The ex-president, 92, suffered the brief health scare Thursday while helping to build a house at a Habitat for Humanity construction site.
Carter returned to the site Friday, the Carter Center said.
"He and Mrs. Carter extend their appreciation for the many well-wishes he received worldwide," the center said.
Carter, who served from 1977 to 1981 as the 39th US president, has been in remission from cancer since undergoing surgery in 2015 to remove a small mass on his liver.
