Intestinal sounds, also known as bowel sounds, are noises produced by the movement of gas and fluid in the digestive system. These sounds occur as the intestines contract and relax to help digest food and move it through the gastrointestinal tract. They can vary in frequency and intensity, often described as gurgling or rumbling. These sounds are a normal part of digestion and can be influenced by factors such as hunger, digestion, and the presence of certain foods. While occasional loud or unusual sounds are typically harmless, persistent changes may warrant a consultation with a healthcare professional to rule out any underlying issues.
