5'2", 125lb. 34G. What is a good size to reduce to?

Deciding exactly what size to go down to is very
much a personal issue. Everyone has a different idea of what the perfect breast
size is.Obviously, being a 34G, you
would benefit from a breast reduction.It will lessen your discomfort and make you much more mobile.I can only imagine how uncomfortable you must
be with your small frame and that large breast size.If you were my patient I would probably
suggest that you consider going down to a big C or small D cup.That way, we could remove enough tissue to
make you feel better, but not make you feel like you were too small.Also, there is a limit of how much tissue we
can take and still keep a healthy blood supply to the tissue left behind.A big C to small D will leave enough
perfusion to keep your tissue healthy and allow for safe healing.

The
most frequent complaint after breast reduction is disproportional small
breasts. At size 34 G each 100 grams of
tissue corresponds to 1 cup size change.
From this, you can compute the weight removal to achieve your desired
goal. I recommend a new technique called
The Ultimate Breast ReductionTM.
This technique avoids the ugly vertical scars of the traditional
technique, maintains nipple sensation and the ability to breast feed. Pain is relieved by transferring the weight
of the breast to the underlying muscle rather than excessive reduction. At age 49, lift is just as important as the
reduction. The Ultimate Breast ReductionTM
reshapes your breast tissue creating upper pole fullness, elevates them higher
on the chest wall and more medial to increase your cleavage. The final result is a beautiful breast that
looks more like an implant than a breast reduction. Best Wishes,Gary Horndeski, M.D.

Thank you for your question. Based on your description you may be an excellent candidate for breast reduction surgery; this operation tends to be one of the most patient pleasing operations we perform.
 I would suggest that you do your due diligence and select your plastic surgeon carefully. Ask to see lots of examples of their work helping patients similar to yourself.
 It will be very important for you to communicate your goals, concerns, and questions with your plastic surgeon. I would suggest that you write these down before your preoperative appointment.
In my practice, I ask patients to collect "goal  pictures”  of breasts which they like, breasts that are too big, and breasts that are too small as well.  I find that the use of pictures is more helpful than the words “natural” or "proportionate” etc., which can mean different things to different people. Discussing your goals in terms of cup size may be a source of miscommunication, since cup sizes will vary from one bra manufacturer to another.
Many of my patients choose to have enough breast tissue removed to help alleviate symptoms while retaining enough breast tissue to remain proportionate to the remainder of  bare torso. Again, preoperative communication will be critical.
 I hope this, and the attached link, helps.

Breast reduction will cause a better look and quality of life as you wont have a lot of weight in your chest, a discussion with your PS will guide you to the right cup size, for your height and weight maybe a C cup will fit you right. Good luck!

It sounds like you would benefit from a reduction. Without an exam it would be difficult to know how much tissue you would need removed or what your anatomy would dictate. Find a Board Certified Plastic Surgeon in your area and make an appointment to be evaluated. At that time he or she can review with you what the best options are for you and advise you on what outcomes you might expect. Good luck to you.
