the patient is typically, but not always, asymptomatic. […] Sweating and nausea are common during the prodrome phase, which is similar to the prodrome experienced by migraine sufferers. […] Episodes often begin suddenly in the early morning. Patients describe this sudden onset as feeling like a switch flipped, which suggests a nervous system state change.

  Cyclic vomiting syndrome (CVS) in adults is a disorder characterized by recurrent abrupt bouts of nausea, vomiting and abdominal pain separated by variable periods of normal health. […] This alternating pattern of disease and disease-free periods distinguishes CVS from other disorders of nausea and vomiting. […] Adult patients typically have been symptomatic for a long time before diagnosis. Patients often remain undiagnosed for some time due to lack of recognition of this clinical entity with reports suggesting a delay in diagnosis for as long as 8-21 years following onset of the symptoms. […] Over time without appropriate specific treatment, CVS cycles slowly begin to coalesce and become closer together and this can confuse the presentation and suggest more of a chronic entity such as gastroparesis.

  Cyclic vomiting syndrome is a disorder that causes recurrent episodes of nausea, vomiting, and tiredness (lethargy). This condition is diagnosed most often in young children, but it can affect people of any age. […] The episodes of nausea, vomiting, and lethargy last anywhere from an hour to 10 days. An affected person may vomit several times per hour, potentially leading to a dangerous loss of fluids (dehydration). Additional symptoms can include unusually pale skin (pallor), abdominal pain, diarrhea, headache, fever, and an increased sensitivity to light (photophobia) or to sound (phonophobia). In most affected people, the signs and symptoms of each attack are quite similar. These attacks can be debilitating, making it difficult for an affected person to go to work or school. […] Episodes of nausea, vomiting, and lethargy can occur regularly or apparently at random, or can be triggered by a variety of factors. The most common triggers are emotional excitement and infections. Other triggers can include periods without eating (fasting), temperature extremes, lack of sleep, overexertion, allergies, ingesting certain foods or alcohol, and menstruation.

Injury to the food tube. The stomach acid that comes up with the vomit can damage the tube that connects the mouth and stomach (esophagus). Sometimes the esophagus becomes so irritated it bleeds. Tooth decay. The acid in vomit can corrode tooth enamel. […] Many people know what triggers their cyclic vomiting episodes. Avoiding those triggers can reduce the frequency of episodes.

  Relentless vomiting can lead to significant dehydration. Signs of dehydration include thirst, much less urination, a dry mouth, and irritability or difficulty staying awake. A child with symptoms of dehydration should see a health care provider immediately. […] Vomiting can cause severe dehydration that can be life threatening and lead to hospitalization. Cyclic vomiting attacks can last for days and be extremely debilitating for the child and disruptive to family life. On average, these children miss about three weeks of school annually and suffer from significant anxiety due to their condition. […] Many children will outgrow CVS around puberty, but about 75% will likely develop migraine headaches later in life. Some children develop chronic daily nausea.

  Cyclic vomiting syndrome (CVS) is characterized by recurrent, discrete, stereotypical episodes of rapid-fire vomiting between varying periods of completely normal health. This on-and-off stereotypical pattern of vomiting is nearly pathognomonic. […] Most published series indicate that CVS lasts an average of 2.5-5.5 years, resolving in late childhood or early adolescence. A few patients continue to be symptomatic through adulthood. […] A survey by Abu-Arafeh et al found the mean ages of children with CVS, abdominal migraines, and migraine headaches to be 5.3 years, 10.3 years, and 11.5 years, respectively. This finding supports the developmental progression from vomiting to abdominal pain to headache. […] Although patients are well about 90% of the time, CVS can be medically and socially disabling. More than 50% of patients require intravenous (IV) fluids, compared with less than 1% of patients with rotavirus gastroenteritis. The average annual cost of testing, treatment, and absenteeism totals $17,000. Children miss an average of 24 school days per year and often need home tutoring or, occasionally, home schooling. Additionally, because of its frequency during times of excitement, CVS has ruined many birthdays, holidays, and vacations. […] In adults, substantial morbidity is associated with CVS, perhaps because of lack of awareness and resultant delays in diagnosis. In a study of 41 CVS patients, Fleisher found that 32% were completely disabled at the time of diagnosis.

  If the condition is not treated, episodes usually occur four to 12 times per year. Between attacks, vomiting is absent, and nausea is either absent or much reduced. However, many affected people experience other symptoms during and between episodes, including pain, lethargy, digestive disorders such as gastroesophageal reflux and irritable bowel syndrome, and fainting spells (syncope). People with cyclic vomiting syndrome are also more likely than people without the disorder to experience depression, anxiety, and panic disorder. It is unclear whether these health conditions are directly related to nausea and vomiting. […] Cyclic vomiting syndrome is often considered to be a variant of migraines, which are severe headaches often associated with pain, nausea, vomiting, and extreme sensitivity to light and sound. Cyclic vomiting syndrome is likely the same as or closely related to a condition called abdominal migraine, which is characterized by attacks of stomach pain and cramping. Attacks of nausea, vomiting, or abdominal pain in childhood may be replaced by migraine headaches as an affected person gets older. Many people with cyclic vomiting syndrome or abdominal migraine have a family history of migraines.

  Cyclic Vomiting Syndrome (CVS) is a disorder characterized by recurrent, stereotypic episodes of incapacitating nausea, vomiting and other symptoms, separated by intervals of comparative wellness. […] Age of onset ranged from 2 to 49 years. The duration of CVS at the time of consultation ranged from less than 1 year to 49 years. CVS episodes were stereotypic in respect of their hours of onset, symptomatology and length. Ninety-three percent of patients had recognizable prodromes. […] Deterioration in the course of CVS is indicated by coalescence of episodes in time. The prognosis of CVS is favorable in the majority of patients. […] The prodrome of a cyclic vomiting episode is important because it allows for attempts at aborting the emetic phase. Thirty-eight patients (93%) had recognizable prodromes.
