It has been a misconception that most people believe that teenage girls do not suffer from gynecological diseases. Like adults, teenage girls have a uterus, ovaries, fallopian tubes and vagina. The existence of organs has the possibility of disease, but the incidence of gynecological inflammation and tumors in unmarried, young girls is low, but not immune to disease. The day before yesterday, a 14-year-old girl had abdominal pain for 7 days. Her mother took her to the internal medicine department of several hospitals and used antimicrobials and painkillers all over, but the pain was not stopped. If she had thought of gynecological diseases earlier, she might have been able to save her fallopian tubes if she had gone to the gynecology department and had a gynecologic ultrasound earlier. In the same week, a 22-year-old unmarried girl was admitted to the hospital with a distended abdomen like a full-term pregnancy, her bones were as thin as wood, and her abdominal wall was bruised. When will the psychological shadow be removed? There are countless cases like this, and we only hope that parents and unmarried girls will think of gynecological diseases when they have abdominal pain and other discomforts! Many parents think that dysmenorrhea is a normal phenomenon, but they do not know that some dysmenorrhea is caused by abnormalities of the reproductive organs, which can lead to pain and menstrual blood entering the abdominal cavity because the abnormal menstrual blood does not flow or cannot flow completely, and the presence of a large amount of menstrual blood in the body can cause inflammation and can destroy the fallopian tubes, leading to infertility. Therefore, girls who have menstrual pain at the first menstruation should go to the hospital for an ultrasound to rule out reproductive organ malformations. The following gynecological diseases are common in young girls: 1. vaginitis in young women; 2. ovarian tumors; 3. ovarian crown cysts; 4. malignant tumors of the ovaries; 5. malformations of female reproductive organs: hymenal atresia, vaginal atresia, vaginal diaphragm, diaphragm, longitudinal diaphragm, cerviceless uterus, vestigial uterus, hermaphroditism, no vagina, no uterus.
