These conditions don't necessarily preclude you having an abdominoplasty (tummy tuck). The GERD could be problematic in the initial post op period.When we tighten the abdomen the pressure can be increased on both the contents of the abdomen itself (the stomach, intestines, liver, etc) , and also the on the diaphragm that separates the abdomen from the chest contents (the lungs and heart) such pressure can increase reflux for a short period after the surgery, but usually returns to your baseline situation.The pressure on the chest can decrease the expansion of the lung compromising lung function, so if your surgeon gives you a spirometer to use after the surgery, make sure to use it as you are instructed to prevent pneumonia or other problems. If the garment you are in after surgery feels too tight - loosen it
