I am a girl this year 14, and my underwear is often dirty. What is the reason?

When a woman enters puberty, her lower body is always wet and her underwear is no longer clean. It is either transparent and colorless secretion, or milky white secretion like cheese, and sometimes it is slightly yellow, bloody and brown. Although there is no smell at ordinary times, if she doesn't wash her vulva and change her underwear every other day or two, the smell will be terrible. This is the influence of a large amount of estrogen secreted after ovarian development, which is called leucorrhea in medicine.

The reason why women's underwear can't be washed clean-leucorrhea

Composition of leucorrhea: the secretion of vaginal epithelium is the main substance to keep vagina moist; The secretion of cervical glands and endometrium is small, and their properties change with different stages of menstrual cycle; Vaginal epithelial exfoliated cells and leukocytes; Secretion of sebaceous glands of labia minora; Secretions of vestibular glands, etc.

Secretion of leucorrhea: Generally speaking, leucorrhea is tasteless and small, which varies with people at different stages of menstrual cycle. For example, when ovulating, the glandular cells in the cervix and endometrium secrete vigorously, so leucorrhea increases, much like thin and transparent egg white. When pulling cervical mucus with two fingers, it can be stretched to several centimeters continuously, and the elasticity is quite good. If it is in the second half of menstruation, this phenomenon will not be observed. 2-3 days before and after menstruation, due to pelvic congestion, leucorrhea increases, and there are many leucorrhea, sometimes with blood, which will be slightly brown when corpus luteum function is insufficient.

When women have sex after marriage (including pre-marital sexual fantasies, sexual masturbation and sexual impulses), pelvic congestion will be caused by sexual excitement, and then vaginal secretions will increase greatly, and leucorrhea will increase significantly. The longer the stimulation time, the stronger the stimulation and the more secretions. These are normal physiological phenomena and physiological reactions.

However, although some women pay great attention to cleanliness, they have a lot of leucorrhea; The smell is very strong, making people cover their noses; Or the color and nature of leucorrhea have changed obviously, which means that there is an abnormal situation. When these situations happen to married women, the first consideration is related to sexual activities.

Abnormal leucorrhea: usually a manifestation of reproductive tract inflammation. Married women are generally more susceptible to infection, which has a considerable relationship with their frequent sexual life. Men don't wash their hands when caressing with their hands, and their nails are too long to hide evil and shelter evil people; Before sleeping together, one or both parties do not pay attention to cleaning the lower body, especially the man's poor hygiene habits; The man suffering from phimosis or too long foreskin, too lazy to urinate and clean after the same room, are all important reasons for abnormal female leucorrhea.

According to the color, smell and nature of leucorrhea, we can preliminarily judge the pathogenic type:

When infected with pyogenic bacteria, leucorrhea is purulent, yellow or yellow-green, sticky and purulent, with a bad smell, such as senile vaginitis, endometritis, uterine cavity empyema, gonococcus vaginitis and non-gonococcus vaginitis (chlamydia infection).

When fungal infection occurs, leucorrhea is like bean curd residue, accompanied by obvious vulvar itching, such as candida infection.

When infected with trichomonas, leucorrhea is milky foam and vaginal itching.

However, the abnormal performance of leucorrhea is not as typical as mentioned above, and mixed infection often occurs, so it is impossible to make a clear diagnosis only by simple appearance judgment. It's best to go to gynecology for routine examination in order to get a definite diagnosis and timely treatment. Especially when one or both parties have a history of unclean sexual intercourse, they should actively seek medical treatment, and it is best to go to the dermatology department to avoid misdiagnosis or missed diagnosis.

At present, the medical community has effective drugs for bacterial (including gonococcal), fungal and trichomonal vaginal infections, so after finding out the cause, we can get effective treatment with strong pertinence. Patients with leucorrhea, especially older or menopausal patients, should be more vigilant and seek medical treatment as soon as possible to avoid delaying the diagnosis and treatment of tumors.

In addition, it should be pointed out that couples with gonorrhea or trichomoniasis must receive treatment at the same time. Otherwise, if only the woman is treated, the man will still be infected with bacteria or pathogenic microorganisms, and the woman will be infected again through sexual life after being cured.

The principle that prevention is more important than cure is still valid here:

In order to protect women's physical and mental health, both men and women should pay attention to sexual hygiene, especially husbands, and must develop good hygiene habits. The two most important things that must be done are:

(1) The man washes his lower body every day. Before having sex with him, he should pay more attention to cleaning all the parts where sexual contact may occur.

(2) Patients with phimosis should be circumcised as soon as possible. Although the foreskin is too long, you don't have to do this operation, but at least turn the foreskin up and clean it before the same room.

In addition to cleaning before the same room, the woman has to urinate and clean her lower body again after the same room. At ordinary times, we should also pay attention to separate the towels and washbasins for washing your face from those for washing your feet. Use squatting toilets as much as possible. Toilet paper should be padded when sitting. Toilet paper should be wiped from front to back. Menses should be washed and changed frequently. Sanitary napkins should not be stingy. , can prevent abnormal leucorrhea.
