Most people go through the operation without any complications, but there are risks associated with any form of surgery, and male breast reduction is no exception. No matter how small the operation it carries with it certain risks related to the anaesthetic, such as heart and lung problems, but with modern medical techniques the risks are very rare. Bleeding and infection can take place after surgery, and alteration in nipple sensitivity can sometimes occur after male breast reduction surgery. This could mean either hypersensitivity or decreased feeling in the nipples, which can either be temporary or permanent. But again, these side effects are very rare.
In some patients, scars can be lumpy and red for several months, although they should eventually fade to your natural skin colour over time. Rarely, you may also be left with nipples that aren’t symmetrical if a large amount of tissue has been removed and skin excised.
