Background:
There may be an etiological association between obesity and dysmenorrheal traits. This study aimed to observe the relationship between body mass index (BMI) and dysmenorrhea in a general female population.
Methods:
Premenopausal adult females (n = 2,805) undergoing health checkups were assessed for data such as the BMI and self-reported severity of dysmenorrhea. The BMI levels were compared according to the severity of dysmenorrhea with adjustment for age, smoking habit, exercise habit, serum lipids, and plasma glucose.
Results:
The mean BMI level in females with severe dysmenorrhea (n = 278; 23.3 ± 4.5 (standard deviation) kg/m2) was high relative to those with mild (n = 1,451; 22.3 ± 3.9 kg/m2) and moderate (n = 1,076; 22.6 ± 4.4 kg/m2) dysmenorrhea. Even after adjustment for covariables, the difference in BMI remained significant.
Conclusions:
The high-normal BMI level may be seen in severe dysmenorrhea in the general female population. Further research is needed to confirm the findings.

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...
01:22Hormonal 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...
