Is height purely genetic?

Edit Post

My dad is 170cm(5'7) tall, and my mom is 158cm(5'2) tall. I ended up being 172cm tall. When I was in middle school and high school, I usually sleep late and did not eat much. I'm wondering if it's the bad habit stopped me from growing taller or is it just genetics. I was tall when I was a kid. I was 167cm tall when I was 12 yrs old. I only grew 5cm after that. Does anyone have a similar experience as mine？It sucks to see all my friends that were shorter than me before are towering over me now...

I am 173, strangely mine experience parallels yours.
I was 168 by 14 but i only grew 5 cm between 14-17, and i stopped after that.
I slept late too and did not eat much, school was really stress, plus mine mum was diagnosed with cancer , some days i barely get any sleep at all and school requires me to get out of bed by 6am. So yeah, it is quite possible mine lifestyle affected mine height.

I think you maxed out your genetic potential lol.

It's extremely difficult to be malnourished to the point where height was affected in a first world country. Based on your parents' height, you're very fortunate that you are 172 cm. A lot of people have their growth plates fuse early, and that may be why you did not grow that much after 12. My growth plates fused when I was only 15, just like my mom.

Thanks. I would feel much better if being short has nothing to do with my bad habits before. I have nothing to regret then. This is my destiny, and unfortunately I'm not a genetics lottery winner.
