What happens during puberty?

Your Question

Dear Alex. I am curious about my body and have noticed a lot of changes since I started puberty. 


Hi there, you are very welcome to Ask Alex.   

Thank you for contacting us. We know that talking about things like puberty can be a bit awkward at times so it’s fantastic that you were brave enough to reach out to find out more. 

Puberty is the process of growing from a child into an adult and it can be both an amazing and challenging stage of life! During puberty, the body goes through a series of hormonal and physical changes which prepare the body for adulthood and, particularly, sexual maturity. 

There’s no set age for the start of puberty because all bodies change and grow in their own time.  Although we sometimes think of girls and boys going through different physical processes in puberty, the signs and stages can be very similar.  

Physical Changes 

  • Both boys and girls are likely to have a sudden growth spurt. 
  • Both boys and girls will start to grow body hair. 
  • Both boys and girls will see changes in their weight and body shape, but these changes will differ in a boy or a girl.  

Emotional Changes 

  • Boys and girls will experience changes and swings in their moods.  
  • Both sexes are likely to begin to sweat more. 
  • Getting spots (pimples) is another sign of puberty and both boys and girls can get them.  

These are just some ways that our bodies change during the period of puberty, and it is all completely natural. We won’t all have the same things happen to our bodies at the same time either, and that is absolutely fine. You can read more about puberty here: and this article also includes a helpful video:
