Hello, and thank you for your question about how to get rid of fluid accumulation in your lower abdomen following a tummy tuck. At just 4 weeks post-op, what you’re describing could very well be a seroma, which is a pocket of clear fluid that collects under the skin after surgery — particularly common after procedures like tummy tucks where large areas of tissue are lifted. If you feel a soft, squishy, or sometimes firm area that moves when pressed, or you notice a bulge that hasn’t gone away, it’s important to have your surgeon evaluate it. Some seromas resolve on their own if they are small, but others need to be drained with a syringe and needle in a sterile environment — a procedure called aspiration. This is a quick, in-office procedure and often provides immediate relief. Do not attempt to drain it yourself, as this can cause infection or injury. The fluid is sterile until it’s exposed to bacteria, and introducing anything unclean could lead to a serious complication. If left untreated, a seroma may: Harden and form a pseudocapsule (scar tissue pocket) Cause prolonged swelling or discomfort Become infected, turning into an abscess Your surgeon might also recommend continued compression garment use, lymphatic massage, or drain placement if fluid continues to accumulate. Sometimes, if a seroma becomes chronic or fibrous, surgical revision may be necessary — but that’s usually a last resort. You’re doing the right thing by paying attention to your body. Please contact your plastic surgeon right away so they can assess whether you need drainage and ensure your recovery continues smoothly. Wishing you a safe and comfortable resolution ahead.
