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.
Reduced (hypoactive) bowel sounds include a reduction in the loudness, tone, or regularity of the sounds. They are a sign that intestinal activity has slowed. Hypoactive bowel sounds are normal during sleep. They also occur normally for a short time after the use of certain medicines and after abdominal surgery.
