Mood and physical symptoms during the menstrual cycle correlate with low-grade inflammation in women, regardless of body weight. These inflammatory changes are linked to daily symptom fluctuations.
Area of Science:
- Reproductive Endocrinology
- Immunology
- Psychoneuroendocrinology
Background:
- A link exists between mood, low-grade inflammation, and obesity.
- This study investigates menstrual cycle-related changes in symptoms and inflammatory markers.
Purpose of the Study:
- To examine the relationship between physical and psychological symptoms and inflammatory markers throughout the menstrual cycle.
- To compare these changes in normal weight versus overweight women.
Main Methods:
- Assessed 15 times throughout the menstrual cycle.
- Collected fasting blood samples for inflammatory markers (hs-CRP, TNF-alpha).
- Recorded symptoms using the Freeman Daily Symptom Record.
Main Results:
- Serum hs-CRP levels and symptom scores (total, mood, behavior, physical) varied significantly and paralleled each other during the menstrual cycle.
- hs-CRP correlated with total symptom scores and mood, behavior, and physical symptom factors, independent of weight status or gonadal steroids.
- Tumor necrosis factor-alpha levels did not show these associations.
Conclusions:
- Healthy young women experience psychological and physical symptoms during the menstrual cycle.
- These symptoms change in association with alterations in low-grade inflammation.
- The observed associations are independent of body weight or gonadal steroid levels.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
Menses Phase
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...
