Reduction of cardiovascular complications during delivery hospitalization in patients undergoing bariatric procedures
Authors' conclusion
In summary, our research indicates that bariatric surgery is associated with a decreased risk of cardiovascular complications during delivery. This study highlights how insights from bariatric surgery outcomes could shape clinical guidelines for managing obesity in pregnant women.
