First, the five major causes of bad breath 1. Dieting to lose weight leads to bad breath. Losing weight has become a word that many women often talk about. However, dieters inadvertently inhibit the secretion of saliva, leading to the growth of oral bacteria. At the same time, the consumption of body fat will also release an odorous acetone, and bad breath will follow. 2. Bad breath caused by pharyngitis Generally, women with chronic and acute pharyngitis are often accompanied by bad breath. Such people often feel dry throat, sore throat or sore throat, which can be solved by treating sore throat. 3. Bad breath caused by dryness and heat. Such people may suffer from aphtha and chronic periodontitis, or they usually like to eat spicy food with strong taste, which may cause bad breath. Stomach fire should be properly removed, and it can be eliminated by eating less hot and dry food. 4. Bad breath caused by constipation This bad breath is caused by normal defecation habits and living habits. If the harmful substances produced in the body cannot be discharged in time, they will be absorbed into the blood and cause autotoxic symptoms such as bad breath, bloating, loss of appetite and restlessness. There is no special way to get into the habit of defecation in time, drink more water and eat more vegetables. Generally speaking, breath symptoms will disappear. 5. Adolescent halitosis Women with halitosis are mainly adolescent girls, because women's ovarian function is closely related to oral mucosal epithelium. At this time, the ovarian function is underdeveloped, the level of sex hormones is low, the resistance of oral tissues will also decrease, and the oral cavity will become dry, which is easy to cause bad breath. Second, the six evils of bad breath are 1. Psychological and physiological research shows that fresh breath has a real impact on the secretion function of human hypothalamus and pituitary gland, and also has a direct impact on the nervous system. Experiments show that fresh breath can not only make people feel happy, enhance their self-confidence, but even enhance their judgment. When a day's work and life start with a fresh breath, it is hard to imagine that this person will get a satisfactory and efficient return on this day. This is also the reason why many people like chewing gum and other delicious things. It's just that all these methods have the same defect: they can only relieve bad breath at that time, but can't cure the cause. 2. Affect your appetite Although some people are not very sensitive to their bad breath, they have unconsciously affected their appetite and taste gland function. 3. The investigation of aggravating oral diseases shows that the incidence of oral diseases is at least 50 times higher in people with bad breath than in ordinary people. 4. Closely related to gastrointestinal diseases At the beginning of this century, although the medical community has not fully explored the deep causes of gastrointestinal diseases and halitosis, people have discovered the close relationship between halitosis and gastrointestinal diseases: most people with halitosis have gastrointestinal diseases. #p# Subtitle # E #e#5 .. Outpost of gastric cancer and gastroparesis Among the gastrointestinal diseases closely related to halitosis, the most serious are gastric cancer and gastroparesis. In the investigation of patients with gastric cancer and gastroparesis, it was found that the halitosis of these patients generally reached the depth standard. 6. Although the harm that seems to affect social communication has nothing to do with health, it is the most serious harm in the eyes of the people with bad breath who are investigated. In modern society, interpersonal communication is becoming a necessary means of survival. What a person can achieve in society often depends largely on his ability to communicate with others. However, bad breath seriously hinders people's communication: job hunting is rejected, colleagues are not close, neighbors don't like it, bosses don't appreciate it, subordinates dare to be angry and dare not speak, lovers "keep their distance", social occasions are cold, family life is alienated ... In communication, self-confidence and self-esteem are seriously damaged, and many psychological diseases will appear in severe cases, and even develop into autism, anxiety, phobia, obsessive-compulsive disorder, hypochondria and so on. Further development may lead to some more serious mental diseases, such as schizophrenia, affective disorder, reactive mental disorder and so on.
