By gaining a better understanding of the causes of gynecomastia and the available treatment options, men can take steps toward feeling confident and comfortable in their skin.

Gynecomastia can develop in new-borns, puberty boys, and older men as a result of regular changes in hormone levels, though other causes exist.

However, if the problem persists, medication or gynecomastia surgery may be necessary. Understanding the reasons behind gynecomastia can help you better manage the condition and reduce your risk of developing it.

An In-depth Look at the Causes of Gynecomastia 

Hormonal Imbalance 

One of the most common reasons for gynecomastia is hormonal imbalance. The human body needs a delicate balance of hormones to maintain proper functioning. When this balance is disturbed, it can lead to various health problems, including gynecomastia. In addition, multiple factors, including puberty, aging, hormonal disorders, and certain medications, can cause hormonal imbalances. Opt for male breast reduction surgery to address the condition of gynecomastia with the advice of a professional.


During puberty, testosterone and oestrogen levels in the body fluctuate, causing a hormonal imbalance. This can lead to temporary breast enlargement in some boys. However, in most cases, the condition resolves as hormone levels normalize. 


Men’s testosterone levels naturally decline as they age, causing a hormonal imbalance that can lead to gynecomastia. This common condition in older men is known as age-related gynecomastia. The cost of the surgery varies depending on factors such as the surgeon’s experience and location and the extent of the procedure.

Hormonal Disorders 

Hormonal disorders such as hypogonadism and hyperthyroidism can cause hormonal imbalances leading to gynecomastia. Hypogonadism occurs when the testes do not produce enough testosterone, whereas hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone. 


Certain medications can cause gynecomastia by disrupting the balance of hormones in the body. Some of the most prevalent medications that can cause gynecomastia include anabolic steroids, anti-androgens, antidepressants, and heart medications. 

Lifestyle Factors 

Lifestyle factors such as alcohol consumption, obesity, and drug use can also contribute to the development of gynecomastia. If you are looking for a solution to your gynecomastia, searching for ‘gynecomastia surgery near me’ may help you find a qualified plastic surgeon. 

Alcohol Consumption and drug use 

Alcohol consumption can cause hormonal imbalances that can lead to gynecomastia. Alcohol is known to decrease testosterone levels and increase oestrogen levels in the body. Drug use, especially marijuana, can cause hormonal imbalances leading to gynecomastia. Marijuana contains compounds that mimic oestrogen in the body, leading to breast enlargement in men. 


Obesity can cause hormonal imbalances that can lead to gynecomastia. Fat cells in the body produce oestrogen, which can cause breast enlargement in men. It is important to note that in some cases, the cause of gynecomastia may be unknown, and several factors may contribute to the condition. However, early diagnosis and treatment can help men manage the symptoms and improve their quality of life regardless of the reason. 

The Importance of Early Diagnosis and Treatment 

Early diagnosis and treatment of gynecomastia are crucial for managing the symptoms and improving quality of life. In addition, prompt treatment can help alleviate physical and emotional distress caused by the condition, as well as prevent further progression and complications.  

Early diagnosis also allows for a more comprehensive evaluation of the underlying cause, which can inform the most effective course of treatment. For example, switching to a different medication may be recommended if the reason is due to a medication. If the cause is due to a medical condition, treating the underlying disease can help resolve the symptoms of gynecomastia. It is advisable to consult with a board-certified plastic surgeon to discuss the gynecomastia surgery cost, expected outcome, and any potential risks and complications.

Bottom Line 

In conclusion, gynecomastia is a complex condition affecting millions of men and can profoundly impact their physical and emotional well-being. Unfortunately, many people are unaware of the causes and available treatment options despite its prevalence. However, by understanding the underlying causes, such as hormonal imbalances, medical conditions, and certain medications, men can take steps toward finding practical solutions. Whether through lifestyle changes, surgery, or medications, many options are available for treatment, such as gynecomastia surgery and regaining confidence in one’s appearance. 

Men need professional medical advice to determine their case’s best action. However, with the proper support and treatment, men can overcome the physical and emotional distress of gynecomastia and live happier, healthier life.
