What causes pain and nausea in the left lower abdomen of women?

Many people feel that women are inherently weaker than men because of the limitations of their physical functions. In our lives, we often see many women suddenly experiencing left lower abdominal pain and nausea or suddenly feeling very tired. Therefore, most men have the impression that women are delicate. In fact, these seemingly ordinary things are not women’s nature, but have a great relationship with women’s health. Today we invited relevant experts to explain why women experience pain and nausea in the lower left abdomen?

1. Ovulation abdominal 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. 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 pattern, 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.

3. 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.

4. 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.

5. Pregnancy-related diseases

Abdominal pain caused by pregnancy-related diseases can be seen in threatened abortion, ectopic pregnancy, etc. Taking ectopic pregnancy as an example, dull pain or distension in the adnexal area on the affected side may occur. When the ectopic pregnancy occurs miscarriage or ruptures, it can cause intra-abdominal bleeding. The pain symptoms vary depending on the amount and speed of bleeding. If it is a miscarriage due to fallopian tube pregnancy, the abdominal pain is often limited to one side of the lower abdomen, and blood accumulates in the rectouterine pit, which can cause anal pain. When the fallopian tube pregnancy ruptures, the amount of bleeding is large and the speed is fast. The blood quickly spreads to the entire abdominal cavity and causes pain in the whole abdomen.

6. Acute appendicitis

It is a common lower abdominal pain in young girls. It is a surgical disease, but it needs to be differentiated from gynecological diseases. About 70% to 80% of patients initially feel pain in the upper abdomen or around the navel, which then moves to the right lower abdomen a few hours later. The pain of simple appendicitis is limited to the right lower abdomen and may be continuous or paroxysmal. The abdominal pain of suppurative appendicitis worsens, often presenting as paroxysmal severe pain or bloating. Necrotizing appendicitis begins with persistent throbbing pain, and the area of ​​abdominal pain expands and the severity becomes more severe. In the early stages, there is often mild nausea and vomiting of food, often accompanied by loss of appetite and constipation. Abdominal distension may occur when inflammation is severe. The presence of migratory right lower abdominal pain is a characteristic of appendicitis. The disease generally requires surgical resection.

7. Psychogenic abdominal pain

For example, a girl with school phobia is afraid to go to school and take exams. If the patient is forced to go to school, she will experience anxiety and anxiety-related physical discomfort, such as pale complexion, rapid heart rate, rapid breathing, unbearable abdominal pain, vomiting, headache and dizziness. Some patients have visited the doctor for severe abdominal pain many times, but the results of various examinations were normal. Once the patient is allowed to temporarily take a leave of absence from school, the anxiety and discomfort symptoms will soon be relieved and the abdominal pain will disappear immediately. Such patients require psychological treatment.

The above seven factors will cause women to suddenly experience pain and nausea in the lower left abdomen. We all know that menstruation is very important for women. Therefore, if you want to improve problems such as dysmenorrhea, female friends should pay attention to keeping warm in daily life. Even in the hot summer, do not use air conditioning for a long time, and should drink very little cold drinks. In addition to conditions such as dysmenorrhea, it is best to go to the hospital for treatment in time for other causes. We also hope that our female friends can stay away from diseases and stay healthy.
