The small study in the journal Obstetrics and Gynecology says some women who deliver by cesarean section may be able to check out of the hospital the next day.
The research followed more than 350 Malaysian women who either went home one or two days after having a C-section.
The women who were discharged sooner seemed to have no more problems than those who stayed longer.
But researchers stress these results don't mean hospitals should start kicking women out the day after a C-section. But they do suggest that a next-day discharge is something women can talk about with their doctors.
Right now, in the United States, women typically stay in the hospital for three to four days after the procedure.
