What Causes Gynecomastia?

Gynecomastia affects countless men across the UK, impacting not just appearance but self-confidence and overall well-being. But what causes gynecomastia, and why does it happen? At Jorja Aesthetics, we believe in honest, medically accurate answers and patient-first care.

Getting Real: What Causes Gynecomastia?

‍
Gynecomastia occurs when there is an imbalance between the hormones oestrogen and testosterone in the male body. Contrary to the common misconception that it’s solely a result of weight gain or lack of exercise, gynecomastia can affect individuals of all body types—including those who are slim and otherwise healthy. Here's a closer look at some of the key causes:

1. Hormonal Changes:

During different life phases—such as puberty, middle age, or even later adulthood—natural fluctuations in hormones can increase oestrogen levels relative to testosterone. These shifts prompt the development of glandular breast tissue.

2. Medications and Medical Conditions:

Certain medications can lead to gynecomastia, including some anti-anxiety drugs, antidepressants, heart medications (like calcium channel blockers), and treatments for ulcers. Health issues such as liver or kidney disease, thyroid imbalances, and tumours (especially those that affect hormone production) may also contribute.

3. Lifestyle and Substances:

The use of anabolic steroids, excessive alcohol consumption, cannabis and some herbal products containing phytoestrogens have all been linked to hormonal disturbance and gynecomastia. Illicit substances, such as amphetamines and opioids, can also disrupt hormone levels.

4. Ageing and Body Composition:

As men age, their testosterone naturally declines while body fat tends to increase. Since fat cells contribute to oestrogen production, older men are more prone to developing gynecomastia—even if their overall lifestyle hasn’t changed.

Gynecomastia vs. Pseudogynecomastia: Busting the Myths  

Not all enlarged male chests are caused by glandular tissue. Sometimes, excess fat alone (without gland development) mimics gynecomastia—a condition termed pseudogynecomastia. True gynecomastia involves firm tissue beneath the nipple, while pseudogynecomastia is just fat. At Jorja Aesthetics, our thorough assessments help distinguish between the two, so your treatment plan is laser-focused and honest.

Why Does It Matter? Beyond Aesthetics—Your Confidence, Your Health  

The effects of gynecomastia go far beyond the physical. Many of our patients tell us it impacts how they feel in clothes, their willingness to exercise, and sometimes even relationships. It’s essential to stress that gynecomastia is not a sign of weakness, poor discipline, or “something to hide”—it’s a medical condition rooted in biochemistry. That’s why, at Jorja Aesthetics, we believe informed, judgment-free care is the only way forward.
