Can surgery for gynecomastia and any of it's possible complications be life threatening?

Complications afer cosmetic surgery such as bleeding, infection, numbness, and bad scars should be uncommon when performed by experienced surgeons. All together the occurence of these complications should be less than 1-2%. Life threatening complications such as heart attack stroke and blood clots should be even much less. it is important that your surgeon understands your complete medical history including all previous operations and medical conditions, including allergies and medications that you take. be honest with your surgeon during your consultation. It is also recommended that you choose a real Board certified surgeon in the specialty that treats the type of sugery you are interested in. Sometime there can be some overlap of specialties, but qualified trainging is the first major question you should ask about. Finally attention to detail before, during and after surgery should help to reduce the occurrence of life threatening complications to only the most rare of times.

Risks associated with gynecomastia surgery include infection, bleeding, asymmetry, under or over correction, skin contour irregularities, loss or change of sensation, recurrence of gynecomastia, pneumothorax and the need for additional surgery.  Potentially life-threatening problems such as deep venous thrombosis/pulmonary embolism are very rare.
 My best advice: make sure that your surgeon  is a board-certified plastic surgeon who can demonstrate lots of experience, SAFELY achieving the types of outcomes you would be pleased with.
 Best wishes.

All surgeries come with risks, mainly bleeding or infection, however the incidence of complications with a board certified plastic surgeon are very low, and the possibility of dying during surgery is probably far less than the probability of dying in a car accident on your way to surgery. Good luck!
