After heart or lung transplantation, the stomach tends to empty much slower than normal. This slow emptying is called "gastroparesis." Gastroparesis is uncomfortable and often leads to nausea and vomiting. In addition to drastically impacting quality of life, severe nausea and vomiting can also lead to malnutrition and an inability to take oral medications, contributing to complications of transplantation. Treatments for gastroparesis include both medical and surgical therapies that work for some but not all patients.
