could lead to early menopause
The usual age to enter menopause is around 50 years old, when a woman is well past her childbearing age. If a woman has no period for a year, she can be considered to have entered menopause. Getting an early menopause is quite devastating for women who try to have children in their late thirties.
There are some factors that can cause women to enter premature menopause, even before the age of 40, and only some of these factors are genetic or related to an autoimmune disease. Other factors can be traced back to your lifestyle as a teen (up to twenty-something years old).
#1. Drinking a lot of soda or sugar-filled drinks
A scientific study found that girls who drank sodas or sugary drinks daily got their period a few months earlier than those who did not drink such beverages. The excess sugar in those drinks leads to metabolic changes, weight gain and, because of that, to endocrine changes that hasten the first period.
#2. Being overweight or obese
Higher than normal weight or obesity are a real issue among American children. Child obesity is three times higher than it was in the seventies. Because fat generates an estrogen-equivalent hormone, overweight or obese girls are bound to start their cycle earlier.
#3. Start early, end early
The probability of early menopause is higher than 80% for women who had their first period before the age of 11. The exact mechanism is not yet clear, but the link is scientifically proven.
#4. No children
Choosing not to have any children or being unable to have them also raises the probability of early menopause. The probability is even higher for women with early-starting periods. Why the link exists is not clear either, but it exists nonetheless.
#5. Smoking
A study shows that about 14% of women who smoke have a 26% chance to experience early menopause and a greater risk of infertility. The toxins in tobacco smoke can change the hormonal balance, adversely affecting the fertility cycles and the embryo’s ability to attach to the uterine wall.
#6. Cancer
The hormone balance of the reproduction.
