The human gut hosts 10 trillion bacteria that influence weight and digestion, defend against infection and the risk of autoimmune disease, and control the body’s response to cancer treatment drugs. These vast numbers of bacteria can be broadly divided into three broad categories: beneficial, harmful and neutral bacteria. The health of the human body is closely related to the structure of the probiotic flora in the gut. The intestinal flora in the long-term evolutionary process, through individual adaptation and natural selection, between different species in the flora, between the flora and the host, between the flora, the host and the environment, always in a dynamic balance, forming a system of interdependence and mutual restraint, therefore, the human body in normal conditions, the flora structure is relatively stable, to the host performance is not pathogenic. Intestinal flora dysbiosis The intestinal flora is combined in a certain proportion, and each bacterium restrains each other, interdependent, forming an ecological balance in quality and quantity, once the internal and external environment of the body changes, especially the long-term application of broad-spectrum antibiotics, sensitive intestinal bacteria are inhibited, and the uninhibited bacteria multiply, thus causing flora dysbiosis, and its normal physiological combination is destroyed, and produce pathological combination, causing clinical symptoms. It is called intestinal flora dysbiosis. Symptoms of intestinal flora disorders The main clinical manifestation of this disorder is severe diarrhea or chronic diarrhea, or symptoms such as constipation, bad breath and poor mental health. Some travelers may have intestinal flora dysbiosis due to the change of climate and environment commonly known as hydrophobia. In recent years, due to the popular use of refrigerators, some families store a large amount of meat and sparse food, too long storage so that food deterioration, after consumption caused intestinal flora dysbiosis, resulting in vomiting, diarrhea, some appear mental inattention and even mental trance. What causes easily lead to intestinal flora dysbiosis 1, drug factors The long-term use of a large number of broad-spectrum antibiotics, while killing pathogenic bacteria, but also will kill a large number of normal beneficial bacteria in the intestinal tract, part of the antibiotic-resistant pathogenic bacteria multiply, resulting in intestinal flora dysbiosis or even dual infection, diarrhea or constipation and other symptoms. 2, diet and lifestyle habits Diet can cause significant changes in the fecal flora. Fiberless food promotes bacterial translocation. Fiber can maintain the normal metabolism and cellular dynamics of intestinal mucosa cells. Food fiber can reduce bacterial translocation, but cannot restore the barrier function to normal. Overeating, consuming too much meat, acidic food, fast food, convenience food and fried food, as well as unhealthy lifestyle, such as staying up late and irregular living can lead to intestinal flora imbalance. 3, mental factors mental stress can also lead to intestinal flora dysbiosis, excessive mental stress, will produce anxiety, depression and other emotions, resulting in dysfunction of the neuroendocrine system, intestinal physiological disorders, so that the intestinal micro-ecological environment out of balance, and often appear loss of appetite, bloating, belching, mild diarrhea, constipation or alternating diarrhea and constipation and other uncomfortable symptoms. 4, age factor As age increases, the balance of intestinal flora can be changed, bifidobacteria decreased, and the increase of aerobic bacilli, the former may weaken the stimulation of immune function, the latter leads to an increase in toxins so that immunity is suppressed. If the elderly can maintain the balance of intestinal flora when they were young, they may be able to improve immunity. 5, environmental factors Travel, tourism, field mobile work and other frequent discomfort, such as abdominal distension, diarrhea, all for the external environmental changes caused by the intestinal flora imbalance performance. Prevention 1, to reasonably apply antibiotics, because antibiotics can easily lead to intestinal flora dysbiosis and the growth of some drug-resistant bacteria will occur intestinal diseases, the elderly and frail or chronic wasting disease patients, the best in the use of antibiotics to do drug sensitivity tests, and then choose the right antibiotics. 2, in some elderly or weak patients after the disease, the use of antibiotics can be used at the same time lactobacillus or bifidobacterium to carry out treatment, so as to prevent the occurrence of dysbiosis strip. 3, the usual food should also be used fresh. Can not use the food placed too long, such food is easy to cause dysbiosis, before and after meals to pay attention to hand washing, otherwise it will also bring bacteria into the mouth will cause intestinal bacteria dysbiosis. Warm tips Intestinal flora dysbiosis is mostly caused by some diseases, once the disease to timely treatment, or diarrhea serious, it will cause shock, life-threatening.
