The extent of intestinal absorption and malabsorption may be exactly stated by means of the method "generalized absorption". According to first-hand examinations an alteration of absorbing kinetics of D-xylose dependent on age could have been demonstrated. The velocity of absorption decreases in the elderly and the general absorbing process are prolonged. The extent of absorption restriction in the elderly are under physiological circumstances without clinical value. The health elder man disposes of the same power for a complete absorption of an offered substrate like the younger one. An increasing of cases with a malabsorption in the age may be explained by a increased multmorbidity in the elderly.
通过“广义吸收”方法可以准确说明肠道吸收和吸收不良的程度。根据第一手检查结果，已证实D-木糖的吸收动力学随年龄而改变。老年人的吸收速度下降，总体吸收过程延长。在生理情况下，老年人吸收受限的程度无临床意义。健康的老年人与年轻人一样，具备完全吸收所提供底物的能力。老年人吸收不良病例增多可能是由于其多病共存情况增加所致。
