I have armpit fat and I want to get liposuction done to remove it. Will it come back once I gain weight again?

Liposuction only removes a portion of
fat cells in the target area, and the remaining fat cells always have the
potential to expand and contract with weight gain and loss.Generally, because you have less fat cells,
the potential for weight gain in the target area is less than it was, small
weight gain is always possible in the areas that have been liposuctioned.

Liposuction permanently eliminates a percentage of fat cells in the target area, so you cannot gain weight in these cells. However, the remaining fat cells always have the potential to grow and expand with weight gain. The target area will likely never get the size it was before the liposuction, but there is the potential for growth in the future.

The axillary (armpit) fat can actually be breast glad. I would recommend that you see your doctor and have a thorough consultation and make sure that the underarm swelling is fully diagnosed.
