吸收不良
Sign in to saveAlso known as malabsorption syndrome, malabsorption syndromes, obsolete malabsorption syndrome
Malabsorption is a state arising from abnormality in absorption of food nutrients across the gastrointestinal (GI) tract. Impairment can be of single or multiple nutrients depending on the abnormality. This may lead to malnutrition and a variety of anaemias.

吸收不良（英語：Malabsorption）是由胃肠道对食物营养素的吸收异常引起的一种状态。根据异常情况，损害可以是单一或多种营养素。可能导致营养不良和各种贫血。 正常情况下，人体胃肠道消化和吸收膳食营养素的效率非常高。一个成年人一天摄入的典型西方饮食包括大约100克脂肪、400克碳水化合物、100克蛋白质、2升液体，以及所需的钠、钾、氯化物、钙、维生素和其他元素。唾液、胃、肠、肝和胰腺分泌物向肠道内容物中额外添加7-8升含蛋白质、脂质和电解质的液体。小肠和大肠将这种巨大的负荷减少到200克以下的粪便，其中含有少于8克的脂肪、1-2克的氮，以及少于20 mmol的Na+、K+、Cl-、HCO3-、Ca2+、或Mg2+。 如果营养消化和吸收的复杂过程中涉及的许多步骤中的任何一个受到损害，则可能会出现肠道吸收不良。 如果异常涉及吸收过程中的一个步骤，如原发性乳糖酶缺乏症，或者如果疾病过程仅限于非常近端的小肠，则可能仅发生单一营养素的选择性吸收不良。当疾病过程广泛时，会出现多种膳食营养素的普遍吸收不良，从而干扰一些消化和吸收过程，如广泛累及小肠的乳糜泻。
