Thank you for sharing your question. In most instances you need not remove your nails as the instruments used during surgery to monitor your oxygen readings can be applied to another part of your body. It is always best to ask questions of your surgeon or anesthesiologist as they know the full details of the procedure and your health history. Hope this helps.
Mommy makeovers, like all general surgical procedures, require modern pulse oximeters to measure one's oxygen level in the blood as well as an ongoing picture of your heartbeats. Short acrylic nails do not create a problem unless the color of your nails is very dark, such as dark blue or black. This sometimes creates a problem that can be obviated by either putting the oximeter on your little finger or your toes. Therefore, the short answer is NO, short acrylic nails do not have to be removed with a Mommy Makeover if done in a certified surgery center or hospital and they will not interfere with your surgery.
