Abdominoplasty is not suitable in case of obesity (it is performed after losing weight), also, if you smoke (in this case the incisions might not heal poorly, complications are more common), if you are planning a pregnancy (abdominal muscles and skin may stretch again during pregnancy; it is best to perform the operation after all pregnancies). Tummy tuck is usually performed only on healthy people, so it is necessary to warn your doctor about any health problems, medications and dietary supplements.
