Vaginal inflammatory diseases are the mainstay of gynecological outpatients, with a high incidence and recurrence that seriously affects women’s physical and mental health. Common vaginitis include Candida vaginitis (known as mycosis fungoides), bacterial vaginitis, trichomonas vaginitis, gonococcal vaginitis, senile vaginitis, and vaginitis without a clear pathogenic infection. The female vagina, like the external and internal genitalia, is a weakly acidic environment containing a variety of flora. Under normal conditions, the flora fight against each other and there are no obvious abnormal dominant bacteria, so the flora are at peace with each other and women do not feel any significant discomfort. The flora reproduce and metabolize in the vagina and are discharged in the form of leukorrhea together with shed cells, physiological secretions and discharges from the cervix and uterine cavity. When the vaginal environment is disrupted, symptoms follow. The pathogenic bacteria become the dominant flora and disrupt the vaginal environment, cellular metabolism increases, the pathogenic bacteria invade the surrounding tissues, secretions increase and are discharged to the vulva, resulting in itching. There are many reasons for disrupting the vaginal environment, such as uncontrolled sex, unclean sex, lack of attention to vulva hygiene, tight clothing, excessive douching, and other reasons for the decrease of the body’s resistance, such as staying up too late, being too tired, and disrupting the balance of the vaginal flora with the excessive use of antibiotics. Therefore, the treatment of vaginitis starts from these and other aspects as well. What doctors can usually do is to use relevant antibiotics to suppress pathogenic bacteria, increase probiotics and properly regulate the body. Many of these sufferers find that even though they take the medication as prescribed, the vaginitis still comes back again and again. It is also up to the patient to fundamentally change some of her bad habits, pay attention to vulva cleanliness, exercise properly and regulate her diet to maintain the vaginal environment. For older people, the situation is not so consistent. With the increase of age, especially after menopause, the estrogen level decreases significantly, the vaginal wall becomes thinner and more fragile, the secretion decreases and the discomfort after sex becomes more obvious. To maintain the vaginal environment, you can use appropriate lubricants before sex, do not have too frequent sex, and consume soy foods appropriately.
