Summer is the high season of gastrointestinal diseases, Chinese medicine often says “to be disease free, intestines without slag; to live a long life, intestines are always clear.” The intestinal tract is the largest micro-ecological environment in the human body, its normal or dysfunctional, has a pivotal impact on human health and life expectancy. The gastrointestinal tract is the “second brain” The gastrointestinal tract is not simply a tube composed of muscles and mucous membranes, but a whole that functions under the control of a complex nervous system. On the one hand, the gastrointestinal tract is innervated by the autonomic nervous system of the thalamus; on the other hand, the gastrointestinal tract itself has an autoregulatory nervous system, namely the intermuscular plexus and the submucosal plexus, and the total number of neurons is similar to that of the spinal cord. Recent studies have found that many peptide hormones present in the gastrointestinal tract also exist in the brain as genetic material for neural information, so called brain and intestinal peptides, which also suggests that there may be some intrinsic connection between the nervous system and the gastrointestinal system. Therefore, the gastrointestinal tract is said to be the “second brain” of the human body. Poor mood can also cause the gastrointestinal “angry I believe we all have such life experience: when the work is not smooth, nervous, and colleagues live after family quarrels, or there is a significant unexpected events, often tea and food, no appetite; angry after the epigastric pain, bloating, chest tightness, gas and other symptoms; in our daily life, we often hear In our daily life, we often hear words like “I’m full of gas”. All these indicate that mental factors are related to gastrointestinal activities. Traditional Chinese medicine also believes that the changes in human emotions can be divided into seven emotions, such as joy, anger, sadness, thought, grief, fear and fright, and the changes in the seven emotions are closely related to the functional activities of the internal organs. Emotional reactions are too strong and persistent, making the mental will difficult to bear, and when they exceed the range of physiological adaptation, they will affect the operation of qi and blood and the function of the internal organs, leading to the imbalance of yin and yang and morbidity. The seven emotions of thought and gastrointestinal tract is closely related, thought is the will of the spleen, excessive thinking, worrying about the spleen, clinical symptoms such as chest tightness and abdominal distension, food stagnation is difficult to eliminate, do not think about eating, etc., all of the above illustrate the relationship between mental factors and gastrointestinal disorders, our happiness and sadness will affect the gastrointestinal happiness and sadness, so we must adjust our emotions in a timely manner, avoid making the stomach and intestines “angry “. 6 symptoms to warn of intestinal diseases The incidence of intestinal diseases has been increasing year by year, but many people do not take it seriously and do not pay attention to intestinal diseases. Another important reason is the insidious nature of intestinal diseases, most intestinal diseases do not have obvious symptoms at the beginning, and by the time they are found to be sick, they are often already very sick. When we have the following symptoms, it is a sign of intestinal problems 1. Lack of appetite. It may be the result of a disorder of digestion and absorption or abnormal movement of the intestine. However, there are many causes of loss of appetite, which can be caused by mental factors, drug reactions or other organ diseases, in addition to gastrointestinal diseases. 2. Nausea and vomiting. This symptom is often present when there is high intestinal obstruction or abnormal intestinal motility. 3.Abdominal pain. Acute abdominal pain can occur in intestinal inflammation, intestinal obstruction, intestinal perforation, intestinal collaterals ischemia, etc. Intestinal tumors or chronic inflammatory lesions often have persistent abdominal pain. 4, diarrhea. Acute diarrhea is mostly related to intestinal bacterial infection, bacterial toxins or other harmful substances loss of intestinal mucosa. Chronic diarrhea is mostly related to various causes of absorption dysfunction, intestinal tract motility and other diseases. Chronic diarrhea due to small intestine diseases is often accompanied by malabsorption, and diarrhea due to colon diseases is mostly seen in chronic inflammation or colonic hypermobility. 5, constipation. Weakened intestinal movement, reduced muscle tone of the intestinal wall, colon and rectum due to inflammation or tumor causing narrowing of the intestinal lumen, can cause constipation. Constipation can also be caused by drugs, changes in lifestyle patterns, diet too little too fine, too little fiber content in food. So constipation is not always organic disease of the intestines. 6, gastrointestinal bleeding. According to the site of bleeding can be divided into upper gastrointestinal bleeding and lower gastrointestinal bleeding. The manifestation is vomiting blood or tarry black stool. If the vomited blood is dark red or black, it is due to the iron contained in hemoglobin turning into iron sulfide through the action of intestinal bacteria. Acute gastroenteritis is a summer disease Acute gastroenteritis is an acute inflammatory change in the mucous membrane of the gastrointestinal tract caused by eating food containing pathogenic bacteria and their toxins, or by improper diet, such as an excess of irritating food that is not easy to joke.
