My brother smells a lot worse than I think someone his age should...?

My little brother, who is 10 years old, smells HORRIBLE. I don't mean to be mean, but he really does. It's sort of embarrasing around others (it's a sweat problem), especially because it was his kindergarten teacher who pointed it out, about five years ago. Is this normal? Because at age five, he smelled like 16 year old boys after gym class. He's not hairy or anything, so I'm scared he has a gland problem. I don't know any names of these types of problems, and my dad refuses to get help, unless we can figure if there is, in fact something wrong. He has to be closely monitered when he showers, to make sure he gets the stench out, and he must always where deoderant and cologne, so not to bother anyone. I'm not sure if a sweat problem can be dangerous or not which is why I'm worried about him. Can someone tell me, based on the information, if he has some sort of problem or disease?

Thanks for some answers, but no, he is not overweight. He's actually very fit for his age.

Is he overweight? Has anyone mentioned this to his Dr. during regular physicals? I was going to mention precocious puberty, but you said that he was not showing any signs of puberty.
Hi, checked back...
there is a condition of having overactive sweat glands.. the smell from sweat is caused by bacteria. He probably needs a prescription antiperspirant, which he will have to get from the doctor. Also if his skin is oily already, he will need to bathe frequently (morning, after gym and at night)... the oil mixing with the extra sweat will make his b.o. almost unbearable.
It really should be addressed at his annual physical. You are a really good brother to look out for him like this!
