Can you tell me about holloviseral myopathy?

Hollow Visceral Myo-: pathy = inability of intestinal smooth muscle to propel food, air & stool normally, causing obstruction without a lesion that blocks passage. It can be from inherited genetic defects affecting intestinal nerve & muscle cells, genetic syndromes or auto-immune & neurological diseases. Bladder function is often impaired, also. Biopsy of the walls of the bowel & bladder diagnose the type.
