Malassimilation should be suspected in horses with weight loss in spite of a good appetite. Malassimilation is usually confirmed with oral glucose or D-xylose absorption tests, whereas the oral lactose tolerance test can be used to evaluate lactase deficiency in foals. Once malassimilation is confirmed, other diagnostic tests such as abdominocentesis, rectal mucosal biopsy, or exploratory laparotomy with intestinal biopsies may determine the etiology of malassimilation.
尽管食欲良好，但体重减轻的马匹应怀疑有消化吸收不良。消化吸收不良通常通过口服葡萄糖或D-木糖吸收试验来确诊，而口服乳糖耐量试验可用于评估幼驹的乳糖酶缺乏情况。一旦确诊为消化吸收不良，其他诊断测试，如腹腔穿刺术、直肠黏膜活检或剖腹探查及肠道活检，可能有助于确定消化吸收不良的病因。
