Suggest Treatment For Gynecomastia

Hi there... I'm 25 years old, male and have rather large manboobs. Though, doing some research, I've come across thinking it may be gynecomastia. Other details; I am overweight. I weigh 65kg (without clothes), . I'm trying to lose some weight this year, I'm eating healthier and am eating a less than I used to.please give me some medical advice and maybe some tips for helping me get rid of them. Please help out, they are very embarrassing and make me feel very self-conscious. i don't wanna go through surgery. is there any medicine available in the market ?
