Abstract

OBJECTIVE: To review the effectiveness of alpha-glucosidase inhibitor (AGI) therapy in the treatment of hypoglycemia after Roux-en-y gastric surgery.

METHODS: Retrospective case review.

RESULTS: Four patients who previously underwent Roux-en-y gastric bypass were evaluated because of severe symptomatic postprandial hypoglycemia that was unresponsive to a low-carbohydrate diet. Mixed-meal testing confirmed hyperinsulinemia. Other causes of hypoglycemia were ruled out by a combination of clinical examination, endocrine testing, and computed tomography imaging. Symptomatic hypoglycemia resolved in all 4 patients after AGI therapy was started. One patient could not tolerate long-term therapy because of a rash. The other 3 patients were followed for between 5 and 48 months and remained free of symptomatic postprandial hypoglycemia.

CONCLUSION: AGI therapy is effective in the long-term treatment of post-Roux-en-y hypoglycemia in patients unresponsive to a low-carbohydrate diet. To our knowledge, this is the first report documenting the long-term usefulness of this therapy in a series of patients.
