Efficacy of oral glucose tolerance testing of pregnant women post bariatric surgery

Abstract

Worldwide, a large proportion of childbearing women are overweight or obese, and it is becoming increasingly common for pregnant women to have undergone bariatric surgery before conceiving. Women with a history of sleeve gastrectomy may not be able to undertake the oral glucose tolerance test, due to the risk of dumping syndrome. There is limited research on the effects of weight loss surgery on the pregnancy oral glucose tolerance test and conducting this test on a woman who has had bariatric surgery may be an inadequate form of diagnosing gestational diabetes mellitus. A cost-effective alternative to an oral glucose tolerance test is to monitor pre-and post-meal blood glucose levels.
