Teen growth spurt and weight gain

[Didi12]

Eldest has grown over the last 2 years from 5ft at the start of year 7 to 5ft 7 at the start of year 9.
Naturally with he height increase there's been a weight increase of around 3 stone. Is this normal?
If she's slowed down now/stopped growing taller will the weight slow down? (A stone of the 3 is from September).
She's not started her periods yet also so will she gain anymore height and with the height and weight increase are they likely to start soon?

Girls usually stop growing on average 2.5 years after they first period. So yes likely she will continue to grow. Shes probably approaching her first period and girls do tend to gain weight before then and while growing. Check her BMI if you’re worried or speak to the GP.

It's hard to say, but are you saying she's 13/14 and not started her periods?

I think that's still in the normal age range but it is at the upper end.

Some kids also do shoot up like weeds and the onset of puberty can make you hold onto weight, but if you're concerned you should talk to your GP about it.

BMI is fine.
Being the eldest just unsure if 3 stone for 7" of height increase is normal and if weight will slow down like height did?
Yes just 14 and no periods.

I'd get it on the GPs radar. She probably will start her periods soon, but if she's not started them by 15 you can go back and say she still hasn't started her periods.

They're bringing in a new rule where if you contact a GP about the same thing 3 times and the GP can't resolve it that they will refer to a specialist which is why I'd suggest getting it on the GPs radar, but the GP will likely reassure you at this stage that it isn't the average age range but it's still within the normal age range for periods.

Thanks, I wasn't too concerned about lack of periods. One of her friends didn't start until nearly 16. It was more the weight gain. Thinking about it though if it slows down now then she isn't overweight so we don't need to worry.

Might be worth having PCOS ruled out if she’s not having periods at 14 and weight gain has been rapid or unusual?

I would wait op. 14 is not unusual for periods. My dd was 14 last week and has just had her second period. She put on a lot of weight in the last year but I can see it is steadying on her now already now she has started.
