Postprandial hypoglycemia secondary to dumping síndrome

Hipoglicemia posprandial secundaria a síndrome dumping

Hypoglycemia in non-diabetics has been defined as a post-prandial glucose level of less than 55 mg/dl which may be part of Whipple´s triad (symptoms of hypoglycemia, low plasma glucose and relief of symptoms with the correction of low glucose). It may be mediated by insulin or may not be mediated by insulin, with fasting (postabsorbative) or postprandial (reactive) manifestations. The incidence of complications, such as, postprandial hypoglycemia related to dumping syndrome, has increased with the use of bariatric surgery. A case is presented in a patient who underwent bariatric surgery experiencing postoperative postprandial hypoglycemia. Dumping syndrome was confirmed by fasting and mixed-meal tests. Discussion and Conclusions: hypoglycemia is a common medical emergency and is usually secondary to medications used to treat diabetes. However, it may be spontaneous in non-diabetics and may be associated with multiple clinical disorders. Postoperative dumping syndrome following bariatric surgery may be disabling, with early or late manifestations. Diagnosis is based on symptoms and functional and imaging studies which confirm postprandial hypoglycemia and a rapid gastric emptying. Initial treatment is based on dietary modification, although medical therapy or surgical intervention may be required in refractory cases. Thus, the selection of candidates to undergo bariatric surgery must be conducted by a multidisciplinary group.
