36G --> If 500 Grams is Removed, What Size Will I Be? I Prefer to Be a 36D or 36DD (photo)

I am going to be honest here. I think you want to have your cake and eat it, too. You want to have an insurance company pay for an operation, ostensibly because your breasts are too large and painful, but then have an aesthetic goal of remaining a DD. I perform breast reductions all the time on patients who have DD cup breasts and they have neck, shoulder and back pain, bra strap grooving and intertrigo. You will continue to have these problems if you do not reduce the breasts appropriately to alleviate them and I can assure you that no insurance company, at this time, will pay for a second reduction. You have a lot of sagging or ptosis and 500 grams will not produce a sufficient reduction from the larger breast. I would encourage you to go smaller than a DD and preferably to a large C/small D at your age because you can expect to gain weight with the years and for the breasts to enlarge as a consequence. Additionally, if the breasts remain too large, the effects of gravity will produce sagging over time.

Your photo demonstrates a roughly G cup right breast and a left breast that is one half to one full cup size smaller.  In order to obtain symmetry and satisfy your insurance company, 500 gms will need to be removed from the left breast and 600-700 gms will need to be removed from the right.  (Total breast tissue removed at least 1000 gms.)  I would estimate that this will leave you in the D cup range.  This should be more than enough to still look "busty" while still removing enough breast tissue to provide relief of symptoms.
