Upside-down stomach represents a critical and rare manifestation of hiatal hernias. Here we report on a 60-year-old male patient who was admitted to our hospital with epileptic seizures and dehydration. Laboratory tests revealed severe metabolic alkalosis (pH 7.56) with low potassium (2.7 mmol/l), hypochloremia (<60 mmol/l), increased hematocrit (53%) and high levels of serum creatinine (651 µmol/l). Based on a history of recurrent vomiting, gastroscopy and computed tomography were performed. Both diagnostics showed an upside-down stomach with signs of incarceration. Upon infusion of sodium chloride 0.9%, acid-base state, electrolyte balance and renal function became improved. Subsequently, the patient was referred to the department of surgery for hiatoplasty with fundoplication. This case report highlights severe metabolic and neurological disorders as unusual and life-threatening complications of an upside-down stomach.
