Summer is a time of high incidence of gynecological diseases because of the hot weather, humid climate, increased secretions and sweat, and easy breeding of germs. It is important to prevent the high incidence of gynecological diseases in summer for good female health care. The most common gynecological diseases in summer are vaginitis, cervicitis and pelvic inflammatory disease. Vaginitis accounts for about 40% of gynecological diseases in the Department of Obstetrics and Gynecology of Chengdu Women’s and Children’s Center Hospital. Vaginitis is a general term for a variety of inflammatory diseases of the vaginal mucosa caused by different etiologies. In healthy women, the vagina has a natural defense against pathogens and does not become inflamed. However, when the vagina’s natural defenses are disrupted, pathogens can easily invade and cause vaginitis. The symptoms are: increased vaginal discharge, itching of the vulva, which may be accompanied by a burning sensation and a bad smell. Inflammation of the cervix is one of the common gynecological diseases, including inflammation of the vaginal part of the cervix and the mucous membrane of the cervical canal. Since the squamous epithelium of the vaginal part of the cervix continues with the squamous epithelium of the vagina, inflammation of the vagina can cause inflammation of the vaginal part of the cervix. Since the mucosal epithelium of the cervical canal is a single layer of columnar epithelium, it has poor resistance to infection and is susceptible to infection. There are acute cervicitis and chronic cervicitis. Among them, chronic cervicitis mostly comes from untreated or incompletely treated acute cervicitis. In acute cases, the clinical manifestations are increased vaginal discharge, intermenstrual bleeding or with urinary tract infection. Causes of pelvic inflammatory disease include postpartum or post-abortion infection, postoperative infection from intrauterine surgical operations, unhygienic menstruation, direct spread of inflammation from neighboring organs, and acute attacks of chronic pelvic inflammatory disease. Pelvic inflammatory disease may manifest as lower abdominal pain and increased vaginal discharge. The abdominal pain is persistent and worsens after activity or sexual intercourse. Severe disease may present with fever or even hyperthermia, chills, headache, and lack of appetite. There may also be no obvious systemic symptoms, sometimes low fever, mental discomfort, peripheral discomfort, insomnia, lower abdominal cramps, pain and lumbosacral soreness, irregular menstruation, etc. So, how to prevent and control gynecological diseases in the summer? 1, use cotton, breathable loose underwear, underwear must be kept dry and hygienic. Change your underwear often, but also wash your underwear often, iron more, sun more. The strong ultraviolet rays in summer have a strong penetrating power and can effectively sterilize. If it is rainy and humid weather, you can use air dryers and hair dryers for drying, which is equally effective. 2, regular gynecological screening, timely detection and treatment of gynecological diseases. 3, to eliminate the indiscriminate use of antibacterial agents. Many women feel uncomfortable, will go to the pharmacy to buy some antibacterial agents, the symptoms are reduced and then stop the drug. In fact, broad-spectrum antimicrobials kill pathogenic bacteria while also inhibiting some of the beneficial flora, leading to disorders in the body’s flora and the generation of drug-resistant bacteria, which are not inhibited and foreign drug-resistant bacteria will take advantage of the opportunity to multiply, including mycobacteria, which can easily lead to “mycosis fungoides”. Therefore, women who feel uncomfortable should go to the hospital for checkups and use the medication for the cause under the guidance of a physician and in sufficient quantity. 4. Do not use medicated cleansers or lotions frequently to clean the vulva, as this may lead to disruption of the internal environment and induce inflammation. It is enough to wash the vulva with water every day. Those who are ill should use lotions under the guidance of a physician. 5. Pay attention to menstrual hygiene. Sanitary napkins should be placed in a dry, ventilated place, and need to be changed when used during menstruation, pay attention to vulvar cleanliness and hygiene, and avoid bathing and intercourse during menstruation. 6, eliminate the long-term use of non-menstrual sanitary pads. Most of the pads have a layer of plastic at the bottom, poor breathability, it is easy to cause the pubic moisture, sweating, so that the pathogenic bacteria breeding. Long-term use of sanitary pads will greatly increase local humidity and temperature, which not only creates suitable conditions for the growth of bacteria and fungi, but also destroys the pH of the vagina and reduces the local protective barrier, which can cause vaginitis. 7. Use less and try not to use unclean products. The public toilets and towels in hotels are frequently used by many people, and sexually transmitted diseases can be transmitted to others through contaminated toilet seats or towels. It has been determined that Neisseria gonorrhoeae can survive for 18 hours on toilet seats and Trichomonas vaginalis can survive for 6 hours in a semi-dry environment. When using a toilet in a public restroom or hotel, it is best to take the squatting type or try to choose a single-use seat. Try to bring your own towel. 8, put an end to unclean sexual behavior. The unclean sex is also the culprit of gynecological diseases. Trichomonas can be parasitic in the reproductive tract, including women and men, men are mainly parasitic in the male urethra, urethral bladder gland, and even the bladder. Trichomonas is a parasite that can be transmitted to women after sexual intercourse without any symptoms. Therefore, you should clean your body before and after sexual intercourse, and keep a fixed sex partner. 9. Use the correct form of contraception and reduce the mechanical stimulation of abortion or induction of labor. 10, pay attention to swimming hygiene. The prevalence of trichomonas and mycobacterial vaginitis in women increases after swimming because carriers can bring pathogens into the pool water, which can be easily transmitted to healthy swimmers. Not only the water but also the pool floor, steps and public lockers are potential sources of infection when swimming. Should avoid menstrual swimming; swimming do not sit on the ground; clothing into plastic bags and then put into lockers. Women should clean their whole body immediately after swimming and drink more water to eliminate heat and diuresis, flush out the parasitic bacteria in the urethra and eliminate the potential for infection.
