I had gastric sleeve surgery 5 months ago, I lost 75lbs. I'm considering a male tummy tuck with six pack?

Congratulations on your weight loss!  I don't know the surgeon you mention, but I do have some general advice when it comes to seeking out a surgeon, whether it is a surgeon in the US or outside of the country.  First, make sure the surgeon(s) you are researching have met the highest qualifications in their country (in the US this means the surgeon is certified by the American Board of Plastic Surgery, and is a member of the American Society of Plastic Surgeons). This does not mean you are guaranteed to get the results you want, but at least you have chosen a surgeon whose knowledge, safety, and ethics have been evaluated.. Next, make sure the surgeon has been trained to do the type of surgery you are interested in (not a weekend course!, but an actual legitimate, recognized residency program). Also check if the surgeon has experience doing that type of surgery (you can start by looking at the surgeon's before and afters, though it is not unheard of for surgeons to falsely show other surgeons' results), hold hospital privileges at a nearby hospital (in case of emergency), and give you the sense of trust you need from your surgeon. Tummy tuck surgery in particular carries certain risks, and one of them is a deep venous thrombosis (DVT) in the leg, and this is potentially fatal. In the US, in accredited operating rooms there are certain safety measures taken, and certain protocols are followed after surgery. A reputable surgeon in another country would likely have similar concerns, but the rules in each country vary. Also, flying increases the risk of DVT so be careful how you time your surgery and travel plans. Please do not choose a surgeon outside of the country that you know nothing about, or only know one friend who had a nice result. That friend could have gotten lucky. You want to plan for good results, not hope for luck. There are obviously excellent surgeons all over the world, but figuring out who they are is not easy, and when you have so many great ones to choose from in New York, or elsewhere in the US, you need to have a really good reason to go elsewhere.A side note- For the best result, timing matters. I would recommend waiting until you are no longer actively losing weight, and have maintained a stable weight for at least 6 months.

Thank you for your question.  I recommend seeing a board certified plastic surgeon for a tummy tuck.  I would recommend not going to Columbia for surgery.  Should you have any concerns or complications your surgeon will be available to see you, if needed.  Be sure to review their before and after pictures and read online reviews.  Best of luck to you and congrats on your weight loss!
