In this "Mailbag" episode of Healthful Woman, Dr. Nathan Fox answers listener questions covering a range of pregnancy-related topics, from fetal growth and kidney findings to Braxton Hicks contractions and large-for-gestational-age babies. He breaks down complex medical concepts in plain language, reassuring listeners that many common findings, like a baby measuring in the seventh percentile or mild pyelectasis, are often benign while explaining when closer monitoring is warranted. The episode also tackles practical questions about core exercise during pregnancy and how diet does (and doesn't) affect glucose screening tests.
