Nutrition in Pregnancy Following Bariatric Surgery

Nutrients. 2017 Dec 8;9(12):1338. doi: 10.3390/nu9121338.


The widespread use of bariatric surgery for the treatment of morbid obesity has led to a dramatic increase in the numbers of women who become pregnant post-surgery. This can present new challenges, including a higher risk of protein and calorie malnutrition and micronutrient deficiencies in pregnancy due to increased maternal and fetal demand. We undertook a focused, narrative review of the literature and present pragmatic recommendations. It is advisable to delay pregnancy for at least 12 months following bariatric surgery. Comprehensive pre-conception and antenatal care is essential to achieving the best outcomes. Nutrition in pregnancy following bariatric surgery requires specialist monitoring and management. A multidisciplinary approach to care is desirable with close monitoring for deficiencies at each trimester.
