Is acid reflux common after having general anesthesia for Vaser Lipo? I'm 48 hours post op.

This can happen after treatment. If it persists, I recommend following up with your Doctor. You have swelling, which can last 3-6 months after your procedure. I recommend adding hyperbaric oxygen and lymphatic massage along with your compression to help decrease swelling. To improve your final results, I also recommend adding vanquish for further fat removal, exilis/venus legacy for skin tightening, cellutone/z wave to make the skin smooth, remove scar tissue, and improve the skin’s appearance. See an expert. Best, Dr. Emer

Liposuction is a great way to de bulk fat, and contour your body, but there is a unglamorous healing phase.Reflux can happen immediately post procedure if your body doesn’t like the meds used for pain control, also a tight compression garment in the abdomen region can press up on the stomach and cause reflux.Try other garments, or perhaps adjust it less tight. It will get better.Best.

Hi and welcome to our forum!
Acid reflux is usually the result of incompetence of the esophago-gastric junction. As a result, gastric acid reluxes upward into the esophagus, causing irritation of the esophageal lining, resulting in pain. Vaser liposuction will not cause reflux, but the positioning during surgery, application of external abdominal pressure with a compression garment after surgery, and prolonged periods of inactivity while lying flat, may exacerbate symptoms. 
I recommend the use of antacids, H2 inhibitors, elevation of the head of the bed, and most importantly, being up and about. You should contact your physician if symptoms persist or are severe.
Best wishes...
