According to the latest research shows that overweight women (BMI greater than 27) chance of anovulatory infertility, is normal weight women (BMI values between 20~25) 3.1 times times underweight women (BMI values is less than 17) chance of infertility is 1.6 times times the normal-weight women!
You do also have a situation of too fat or too thin? Or your excessive weight loss because of the new solution? Be careful, your weight will affect pregnancy!
Hormones affect ovulation
On female,, ovarian of main function for \' ovulation \' and \' secretion sexual hormones \', but ovarian of function not spontaneous, but was pituitary gland and Xia depending on Hill of control; relative of, ovarian by secretion of sexual hormones also will feedback control pituitary gland and the Xia depending on Hill of secretion function, so formation a full of \"Xia depending on Hill-pituitary gland-ovarian\" axis, dang this gonad reproductive axis H-P-O system of function was interference, led no ovulation, on will caused menstrual does not rules and the infertility.
HYPOTHALAMUS release \"gonad-stimulating hormone-releasing hormone\", you can stimulate the secretion of pituitary gland \"effect of promoting filtration bleb\" and \"promoting lutein\", and thus stimulate the secretion of ovarian follicular granulosa cells in \"Estrin\", and to promote of follicular oocytes matured, while promoting endometrial thickening.
When women\'s weight is too low: causes the pituitary gland secretion promotes follicular hormone and luteinizing hormone insufficient, leading to reduced secretion of ovarian, gradually lead to chronic Anovulation and infertility.
When women are overweight: can cause uncoordinated increase male and its female hormones in the body, resulting in patients with Polycystic ovary disease Hou Qun and hairy, further leading to chronic ovulation and infertility.
Overweight or underweight pregnant women may result in adverse consequences
Overweight during pregnancy:
(1) of the mother: chronic hypertension increased 10 times, gestational diabetes increases 10~17 times.
(2) to the fetus: congenital heart disease increased 6 times, neural tube defects increased twice times, giant baby (birth weight >4000 GM) increases by 10 percent.
(3) production complications: production labor or birth, fetal shoulder dystocia, dystocia injured increases, increases the risk of caesarean 2~3 times.
(4) postpartum complications: enhances the four degree laceration of perineum, chance of postpartum hemorrhage.
Underweight during pregnancy:
(1) of the matrix: can lead to anemia in pregnant women, leg edema, chronic hypertension, eclampsia.
(2) to the fetus: underweight, growth retardation of fetus.
Too heavy or too light, many problems!
Women are overweight or underweight, subject to easy to cause menstrual irregularities, infertility and chronic Anovulation outside, causing lesions to various organs of the body can easily, for example:
Overweight: easily lead to malignant neoplasms, cerebrovascular disease (stroke), heart disease, diabetes, gout, osteoporosis, sexual dysfunction, gallbladder disease, Endometrial hyperplasia, increased incidence of breast cancer after the menopause.
Underweight: often poor spirit, sleepiness, defecation difficulties, emotional instability, hypoproteinemia, malnutrition, reduced immune function, serious cause multiple organ failure.
TIPS: body mass index (BMI) calculation: weight (kg) divided by height (in meters) squared:
BMI<18.7 → underweight
BMI=18.7~24.99 → normal weight
BMI=25~29.99 → overweight
BMI reaches 30 → obesity.
Clearly, women\'s ideal BMI values is 20.8, between 18.7 (lower limit) and 23.8 (Cap), the CAP is an overweight; as regards the male ideal BMI values for 22, between 20 (minimum) and 25 (the maximum), the CAP it is overweight.
