Stomach Thumping Sensations: Common Causes & When to Worry

Thumping, gurgling, or rumbling in the abdomen (borborygmi) is usually normal digestion. Common causes:

• Hunger: Empty stomach contracts (migrating motor complex).
• Gas: Movement of gas bubbles through intestines.
• Digestion: Peristalsis moving food/fluid, especially after large meals.
• IBS/IBD: Altered motility, hypersensitivity → exaggerated sensations with pain, diarrhea/constipation.

See a doctor if: Persistent, severe pain; blood in stool; weight loss; fever; or symptoms disrupt daily life. Evaluation may include labs, imaging, endoscopy.
