Nausea is a sensation of unease and discomfort in the upper stomach with an involuntary urge to vomit. It may precede vomiting, but a person can have nausea without vomiting. When prolonged, it is a debilitating symptom.
Nausea is a relatively common symptom experienced by patients with ME/CFS. It can range from mild to severe and can be relapsing or constant.
Katrina Berne reports a prevalence of 60-90% for nausea (as well as a wider prevalence of 50-90% for IBS symptoms including diarrhea, nausea, gas, and abdominal pain).
Although nausea is not listed as a symptom necessary for diagnosis in any of the current case definitions, it is frequently listed as a secondary symptom in information for patients and physicians.
Severe nausea may be caused by the digestive motility disorder, gastroparesis, that can be a co-morbid condition with ME/CFS. Gastroparesis is a neuro-muscular abnormality that causes delayed gastric emptying which, in turn, causes a premature full feeling while eating, bloating, nausea, acid reflux, regurgitation, belching, and occasional vomiting.
