Bacterial vaginosis is somewhat related to the use of condoms. Using condoms for contraception can, to some extent, prevent bacterial vaginosis because it is caused by the disruption of the vaginal microecological balance, resulting in an increased vaginal pH and a mixed infection. The entry of semen into the female body can raise the vaginal pH and disrupt the vaginal microecological balance, thus making bacterial vaginosis more likely to occur. However, when a condom is used, semen does not enter the vagina, which means that it does not alter the vaginal pH balance. Therefore, to a certain extent, it can prevent bacterial vaginosis and also protect against some sexually transmitted diseases. Bacterial vaginosis can lead to an increase in vaginal discharge, and the discharge may have a characteristic fishy odor, which can cause endometritis and pelvic inflammatory disease. Thus, using condoms for contraception can, to a certain extent, prevent bacterial vaginosis.

How many days does a fever last in bacterial pneumonia?

Bacterial pneumonia can cause sudden high fever and convulsions. Typically, the fever lasts about three to five days. In patients with weak immunity, the fever may persist for seven to ten days. Decisions should be made based on the amount of bacteria in the body and the immune capacity. It's important to adjust your mindset, understand correctly, and seek early detection and treatment. Maintaining appropriate indoor temperature and humidity is crucial. When feverish, it's necessary to measure body temperature. If it does not exceed 38 degrees Celsius, oral antipyretic medications generally aren't necessary; physical methods to reduce fever can be used to relieve discomfort.

The main treatment methods for vaginitis

The primary treatment for vaginitis involves the use of local vaginal medications to improve the vaginal environment. Some cases also require oral medication for systemic treatment, but the crucial factor is identifying the type of vaginitis. For example, bacterial vaginitis can be treated primarily through oral medications, but local vaginal treatment is also an option. Yeast infections primarily involve local treatment with vaginal medications to alleviate symptoms. If there is no sexual activity and vaginal medication is unsuitable, oral medication can be used for systemic treatment. Trichomoniasis is mainly treated with oral medication for systemic treatment and should not be treated with local vaginal medications. Some types of vaginitis in elderly women can also be treated with local applications of estrogen cream or oral medication to supplement systemic estrogen therapy. Therefore, the main treatment methods for vaginitis depend on the specific type of infection.

How to treat pain during urination caused by bacterial vaginitis?

Bacterial vaginitis refers to when the pathogen in the vagina is Gardnerella and is associated with a disruption of the vaginal flora. This can result in an increased amount of discharge, with a foul odor. An increased amount of vaginal discharge can irritate the vulva, leading to severe vulvitis, and possibly cause pain during urination. If pain during urination is accompanied by urinary urgency and frequency, it should be considered that there might be a urinary tract infection, and a urinalysis could be conducted. If a urinary tract infection is confirmed, it is necessary to drink more water, urinate more frequently, and take oral levofloxacin. If tests confirm that there is no urinary tract infection and the symptoms are only due to local irritation, using a 1:5000 potassium permanganate sitz bath daily for 15 minutes can significantly alleviate the pain during urination. Additionally, systemic medication should be administered to treat bacterial vaginitis. Only after the vaginitis is cured, which would significantly reduce the discharge, can the vulvitis and pain during urination be relieved. (Medication should be administered under the guidance of a physician.)

Does bacterial vaginitis have any relation to cervical cancer?

Bacterial vaginosis is not closely related to cervical cancer. Bacterial vaginosis is caused by an imbalance of vaginal flora, leading to an increase in vaginal discharge, which can have a fishy odor and be thin and watery. This condition can be diagnosed through routine vaginal discharge tests. Subsequent treatment, under a doctor’s guidance, may include the oral administration of metronidazole. During treatment, it is advised to avoid sexual intercourse to prevent impacting the effectiveness of the treatment. The development of cervical cancer is mostly related to prolonged infection with high-risk HPV viruses, or factors such as early sexual activity, multiple sexual partners, and unhygienic sexual practices. Generally, it is not significantly related to the presence of vaginal inflammation. (Please follow medical advice when using medication.)

Why does bacterial vaginitis turn into fungal vaginitis?

Women with bacterial vaginitis need to be treated with metronidazole, which can be either taken orally or applied as metronidazole vaginal effervescent tablets. Some women may experience recurrent bacterial vaginitis, which leads to a longer duration of medication use, potentially causing an imbalance in the vaginal flora. Yeast naturally exists in the vagina, but the environment is usually stable due to the predominance of lactobacillus, which inhibits the growth of yeast. However, if the treatment period for vaginitis is extended, it can disrupt the vaginal environment, reduce the amount of lactobacillus, and consequently, yeast can proliferate and lead to yeast-based vaginitis.
