It's a common occurrence for women, so it's not surprising. But do you know the hidden crisis behind these inexplicable abdominal pains? In fact, what we usually call "stomachache" is a big concept. It is not a disease name, but a symptom. There are many reasons for abdominal pain in women, almost involving various diseases. What concerns women most and is easily deceived by the superficial phenomenon of abdominal pain is women's arch-enemy-gynecological diseases. The superficial symptoms of dysmenorrhea: abdominal distension and pain, mental tension, depression, fear, and emotional instability: whether there is vomiting and syncope during menstruation, whether you can persist in your work and whether you need to stay in bed. Search keywords: before and after menstruation or during menstruation, people who have abdominal pain and thus affect their work and life are called dysmenorrhea. Dig into the truth: dysmenorrhea can be divided into primary and secondary. Gynecological examination shows that dysmenorrhea with no obvious abnormality in uterus or pelvic cavity is primary dysmenorrhea, and the self-healing rate of this kind of dysmenorrhea can be improved with age. Because the occurrence of primary dysmenorrhea is related to endocrine factors, taking contraceptives after marriage to inhibit ovulation can make dysmenorrhea disappear. If there are obvious pathological changes in reproductive organs, such as dysmenorrhea caused by endometriosis, pelvic inflammatory disease and tumor, it is called secondary dysmenorrhea. There are also local factors such as uterine muscle spasm, increased tension in uterine isthmus, excessive uterine flexion, cervical stenosis and uterine malformation. When the pain is severe, the patient has pale face, cold sweat, cold hands and feet, nausea, vomiting and even syncope and collapse. Therefore, long-term dysmenorrhea can not be ignored, especially for women of childbearing age, small dysmenorrhea may affect fertility. Surface phenomenon of ovulatory abdominal pain: some girls always have abdominal pain half a month after menstruation is clean, which is generally manifested as dull pain or swelling pain, sometimes left and sometimes right, and the time is short. Measurement standard: Because both ovaries ovulate alternately, abdominal pain occurs alternately in both lower abdomen, sometimes accompanied by bleeding. Search keywords: Abdominal pain occurs between two menses of girls or women of childbearing age, that is, when they are ovulating, and will stop after one or two days. Gynecology calls this kind of abdominal pain "ovulation abdominal pain" or "ovulation abdominal pain". Get to the bottom of the truth: after menstruation, a mature egg is discharged from the ovary every month. Fibrous tissue rupture will occur in the ovary, and occasionally small blood vessels and nerves will be damaged to produce pain. In addition, when ovulating, a small amount of liquid in the egg cell overflows into the abdominal cavity, which stimulates the peritoneum and also causes abdominal pain. 20% patients with ovulatory abdominal pain can have ovulation bleeding at the same time, but the amount of bleeding is small and the duration is short. Ovulatory abdominal pain is a normal physiological phenomenon. Therefore, patients don't have to panic and worry about it. With the increase of age, the symptoms will gradually decrease.
