If someone has blocked bowels, can stomach still growl?

Usually loudly. Mechanical bowel obstructions are often characterized by quite loud bowel sounds as the intestine upstream from the blockage try to overcome the obstruction by contracting stronger than normal. These contractions are responsible for the cramping pain associated with bowel obstructions. A telltale sign of a worsening obstruction is when the bowel sounds diminish, as the bowel function subsides.
