The pelvic floor muscles are a group of muscles that enclose the pelvic floor and undertake the important functions of support, sphincter, and sex. Due to pregnancy and childbirth, aging, pelvic surgery, obesity, long-term constipation, chronic cough, etc. can cause relaxation of the pelvic floor muscles, which can lead to a series of pelvic floor dysfunctional diseases, such as stress urinary incontinence, pelvic organ prolapse, lack of sexual pleasure, menopausal genitourinary tract syndrome, etc. In case of pelvic floor disorders or sexual disharmony, the first step is to consult the gynecology department of a regular hospital (many hospitals have special pelvic floor clinics) and undergo a systematic and standardized examination, especially to receive an assessment of pelvic floor function before individualized treatment. For mild to moderate cases, non-surgical treatments such as kegel training, pelvic floor rehabilitation, and intimate laser treatment are available; for severe cases, surgery is usually required, and non-surgical treatments are only used as adjunctive treatments. For the inevitable occurrence of pelvic floor muscle laxity with age, it is recommended that prevention should be the main focus, and adult women should make kegel exercise a lifelong necessity, and not wait for the disease to become serious before paying attention to it.
