In a nutshell
Gurgling and rumbling occur when gas and fluid move through the digestive tract. These sounds also occur without hunger and, on their own, say little about intestinal health.
Why does it happen?
Intestinal muscles move and mix the contents. Gas bubbles and fluid are pushed through sections that vary in width. The resulting vibrations can be heard through the abdominal wall; their volume and frequency vary.
Frequency
Bowel sounds are part of normal digestion and occur in healthy people. Whether they are audible varies with intestinal movement, fluid, and gas.
Frequency is a qualitative description, not your individual probability.
Is it normal?
Varying loudness is normal.
When to seek advice
Severe abdominal pain, abdominal swelling, persistent vomiting, or inability to pass stool or gas need prompt medical assessment.
