摘要：曾听过有句俗话“穷人不聚财，饭饱stool出来”。其实在医学领域，有专门的术语称之为“胃结肠反射”，是一种人体进食后的身体反应，导致这一反应有个人的体质差异的原因，也有其他如食物刺激、情绪等原因，跟人的贫富啥关系都扯不上。
What Causes People to Poop Right After Eating?
The most likely cause of needing to poop right after eating is the gastrocolic reflex. This reflex is a normal involuntary reaction to food entering the stomach. It does not mean food is passing straight through the body.
进食后需要立即排便的最可能原因是胃结肠反射。这种反射是食物进入胃时的一种正常的不自觉的反应。这并不意味着食物会直接通过体内（直接排出）。
The gastrocolic reflex, or gastrocolic response, is a normal involuntary reaction to food entering the stomach.
胃结肠反射，或称胃结肠反应，是食物进入胃后的一种正常不自主的反应。
When food enters this organ, the body releases a hormone that causes the colon to contract. These contractions move previously eaten food further through the digestive system, which can result in the urge to pass stool.
当食物进入胃时，身体会释放一种激素，导致结肠收缩。这种收缩使以前吃过的食物通过消化系统，从而导致排便的冲动。
For some people, the gastrocolic reflex is mild, causing no symptoms. For others, the reflex is intense, and the urge to poop after eating can be particularly strong.
对一些人来说，胃结肠反射很轻微，没有任何症状。对另一些人来说，反应是强烈的，吃完后想上大号的冲动可能特别强烈。
Certain health conditions can affect the gastrocolic reflex. For example, irritable bowel syndrome (IBS) can cause a person's digestive tract to move food through their system much faster. Other conditions that could cause a person to pass stool more quickly than average include: food allergies and food intolerances, anxiety, gastritis, celiac disease and so on.
某些健康状况会影响胃结肠反射。例如，肠易激综合征(IBS)会导致一个人的消化道更快地将食物通过消化系统。其他可能导致一个人比平均速度更快地排便的情况包括：食物过敏和食物不耐受、焦虑、胃炎、Ru糜泻等。
The conditions above may increase the intensity of the gastrocolic reflex, resulting in an urge to poop soon after eating. The gastrocolic reflex is a normal reaction to food entering the stomach.
上述情况可能会增加胃结肠反射的强度，导致进食后不久就想大号。胃结肠反射是食物进入胃后的正常反应。
In most cases, feeling the urge to poop after eating does not warrant a visit to the doctor. However, a person should see a doctor if they experience the intense and frequent gastrocolic responses to food, diarrhea lasting longer than 2 days, and additional gastric symptoms.
在大多数情况下，进食后想上大号的冲动并不需要去看医生。然而，如果一个人对食物有强烈和频繁的胃结肠反应，腹泻持续时间超过2天，以及其他胃部症状，则应该去看医生。
Some foods are more likely than others to cause an intense gastrocolic response like fatty or greasy foods, dairy products, and foods high in fiber. Once a person identifies a possible trigger food, they should temporarily avoid it to see whether their symptoms improve.
有些食物比其他食物更容易引起强烈的胃结肠反应，比如脂肪多或油腻的食物、乳制品和高纤维食物。一旦一个人确定了可能的触发胃结肠反应的食物，他们应该暂时避免食用此类食物，看看症状是否有所改善。
For some people, stress can increase the intensity of the gastrocolic reflex. These individuals may benefit from activities that help reduce stress. Examples include exercise and meditation.
对一些人来说，压力会增加胃结肠反射的强度。这些人可能会从有助于减轻压力的活动中受益，包括锻炼和冥想。
