How long does it take a seroma to heal.

The amount of time for a seroma to absorb varies greatly.  A small amount of fluid can be absorbed in a week or two, but if a large seroma exists, it may need to be drained.  I am assuming that the seroma is around your implant.  An ultrasound may be of help in assessing the size and progress of the resolution.  If a seroma persists for too long, however, a chronic fluid accumulation can occur which ususally requires surgery.  Follw the advice of your plastic surgeon.  Best Regards.

Thank you for sharing your question.  If small a seroma can be absorbed by your body of a span of days to weeks but if larger may require treatment through aspiration and compression therapy.  Talk to your surgeon about your concerns, they can provide you the best information based on your specific case.  Best wishes on a speedy recovery.
