Truth, can constipation cause colorectal cancer?

Is what constipated?

To manage and control your constipation, First of all, it should be clear that what is constipated. But I’m afraid even this is not really clear to many friends. For example, it is constipation to think that one cannot defecate once a day. In fact, [Constipation] There is actually no uniform standard, But because of personal constitution and other factors. Generally speaking, constipation is only considered once in 3 or 4 days. However, it should be noted that, Even if you defecate once every 2 days, If you feel difficult to defecate, stool is hard and your abdomen is stuffy, It’s also constipation. Constipation is not a disease, It’s really disturbing to be secretive. Constipation is not what’s secret. Not even [disease]-constipation is essentially a [common symptom] that can be caused by multiple complex factors alone or jointly. Just like fever and cough-but it can make you feel all kinds of indescribable depression: when others come out of the bathroom for 3 to 5 minutes, it’s your turn to still be there after a quarter of an hour, trying hard for luck, panting and flushing cheeks; Or stool induration, once too hard, maybe send you a [chrysanthemum full hip injury]; I often feel that I can’t pull it clean, and I’m always not satisfied. There are many habitual constipation patients who feel abdominal distension such as bulging and stuffy pain and discomfort over the years. If it is just to annoy the body, Constipation is not that bad, But constipation can also cause heart disease: People who suffer from constipation for a long time may suffer from mental and psychological disorders such as depression, anxiety and insomnia. Another kind of torture is the topic that will be discussed below-worry that constipation will lead to a serious health and life-threatening disease: [Colorectal Cancer]. The Legend of Constipation and Colorectal Cancer the so-called legendary person, As the name implies, it is a kind of saying that has been passed down for a long time. And has considerable influence in a wide range of people, for example, the legend that [constipation can lead to colorectal cancer] is believed to be heard by most people. Some neurotic constipation patients will be compulsive to think about it, scared all day long, and always feel, [finished, I have been constipated for so long, I will definitely get colorectal cancer in the future! ] So what logic does constipation lead to colorectal cancer? There are several statements, But the most popular is: [Constipation] = [Stool staying in large intestine for a long time], Therefore, carcinogenic substances contained in stool have the opportunity to contact the large intestine wall (large intestine mucosa) for a long time. After a long time, it induces canceration. At the same time, the dry and hard feces themselves are rubbing against the mucosa of the large intestine, which is also a harmful mechanical physical stimulation. It is easy to cause intestinal injury, inflammation and eventually pointing to cancer. How do you feel after reading the above passage, it seems quite reasonable, right? Yes, this kind of legend is extremely marketable: Not only in China (today’s Chinese medical textbooks still have descriptions of constipation causing colorectal cancer), Even Japan, the eastern neighbor of a major medical country, and even developed countries in Europe and the United States have a wide range of followers. However, Legend is not the truth. Any medical viewpoint must obtain evidence through research to stand up. Look at the latest description of what as a [risk factor for colorectal cancer] by major authoritative medical institutions in the world. Gradually, you may feel something is wrong. For example, the risk factors for colorectal cancer listed by the American Cancer Society, an authoritative organization in the field of cancer, include: Like many other cancers: Age. Over 50 years old accounts for more than 90% of the total number of colorectal cancer patients. Intestinal polyps (but not all intestinal polyps can lead to colorectal cancer). Certain inflammatory bowel diseases (IBD). IBD is a general term for a large group of inflammatory bowel diseases. Closely associated with colorectal cancer are the well-known disease known as Crohn’s disease. Typical symptoms include abdominal pain, diarrhea, intestinal obstruction, Recurrent attacks, difficult to cure) and [chronic ulcerative colitis] etc. Genetic factors are medically called [family history]. Lifestyle: smoking, drinking, eating too much red meat, lack of dietary fiber, obesity, lack of exercise, etc. Some people do not account for all the above risk factors. Why do they still have colorectal cancer? I’m sorry: modern medicine is not clear. Huh? [Constipation] Is it not among the above risk factors? Is it because the editors of these authoritative organizations in the public media were careless and forgot to write it down? Of course not. There is only one reason constipation does not appear on the list of risk factors for colorectal cancer: Today, when modern medicine is becoming more and more precise and rigorous, There is no definite evidence that there is a causal relationship between [constipation] and colorectal cancer. A large study in Japan reveals the fact that at this point, It is necessary to introduce a large-scale Japanese study published at the end of 2006. The study, initiated by Japan’s National Cancer Center of Japan’s Ministry of Health, Labor and Welfare, aims to understand the relationship between constipation and colorectal cancer. The purpose of the study is to understand [constipation leads to accumulation of endotoxin in large intestine, Is the legend that it is easy to cause colorectal cancer the truth? Between 1993 and 1994, The research team asked people between the ages of 40 and 69 across Japan (regardless of gender) for details such as the number of defecations per day and the condition of daily defecation. A total of 58,000 responses were received. Based on the questionnaire, the research team continued to follow up until the end of 2001. A total of 479 people were diagnosed with colorectal cancer during this period. After comparing the information obtained successively, it was found that: [There was no statistical difference in the risk of colorectal cancer between people who defecated 2 to 3 times a week and those who defecated once or more a day]. Moreover, Even if the cancer site of colorectal cancer is divided into colon and rectum for differential examination, no difference is found. Conclusion: [There is no causal relationship between constipation and colorectal cancer]. Medical intuition is often unreliable. So why do so many people (even perhaps most people) still think constipation is closely related to colorectal cancer? It is very simple: this is because the popular saying about [the reason why constipation leads to colorectal cancer] is not only very easy to understand, but also very consistent with people’s intuition and does not require any basic medical literacy-[yes, if stool stays in your intestines for a long time, don’t you think the fart released is very smelly? The stool is rotten and fermented in your stomach. How can it not cause cancer? [Most people should have no resistance to this view, Because as long as they think of the unpleasant image and smell peculiar to stool, Will surrender immediately, Accept this echo view. For his large intestine, Don’t be fooled by intuition, Think of it as too weak: In fact, Intestines are originally used to hold excrement. Stool consists of food residue, bile and intestinal flora. Whether your gut is moving frequently or not, These things always exist in the intestines. Wrong medical views are often used by commercial advertisements. However, The speaker had no intention, The listener has a heart. Smart commercial advertisements are best at using all kinds of unfounded medical opinions circulated among the people to seek benefits. However, constipation is often reduced to the hardest hit area due to the huge population base-as long as all kinds of legends are sublimated, To create a terrorist effect of [something will happen if you don’t deal with it quickly]: This is a typical case of advertising that sublimates constipation to sojourn and then makes a lot of threats for profit. Constipation still needs to be solved. Some constipation friends are relieved to read this: finally they don’t have to worry about colorectal cancer every day because of constipation, so they clap their thighs: they can rest easy from now on! Please don’t get too proud, There is no causal relationship between colorectal cancer and constipation, doesn’t mean constipation can be ignored. On the contrary, Constipation must be dealt with seriously. This is because: 1. Constipation can lead to many other diseases. A researcher named Tetsuya Otani in the above-mentioned large-scale Japanese study also mentioned in particular: [If the average person defecates two or three times a week, There is no need to worry about colorectal cancer. However, if you defecate only once a week, Or should we seek medical treatment as soon as possible, Because constipation can also lead to many other diseases.] 2. Constipation, Sometimes it is reminding you that there may be something wrong with the diet ratio. For example, you may have eaten too little vegetables recently. And too much red meat. This kind of eating habit is easy to cause constipation, As mentioned earlier: A diet with too much red meat and too little fiber is an important risk factor for colorectal cancer. Therefore, You don’t have to worry too much about the relationship between stool frequency and colorectal cancer. But you should carefully adjust your diet. 3. Constipation is sometimes a sign of serious diseases, such as colorectal cancer, which can sometimes cause constipation. If you usually defecate once a day, Recently, I suddenly noticed a change in defecation habits. Becomes twice a week, And you’re over 50, Then you should be especially vigilant. 4. Constipation itself is uncomfortable, May affect your mental outlook. In the medical field, People’s intuition is often unreliable. Sometimes, it even runs counter to it: look at how many young children in China are covered to death by their parents and quilts every year because of fever, and you will probably understand. Don’t be fooled by intuition about your large intestine. Constipation has no causal relationship with colorectal cancer. Photo source:
