Causes

Most of the sounds you hear in your stomach and intestines are due to normal digestion and are no need for concern. Many conditions can cause hyperactive or hypoactive bowel sounds. Most are harmless and do not need to be treated.

The following is a list of more serious conditions that can cause abnormal bowel sounds.

Hyperactive, hypoactive, or missing bowel sounds:

• Blocked blood vessels prevent the intestines from getting proper blood flow. For example, blood clots can cause mesenteric artery occlusion.
• Mechanical bowel obstruction is caused by hernia, tumor, adhesions, or similar conditions that can block the intestines.
• Paralytic ileus is a problem with the nerves to the intestines. Reduced nerve activity can result from:
  • Blood vessel blockage
  • Bowel blockage
  • Chemical imbalances such as hypokalemia
  • Infection
  • Overexpansion of the bowel
  • Trauma

Other causes of hyperactive bowel sounds:

• Crohn's disease
• Diarrhea
• Food allergy
• GI bleeding
• Infectious enteritis
• Ulcerative colitis
