This is a minimally invasive medical procedure with real complications, and your director reads them to you before consent is signed. Bruising, swelling, tenderness and patchy numbness across the treated skin are expected in the early days. Less frequently, patients develop contour irregularity, a seroma, firm nodules in the fat layer, worsened skin laxity, infection at the micro-entry point, or visible asymmetry between the two sides of the waist. Prolonged altered sensation is uncommon and does occur.
A belly carries its own particular hazards. It is a broad surface, so unevenness is easier to see there than on a limb; both flanks have to be judged against each other with you standing upright; and a garment worn loosely allows fluid to pool exactly where you would least like it. Disclose everything at consultation, including previous abdominal operations, blood-thinning medication, supplements and any past reaction to anaesthetic.
Afterwards, wear the compression as instructed, keep the entry point clean and dry, and telephone the clinic promptly if pain, redness, discharge or swelling starts increasing after the first few days. A resident medical director is on site throughout opening hours, so there is always a doctor available to inspect the area.
