When people begin researching DIEP flap breast reconstruction, one of the most common — and often quietest — questions they ask is:
“What are the risks and complications of DIEP flap surgery?”
This is a reasonable question. Any surgery comes with risks, and understanding them clearly — without alarm or minimization — is an important part of feeling informed and empowered.
This guide walks through the potential risks of DIEP flap surgery, how often they occur, and how experienced surgical teams work to reduce them.

This does not mean DIEP flap reconstruction isn’t possible — only that experience and careful evaluation matter even more.
