For a woman with a previous LGA birth weight, what percentile must it exceed before a consultation is required?

For a woman with a history of giving birth to a large for gestational age (LGA) infant, a consultation with a specialist is typically warranted when the current estimated fetal weight exceeds the 97th percentile. This percentile is significant in clinical practice as it indicates a higher than average weight that may pose increased risks for both the mother and the fetus. The association with prior LGA births raises concerns about recurrent patterns and potential complications, making additional evaluation essential.

When fetal weights are above the 97th percentile, healthcare providers often consider factors such as maternal health, gestational diabetes, or other conditions that might contribute to excessive fetal growth. This consultation serves to assess the need for closer monitoring, possible interventions, and to develop an appropriate delivery plan to ensure safety for both mother and baby.
