Context: Roux-en-Y Gastric bypass (RYGB) is an effective way to induce sustainable weight loss. This operation can be complicated by late dumping, also known as postgastric bypass hyperinsulinemic hypoglycemia. Much is still unknown on its prevalence and its pathophysiology.Objective: To study the prevalence and the main driving mechanisms behind the occurrence of hypoglycemia after a mixed meal tolerance test (MMTT) in patients with primary RYGB. Design...

Introduction: The endocrinologist is confronted with an increasingly large population of postbariatric patients who present with endocrine problems. One of these is early dumping, a complication that may be the result of increased entero-endocrine activity. To address the prevalence of early dumping and to gain further insight into its pathophysiology, we performed a Mixed Meal Tolerance Test (MMTT) in a random sample of patients after Roux-en-Y gastric bypass (RYGB).<p cl...

Introduction: Thyroid disorders are generally diagnosed based on thyroid stimulating hormone (TSH) outside the reference interval (RI), and subsequent free thyroxine (FT4) concentrations. Most laboratories do not provide age-specific RIs for TSH and FT4 beyond childhood, although it is known that TSH concentrations vary with age which may be important to take into account. Therefore, we aimed to establish age-specific RIs for TSH and FT4 throughout life using an indirect metho...
