Do frequent hunger and "sleepy" feeling indicate upcoming rapid growth/spurt?

Taddy Asked: Do frequent hunger and "sleepy" feeling indicate upcoming rapid growth/spurt?

Hi guys!

I have been very hungry since the last week and I think it means some "changes" in my body..

I'm a 15 years old guy and my height is 5'5 1/2" – 5'6"
I think I'm either undergoing a long term growth spurt or another one is starting, because I was 4'10" when I was 13, so I think I started growing later than others.

I eat VERY healthily (I also eat fast food and drink some Coca-Cola once a week) but I'm kinda slim – ~105 lbs; however, the doctor says it's normal at this age and also there's a fact my dad was 22 lbs lighter than me at this age…
I sleep 6 – 7 hours during the school year and 10 – 12 hours during the summer holidays.
My shoe size is 42 EU/US 8,5; my dad's shoe size is exactly the same.
I have also been experiencing some back pains (nothing serious) and fatigue.
I'm usually very tired even after 12 hours of sleep.
I'm healthy, no diseases, nothing.

Parents height:

Dad 5'10"
Mom 5'1"

My predicted height is 6' or something just under 6' (that would be awesome)!

Thanks all who have time to read through this sh33t, I really appreciate that.
Also kindly pardon my English, because it's not even remotely my mother tongue…

Sincerely, Taddy
