Summary
Central sensitization symptoms affect about half of women and are linked to menstrual pain, irregular cycles, and gynecological issues. Early-onset dysmenorrhea significantly increases this risk.
Area of Science:
- Gynecology
- Pain Medicine
- Epidemiology
Background:
- Dysmenorrhea is a common pain condition affecting women of reproductive age.
- Chronic pain can predispose women to Central Sensitization.
- Understanding the link between menstrual characteristics and central sensitization is crucial.
Purpose of the Study:
- To investigate the association between menstrual characteristics and central sensitization symptoms in women.
- To identify specific menstrual factors that increase the likelihood of developing central sensitization.
Main Methods:
- A cross-sectional study involving 10,402 Brazilian women.
- Data collected via an online questionnaire including gynecological history, pain scales, and the Central Sensitization Inventory.
- Statistical analysis using binary logistic regression to compare women with and without central sensitization symptoms.
Main Results:
- Dysmenorrhea prevalence was 67.3%.
- Higher menstrual pain intensity, gynecological diseases, early-onset dysmenorrhea (since adolescence), and irregular menstrual cycles were associated with increased odds of central sensitization symptoms.
- Specifically, odds ratios were 1.12 for menstrual pain, 1.51 for gynecological diseases, 1.20 for early-onset dysmenorrhea, and 1.47 for irregular cycles.
Conclusions:
- Central sensitization symptoms are prevalent, affecting approximately 50% of women.
- These symptoms are significantly associated with dysmenorrhea intensity, cycle regularity, early onset of dysmenorrhea, and co-existing gynecological diseases.

The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...

Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
