怎样算是便秘?据香港卫生署资料,便秘通常指排便习惯改变,包括:
- 排便变得不频繁,每周少于3次
- 粪便太硬、粪便太小
- 很难排便
便秘成因方面,主要有3大因素,包括:不良的饮食习惯,例如饮水不足或食物中缺乏纤维质;或又或是由一些药物的副作用引发;由一些消化系统疾病或全身性的疾病引发,例如糖尿病及甲状腺功能减退。
每天只吃一餐易便秘?只吃液体食物易便秘?
为何减肥也会导致便秘?赖医生询问该女子的饮食习惯后发现,对方表示为了避免变胖,刻意减少食量,每天只会吃一餐,而且只会喝高蛋白饮品,完全没有进食固体食物。
赖医生解释,液体蛋白质进入人体后容易被吸收,残存的固体食物也很少,加上该女子没有吃固体食物,导致粪便量不足,造成排便困难。
赖依伶医生提醒,如果受便秘困扰,应该先检视自己进食的食物份量是否足够。若只吃很少食物,食物量不足,自然会增加排便的难度。她建议便秘人士要增加进食份量,而且不能只吃液体食物,要有固体成分。另外,进行适当运动也能促进肠胃蠕动,帮助维持正常排便。

每3日排便一次是便秘吗?如何分辨便秘症状?
要分辨是否便秘,不只是看排便次数?外科医生钟云霓曾发文指,很多人以为排便频率较少就等于便秘,但其实这不是排便的唯一定义。她解释,若坐上马桶后,5至7分钟内成功排完粪便的话,并不算是便秘。不过,若每次也超过7分钟才能排便,甚至要用力挤压才能排出粪便的话,则代表有便秘问题。
