Why is squatting the most helpful posture for gastrointestinal surgery? Is there a scientific basis?

There are mainly the following points about crouching pit as a posture that is helpful for gastrointestinal operation. 1. When squatting, defecation is really smoother. From the anatomical structure of the human body, it seems that the puborectal muscle will clamp the neck of the rectum and prevent feces from being discharged without defecation. When squatting, the puborectalis muscle is completely relaxed, and the angle between anus and rectum is close to 65438+080, which means that anus and rectum are close to a straight line. When the stool comes to the rectum, it can smoothly come to the anus.

When defecating, the angle between anus and rectum is relatively small, that is to say, the hand holding the neck is not completely loosened, and the stool has to "turn a corner" to reach the anus after reaching the rectum.

In contrast, it is true that when squatting, feces can easily enter the anus from the rectum and then be excreted. In 2003, a study compared the defecation effects of squatting toilets, slightly lower toilets and normal toilets, and found that squatting toilets took less time and defecation was easier. When most people change from squatting to squatting, the defecation time is reduced.

2. Is it wrong to sit and poop?

Although squatting defecates more smoothly, it is also exaggerated to say that squatting is easy to constipation and hemorrhoids. There are many factors leading to constipation and hemorrhoids, including age, living habits, special diseases and so on. This pot can't be backed by defecation posture. Although the neck of the rectum will still be caught when sitting, it only slightly prolongs the defecation time. As long as the defecation time is not too long (less playing mobile phones), there will be no such harm. In addition, if you are really constipated, squatting can't solve the essential problem. At the doctor's suggestion, taking some safe laxatives, such as lactulose, which can be used by pregnant women and children, is much more useful than changing defecation posture. In addition, increasing vegetable intake, drinking more water, exercising moderately, developing the good habit of regular defecation, concentrating defecation and relaxing anus also have certain effects. So there's still no advantage in sitting and shitting? Wrong, sitting and pooping is more comfortable than squatting, and it is not easy to numb. Abdominal pressure increases when squatting, and postural hypotension easily occurs when standing up quickly, which may lead to cardiovascular and cerebrovascular diseases. For children, pregnant women or the elderly with insufficient muscle strength and stiff joints, sitting on the toilet is relatively safer, which can effectively avoid accidents such as falling and being unable to stand.

Best posture

It sounds like sitting and squatting have their own advantages, but they are not perfect! What is the perfect way to poop? Although "squatting side" and "sitting side" do not give in to each other and love each other, some new defecation postures between squatting and sitting are becoming popular. For example, putting a small stool in front of the toilet, stepping on the stool with your feet, and leaning forward slightly when defecating, is said to have both the smoothness of squatting and the comfort and fashion of sitting. Unfortunately, there is no exact data to prove its use. There are also some new poop postures that are extremely eye-catching, such as these wonderful poop postures compiled by a Japanese website: even some poop postures, without martial arts yoga fitness skills, can't even think about it. In fact, just like the sweet or salty taste of tofu brain, the difference of defecation posture has little effect on daily life. If you want to "pull health", posture is not important, and controlling defecation time is king. Is the posture of defecation better to sit or squat? Remember eight words: Sit if you want, and squat if you want.

It can be seen that squatting does have the benefits of squatting, but sitting is not bad. Which one to choose depends on your personal preference.
