Stomach bloating after tummy tuck and liposuction.

Thanks for your inquiry but without an exam it is hard to advise.  Frankly your own plastic surgeon should be the first to comment and please visit him/her.  Weight gain, medical conditions, irritable bowel, or issues with your tummy tuck are all in the differential diagnosis.  If needed your surgeon will recommend you see your medical doctor.  

At three months post op much of the swelling is typically resolved. I recommend visiting with your surgeon to discuss your concerns and determine what may be causing your symptoms.

Most of the time there is an expected amount of swelling associated with an abdominoplasty that can last quite a while.  Usually, activity is related to increased swelling and after 3 months a patient is typically back to normal activity.  This doesn't mean that the swelling and firmness has ended.  In most cases this is normal and will subside in time but you should talk with your surgeon and get examined to make sure this is the case.  Hope this helps!
