Causes of lower abdominal pain in women

1. Ovulation abdominal pain

Ovulation pain

When adolescent girls ovulate, the follicle ruptures and the follicular fluid may have a certain stimulating effect on the peritoneum, so they sometimes experience mild abdominal pain that alternates between the left and right sides once a month. This is physiological, and the symptoms are mostly unilateral lower abdominal pain, dull pain or heaviness-like pain. Some girls also have a small amount of vaginal bleeding, that is, ovulation bleeding, which usually disappears on its own after one or two days, and generally does not exceed seven days. This type of abdominal pain usually does not cause any pathological changes, and the gynecological examination is completely normal. It is physiological abdominal pain and generally does not require treatment.

2. Ectopic pregnancy

Ectopic pregnancy refers to the implantation of the gestational sac outside the uterus. Among ectopic pregnancies, about 95% occur in the fallopian tube. Abnormal fallopian tube development, abnormal fallopian tube function, tumor compression, and downward migration of the intrauterine contraceptive device may all cause ectopic pregnancy. Lower abdominal pain is one of the common symptoms of ectopic pregnancy. In addition, ectopic pregnancy is also accompanied by symptoms such as amenorrhea and irregular vaginal bleeding.

3. Dysmenorrhea

Dysmenorrhea is divided into primary and secondary dysmenorrhea. Primary pain is often seen in adolescent girls. It is related to the level of prostaglandins in the body, cold, emotional and psychological factors, but there is no organic disease. It can generally heal itself with age or after marriage and childbirth. Common causes of secondary pain are endometriosis and adenomyosis. The symptoms include gradually increasing pain, often in a cyclical manner, or dull pain in the lower abdomen during non-menstrual periods that worsens before and after menstruation. In addition, it is often accompanied by infertility and menstrual disorders, which often require drug treatment.

4. Ovarian Corpus Luteum Rupture

This is caused by excessive bleeding in the corpus luteum, accompanied by sudden onset of abdominal pain in the lower abdomen or one side, and in severe cases, shock may occur. Most cases of ovarian corpus luteum rupture occur between the 20th and 26th days of the menstrual cycle, and lower abdominal pain may occur at the onset, with varying degrees of severity. Before the corpus luteum of the ovary ruptures, the ovary will experience congestion and swelling. This process can be triggered when the ovary is affected by external or indirect external forces, especially when it is congested before menstruation, such as due to straining during bowel movements, trauma, sexual intercourse, or strenuous activity. It is best to go to the hospital for diagnosis and treatment immediately after the occurrence of ovarian corpus luteum rupture. Do not abuse painkillers on your own to avoid masking symptoms and affecting normal diagnosis and treatment.

5. Ovarian cyst pedicle torsion or rupture

This is because the cyst has a long pedicle, a large volume, no adhesions to the surrounding area, and is highly mobile, and twists when affected by intestinal peristalsis or changes in body position. When the pedicle of an ovarian tumor is twisted, pain suddenly occurs on one side of the lower abdomen, which is persistent colic, often accompanied by nausea and vomiting; there may be obvious tenderness and muscle tension in the abdomen; digital rectal examination may reveal swollen and tender appendages. Ovarian cysts may also rupture, and the contents of the cysts may irritate the peritoneum and cause severe pain. B-ultrasound examination can confirm the diagnosis. Emergency surgery is usually required.
