Why does my left lower abdomen hurt during menstruation?

If you experience lower abdominal pain on the left side during menstruation, it may be due to dysmenorrhea. At this time, you should pay attention to good conditioning, but you should also be alert to some disease causes. The most common one is endometriosis, because this disease often aggravates the symptoms of dysmenorrhea during menstruation. There is also chronic pelvic inflammatory disease, which may cause symptoms of abdominal pain. You should go to the hospital for examination in time.

1. Endometriosis:

Dysmenorrhea manifests itself as secondary and progressive worsening. The so-called progressive pain means that the pain increases year by year as the local lesions worsen. It is mostly located in the lower abdomen and lumbosacral region, and can radiate to the vagina, perineum, anus or thighs. It often starts 1 to 2 days before menstruation, is most severe on the first day of menstruation, and gradually subsides and disappears when menstruation is over.

2. Chronic pelvic inflammatory disease:

Dysmenorrhea is characterized by a wide range of symptoms. Scar adhesions and pelvic congestion caused by chronic pelvic inflammation often cause lower abdominal distension, pain, and lumbar pain, which worsens before and after menstruation. Dysmenorrhea is manifested by persistent pain in the bilateral upper abdomen, which may radiate to the waist, and is sometimes accompanied by a feeling of heaviness and distension in the anus.

3. Adenomyosis:

Dysmenorrhea is characterized by progressive worsening. Severe spasmodic colic. It often occurs in multiparous women over 30 years old.

4. Submucosal uterine fibroids:

Dysmenorrhea is caused by the growth of fibroids toward the uterine mucosa, protruding from the uterine cavity, affecting the discharge of menstrual blood, thus causing abnormal contraction of the uterus and resulting in dysmenorrhea, which is manifested as lower abdominal distension, back pain, increased menstrual flow and irregular menstruation.

5. Chronic cervicitis:

The main symptom of dysmenorrhea is chronic cervicitis, which is characterized by increased vaginal discharge. When the inflammation spreads along the uterosacral ligament to the pelvic cavity, it will cause dysmenorrhea, which is mainly manifested as pain in the lumbosacral region and pelvic pain. The pain worsens during menstruation, defecation or sexual intercourse. Cervicitis caused by gonococci and other bacteria often leads to cervical canal occlusion or stenosis, causing retrograde menstrual blood and dysmenorrhea.

6. Pelvic congestion syndrome:

Dysmenorrhea manifests as a wide range of chronic congestive dysmenorrhea, with symptoms such as lower abdominal pain, low back pain, and breast pain during menstruation. The pain often worsens a few days before menstruation and eases on the first or second day after menstruation. In a few cases, the pain persists. The pain worsens after the patient has stood for a period of time and when running, jumping, or sitting down suddenly, and is more severe in the afternoon than in the morning. It is common in women aged 25 to 40.

7. Reproductive tract malformations:

Dysmenorrhea is manifested by mechanical obstructions such as excessive anteversion of the uterus and closure of the hymen, which cause poor menstrual blood flow and blood accumulation, inducing abnormal contraction of the uterine smooth muscle, thus causing dysmenorrhea. Generally, there is periodic lower abdominal pain that gradually worsens, and a gradually enlarging mass may appear in the lower abdomen.

8. Cervical or uterine adhesions:

Dysmenorrhea is manifested by adhesions of the cervix or uterine cavity, which causes poor menstrual blood flow and induces dysmenorrhea. It is more common in cases of repeated abortions, endometrial tuberculosis, etc.
