Ms. Wu, who had been suffering from paroxysmal severe cough for 14 years, had no abnormalities in her lungs after several examinations and was treated for “chronic bronchitis” without improvement. This chronic cough brought her endless troubles, not only affecting others, but also causing her to shed tears, and even develop stress urinary incontinence, and she had to quit her job and stay home. I took a careful medical history at the clinic and found that she had suffered from chronic stomach problems for many years and liked to drink thin rice for three meals a day. A retired old cadre, no matter at noon or at night, would wake up with a cough every time he went to sleep, often having trouble sleeping through the night and suffering exceptionally for more than 20 years. He also has the habit of drinking thin rice for three meals a day. Another old man, for many years, kept coughing a lot of white mucus phlegm after each meal, and it took at least half an hour to settle down, which made him suffer. Likewise, he could not live without three meals a day, and liked to eat while drinking soup. One of my classmates, who is young, often suffers from chest tightness at night, accompanied by pain in the anterior chest area and the back, and has always suspected coronary heart disease. He usually also likes to drink thin rice and eats irregularly, often gobbling it up, and each attack is related to eating too much or drinking alcohol. There are also many patients who have inexplicable panic attacks and palpitations, which worsen at night, or are afraid of cold and heat all year round, but they cannot find out the cause of these attacks, and they become “difficult and complicated”. If you pay close attention to it, it is often related to drinking thin rice. Three years ago, during my visit to the countryside in Liaocheng, I noticed a significant increase in the number of chronic cough patients here, and people here generally like to drink millet or cornmeal porridge. During the earthquake relief in Sichuan, I also found that people in the mountainous areas here commonly drank a kind of corn ballast porridge, and some of them also had chronic coughs for many years. After telling them to change their dietary habits, their coughs were significantly relieved. Of course, some people do not drink thin rice, but like to eat noodles, or are fond of groundnuts, or like sweet food, or eat while drinking water; eat while drinking soup. This is the same reason as drinking thin rice, and is not conducive to digestion. There is also a common feature is to eat fast, which can easily lead to esophageal relaxation and easy to cause food reflux. Does drinking thin rice really bring so much trouble? Most people think that a bad stomach needs to eat something soft and drink something thin so that it is easy to digest. This is just taken for granted, but the opposite is true. When the stomach is digesting food, it needs the pylorus to wrap around the food and squeeze it down a little. If it is thicker food, it is easy to wrap, and thin food is easy to flow back, causing food to flow up and down in the stomach, not easy to empty, especially the starchy corn gruel type of food. Food in the stomach for a long time, it will suffer from a variety of gastric diseases. When lying down, especially after sleeping, the cardia sphincter is relaxed and easily refluxes into the esophagus, resulting in congestion, edema and erosion of the esophageal mucosa, causing various symptoms, which is the cause of reflux esophagitis. Some people also have a relaxed sphincter of the cardia when they are standing up, but the cough and other symptoms are more pronounced. People generally think that coughing is caused by lung diseases, and they have been misdiagnosed as “chronic bronchitis”, “asthma” or “coronary heart disease” due to long-term lung-related examinations. The use of antibacterial drugs is ineffective, or various tests are repeatedly performed due to unclear diagnosis, which not only increases patients’ pain, but also increases their financial burden. In fact, coughing is not only a problem with the lungs, but also with many organs. The same reflexes are also located in the esophagus, stomach, pericardium, diaphragm and nasal cavity. As the ancients said, “All the five internal organs and six internal organs can cough, not just the lungs”. When the cough reflexes in the lining of the esophagus are stimulated by esophagitis, it can lead to a stubborn and violent cough. In addition, the filling of the esophagus squeezes the membranes of the trachea, which also causes coughing and coughing up mucus sputum. We now know that gastro-oesophageal reflux due to frequent consumption of thin meals is a more common cause of chronic cough. In the past, it was usually the middle-aged and elderly who were prone to gastro-esophageal reflux disease, but now it is also common among young people because people are now exercising less and not only the skeletal muscles are less developed, but also the internal smooth muscle of the esophagus loosens up, causing food reflux in the stomach. There are also some people who take antihypertensive drugs, some of which work by relieving smooth muscle tension, which inadvertently makes the smooth muscle of the esophagus loose. Knowing the causes, we have to take measures for the symptoms. First of all, we should change our eating habits, try to eat hard food, such as baklava, steamed bread, rice, etc. Do not eat noodles, dumplings, wontons, rice noodles, etc. Thicker food is not easy to reflux. Eat in a happy mood, chew slowly, not quickly. Because the stomach does not secrete amylase, and amylase is only found in saliva, if you swallow without chewing, there is one less procedure. Eat meals with less water, soup and porridge, or even no drink. Drink water one to two hours after a meal, so that water and rice are absorbed separately. Avoid oversaturated bedtime before eating, to go to sleep on an empty stomach. Avoid eating acidic, greasy food and drinks, lie on a high pillow and elevate the head of the bed. At the same time, you can take gastric motivation drugs and antacids, but they are only auxiliary means, the main thing is to eat scientifically. Some people have stomach problems caused by Helicobacter pylori and need to be treated with a standardized triple drug regimen. In some cases, due to long-term coughing, irreversible damage to the epithelial mucosa of the trachea is formed, which should be treated in the hospital in a standardized manner. Of course, before treatment, it is advisable to perform a chest examination to exclude the possibility of inflammation in the lungs, tuberculosis, tumors or chronic heart failure.
