The appearance of leukorrhea in women is a normal physiological phenomenon, and leukorrhea is vaginal secretions. Normal leukorrhea usually appears as white, cool, egg-white-like or milky-white mucus, which is an odorless secretion discharged through the vagina in women without organic lesions and without conscious symptoms. The vaginal opening is often closed by the front and back walls due to the influence of the pelvic floor muscles. The moisture in leukorrhea helps to moisten the vagina and reduce the friction between the front and back walls of the vagina, which has a protective effect on the vaginal walls. It also helps to maintain the elasticity of the vagina and improve the quality of sex life. When a woman is in a special period, her leukorrhea may change physiologically with her own estrogen, which is normal and requires no special treatment. For example, when a woman is not on her period, her leucorrhea may be less, white and pasty; during special periods such as ovulation, the leucorrhea may become transparent, increased or sticky due to the secretion of the cervical glands; before and after menstruation, the leucorrhea may increase due to pelvic congestion, resulting in easy production of vaginal discharge. In addition, some women may have abnormal leucorrhea, accompanied by itching and other uncomfortable symptoms, suggesting that the female patient may have certain diseases. Abnormal leucorrhea is usually associated with many factors, such as inadequate local cleaning and reproductive system diseases. If the leukorrhea has an abnormal color, irritating odor, and becomes foamy, tofu-like or cheese-like in nature, it is a sign of abnormality and usually indicates local infection or inflammation. When abnormal leucorrhea occurs, it is recommended to actively go to the hospital for examination and targeted treatment. Women should pay attention to keep their local area clean and dry in daily life, do a good job of keeping warm, choose soft and comfortable inner clothing, etc. to try to avoid the occurrence of leucorrhea abnormalities.
