Umbilical Hernia and Pregnancy
In adults, too much abdominal pressure can cause an umbilical hernia. Possible causes in adults include:
Fluid in the abdominal cavity (ascites)
Previous abdominal surgery
The surgery is necessary only when your doctor feels there is risk of herniation of the bowel through it, or if the pain from it is so great as to interfere with your normal daily activity. Otherwise, it can be ignored and addressed—if need be—after the baby’s born. If you end up having a C-section, it can fixed at that time!
You can cheat an umbilical hernia by wearing an abdominal binder, which will do no harm, and maybe even delay any surgery until after delivery.
