Why is My Boob Job Getting Smaller?

Unless you have lost weight in the past several months you noticed the change in your breasts, the only conceivable cause would be (bilateral) loss of implant volume. This cannot occur with silicone, so you must have saline, and have developed leaks and gradual deflation in both. Although this is rare, especially both at the same time, but it is possible. I have had several patients puncture their implants, hoping to get "free" new ones from the manufacturer. Each implant company carefully examines each "leaking" implant under the microscope, and can tell if an implant has a defect, gradual damage from flexing of the shell (more common in textured implants, and under-filled implants), or if it was punctured externally.

You need to go see your surgeon for examination and recommendation! Good luck!

if you have saline, it could be they have a leak.  Another alternative is weight loss, if you have lost weight, your breasts will get smaller too.  You need an in person evaluation.

I doubt you have deflation. Either you have lost some weight or sometimes saline implants lose a little bit of volume with time. this can be noticeable in a slim person. go see your surgeon
