Gynecomastia: Causes, Treatment, and More



Gynecomastia is a condition where male breast tissue enlarges and swells. This can result from an imbalance of estrogen and testosterone hormones. Or, it can be from certain medications or physical illnesses. It can cause physical and emotional discomfort, but treatments exist to help manage it.

We will look at what causes it, what the symptoms are, and what treatments are available:

Definition of Gynecomastia

Gynecomastia is an unusual enlargement of male bosom tissue. It can be in one or both boobs and it can affect one or more areas. It is most popular in teenage boys and older men. Up to 60% of males of any age can have it.

It is important to distinguish between gynecomastia and pseudogynecomastia. Pseudogynecomastia is an enlargement of male breast tissue due to fat deposits. Treatment is usually liposuction. But gynecomastia may resolve on its own with proper nutrition, exercise and reducing stress.

Causes of Gynecomastia

Gynecomastia is a medical issue where male breast tissue becomes enlarged and firm. It can affect one or both breasts and can affect men of any age. It is necessary to comprehend the causes of gynecomastia, to be successful in treating it.

The cause of gynecomastia can be an imbalance in hormones, such as when testosterone is too low and estrogen too high. This occurs naturally due to changes in hormones during adolescence or aging. But it can also happen due to medical issues that impact hormones, like an overactive thyroid or kidney disease. Plus, some medicines can change hormone levels and cause gynecomastia.

Sometimes the cause of the condition is unknown. However, certain lifestyle choices increase the risk of gynecomastia. These include drug use – marijuana and amphetamines – and drinking alcohol or eating heavily processed foods with preservatives and hormone-mimicking chemicals. Weight loss or gain over a short period of time can also lead to gynecomastia.

It's important to identify potential causes of gynecomastia before it gets more difficult to manage. Treatment should be tailored to each person's health history, lifestyle, and other factors connected to the development of the condition.


Gynecomastia is a condition that impacts both teens and grown-ups. The most common symptom is an enlargement or puffiness of breast tissue, with tenderness or sensitivity. Other accompanying signs may be swelling, itchiness of the skin, and discharge from the nipples.

In this article, we'll examine the usual symbols and indications of gynecomastia in greater detail:

  • Enlargement or puffiness of breast tissue.
  • Tenderness or sensitivity.
  • Swelling.
  • Itchiness of the skin.
  • Discharge from the nipples.

Common Symptoms of Gynecomastia

Gynecomastia is an enlargement of breast tissue in males that can happen at any age. Symptoms include:

  • A swelling under one or both nipples, which might be painful when touched.
  • Areola that are wider than normal (the dark circles around the nipple).
  • Breast tissue enlargement, often described as a lump under the nipple. It can be different for everyone and can affect one or both breasts.
  • Chest area pain that can be constant or on and off.
  • Nipple discharge (rare).

Different Types of Gynecomastia

Gynecomastia is usually caused by hormone imbalances. It has different types, from mild to severe. Juvenile gynecomastia is the most common and mild. It affects teenagers due to the hormone changes in puberty and usually disappears over time.

Pseudogynecomastia is caused by too much fat on the chest area. This can be improved with diet and exercise.

True gynecomastia develops when extra glandular tissue forms in a man's chest. It can be treated medically or surgically, depending on the severity.


Gynecomastia is a condition where male breasts are enlarged. Diagnosis involves physical examination and a review of the patient's medical history. Lab tests and imaging studies may also be needed for an exact diagnosis.

This article discusses the importance of accurate diagnosis and the tests used to diagnose gynecomastia:

Physical Examination

A physical exam is the first step to diagnose Gynecomastia. A physician will check for lumps or masses and note any changes in color or texture of the skin, nipple, or areola. The “Pectoralis Major Bimanual Compression” might be done to reveal new glandular formation.

Confirmation of Gynecomastia requires mammography or ultrasonography to rule out cancer or other abnormalities. MRI can provide info about fat deposits enlarging the breasts. Imaging needs to be done carefully, as results can help decide the treatment plan.

Imaging Tests

Imaging tests, such as ultrasounds and mammograms, can aid in diagnosing gynecomastia. They create pictures of the inside of the breast. This helps doctors distinguish between gynecomastia and male breast cancer. Mammograms can detect if glandular activity is higher than normal, but are usually not used on adults under 40. Ultrasound can show fluid buildup, which is a sign of gynecomastia. MRI scans are also used, when another cause is suspected or when more info is needed from an ultrasound.

Blood Tests

Blood tests can be of help. They can rule out causes of gynecomastia. These causes include metabolic, liver, or thyroid disorders. To check hormone levels, your doctor may order a blood test. This test will look for testosterone and estradiol (a form of estrogen).

Imaging scans, such as ultrasound or mammogram, may also be needed. This information helps your doctor diagnose the cause. Then, they can suggest treatment options.


Options for treating gynecomastia are extensive. Medication, surgery – multiple approaches are there to ease the signs of gynecomastia. We'll outline the various treatments and their accompanying risks in this section.


Medication is a usual treatment for gynecomastia, based on its type and severity. Hormone therapy is generally used, with SERMS and aromatase inhibitors doing the job of blocking hormones that make breast tissue expand. In some cases, anti-androgen meds are prescribed too. Surgery might be suggested for extreme cases, though most men can control their condition with medication.

Besides, changes in lifestyle, like eating well or reducing weight, could also help reduce symptoms of gynecomastia.


Gynecomastia surgery is one option for treating the condition. It involves removing excess glandular tissue, fat and/or skin from the chest. Surgery leaves a scar that may be hard to hide. It may be offered when other treatment options have failed or when the situation is severe and causing distress and discomfort.

The procedure usually uses general anesthesia and takes 1-3 hours, depending on the extent of the condition. Liposuction and excision techniques can reshape the male breast. The techniques used depend on the amount of fat, glandular tissue and skin looseness, as well as other factors.

Recovery time ranges from 1-4 weeks, depending on the procedure and healing process. Men can return to work and regular activities in a week. Swelling, tightness and soreness are normal, but decrease over time. Results are visible more quickly than with non-surgical treatments, but may take several months due to swelling post-op.

Lifestyle Changes

Gynecomastia may be triggered by weight gain, recreational drugs, alcohol, or medications. Making lifestyle changes can help stop it and reduce symptoms.

  • Exercise: Exercise can help by lowering body fat % and male hormone levels. It also controls weight and builds muscle.
  • Nutrition: Eating a balanced diet of whole grains, lean proteins, fruits, and veggies can help. Also, limiting salt helps too.
  • Reduce Stress: Relaxing and seeking help can reduce stress. This lets you focus on healthy habits like eating right and exercising.
  • Avoid Meds: Avoid anabolic steroids and other hormone-altering meds. Also, avoid BPA, marijuana, and alcohol. These raise estrogen levels and increase risk of gynecomastia.


Gynecomastia is a disorder in males when their breast tissue enlarges unusually. If not treated, this may have serious consequences for physical and mental health.

There are three potential risks – from the condition itself, from the treatment, or both. This article looks into the possible complications of gynecomastia. It helps to understand the dangers of this issue.

Possible Complications of Gynecomastia

Gynecomastia is an embarrassing matter and can bring down self-esteem. Usually, the physical pain and psychological distress connected to it will disappear over time. But if left untreated, more serious complications can arise. These include:

  1. Nipple Skin Irritation – Constant pressure from too much breast tissue can cause skin around the nipples to become itchy, sore and even bleed.
  2. Enlargement of Chest Tissue – Without treatment, the tissue in the chest area will grow abnormally. This can cause sagging skin that won't go away without surgery or steroid treatments, with risks.
  3. Testicular Atrophy – Gynecomastia can lead to testicles shrinking due to a hormone imbalance caused by too much estrogen. Seeing a doctor right away is important.
  4. Infertility – It can also cause low testosterone production, leading to impotence and lack of libido, and difficulty conceiving.

In rare cases, tumors can form in the breast tissue which must be taken care of by an oncologist, or it might turn life-threatening.

Long-Term Effects of Gynecomastia

Gynecomastia can be more than just a cosmetic issue. It could cause physical and mental risks that are hard to deal with.

  • Physical complications might include discomfort, tenderness, swelling, skin irritation, or changes in weight. In some cases, it may also lead to inflammation of the breast tissue or severe pain.
  • Psychologically, it could lead to depression, body dissatisfaction, and issues such as weak self-esteem. These effects can remain even after the physical appearance of the chest has improved. Professional treatment may be necessary to manage them.

Research shows those with gynecomastia are at higher risk for cancer, so regular check-ups are advised. It is also recommended to make lifestyle changes to optimize health after treatment, such as balanced dieting and exercising.


Gynecomastia is an enlarged male breast. It can happen to anyone and is caused by many things, like hormone changes, medicines, and illnesses. This can make people feel unhappy, so it's important to stop it from happening or getting worse.

To stop gynecomastia:

  • Don't take drugs, like steroids or marijuana.
  • Exercise and eat healthy to balance hormones.
  • Be aware of medicines that can mess with hormones, like heartburn meds or birth control pills.
  • Keep a healthy weight.
  • Reduce stress so cortisol is low.
  • Visit the doctor if you have signs of gynecomastia.


Gynecomastia is an enlarged chest in men, and this can have different causes. Like, hormone imbalances, medications, surgeries, or health conditions. Mostly, it can be treated with changes in lifestyle, medication, or surgery.

Lifestyle changes include exercise and dieting, but not always successful. Medications like aromatase inhibitors and 5-alpha reductase inhibitors may be prescribed, but these can have side effects.

Surgery is an extreme option if the other treatments don't work. There are two types of surgery for gynecomastia:

  • Liposuction removes excess fat cells in the chest area.
  • Excisional surgery removes glandular tissue from the chest wall underneath the nipple area.

Both of these procedures may leave scars, but they often provide better results than lifestyle changes alone.
