Pregnancy Preparation and Care After Bariatric Surgery with Melanie McGrice
What should women know about preparing for pregnancy after bariatric surgery? And how can nutrition during this time support both maternal health and a baby’s long-term development?
In this episode, Advanced Accredited Practising Dietitian, Melanie McGrice explains why the period before conception and through a child’s first two years is one of the most important windows for nutrition. She focuses on what women who have had bariatric surgery need to consider when planning a pregnancy, including weight stability, nutrient levels, and timing.
Melanie discusses why weight management can become more complex after pregnancy and how nutritional status before conception can shape fertility outcomes. She also explores how epigenetic programming may influence a baby’s future health.
Melanie breaks down practical guidance for bariatric patients who want to start or grow their family. She explains how to time weight loss before conception, what adequate protein and micronutrient intake looks like with a restricted stomach, and why the folate conversation is more nuanced than many prenatal supplements suggest.
For anyone navigating pregnancy preparation after bariatric surgery, this episode offers clear, evidence-based guidance on supporting both mother and baby during this critical stage.
