布里斯托大便分類法

布里斯托大便分類法（Bristol Stool Scale）是一種為了醫學需求而設計的分類法，它將人類的大便分為七類。^[1]^[2]^[3]設計者為布里斯托大學（University of Bristol）的希頓（Heaton）和路易斯（Lewis），首篇於1997年發表在《北歐腸胃病學雜誌》（Scandinavian Journal of Gastroenterology）上。因為大便的形狀和其待在大腸內的時間有關，所以可以用它來判斷食物經過大腸所需的時間。

分類法：^[4]

第一型：一顆顆硬球（很難通過）
第二型：香腸狀，但表面凹凸
第三型：香腸狀，但表面有裂痕
第四型：像香腸或蛇一樣，且表面很光滑
第五型：斷邊光滑的柔軟塊狀（容易通過）
第六型：粗邊蓬鬆塊，糊狀大便
第七型：水狀，無固體塊（完全液體）

第一型和第二型表示有便秘；第三型和第四型是理想的便形，尤其第四型是最容易排便的形狀；第五至第七型則有腹瀉的可能。^[5]
