25, 181cm, 245cc, 62kg, are my nipples too high? If so, what is the cause and what can be done about it? (Photos)

I don’t think your nipples are too high. You have some bottoming out but you lack upper fullness because you have implants that are small. I would have used around 350 cc

Dear Leatomic.be,
bottoming out occurs when the implant falls below the current breast crease or inframammary line. It's more likely to happen with inframammary incisions, which is why I try not to use the inframammary approach to any breast surgery.
Bottoming out can also occur if an implant is too large for the breast pocket. That is why it is important to choose an implant size that's correct for your body. I perform numerous measurements in the office to determine optimal implant size for my patient's bodies.
If you are concerned, please check it with your plastic surgeon for reassurance and to further discuss your options and possibility of revision.

Your nipples are not too high, but your implants have dropped and bottomed out so they are sitting too low. Your lower pocket can be tightened, and you may need more support with an internal bra of mesh.

Your implants have bottomed out.
This is a reflection on how the procedure was done.
I suggest you follow up with your surgeon or have a few second opinion consultations.
To make an assessment we need to see proper before and after pictures. If you don’t have the pictures than ask your surgeon to forward the pictures they took. It’s also a good idea to get a copy of your operative report. It would be good to know if your implants are sub-pectoral or sub-glandular.
Best,
