Lin (chief physician of colorectal surgery, Peking Union Medical College Hospital) is far away from constipation, and the stool discharged from the intestine is black or brown. The biggest reason is the intake of meat and high-fat food. However, if the stool is darker than usual or purple, you must pay special attention to it, which may be stomach or intestinal bleeding. Xiao Jiang spread out his hands: "There's a lot of learning here, Dr. Lin. Is there a color requirement for healthy stools? " ""Generally speaking, yellow like baby shit is the most ideal. People's stools are yellow in infancy, and many turn black or brown when they grow up. " "Because everyone is contaminated with the secular taste, it becomes less pure, and even the color of the stool has changed." Jiang joked that not everyone is like this. With the increase of age, stool does not necessarily turn black. The stool discharged is black or brown, the biggest reason is the intake of meat and fatty food, which is caused by the eating habits in Europe and America. This has nothing to do with purity. ""Dr. Lin, who can always have a yellow stool like a baby? " I'm curious to ask haha, maybe it's Zen monk's shit. Why are their stools different in color from ordinary people? This is because of their eating habits. They eat vegetarian food every day and don't eat meat at all, so their stools are yellow. ""Although I really want to excrete healthy shit, I can't become a monk just to pull out beautiful shit. Eat vegetarian food at most in the future. I haven't rolled the world of mortals yet ... "Jiang said. Xiaole frowned and asked, "Dr. Lin, my stool is black. What's wrong with it?" "Black may be a serious illness. Although black or brown stool is a warning, you don't have to be too flustered. But if the stool is darker than usual or purple, you should pay special attention. This is not only that the pH value is acidic, but also that there may be gastric or intestinal bleeding. In this case, the blood is mixed with the stool, and the color changes from red to black before it is excreted. You must see a doctor at once. " "Dr. Lin, please tell me more. "There are various types of black stool. For example, the discharge of tar-like stool may be caused by diseases such as gastric ulcer, duodenal ulcer or gastric cancer. Some people excrete almost no ingredients of ordinary stool, but a mixture of blood and mucus, which is called bloody stool. This kind of stool is sometimes accompanied by severe abdominal pain or vomiting, which may be intussusception, volvulus, intestinal obstruction and other diseases. If blood in the stool is mixed with pus for several days, it is most likely colorectal cancer. If people with constipation pull out dark hard stools, it may also be a sign of colorectal cancer. This is because there is bleeding somewhere in the large intestine, which has accumulated in the intestine for a long time and turned black. Some people start with diarrhea, and soon they have bloody stools and go to the toilet frequently. This may be dysentery, sometimes accompanied by lower abdominal pain or fever. In short, I feel something is wrong, so I must see a doctor in time.

In short, I feel something is wrong, so I must see a doctor in time. Xiaole breathed a sigh of relief: "Fortunately, I am just constipated, but I will pay attention to it later. Developing good eating habits and defecating healthily is my biggest goal recently! What food is the most enjoyable? " In fact, there are many common foods in life that have laxative effects, such as cooked bananas, which are rich in dietary fiber and have a good laxative effect; Sweet potato, namely sweet potato, is sweet and warm, can strengthen the stomach and benefit qi, contains more dietary fiber, can absorb water in the intestine to increase the volume of feces, and has a laxative effect; Brown rice is rich in protein, starch, vitamins, dietary fiber, calcium, iron and phosphorus, among which rich dietary fiber is helpful for defecation. There is also the most common apple, which is rich in water-soluble dietary fiber-pectin. Pectin can protect intestinal wall, activate beneficial bacteria in intestine and regulate gastrointestinal function, so it can effectively clean intestine and prevent constipation. "Also, I know a lot of food for constipation," Xiao Jiang suddenly volunteered. "In addition to what Dr. Lin said, there are grapefruit and walnuts. Walnut kernel contains fat, protein, phosphorus, iron, riboflavin (according to vitamin B2) and so on. Besides relaxing bowels, it also has the functions of tonifying kidney, fixing essence, warming lung and relieving asthma, and can be used to treat cough due to kidney deficiency, soreness of waist and soft feet, impotence and nocturnal emission, frequent urination, dry stool, etc. Long-term use has better curative effect and no side effects. Old people with constipation may wish to give it a try. " I listened and said, "A wise head makes a close mouth! Jiang, I didn't expect you to know so much. Not only professional and detailed, but also fluent! Xiaole quickly said, "Dr. Lin, don't praise him in a hurry." Xiao Jiang is not a professional. He sells health food at best. He knows all the marketing words that specifically attract the elderly to buy health food. " "Ha ha ha." The two of us burst out laughing, and Jiang scratched his head embarrassedly. The rain outside the window has stopped. I think it's time for me to say some concluding remarks so that these two young people who have to catch a plane tomorrow can go to bed early. No matter what kind of constipation, there are always the following reasons: First, normal defecation is neglected, the habit of regular defecation is not formed, and the defecation reflex is suppressed, leading to long-term constipation; Secondly, the diet is too delicate and less slag, lacking dietary fiber, which makes the stool smaller, the viscosity increases, the intestinal movement is slow, and the water is absorbed too much, leading to constipation. There is also insufficient intake of liquid itself, less drinking water, and most of the water is absorbed by the intestine, resulting in dry stool, difficulty in defecation and constipation. In addition, the feces move forward in the intestine by the peristalsis of the intestine, rather than being inactive and obese, especially those who are bedridden or in wheelchairs due to illness, and lack the mobility to promote the movement of feces, resulting in constipation. From the crowd, white-collar workers, students, teachers and other people are prone to constipation. Because of long-term mental stress and stress, eating greasy and indigestible meat is the most prone to constipation. Therefore, constipation patients should not only develop good eating habits, but also exercise more. Xiao Jiang looked at the rainy night and said, "Work is really troublesome. Listen to Dr. Lin's lecture on sports. I haven't played basketball for a long time! Xiaole thanked politely: "Thank you, Dr. Lin. Although you are very busy, you must answer our questions. " "You're welcome. I suggest that when you can't stand it, you must go to the hospital to see a doctor. Constipation is not formed in a day or two, nor can it be recovered overnight. Good living habits are the most effective weapon against constipation, and persistence is the most difficult. I wish you a speedy recovery. " At this time, the chef personally served a plate of spinning bananas and said with a smile, "You must be tired after talking for so long. This is dessert. Dr. Lin, I heard that sweets can make people happy and bananas can relieve constipation, right? I smiled and nodded. You eat. There are two new tables in the restaurant. I'm busy in the kitchen. Xiaole pushed the spun banana in front of me: "Dr. Lin, eat it while it is hot, so as not to be hungry at night." I don't think you ate much just now. I didn't expect you to be strong and have a small appetite. In fact, he doesn't know, because it has been raining these days and there is no chance to exercise. I just want to say that eating less every night can still achieve the goal of losing weight. But I really didn't have enough to eat just now, and then I ate a few pieces of banana shreds with very high sugar content in moderation. It seems that dieting to lose weight is a pit and I will never go on a diet again. "Bedroom" does not exist? While eating, Xiao Jiang suddenly asked me a question: "Dr. Lin, do you think there is a stool?" I thought about it and said, "At present, there is no concept of defecation in medicine, and defecation is neither a medical definition nor a clinical manifestation, nor a disease. It represents a meaning more like "constipation", or the concept of "constipation" has been over-expanded. Ginger clapped her hands and said, "I tell you, there is no such thing as defecation." My stupid boss insisted that I add the words "clearing the intestines and detoxifying" to the propaganda copy. Isn't this a lie? I can't do such a business. The consumer groups of our products are women aged 20 to 40, people with chronic constipation and obesity, and young and energetic healthy people. I don't want to harm people. It turns out that Xiao Jiang works in a health food company. This year, their company developed two kinds of healthy drinks. One is a fruit enzyme known as detoxification and weight loss, and the other is a new concept weight loss tea, which is going to be listed at the end of the year and hopes to be sold through the excitement of the Spring Festival. Xiaojiang is constipated and often has loose bowels. He thinks that "poop" doesn't exist at all, so he didn't write it according to the boss's instructions, but wrote a pertinent marketing plan in detail according to the characteristics of the product, which was neither exaggerated nor conservative, and the result was rejected.
