Severe hyperchloremic acidosis complicating jejunoileal bypass.
In summary, severe hyperchloremic acidosis developed in two patients as a late complication after jejunoileal bypass for morbid obesity. This acidosis was associated with episodes of dizziness, ataxia, headache, weakness, confusion and transient loss of consciousness. Recognition of this symptom complex in the patient with a jejunoileal bypass should suggest metabolic acidosis as a complication of this surgical procedure. Bicarbonate replacement provided prompt, but temporary, improvement in the symptoms and the acidosis. Revision of the intestinal bypass was required for correction. Special studies to rule out renal tubular acidosis were performed and definitely excluded the kidney as a source of the acidosis.
