Fluid buildup after liposuction, often called seroma, is fairly common and can occur for several reasons: 1. Healing Process: During liposuction, fat and tissue are disrupted, and the body responds by sending fluids to the treated area to promote healing. This can lead to temporary fluid buildup. 2. Lymphatic Drainage: After liposuction, the body's lymphatic system (which helps drain fluids) may be slow to adjust, leading to fluid pooling. Compression garments can help speed up this process by applying gentle pressure and supporting the drainage of excess fluid. 3. Tissue Trauma: The trauma to the tissue during the procedure can cause the blood vessels and lymphatics to leak fluids into the surrounding areas, leading to swelling. 4. Post-Surgical Inflammation: Swelling is a natural part of the recovery process. The body releases fluid to manage inflammation and support tissue repair. It’s important to follow post-operative care instructions, such as wearing compression garments and staying hydrated, to minimize fluid buildup. If the fluid accumulation is excessive or causing concern, you should reach out to your surgeon for guidance.
