I had a gastric sleeve on January 8, 2009 in TJ Mexico. The first couple of days were really rough but I followed the doctor's recommendations exactley and soon began feeling much better.
The only complication I had were my lungs! I have asthma and was having problems with chest pain and lung capacity. Wonderful Dr. Betancourt and Dr. Almanza were both at my bedside within minutes of experiencing the chest pain and got me up out of bed walking around, using the incentive spirometer and soon, I was breathing and feeling better.'' I never had any nausea but did experience a lot of gas. Walking, lots of Water (when you are cleared to drink it) and Mylanta worked wonders.
Just remember that surgery is surgery! There is no such thing as risk free anything. Anyone who tells you that there are no complications or risks aren't telling you the truth. Even the best hospitals and doctors can't guarantee you a risk free, complication free surgery! MRSA, and other infections are very common no matter where you get your surgery (I am a nurse and work in geratric long term, skilled care and rehab and see it all the time!). The main thing to know is whether or not your doctor gives you IV and oral antibiotic (I got both after surgery and am still taking the oral antibiotics). Don't pass on the oral antibiotics because you think you feel great. Take them anyway and be ever watchful for any kind of infection. The sooner you get it treated... the less likely you are to have a life threatening complication.
