causes for intestinal blockage
This process can be interrupted or halted by the presence of a bowel obstruction, which is a blockage that prevents the passage of intestinal contents. The cause of the blockage can be mechanical, meaning that there is a physical obstruction. Mechanical blockage may be caused by scar tissue, adhesions, entrapment through a hernia, foreign bodies, gallstones, tumors, impacted feces, and volvulus (twisting of the intestines).
