California's Top Gynecomastia Expert

Voted "Best Plastic Surgeon" 2016-2020 by San Francisco Magazine


Gynecomastia is a common condition that causes men to develop abnormally large and protruding breasts. In many cases, the breasts can resemble female breasts, which can lead to embarrassment and self-consciousness. Male breast enlargement is a combination of fat and breast tissue caused by an imbalance of hormones.

Serving patients in Walnut Creek, gynecomastia surgeries are performed by Dr. Delgado, one of the country’s leading physicians in treating enlarged male breasts. He often talks to patients who read online about the condition and come to his office with misconceptions about diagnosis and treatment. Dr. Delgado created this page to make sure you are well informed before meeting a surgeon.

  1. Eating soy or drinking soy milk can cause gynecomastia. Soy milk and soy products contain genistein and daidzein, two natural drugs that act similarly to estrogen. When consumed in high quantities, these drugs may cause breast enlargement in men. Studies have shown that even in minor doses, these natural drugs still potentially upset the male hormonal balance.
  2. Individuals who do not have a family history of gynecomastia can develop it. Even if someone does not have the genetic predisposition for gynecomastia, they can still be a victim of it later in life. Consumption of harmful drugs like marijuana and many medications, as well as specific illnesses, can also cause gynecomastia.
  3. Regular physical activity can get rid of gynecomastia. Even though exercising has many benefits when it comes to losing fat, it is not a treatment for gynecomastia. In Walnut Creek,
  4. Teen and adult men are often physically active in gyms and outdoors. People who suffer from ‘man boobs’ can try workouts that supposed to address chest fat, but the results are limited, and exercise cannot remove breast tissue once formed.
  5. Not all men with large, saggy breasts have gynecomastia. Large breasts in men can be caused by being obese (this is called pseudogynecomastia). Therefore, unlike the previous myth, men suffering from pseudogynecomastia can treat their enlarged breasts by losing weight.
  6. Male breast enlargement affects men of all ages. Human beings go through hormonal changes right after birth, while passing through puberty and old age. Changes in estrogen and testosterone levels in the early periods of life can lead infants and young boys to develop breasts.
  7. Not everyone with gynecomastia requires surgery. As stated earlier, boys going through puberty can develop large, swollen breasts due to hormonal changes. However, this is not necessarily a cause for concern. As these boys pass through adolescence, it is more than likely that their breasts will return to normal shape and size in about six months and up to two years – without any need for medical intervention.
  8. Not all gynecomastia cases require liposuction. Different men will have different degrees of breast enlargement. Male breast enlargement is classified into 4 grades. Dr. Delgado may perform liposuction on patients with pseudogynecomastia. While some men may benefit from liposuction only, others with excess skin may need to undergo a secondary procedure. If you are not sure about your particular case, Miguel Delgado M.D. will be able to determine the best option.
  9. Gynecomastia can affect one breast only. Gynecomastia can affect only one breast at a time, or it may cause both breasts to enlarge simultaneously. Only one breast being affected is called asymmetrical gynecomastia.
  10. Gynecomastia cannot be prevented. Hormonal elevation and hormonal imbalance cannot be prevented, but patients can take some steps to reduce their risk of gynecomastia. Walnut Creek residents and other Bay Area patients, who have a family history of it should take appropriate steps to avoid certain medications, be overweight, drink excess alcohol, and take drugs. It may help younger patients to take medicines prescribed by an endocrinologist. Even with these precautions, patients can still get gynecomastia.
  11. Gynecomastia will not lead to breast cancer. Many people are not aware of the fact that men can also have breast cancer. However, while gynecomastia and male breast cancer both enlarge the size of the breasts, they are still two different and unrelated illnesses.

Miguel Delgado M.D. possesses years of experience in diagnosing and treating all kinds of gynecomastia. If you think you are a victim of this condition, please book your consultation with him to be evaluated correctly in a private setting and be offered a treatment plan.
