I'm concerned about gynecomastia.

The one who is 고민 is not me, but my older brother.. Actually, in a way, he's male, but sometimes he feels like he needs to wear women's underwear.

There are some cases where the chest is more developed... my older brother is like that.

I thought so too, but maybe it was because I gained weight. After successfully dieting and exercising, I was able to fit into clothes and now I go out confidently. My older brother finished his diet, but he's still worried because his chest didn't shrink. Seeing him always wear loose-fitting clothes and not being able to wear tight summer T-shirts makes me a little concerned.

I've seen a lot of advertisements related to gynecomastia, but I haven't looked into it in detail. I'm curious whether it can be treated with a simple procedure or if surgery is required separately.
