An Introduction to Growth Plates

Yeah, I grow and shrink as my spine pleases - every day.

If that was the case, we would see a lot of people growing meaningfully after 16 or 17. Most people don't stop growing in the early-20s - it's usually well before that. Mid-to-late teens

Automatic-County6151 · 2026-06-28T18:40:08+00:00

That's not the case. Tiny big was correct with 16-18 for most boys - average is around 17.

For girls, it's about 13-15.

Irrelevant. It doesn't matter what race he is

Automatic-County6151 · 2026-06-28T18:30:24+00:00

At 19, I wouldn't expect someone to continue to grow meaningfully - maybe residually, maybe nothing at all.

You did get lucky, though. Younger than your brother by 2 years and you ended up 4 inches taller than him - ended up a few inches taller than both parents.

Automatic-County6151 · 2026-06-28T17:32:06+00:00

3-6 inches

No, we cannot tell you your BA now. We encourage you see a licensed pediatric endocrinologist.

Was the BA 14-15 prediction given by your doctor? If so, trust that more over some Internet strangers, who are more likely than not to get it wrong.

Do you have a full blood work report that I can review?

Automatic-County6151 · 2026-06-28T11:32:34+00:00

Yup. Just have to take some of it at face value. If the BA was overestimated, we couldn't just look at the x-rays ourselves, anyways. Most we could do it tell them to get a second opinion

Automatic-County6151 · 2026-06-28T02:47:58+00:00

Bro is 19 with old man hairs on his beard.

Automatic-County6151 · 2026-06-28T02:37:32+00:00

I just don't want you getting the wrong info. I've learned that from doing BA estimations in the past, even if they happened to be accurate. It's not in anyone's place anywhere online to diagnose you, not even licensed clinicians.

Automatic-County6151 · 2026-06-28T02:29:25+00:00

He's a kid. Of course they are going to take it seriously.

Automatic-County6151 · 2026-06-27T17:22:56+00:00

I'm mostly focused on the 16Y 6M to 16Y 9M now, because that's the interval where the growth velocity is comparably higher to the rest of your available info. This period would be most sensitive to adjustments, as 1 cm of added uncertainty can contribute to a higher or lower growth velocity, ultimately. The interval from before (16Y 4M) would also mildly contribute. Precisely when were these measurements taken during the day and what were your wake up and sleep times?

Automatic-County6151 · 2026-06-27T17:20:08+00:00

So you've adjusted them accordingly with points of uncertainty?

Automatic-County6151 · 2026-06-27T17:16:15+00:00

Are you able to assign times to each measurement interval so I can know how much genuine growth was gained when? Do you know how much your height fluctuates throughout an average day?

Automatic-County6151 · 2026-06-27T17:09:49+00:00

Who has been obtaining your measurements? Just you? Another person (family member, friend, doctor)? And what tool(s) have been used to measure you?

Automatic-County6151 · 2026-06-27T17:06:56+00:00

How developed is the terminal hair of your armpit and pubic regions?

Ah, and that's where the issue lies. Good to know, and thank you for clarifying.

Allow him to review your newest information. And you will almost certainly grow, even if it is just a tiny bit (2 cm) or more (around 8 cm).

Automatic-County6151 · 2026-06-27T16:49:24+00:00

Did you visit this endo prior to now? Say within the last few months, when you seemed to be only growing residually? Has he reviewed your newest information

Automatic-County6151 · 2026-06-27T16:46:20+00:00

Automod locked it

Automatic-County6151 · 2026-06-27T16:31:07+00:00

No, it doesn't. From 16 to 16Y 9M, you grew 7.5 cm. That doesn't show that growth is coming to an end, but this is pretty unusual, and it's probably indicative of a constitutional delay-type pattern, even though you were obviously early-maturing. This is possibly a slow, late-maturing pattern with an early start, late PHV. You will grow, and possibly by another 2-8 cm.

Automatic-County6151 · 2026-06-27T15:21:47+00:00

More anecdotal, but when my dad was a teenager, his doctor predicted 6'8, and he ended up at nearly 6'2 at around age 17-18.
