Liposuction can help the upper stomach if the fullness is mainly pinchable fat under the skin and your skin has enough elasticity to shrink smoothly afterward. The specific tool, such as traditional liposuction, power-assisted liposuction, or ultrasound-assisted liposuction, is usually less important than choosing the right candidate and treating the area evenly. An in-person exam is important because upper abdominal fullness can come from different things. If the fat is mostly inside the abdomen around the organs, liposuction will not remove it. If there is loose skin, stretch-damaged skin, or muscle separation, liposuction alone may not give the flatter result you want and can sometimes make looseness or waviness more noticeable. In that situation, a tummy tuck is the procedure that addresses skin and muscle, even if you ultimately decide you do not want one. If you are a good liposuction candidate, your surgeon may recommend treating the full abdomen and often the flanks rather than only the upper stomach, so the contour blends naturally with the waist. A consultation with a board-certified plastic surgeon will help determine whether liposuction alone is reasonable for your anatomy.
