Cervicitis is usually caused by retrograde infection of pathogens from the vagina. Severe cervicitis is more serious and is usually accompanied by such uncomfortable symptoms as abnormal leucorrhea, lower abdominal cramps, irregular vaginal bleeding and high fever. In addition, some patients may also have combined urinary tract infections, resulting in frequent urination, urinary urgency, and painful urination, which require timely treatment and may lead to serious consequences such as pelvic inflammatory disease, pelvic abscesses, and difficulty getting pregnant if the disease continues to progress. The diagnosis of cervicitis needs to be made carefully, as “severe cervical erosion” and “cervical retention cyst” are not the same as cervicitis, both of which are likely to be physiological changes. The diagnosis of severe cervicitis must be combined with the patient’s symptoms and signs and test results. If cervicitis is suspected, the patient should go to a regular hospital for gynecological examination, cervical tube endocrine smear and other related tests to confirm the diagnosis and provide targeted treatment. Since most cervicitis is caused by pathogens, cervicitis is mainly treated with antibiotic drugs. During the treatment period, patients should pay attention to personal hygiene, change underwear regularly, and wash the vulva with warm water in the morning and evening to avoid bacterial growth. In addition, patients should try to avoid public pools, bathhouses, hot spring pools and other places to avoid aggravating the disease.
