How can I prevent a fat embolism during and after gynecomastia surgery?

Thank you for sharing your excellent question.  With an experienced surgeon the risks of either complication are very small.  Skin necrosis is only seen in cases of liposuction that involves heating of the tissues, such as VASER, while fat embolism can not be "prevented" but its development is fortunately rare.  

Fat embolism- extremely rare and unheard of so don't have to worry at all about it.Hypothyroidism- if your TSH is normal, you are as good as normal.Skin necrosis- only liposuction never causes skin necrosis.Information on gynaecomastia surgery in ddelhi
Hope I was able to answer to your queries.

Treated hypothyroidism is unlikely to have any serious consequences for liposuction surgery.Skin necrosis is most unlikely in a healthy inn smoking individual having liposuction for gynecomastia using conventional liposuction (i.e. not laser or ultrasonic). The main cause of significant skin necrosis for this type of surgery would be severe infection.Fat embolism occurs with with liposuction but is not normally clinically significant. It is when large volumes of fat are re-injected, such as with a Brazilian Butt Lift, that most serious fat embolism occurs. Fat embolism is most unlikely to be clinically significant in normal healthy individuals having liposuction to the breasts (gynecomastia).Best wishes.
