The dangers of tummy tuck surgery include skin abnormalities, edema, thinning of the abdominal wall, and destruction of nerve tissue. 1. Skin abnormality: if the suction is not uniform when performing tummy tuck, it will lead to unevenness in the abdomen. If the fat is suctioned thinly and the skin is damaged, it will lead to depressed scarring and hyperpigmentation in the skin. 2. Edema: after tummy tuck surgery, due to tissue damage and some swelling fluid remaining under the skin, edema may appear in the suctioned area, which usually subsides slowly. 3. Thinning of the abdominal wall: Tummy tuck surgery will lead to thinning of the abdominal wall, which will cause the abdominal skin to become loose, and the elasticity of the subcutaneous tissues will be weakened and the ductility will be limited. 4. Destruction of nerve tissue: excessive postoperative negative pressure may destroy the nerve tissue, resulting in a reduction in the feel of the suctioned tissue and skin sensation. If you need tummy tuck surgery, it is recommended to go to the hospital in time, follow the doctor’s instructions and standardize the treatment under the doctor’s guidance.
