But keep in mind that puberty starts when a boy's body is ready, and everyone grows at his own pace. You might have noticed that some of the girls you know are taller than the boys.
But you've probably noticed that out of the adults you know, most of the men are taller than the women. Well, girls get a head start on puberty — and growing taller — because they usually start these changes between the ages of 8 and 13.
You may have already noticed some boys starting to get chest muscles (called the pectoralis muscles or pecs for short).
There aren't any exercises or magic pills to make you grow tall.
But by being active and eating nutritious foods, you're helping your body grow up healthy, just the way it should.
You may feel moody and depressed one minute and enthusiastic and excited the next.
A lot of changes happen as you grow up, especially as you reach puberty (say: PYOO-bur-tee), the name for the time when your body begins to develop and change. For a guy, there isn't just one event or sign that you're growing up.
Most boys may catch up — and even grow taller than girls.
But it's also important to remember that your genetics play a role in height.So if your mom and dad are tall, you're more likely to be tall.And if your mom and dad are kind of short, you may be short, too. You have to wait and see how it turns out, but you can also talk to a doctor if you're concerned. Many men who are considered "short" have gone on to have careers in the movies, the military, and even professional basketball!For boys, this process usually begins between ages 10 and 12 and may continue for up to 4 years.During puberty the changes your body undergoes will be more rapid and dramatic than at any other time in your life.If you want more information on puberty and the changes happening to your body, talk to a trusted adult or call Kids Help Phone at 1-800-668-6868 and talk to one of our professional counsellors.
