AIBU to worry about delayed puberty in my 14-year-old son?

My oldest is 14 now and
there still hasn’t been any signs of puberty physically or mentally. He still likes things and acts like boys a few years younger which means he’s been struggling a bit in school socially with peers. Overall he’s amazing but I just worry if this is normal or not. I’m a single mum and I don’t know much about boy stuff regretfully (I know I need to learn). He does have type 1 diabetes and I was wondering if that causes a delay in puberty?

I would think a trip to the GP is in order

I agree to get him checked out but also most of my son’s class still act younger, I think Covid timing might have been a contributor. Saying that yes agree go to the gp but don’t see it as a negative thing that he likes younger things, people like different things

Is it something urgent?

What is his height and weight like?

Pinkflamingo10 · 13/09/2026 09:41

I’d ring your GP next week to arrange a face to face appointment to discuss everything.

HoraceCope · 13/09/2026 09:41

i dont think it is urgent but GP/endocrine sound useful

HoraceCope · 13/09/2026 09:42

can you check with his diabetic nurse?

Thisismyusernamehistory2 · 13/09/2026 09:42

Depends what you mean by major signs? Mine got taller but no facial or underarm hair till they were more than 14. All kicked in then but it was more gradual than dramatic

Holeymoley28 · 13/09/2026 09:42

Take him in for a check up as it’s not overall normal and good to get the ball rolling.

I wouldn’t delay going but I also wouldn’t request an urgent appointment.

Whoddathoughtit · 13/09/2026 09:43

Aww OP, he’s not in danger of being unwell so don’t panic but yes get him to the GP for a check over, there are some conditions that block hormone development but he might well just be a late bloomer. My nephew was the same at that age, all tests came back fine, he was nearly 16 really when puberty kicked in properly for him and he’s the same as his peers now but it’s worth ruling things out.
is he small for his age?

FayeLP · 13/09/2026 09:44

Type 1 diabetes can delay puberty, most commonly if blood sugar isn’t being managed consistently (no error on your part, it becomes more difficult for teens because of hormone shifts). I would put a call in to your diabetes nurse.

LarryForPrimeMinister · 13/09/2026 09:57

My son has type one hes ten and started already so its not a type one thing unless his blood sugars are constantly high?

LarryForPrimeMinister · 13/09/2026 09:58

Also, nout wrong with liking things younger than him thats just his personality!

x2boys · 13/09/2026 09:58

A bit different but i have a disabled 16 year old son who is very small for his age i was getting concerned as he wasent showing any signs of puberrty
But its all kicked in the last year or do hes also growing and eating me out of house and home!

somanychristmaslights · 13/09/2026 10:00

Why have you not spoken to a GP??

Namenamchange · 13/09/2026 10:01

I don’t know about the diabetes part, however, my son was 14, no signs of puberty went to bed one day and it as like overnight he changed. His whole body changed in a matter of weeks. I was so worried about him. He still not as tall as I think he should be, but I’m hoping that will come. But yes try the gp first

Balloonhearts · 13/09/2026 10:07

Any signs at all? Underarm or pubic hair? Voice changes or body odour? If not then I'd say GP visit. It's not an emergency but does need looking into at this point.

ExpressCheckout · 13/09/2026 10:18

He's at the later end of normal, OP, so please don't worry unless there's something definitive to worry about. Puberty ages are getting lower and this wouldn't be that uncommon a couple of decades ago.

Make an appointment with the GP. Bear in mind how embarrassed 14 year olds can be and offer to pop out during the examination if a suitable chaperone is available at the GP surgery - obviously you'll need stay with him if not!

As others have said, also a good time to check on diabetes control, HbA1c etc. as he approaches puberty. If he has a sudden growth spurt, you'll need to help him to keep an even closer eye on his diet, insulin etc.

My GP were brilliant when I questioned delayed puberty. After 14 is the NHS boundary for delayed puberty. We saw a GP, had a bone age x-ray appointment within a month, an appointment with a pediatrician at the hospital (with blood tests, etc.) within 3 months. The doctor said there were subtle signs (perhaps TMI, but he measured the size of his testicles!) that we wouldn’t necessarily notice and he was happy that puberty was about to start. He offered him testerone shots to ‘jump start’ the process, if it would help him mentally (e.g. self-esteem, bullying, etc.), but said that the evidence suggests that final height can be reduced by a cm or two if you take them (I’m a bit skeptical about this statistic…) and my son decided he was happy to wait - he’d got used to being much smaller than the others and they’d mostly stopped commenting. He had a follow-up 6 months later and everything was going as expected, just tracking a couple of years behind ‘normal’. The doctor said he’d probably just stop growing a couple of years later than everyone else, so it’ll not make any difference. Obviously, if your son’s blood tests suggested there was an issue then they’d behave differently but I felt like it was all taken very seriously and we weren’t fobbed off at any point.

My son didn't enter puberty until 14, he is now a 6"3 hairy big 18 yr old. I honestly think he will be fine but go to the GP to get him checked.

LathkillDale · 13/09/2026 10:37

I took DS at 18, when there no signs of puberty. We saw an endocrinologist, who ordered a wrist x ray and then prescribed testosterone injections. He said it was better to limit DS’ height, as he was going to end up 6’7” otherwise. It kick started puberty and DS is 6’4” - which imo is better.

Just because your T1D 10 yo son has started puberty doesn’t mean that T1D doesn’t affect onset of puberty in the restate of the T1D population - just that it didn’t in your son.

WestieW7 · 13/09/2026 11:26

Obviously if you are concerned you should see a GP but as anecdotal evidence my son was shorter than me when he was sixteen (I'm just under 5' 4") with a chubby hairless face. In the space of a year he shot up several inches. He's now a 5' 10" hairy burly man.
