Can you die from gynecomastia surgery? Has anyone died from it?

Technically you can die from any surgery. You can also die from driving your car or having a weird reaction to a food. You should meet in person and speak with an American board of plastic surgery certified surgeon to discuss the risks and benefits of the procedure your interested in. If your seriously considering gynecomastia surgery it will be worth your time.Best

Thank you for sharing your questions with the forum. 
There is a risk of death in every procedure performed, made greater or lesser depending on any number of patient and procedural factors. Rates of death for plastic surgery is approximately 1 in 50,000 cases. 
Your Plastic Surgeon will discuss with you the benefits, risks, and alternatives of any procedure you are considering as part of the informed consent process. 
Good luck to you with your decision and treatment.

Any surgery has risks associated with it. General anesthesia increases these risks. Elective aesthetic procedures are appropriate to do when the Pro's outweigh the Con's. I suggest you meet with a Board Certified Plastic Surgeon who operates an an accredited facility with Board Certified Anesthesiologists. A consultation with a surgeon is the best place to ask these questions. I wish you well.
