What is Macromastia (or Abnormally Large Breasts)?

What is considered abnormally large breasts?

The medical definition of abnormally large breasts (macromastia) is a condition where a woman’s breasts are excessively large, disproportionate to their body size, and can cause physical discomfort, pain, and social, psychological, or functional problems. There is no exact measurement for what is considered abnormally large, but typically breasts weighing over 5 pounds each, with a bra cup size of D or larger. It is a personal and subjective condition, and what may be considered abnormally large for one person may not be the case for another.


Breast size is primarily determined by the amount of glandular tissue and fat in the breasts. These are some of the causes that can affect breast size:

  • Hormonal changes, such as those that occur during puberty, pregnancy, and menopause.
  • Genetics also play a role in determining breast size and shape.
  • Some medical conditions, such as hormonal imbalance.
  • Certain medications, such as hormonal contraceptives and hormone replacement therapy.
  • Obesity can also contribute to larger breasts, as excess body fat can accumulate in the breasts.

What problems do large breasts cause?

  • Physical effects

The physical effects of large breasts can be significant. For many women, large breasts can cause back and neck pain, as well as skin irritation. Bra straps can dig into the skin and leave marks or indentations. In some cases, women with large breasts may also experience difficulty finding clothes that fit properly. 

  • Emotional effects

It’s no secret that breasts are often seen as a symbol of femininity and attractiveness. So it’s no surprise that many women feel self-conscious or even embarrassed about their breasts if they are larger than average. Many women who have large breasts feel like they are constantly being stared at or judged. They may feel like they need to hide their breasts, or wear loose, baggy clothing to try and disguise them. Some women may even avoid physical activity altogether because they are afraid of how their breasts will look or feel. 

Breast Reduction Surgery

Breast reduction surgery can help a woman achieve her desired breast size and alleviate any physical discomfort she may be experiencing. The surgery involves removing excess skin, fat, and tissue from the breasts. The size of the breasts is then reduced, and the remaining tissue is reshaped to create a more aesthetically pleasing appearance. If you are considering breast reduction surgery, it is important to consult with a board-certified plastic surgeon. During your consultation, your surgeon will evaluate your medical history and perform a physical examination. He or she will also discuss your goals and expectations for the surgery. Once your surgeon has all of the necessary information, he or she will be able to develop a treatment plan that is tailored to your specific needs.

Common problems after Breast Reduction surgery 

Here are some of the common problems that may occur:

  1. Pain and discomfort: Swelling, tenderness, and general discomfort are normal after breast reduction surgery, but severe pain and discomfort should be reported to a doctor.
  2. Infection: As with any surgical procedure, infection is a possible complication of breast reduction surgery. 
  3. Hematoma: A hematoma is a collection of blood that can occur after surgery, causing swelling and discomfort. 
  4. Numbness: Some temporary numbness or loss of sensation in the breast and nipples is common after breast reduction surgery.
  5. Asymmetry: It is possible for the breasts to become asymmetrical after breast reduction surgery.

With any surgery, there are risks. It’s important to discuss the potential risks and complications of breast reduction surgery with a qualified surgeon before undergoing the procedure. Regular follow-up appointments with the surgeon and proper aftercare can help minimize the risks and ensure a successful outcome. At GEM Clinic, we have qualified surgeons that will help you to get the best outcome possible. 

Is a Breast Lift better than a Breast Reduction? 

A breast lift is a surgical procedure that elevates the breasts by removing excess skin and tightening the surrounding tissue to reshape and support the new breast contour. A breast reduction does all of this, plus it removes breast tissue and skin to make the breasts smaller, lighter and firmer. It’s often done to alleviate back, neck and shoulder pain caused by the weight of large breasts.

Most women who opt for a breast lift are happy with their decision, but there are a few things to keep in mind before surgery. First, a breast lift will not significantly change the size of your breasts. If you want to reduce breast size, you’ll need to combine a lift with breast reduction surgery. Second, a breast lift will not correct significantly drooping breasts. If your breasts are very saggy, you may need a breast lift with implants. If you’re considering a breast lift, the best way to learn more is to consult with a board- certified plastic surgeon. He or she can answer your questions, assess your individual needs and help you decide if a breast lift is right for you.
