What Causes Gynecomastia in Men? Reasons & Risk Factors

Gynecomastia is a condition that causes the enlargement of breast tissue in men, often leading to discomfort, embarrassment, and emotional stress. While many people mistake it for mere fat accumulation, true gynecomastia is caused by a hormonal imbalance or other underlying health issues. Understanding the causes of gynecomastia in males is crucial not only for effective treatment but also for prevention. At Orange Tree Health in Delhi, we emphasize early diagnosis and offer advanced gynecomastia treatment without surgery for eligible candidates.

Let’s explore what leads to gynecomastia and how non-surgical options can help you regain your confidence.

Gynecomastia & Its Symptoms?

Gynecomastia is the medical term for the enlargement of breast gland tissue in boys or men. It can affect one or both breasts and sometimes presents unevenly. Unlike pseudogynecomastia (which is fat buildup due to obesity), true gynecomastia involves firm or rubbery glandular tissue underneath the nipple. 

Common symptoms of gynecomastia are:

  • Swollen breast gland tissue.
  • Breast tenderness or sensitivity.
  • Nipple discharge in rare cases.
  • Emotional distress or body-image issues.

This condition can occur at any age but is especially common during puberty, middle age, and older adulthood.

Most Common Causes of Gynecomastia in Males

Understanding the causes of gynecomastia in males is the first step toward selecting the right treatment approach. Here are the primary culprits:

1. Hormonal Imbalance in Body

The most common cause is an imbalance between two key hormones, testosterone and estrogen. While testosterone controls male traits, estrogen, though typically in small amounts, can stimulate breast tissue. When estrogen levels become too high or testosterone drops, gynecomastia may develop. This hormonal shift may occur:

  • During puberty.
  • In aging men due to natural hormone decline.
  • After certain illnesses or surgeries involving the testes.

2. Certain Medications

Some commonly used medications can disrupt the hormonal balance. These include:

  • Anti-androgens (used for prostate enlargement or cancer).
  • Anabolic steroids and androgens.
  • Certain antidepressants and antipsychotics.
  • Heart medications (like calcium channel blockers).
  • Ulcer medications such as cimetidine.
  • Chemotherapy drugs.

3. Some Health Conditions

Several underlying conditions can also be responsible: 

  • Liver disease: The liver helps regulate hormone metabolism. Liver dysfunction can lead to increased estrogen levels.
  • Kidney failure: Long-term dialysis affects hormonal levels.
  • Thyroid disorders: Overactive thyroid (hyperthyroidism) can boost estrogen production.
  • Tumors: Rarely, tumors in the testes, adrenal glands, or pituitary gland may alter hormone levels and cause breast tissue growth.

4. Harmful or Intoxicating Substance Use

Certain recreational substances are strongly associated with gynecomastia:

  • Alcohol
  • Marijuana
  • Heroin
  • Methadone
  • Amphetamines
  • Anabolic steroids (commonly misused in gyms).

5. Excessive Fat & Obesity

Excess fat doesn’t just accumulate in the chest area: it also increases estrogen production due to fat tissue converting testosterone to estrogen. This creates a hormonal imbalance that promotes gynecomastia.

6. Genetic or Congenital Conditions

Genetic syndromes like Klinefelter syndrome, which results in low testosterone and high estrogen levels, can lead to gynecomastia from adolescence. Such cases are very rare but can happen and often need specialized medical management.

Risk Factors You Shouldn’t Ignore

While the causes are rooted in biology, some risk factors increase the likelihood of developing gynecomastia:

  • Age: Teenagers (due to puberty) and older men (due to testosterone drop).
  • Medications: Especially long-term use of hormone-altering drugs.
  • Recreational drug use.
  • Obesity and poor lifestyle habits.
  • Underlying health conditions (liver, kidney, thyroid disorders).
  • Family history of hormonal or genetic disorders.

At Orange Tree Health, we evaluate each case to uncover the exact cause and risk profile before suggesting a treatment plan.

Can Gynecomastia Go Away on Its Own?

In some cases, YES. However, if breast enlargement persists for more than a year or causes significant discomfort, it’s advisable to seek medical attention.

  • Pubertal gynecomastia often resolves on its own within 6 months to 2 years as hormone levels stabilize.
  • Mild obesity-related cases may improve with lifestyle changes like weight loss, exercise, and dietary control.

Gynecomastia Treatment Without Surgery

Many individuals want to avoid surgery, and the good news is, gynecomastia treatment without surgery is a real and viable option in many cases. At Orange Tree Health, we specialize in holistic and medical approaches that focus on treating the root cause.

1. Lifestyle Modifications

  • Exercise & Weight Loss: Cardio and strength training reduce body fat and improve testosterone levels naturally.
  • Dietary Changes: Reducing processed foods and sugar while increasing healthy fats and proteins supports hormonal health.
  • Avoiding Triggers: Eliminating alcohol, marijuana, and steroids is crucial in preventing further breast enlargement.

2. Hormone Therapy

If tests reveal hormonal imbalance (like low testosterone), hormone therapy may be recommended under expert supervision. This could involve:

  • Testosterone replacement therapy (TRT).
  • Aromatase inhibitors to prevent conversion of testosterone into estrogen.

Note: Hormone therapy should never be self-administered. It requires continuous monitoring.

3. Medical Management

Certain medications can help reduce breast tissue:

  • Tamoxifen (a selective estrogen receptor modulator): Often prescribed for painful gynecomastia or visible enlargement.
  • Clomiphene citrate: Encourages testosterone production.
  • Anastrozole: An aromatase inhibitor that limits estrogen levels.

These are most effective in the early stages and are prescribed based on individual hormone panels and medical history.

4. Compression Garments

While not curative, specially designed vests or compression shirts can help flatten the chest and improve confidence in social settings. They’re also useful during weight loss or ongoing treatment.

5. Nutritional Supplements (With Caution)

Some patients explore supplements like zinc, vitamin D, and herbal boosters. While these may support general hormone health, they’re not a substitute for medical treatment and should only be taken after consulting a specialist.

When to Consider Surgery (Optional)

Surgery becomes an option when:

  • Gynecomastia has lasted more than 12–24 months and hasn’t responded to other treatments.
  • The tissue is dense and fibrotic (less likely to shrink with medication).
  • Psychological distress is severe, and quality of life is impacted.

At Orange Tree Health, we evaluate each case carefully to see if gynecomastia treatment without surgery is still possible before referring to surgical options.

Gynecomastia Prevention Tips and Lifestyle Advice

  • Maintain a healthy body weight.
  • Exercise regularly (including strength training).
  • Avoid anabolic steroids and recreational drugs.
  • Review your medications annually with a doctor.
  • Get regular checkups for liver, kidney, and thyroid health.

If you notice any unusual breast changes, early consultation with a qualified doctor can help you prevent progression.

Understanding the causes of gynecomastia in males helps you take informed steps toward reversal and prevention.
