What can I do to get smaller breast? Does the pills work?

There are no pills that can make your breasts smaller. Your options are: 1) weight loss2) Breast reduction 3) Liposuction Ensure you consult with a board certified plastic surgeon if you are considering surgery.

Reducing breast size can be done by losing weight, however if this is not an option then I'm afraid there is not other choice but surgery (breast reduction or liposuction). 

There is no pill I know to reduce breasts. I feel you have three options. One, if you are overweight then losing weight will also make your breast decrease in size. Second, liposuction of your breast could be done without general anesthesia, but this would not address the sag, nipple position, or excess skin. It is possible to have a standard breast reduction after a pulmonary embolism, but you would have to have permission from and support from your medical doctors. They would have to help you weigh the various risks. It is possible that they feel it is too high a risk at this time. Good luck.
