Acarbose Therapy for Post-Bariatric Hypoglycemia

Mechanism of Action and Efficacy

• Acarbose inhibits α-glucosidase enzymes in the small intestine, slowing carbohydrate digestion and blunting postprandial hyperglycemia and subsequent hypoglycemia, as recommended by the American Diabetes Association 1

Monitoring and Dose Adjustment

• If hypoglycemia persists despite optimal acarbose dosing, consider alternative or additional therapies such as somatostatin analogues, according to the American Association of Clinical Endocrinologists 2

Special Considerations

• For hypoglycemia treatment while on acarbose, use glucose tablets or other monosaccharides rather than complex carbohydrates, as acarbose prevents the digestion of polysaccharides, as suggested by the European Association for the Study of Diabetes 3

Alternative Options for Refractory Cases

• If acarbose is ineffective or not tolerated, somatostatin analogues may be considered as they have shown effectiveness for post-bariatric hypoglycemia, as recommended by the American College of Endocrinology 2
