Heads up if your first period came super early—or late. By early, we’re talking before the age of 10 and by late we mean after 17. Scientists have found that women who first started menstruating way outside the normal age range may be at a higher risk for heart disease, stroke, and high blood pressure compared with women who got their first period at age 13, who had a lower risk. “The age of menarche has been shown to be associated with a lot of things related to woman’s health—particularly early menarche, with an increased risk for cardiovascular disease,” says Martha Gulati, MD, professor of medicine and division chief of cardiology at the University of Arizona-Phoenix. The reason for the link is unclear, and of course, the findings are not definitive. Here’s what we do know ups your risk of heart disease, and how to cut your chances.

Or, the scale may influence when you get your period. Research has shown that getting your period before age 12 has been associated with increased body fat in early adulthood and obesity later in life. But, kind of like “the chicken or the egg” dilemma, it’s tough to say which came first. “Earlier menarche is likely associated with higher BMI in childhood,” explains Mary Pat Gallagher, MD, pediatric endocrinologist and assistant professor in the department of pediatrics at NYU Langone, “and an elevated BMI in childhood correlates to an elevated BMI in adulthood.” As an adult, find out why you might have a missed period when you aren’t pregnant.
Your first period may predict your risk of type 2 diabetesiStock/kzenon
In a study of more than 15,000 women, scientists found that those who got their period between ages 8 and 11 had a 70 percent higher incidence of type 2 diabetes compared to those who started menstruating at age 13. Obesity could be part of the link—research shows menarche at a younger age is associated with higher BMI in later life, and elevated BMI itself is a major risk factor for type 2 diabetes, according to the study authors. An increase in insulin resistance may factor in as well: Hormonal change at the onset of puberty is associated with what’s considered to be a benign increase in insulin resistance, explains Dr. Gallagher, who also serves as director of the Robert I. Grossman, MD and Elisabeth J. Cohen, MD Pediatric Diabetes Center at Hassenfeld Children’s Hospital of New York at NYU Langone. “Earlier exposure to the hormones of puberty could be responsible for a persistent change in insulin sensitivity that permanently changes the risk for type 2 diabetes later in life,” Dr. Gallagher says.

Preeclampsia is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organs, often the kidneys. If left untreated, it can be life-threatening for you and your baby. Research has shown women who get their period at age 10 or younger are three times more likely to develop preeclampsia compared to those who got their first period at age 13. If you’re obese and got your first period before age 11, your risk is even higher. These are the 8 period problems you should never ignore.
Your first period could affect your breast cancer riskiStock/lauranollphoto
There’s growing evidence that the longer you have your period, the higher your breast cancer risk. Women who start their menstrual period before age 12 have about a 20 percent higher risk of breast cancer compared to those who begin after age 14, research shows. Other research shows shows that hitting menopause at a later age—say, after 55, may up your breast cancer risk by 30 percent, versus women who stop before age 45. In a third study, scientists at the University of Oxford showed that a longer menstrual life—earlier periods and later menopause—is linked to specific types of breast cancer: estrogen-sensitive and lobular tumors. The findings suggest the more estrogen and sex hormones your body produces over your life span, the more likely your chances of developing breast cancers that are hormone-sensitive. You can’t control when you get your first period, but these habits to help prevent breast cancer are all you.

The average age at which a girl in the United States gets her first period is 12. The good news: Just because you got your period later doesn’t mean you’ll also enter menopause later. The bad news: Just because you got your period earlier doesn’t mean you’ll hit menopause sooner. Most women get their last period at aroung age 51. Genetics, smoking, and other factors may influence timing of your transition to menopause. Check out the signs menopause may be approaching.

Women whose periods begin later, and who experience menopause later in life, are more likely to live to be 90, suggests a recent study from the University of California-San Diego School of Medicine. Researchers found that women who started menstruation after age 12 were less likely to have certain health issues, such as coronary heart disease or diabetes, and those who experienced menopause after 50 were more likely to be in excellent health overall.
