Cyclic vomiting syndrome
Prodromal or concurrent signs and symptoms of cyclic vomiting syndrome include nausea, pallor, abdominal or epigastric pain, lethargy, headache, anorexia, diarrhea, photophobia, and fever. Studies show a link between cyclic vomiting syndrome and migraine headaches. Other associations include metabolic (food allergy), mitochondrial, catamenial, and endocrine disorders.
