Does Sleeping on my Side Affect Liposuction Healing?

Sleeping on one side can tend to cause that side to swell more than the upturned side. However, at 4 weeks following surgery, it is not likely to have much of an effect. However, it is best to discuss this with your surgeon.

While swelling may be more apparent on the side you sleep on, it shouldn't be that visible since it's been a month after your surgery.

I doubt that at one month you would have any deleterious effect from sleeping on your side. The collagen retraction of the septae around your fat lobules is continuing to tighten and you should get an improvement in the next six months.

Your sleeping position should not impact the healing of your liposuction procedure.  Relax and rest peacefully.

At 4 weeks after liposuction, there is enough scar tissue and healing to prevent any damage to your final result.  The swelling on the side which you lie one may take longer to resolve, but that is the worse case scenario.
