You're constipated. Constipation can occur when not eating enough fiber-rich whole grains, fruits, and veggies, which stimulate digestion. Adults need between 25 and 30 grams of fiber a day, says Dr. Lee. Best foods: High-fiber whole grain breads, nuts, beans, prunes, oatmeal, flaxseed, broccoli, pears, and apples.
A stomach rumble, also known as a bowel sound or peristaltic sound, is a rumbling, growling or gurgling noise produced by movement of the contents of the gastro-intestinal tract as they are propelled through the small intestine by a series of muscle contractions called peristalsis.
Noises within the stomach and bowels are a normal part of gastrointestinal physiology. Most of the time these noises are inaudible to the human ear but when hungry or after eating, bowel sounds may be audible to the person or even others in the near vicinity.
