[Gynecomastia] Can gynecomastia develop when you reach your 30s and gain weight?

Hello. This is AB Plastic Surgery.

I’m writing this post to provide accurate medical information about gynecomastia.

In previous posts,

we looked at the diagnosis and treatment of gynecomastia (= male breast enlargement, gynecomastia), which refers to excessive enlargement of the male breasts.

Many people have been wondering whether gynecomastia can develop as they gain weight.

To put it simply, yes, gynecomastia can develop as you gain weight.

In other words, obesity is one of the causes of gynecomastia!

☞ Our body has various enzymes, and when certain enzymes increase, certain symptoms or diseases can occur.

Among the enzymes related to gynecomastia is an enzyme called aromatase.

Even male patients in their teens and twenties who had a good physique with no gynecomastia at all

can develop gynecomastia if, in their 30s, they gain weight and become obese, causing aromatase to increase and become activated.

☞ So, while this may sound obvious,

for patients with obesity, controlling the degree of obesity through diet and exercise is also important for treating gynecomastia.

I hope this helps men who are troubled by gynecomastia.

Thank you.
