What Causes Gynecomastia in Men?

October 22, 2025

Gynecomastia is a common condition where men develop enlarged breast tissue. It can affect one or both sides of the chest and often causes discomfort or embarrassment. But what actually causes gynecomastia in men? Let’s understand it in simple terms.

1. Hormonal Imbalance

The most common reason behind gynecomastia is an imbalance between the hormones estrogen and testosterone.

Estrogen promotes breast tissue growth.
Testosterone controls male traits and muscle mass.
When estrogen levels rise or testosterone levels drop, the breast tissue starts to grow.
This can happen naturally during puberty or aging.

2. Certain Medications

Some medicines can trigger gynecomastia as a side effect.
These include:

Steroids or anabolic drugs
Anti-androgen medicines used for prostate issues
Some antidepressants and heart medications
Drugs for ulcers or chemotherapy

If you are taking any long-term medication, consult your doctor before stopping or changing it.

3. Lifestyle and Substance Use

Substance use is another major cause.

Alcohol, marijuana, amphetamines, and steroids can all disturb hormone levels.
Maintaining a healthy lifestyle can reduce your risk and help manage the condition better.

4. Health Conditions

Certain medical conditions may also lead to gynecomastia, such as:

Obesity (fat tissues increase estrogen levels)
Liver or kidney problems
Thyroid disorders
Tumors affecting hormone-producing glands

5. Natural Changes with Age

As men get older, testosterone levels drop, and body fat increases. This change can lead to mild gynecomastia, which sometimes improves with exercise and a healthy diet.
