Alanine aminotransferase (ALT) was 24, aspartate aminotransferase (AST) 41, and alkaline phosphatase 66.

The patient was admitted to the hospital with suspicion for marijuana hyperemesis syndrome. The patient received treatment with intravenous fluids, and antiemetics. Another clinical diagnosis was leukocytosis. The admitting physician indicated that the patient had elevated white blood cell count during previous admissions. In addition, the admitting physician stated that the patient's urinalysis and chest x-ray were negative. The elevated blood pressure was attributed to stress.
During the hospital stay, the patient's clinical condition significantly improved. Nausea and vomiting resolved. The final diagnosis was cyclic vomiting syndrome.
Since the patient's clinical condition significantly improved, she was transitioned to outpatient care.

There was no evidence of severe dehydration, kidney failure, or electrolyte abnormalities. The patient's symptoms improved within a short period of time, and she was able to maintain oral hydration.
Taking into consideration all these facts, neither the severity of the patient's condition nor the complexity of services provided rose to the acute inpatient level of care.
