Do girls who play sports get their periods later?

Yes, highly active girls, especially those training intensely without enough calories, can experience their first periods later or have irregular periods (amenorrhea) because the body prioritizes energy for sports over reproduction, a condition linked to Relative Energy Deficiency in Sport (RED-S). While some athletes get their first period slightly later, a significant delay or loss of periods isn't normal and signals an energy imbalance that needs attention from a doctor.

Is it normal for athletes to have late periods?

Amenorrhea is hardly a new issue in the world of endurance sports. Studies over the years have reported that over 60% of women athletes have what is known as “Athletic Amenorrhea,” that is disturbed menstruation due to the demands of high intensity training on the body. My question is, why? In almost every other arena.

Does playing sports affect your period?

Any changes in normal hormone levels can lead to menstrual dysfunction, especially in athletes. This can be caused by overtraining, stress, dieting and weight loss. Typically, menstrual dysfunction occurs when the amount of energy used by athletes exceeds the amount of energy taken in through nutrition.

Do sports delay puberty in girls?

The participation of women in sports is increasing, and the rising training demands may impact growth and pubertal development. High-intensity sports are often linked to delayed growth and bone maturation due to energy deficits and intense regimens.

Can starting a sport delay your period?

Yes, exercising too much can cause missed or irregular periods, or even stop your period entirely. This is called secondary amenorrhea. Here's why: Physical stress Exercise puts stress on your body, which can signal your brain to stop producing reproductive hormones.

What triggers late periods?

A late period is often caused by stress, hormonal changes from birth control, weight fluctuations, extreme exercise, or conditions like PCOS or thyroid issues, disrupting the normal ovulation cycle. While pregnancy is a primary reason, lifestyle factors (sleep, diet, stress) and health issues (diabetes, thyroid disorders, menopause) significantly impact regularity, requiring medical consultation if persistent.
 

Why has my teenager missed her period for 3 months?

A teenager missing their period for three months (secondary amenorrhea) needs a doctor's evaluation to find the cause, which could range from pregnancy, stress, extreme exercise, or eating disorders (like anorexia/bulimia) to hormonal issues (thyroid, PCOS), certain medications, or underlying conditions, as untreated amenorrhea can affect bone health. A doctor will perform history, exam, and possibly blood tests to diagnose and treat, often with lifestyle changes or hormones like birth control.
 

Do skinny girls hit puberty later?

In the US, the age at menarche decreased by 3 years since 1840 due to improvements in the population's nutritional status. Underweight females generally experience menarche at later ages than normal weight females. In contrast overweight females often experience menarche earlier than the average weight female.

Do gymnasts get periods later?

Some gymnasts may experience what's considered primary amenorrhea, meaning they have not started their period by 15 ½ years of age. This is usually due to inadequate energy availability for high level athletes.

When in your cycle are you most athletic?

The follicular phase and athletic performance

With a lower level of hormones during the first phase of your menstrual cycle, your body is primed to maximize hard training efforts. This means your body is better able to access stored carbohydrates, making this an ideal time for high-intensity training.

How much delay in periods is normal?

A delay of up to 7 days (or around a week) past your expected period is generally considered normal due to factors like stress, illness, or routine changes, with typical cycles ranging from 21-35 days. However, a period more than a week late warrants a pregnancy test if you're sexually active, and consistently missing periods or delays over 90 days (three months) without pregnancy should prompt a doctor visit for potential underlying issues like PCOS or thyroid problems. 

Do athletic girls have less periods?

The most well-known health-related threat to female athletes is the loss of the menstrual cycle, which endocrinologists and gynecologists mainly refer to as functional amenorrhea.

What is the female athlete syndrome?

"Female Athlete Syndrome" usually refers to the Female Athlete Triad, a serious health issue for active females involving low energy availability (not enough calories for activity), menstrual problems (missed or irregular periods), and poor bone health (low bone density/osteoporosis). It stems from inadequate fueling, leading to impaired bodily functions, increased injury risk (like stress fractures), fatigue, and psychological distress, and is now understood as part of a broader condition called Relative Energy Deficiency in Sport (RED-S) that affects all athletes.
 

What can throw off your menstrual cycle?

Stress, major weight changes, intense exercise, hormonal issues (like PCOS, thyroid problems), certain medications (birth control, antidepressants), and health conditions (diabetes, endometriosis) can disrupt your menstrual cycle, causing late, missed, or heavier periods by affecting the delicate hormonal balance that regulates ovulation and menstruation. Lifestyle shifts, perimenopause, and even illness can also be factors. 

Does being athletic make your period come later?

The term for when someone who isn't pregnant or menopausal misses three or more periods is secondary amenorrhea. (Primary amenorrhea is when a girl has not gotten her first period by age 15.) Exercise alone won't cause you to miss periods. Rather, it's the combination of exercise and not eating enough.

How long after breast buds does the period start?

Your first period (menarche) typically starts about 2 to 2.5 years after breast buds (small lumps under the nipple) first appear, though the timing varies, with some starting earlier or later. Puberty progresses, with pubic hair often appearing next, followed by a growth spurt, and then the first period. 

What level was Simone Biles at age 11?

Level 10 is the highest level in the USA Gymnastics Junior Olympic Program, but no one at her gym had ever reached level 9. At the age of 11, Simone accomplished this feat. This was astonishing because the only junior gymnasts who ever made it to level 9 were those who wanted to pursue an elite career in gymnastics.

What age do girls gain the most weight?

Females tend to gain the most weight during midlife, particularly between ages 40 and 65, with significant changes often occurring during the perimenopause and menopause transition (around ages 45-55) due to hormonal shifts (declining estrogen), decreased muscle mass, and lifestyle factors, leading to about 1.5 pounds of gain annually during this period, although some studies suggest notable weight gain also occurs in the 20s and 30s.
 

What are the 5 stages of girl puberty?

The five stages of puberty in girls, known as Tanner Stages, track physical development from prepubertal (Stage 1) to adult maturity (Stage 5), focusing on breast and pubic hair growth, with stages involving breast buds, growth spurts, coarser hair, potential menstruation (menarche), and final adult body shape. Each girl develops at her own pace, but the general sequence involves initial breast budding (Stage 2), thickening pubic hair, accelerated growth, and eventually menstruation and adult breast/hair patterns.
 

What delay puberty in girls?

Delaying puberty in girls usually involves addressing underlying causes like low body fat (due to extreme sports/eating disorders), chronic illness, or genetic factors, but it's often just a normal "late bloomer" pattern in families. Medical intervention, like low-dose estrogen, might be used if there are concerns or a significant delay (no breast development by 13), but often reassurance and monitoring by a doctor, especially a pediatric endocrinologist, is enough to manage social concerns and ensure healthy development.
 

What triggers a girl's first period?

Your first period (menarche) is triggered by hormonal changes from puberty, driven by your brain (hypothalamus & pituitary gland) signaling your ovaries to release estrogen and progesterone, building the uterine lining, which sheds when an egg isn't fertilized, typically 2-3 years after breast development starts. Factors like genetics, body fat, nutrition, stress, environment, and overall health influence the timing, usually around ages 10-16.
 

What is a ghost period?

A "ghost period" (or phantom period) is when you experience all the symptoms of a menstrual period—like cramping, bloating, mood swings, and back pain—but without any actual bleeding. This happens because your body goes through hormonal shifts that trigger period-like feelings, but the uterine lining isn't shed, often due to stress, hormonal birth control, endometriosis, perimenopause, or anovulation (skipping ovulation).
 

Why do periods delay in teenage girls?

However, they may be caused by a hormone imbalance, excessive weight loss or exercise, pregnancy, medications, stress, and a myriad of other problems. This is why it's important for a teen girl to see a health care professional if she's stopped getting her periods or is late in starting them.
