A seroma is a collection of serous fluid, the clear, watery fluid naturally produced by the body, that accumulates in a space created during surgery. Seroma is one of the most common complications following a tummy tuck (abdominoplasty), occurring in roughly 15 to 30% of patients depending on the extent of the procedure.
Why Seroma Develops After a Tummy Tuck
During a tummy tuck, the skin is lifted and separated from the underlying abdominal fascia over a large area. This disrupts lymphatic channels and creates a potential space where fluid can pool. The body's natural response to surgical trauma also contributes to fluid production. Factors that increase seroma risk include:
- Extensive skin dissection (more common in full tummy tucks than mini tummy tucks)
- Simultaneous liposuction of the abdomen
- Poor compression garment compliance
- Returning to physical activity too soon
- Certain medical conditions that impair lymphatic function
Recognizing Seroma Symptoms
A seroma most commonly appears within 1 to 3 weeks after surgery. Patients may notice a soft, squishy bulge under the skin of the lower abdomen that may feel like it sloshes when moved. Other symptoms include a sense of fullness or pressure, localized swelling that seems asymmetrical, and occasionally mild discomfort or warmth over the area. Unlike infection, seroma does not typically cause fever or severe pain.
How Seroma Is Treated
Treatment depends on the size and persistence of the seroma. Options include:
- Watchful waiting for very small seromas that may reabsorb on their own
- Needle aspiration, draining fluid with a syringe in your surgeon's office
- Surgical drain placement for large or recurring seromas
- Sclerotherapy, injecting a solution to close off the fluid space in persistent cases
Tips for Prevention
While seromas cannot always be prevented, the following measures significantly reduce risk: wearing your compression garment continuously for the prescribed period, limiting physical activity and avoiding lifting during early recovery, keeping all follow-up appointments so your surgeon can catch fluid early, and undergoing lymphatic massage once your surgeon clears you. Some surgeons also use quilting sutures or progressive tension sutures to reduce dead space and lower seroma rates.
