Causes of Gynecomastia

Serving Chesterfield, O'Fallon, St. Charles and Nearby Areas of St. Louis

Gynecomastia means “woman-like breasts” and can be a tremendously embarrassing condition for men. While sometimes related to weight gain, gynecomastia can occur in men of all shapes and sizes. If you are currently struggling with this condition, please contact Richard L. Kofkoff, MD, PC online or by calling our Chesterfield, Missouri office at (636) 532-1717 to schedule a male breast reduction consultation.

Hormone Imbalance

Gynecomastia can be caused by hormone imbalance in infants, growing boys, and even adult men. Relatively common among adolescent boys, in this younger age group gynecomastia tends to self-correct. In older men however this condition may not so easily correct itself, making male breast reduction the most effective option.

Dr. Kofkoff offers customized gynecomastia treatment to men living in and around St. Louis. If you are struggling with this condition, Dr. Kofkoff can meet with you to determine its cause and build a male breast reduction procedure that addresses your specific needs.


In addition to hormone imbalance, gynecomastia may result from the use of prescription medications and medical treatments including:

  • AIDS medications
  • Anabolic steroids
  • Antiandrogens
  • Antianxiety medications
  • Antibiotics
  • Chemotherapy
  • Heart medications
  • Ulcer medications

Alcohol and some illicit drugs are linked to gynecomastia as well. These include methamphetamines, heroin, and marijuana. If you currently use drugs or alcohol, you will need to quit in order to be a good candidate for male breast reduction surgery.

During your gynecomastia consultation at our Chesterfield office Dr. Kofkoff will review your current medications to determine if modifications will be needed for lasting results.

Health Conditions

Several health conditions can contribute to gynecomastia. Some of the most common are:

  • Hypogonadism
  • Hyperthyroidism
  • Kidney failure
  • Liver failure and cirrhosis
  • Tumors

The process of aging can also be a contributing factor, though risks reduce when healthy lifestyle choices are made. In fact, healthy lifestyle choices can go a long way in helping prevent gynecomastia and in assisting in the maintenance of your male breast reduction surgery. Eating a well-balanced diet, avoiding sugary and processed foods, and getting at least three hours of moderate exercise every week will be essential following your procedure to help ensure lasting results.
