Why Are Girls Getting Periods Earlier? Causes and What Parents Should Know

Are girls starting their periods earlier?

Many parents feel that girls today start their periods younger than they did. They are right. Studies in many countries, India included, show girls starting their periods a little earlier than a generation ago. This guide explains why, what it can mean, and how to help your daughter feel ready.

What age is normal?

Most girls get their first period between about 10 and 15. It usually comes about two years after the breasts start to develop. Every girl is different.

Puberty that starts very early is a reason to see a paediatrician. Take your daughter to one if her breasts start to develop before age 8, or if her first period comes before age 10. Sometimes there is a medical cause that needs treatment. Puberty that starts too early can also make a girl stop growing sooner, so a doctor's check is worth it.

Why are periods starting earlier?

Family

Girls often start their periods at about the same age as their mother did.

Body weight

Better nutrition is good news. But higher body weight in childhood is linked with earlier puberty, because body fat plays a part in the hormones that start it.

Chemicals around us

Some chemicals in plastics and cosmetics may affect hormones. Research is still going on. Simple steps, such as not heating food in plastic, are sensible.

Stress

Some studies link long-term stress in childhood with earlier puberty.

How early periods can affect girls

Feelings

A girl who starts before her friends may feel awkward, alone or embarrassed. Her body may change before she feels ready for it. She may also face teasing or unwanted attention.

School

A girl who does not know what to expect, or has nowhere to change at school, may stay at home during her period. Being prepared helps her keep going to class.

Health

Studies link an early first period with a slightly higher risk of some conditions later in life, such as breast cancer and heart disease. For any one girl, the extra risk is small. Healthy habits through life help.

How to help your daughter

Talk early

Do not wait for the first period. Start simple talks about growing up well before it, even from age 7 or 8. Keep it calm and matter of fact, so she knows a period is normal and nothing to fear.

Explain what happens

Tell her what a period is, how long it lasts, and what to use. Show her a pad and how it works. Pads, cloth pads washed with soap and dried in sunlight, and period panties are all good choices for a young girl. Our guide to busting menstrual myths and our menstrual quiz can help you both.

Pack a small kit

A pad or two, spare underwear and a small bag in her school bag means she will not be caught out.

Keep healthy habits

Encourage home-cooked meals, fruit and vegetables, and plenty of active play. Do not put a child on a diet. If you are worried about her weight, talk to a paediatrician.

Talk to her school

Find out whether there is a clean toilet with water, and a teacher she can go to if her period starts in class.

Never shame her

Her body is growing as it should. Praise her for asking questions, and keep answering them.

When to see a doctor

  • Her breasts start to develop, or pubic hair appears, before age 8.
  • Her first period comes before age 10.
  • She has no period by 15, or none within three years of her breasts starting to develop.
  • Her periods last more than 7 days, or she soaks through a pad every hour or two.
  • She has heavy periods and bruises easily or has frequent nosebleeds.
  • Period pain keeps her away from school.
  • Early changes are making her very unhappy or anxious.

FAQs

At what age do most girls get their first period?

Most girls get their first period between about 10 and 15, usually about two years after their breasts start to develop.

Is a first period at 8 or 9 normal?

It is earlier than usual. If your daughter's period starts before 10, or her breasts start to develop before 8, take her to a paediatrician to check that all is well.

Can lifestyle changes delay early periods?

There is no sure way to delay puberty. Healthy meals and active play are good for her at any age. If there is a medical cause, a doctor can advise on treatment.

What should I do if my daughter gets her period early?

Stay calm and reassure her. Make sure she knows what is happening and has what she needs. If she is younger than 10, see a paediatrician.

Are there long-term risks with early periods?

Studies link an early first period with a slightly higher risk of breast cancer and heart disease later in life. For any one girl the extra risk is small, and healthy habits help.

In short

Girls are starting their periods a little earlier than a generation ago. Talk to your daughter early, help her feel prepared, and see a paediatrician if puberty starts before 8 or her period comes before 10.
