Achtergrond van het onderzoek
Bariatric surgery is currently the only therapy leading to sustained significant weight loss together with high percentages of remission of diabetes and other co-morbidities.
These impressive beneficial effects however can come at a price. One of the side effects is the development of postprandial hyperinsulinemic hypoglycemia, also called post bariatric hypoglycemia, PBH. Treatment approaches for PBH include dietary modifications, pharmacologic interventions and, possibly, surgical re-intervention or continuous tube feeding. Literature on the effect of treatment of PBH is scarce. The aim of this study is to evaluate the effect of different types of treatment for PBH, including medical therapy and/or surgical procedures, in terms of efficacy, tolerability and side effect in daily life. Objective : To retrospectively evaluate the effect of current medical treatment and the four surgical procedures for PBH on the resolution of hypoglycemic events and side effects in daily practice.Patients after gastric bypass surgery with PBH and with hypoglycemic episodes despite adequate dietary advice who were referred to either an endocrinologist or a surgeon from the Centrum Obesity North-Netherlands (CON) at Medical Center Leeuwarden, University Hospital Groningen and AmsterdamUMC. Inclusion criteria : (Roux-en-Y gastric bypass) RYGB or OAGB (mini-gastric bypass), documented hypoglycemia with self-measured glucose (SMBG) < 3.0 mM, blinded continuous glucose monitoring (cgm) 2.8 mM or Meal Test ( < 3.0 mM, neuroglycopenic symptoms with resolution of symptoms after normalization of blood glucose. Hypoglycemic episodes despite adequate dietary advice and interfering with daily activities, socially and/or work-related and willingness to participate. Study design : Retrospective observational study combined with a short questionnaire.
