Some premature babies have a temporary form of lactose intolerance because their bodies are not yet producing lactase 一些早产的宝宝会暂时的有乳糖不耐受症状是因为他们体内还未开始分泌乳糖分解酶。
This disorder , apparent within 10 days of birth , occurs when brush - border lactase activity ( required for the digestion of lactose ) in the small intestine is low or absent at birth and is characterized by diarrhea and malabsorption 此病是由于宝宝出生时小肠内的乳糖分解酶素活性很低或没有活性,病症通常在宝宝出生10天内显现:拉肚子以及吸收不良。
