Can weight loss make gyno less noticeable

Patient: Hello I am 14 years old and have gyno. I have had it for over 2 years now. I am very subconscious and cannot have surgery because I am not old enough. I am not interested in waiting it out and I was just wondering is there any exercise such as weights or pushups that I can do to make it less noticeable

Symptoms: Puffy nipples
