My husband has developed a condition where, when he is lying on his back and begins to sit up, a large soft bulge appears in the midline of his abdomen. It can be pushed back in. The muscle seems to have split midline. I assume this is some kind of hernia. Doctors do not seem concerned, since it is large - maybe 8" long - and therefore unlikely to become strangulated. What is this kind of hernia called? He was just diagnosed with a sliding hiatal hernia, which will be followed up on. I am wondering if there is a connection between these two hernias.
Thanks. Jane
