Xu points out that when pregnant women have elevated blood sugar levels during their pregnancy, their babies may have "excessive nutrition" over long periods, so that they develop macrosomia or "big baby syndrome" (which is usually defined as giving birth to a child over four kilograms), and they often have ailments related to low blood sugar or electrolyte imbalances.
徐振傑指出，若母體在懷孕時血糖值過高，寶寶就有可能因長期「過度營養」而發展成「巨嬰」（通常指體重超過 4,000 克的寶寶）。
