This book presents and discusses research which examines how obstetric morbidities are associated with obesity, as well as the importance of this area of research because it has reached epidemic proportions. Also discussed herein is how scanning obese patients is one of the major challenges of sonographers and it limits their ability to fully evaluate an individual's condition in general and anatomy survey in particular. Indeed, obesity represents a critical modifiable risk factor for adverse pregnancy outcomes with serious obstetric implications for both the mother and the foetus.
