Nausea

Nausea can be a common symptom experienced by patients with ME/CFS. It may be mild and relapsing or severe and constant. Possible causes of nausea in ME/CFS patients include orthostatic intolerance, gut inflammation , and slower gastric motility.

Symptom recognition
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.

Possible causes
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.
