7 year old with B.O

[EmBeEmBe]

I'm after some advice. My daughter, just 7, has increasingly bad B.O. We've noticed for a while but it used to be just after a warm day full if activity but now its every day despite the cold and the fact she's not doing enough exercise. She definitely smells worse in synthetic materials so I'm slowly removing them and replacing with only cotton. I wash her armpits every night with soap. I think its perhaps time for a deodorant. I use mitchum unperfumed. Do you think that would be ok? Or should I be seeking medic advice? Many thanks.

I would seek medical advice, there could be an underlying cause for it. 7 is quite young for B.O I'd say.

Yes definitely. We are being tested for this at the moment. Basically benign adrenal hyperplasia.
Early onset of adenarche (as opposed to puberty). You need an paediatric endocrinologist referral from GP
