Patient Q&A Section

What are the signs of vomiting?

"Often nausea and vomiting are not associated externally or internally with any gastrointestinal problem, and can be misreported as a gastrointestinal problem. A history of recurrent vomiting is a typical presenting complaint. It is not uncommon to confuse the nausea and vomiting that precedes the emesis associated with gastrointestinal (GI) pathology, or that occurs, particularly in children, as a sequelae of GI disease affecting other organs, as nausea and vomiting. The most common identifiable cause of nausea and vomiting is motion sickness (the 'Space Ship vertigo'). It is important that the patient and the physician pay vigilant attention to the history of recurrent and recent vomiting, and that clinicians seek other possible causes of nausea and vomiting." - Anonymous Online Contributor

What is vomiting?

"In a young person, nausea and vomiting are usually the only symptom of an acute illness, and there are no major problems caused by vomiting. In an elderly person, vomiting can lead to dehydration. Elderly adults need to look for different symptoms when eating together." - Anonymous Online Contributor

How many people get vomiting a year in the United States?

"Overall, approximately 3% of people in the USA get vomit more than once a year. Patients' ages, sexes, and races were found to affect the incidence of vomiting. As a result of the increased level of vomiting in the USA, hospitals in the USA would be able to save approximately $8 billion in hospital costs on gastroenteritis-preventative drugs and devices." - Anonymous Online Contributor

What causes vomiting?

"The most common causes of vomiting in general are a wide variety of gastrointestinal causes ranging from dehydration to poisoning, which require medical attention. There are many other causes that affect the patient only when they are vomiting, such as gastrointestinal infection, intoxication, or medications." - Anonymous Online Contributor

Unverified Answer

Can vomiting be cured?

"Vomiting is a common, severe medical condition which may be caused more by nausea than vomiting itself. No test or procedure can determine whether or not vomiting is due to nausea. Vomiting is a symptom, which should be treated for nausea. To help with nausea, a doctor or nurse must first diagnose the underlying cause of excessive vomiting. The treatment of nausea, in both paediatric and adult patients, depends on the underlying cause of vomiting." - Anonymous Online Contributor

What are common treatments for vomiting?

"People with vomiting disorder can benefit from an approach that incorporates medication options from nausea, migraine, and gastroesophageal reflux disease. The approach emphasizes using pharmacologic and pharmacotherapeutic interventions in addition to the physiologic approach." - Anonymous Online Contributor

Unverified Answer

What is the average age someone gets vomiting?

"Approximately 25% of respondents who reported vomiting had a history of vomiting by the age of 11 years, suggesting that some vomiting can begin early in life. A history of childhood earache with regular vomiting does not increase the risk of vomiting. We suspect that the majority of vomiting occurs after the age of 11 years, but this study is limited by its cross-sectional design." - Anonymous Online Contributor

Unverified Answer

Who should consider clinical trials for vomiting?

"Patients should be counseled on the risks of research participation. Patients should have baseline EKG before study enrollment. They should be screened for any medical history that would preclude participation, such as coronary disease. They should be asked to avoid opioids during the study period. They should be counseled on the use of study results to help them make decisions about treatment. These considerations can minimize the risk of research participation in a new-onset, life-threatening or otherwise difficult disease like malignant vomiting." - Anonymous Online Contributor

Have there been other clinical trials involving ondansetron oral solution?

"Although ondansetron had proven to be effective in reducing gastro-oesophageal reflux in clinical use, we did not find any data on the use of the oral solution regarding its therapeutic and symptomatic effect when the stomach was empty." - Anonymous Online Contributor

Unverified Answer

Does ondansetron oral solution improve quality of life for those with vomiting?

"A single oral spray (20 mg) of ondansetron (Zofran) improved quality of life in all but one of the trial participants. Therefore, ondansetron nasal spray was not included in the pooled analysis of the three trials, since few patients received nasal spray; thus, the use of nasal spray for nausea and emesis was based on a single small randomized pilot study." - Anonymous Online Contributor

Unverified Answer

Has ondansetron oral solution proven to be more effective than a placebo?

"Ondansetron in a 1.0 mg oral solution significantly and rapidly reduces symptoms of nausea and vomiting without having adverse effects. The effect of ondansetron was similar to that of dimenhydrinate in the reduction of the number of episodes and the intensity of vomiting episodes. However, the number of patients who received ondansetron was considerably greater than that of dimenhydrinate, which raises concerns regarding the feasibility of using the former drug in actual clinical practice." - Anonymous Online Contributor
