10) Abdominal sounds
Abdominal sounds are a natural part of the digestive process. The movement of the intestines produces them as they drive food. Since those organs are hollow, the noise they produce is usually similar to an echo through the abdomen. We can compare them to the sounds produced by water pipes. The fact that they produce sounds is proof that the digestive tract is working. In fact, as part of a medical examination, auscultation can be performed to register whether or not there are normal abdominal sounds. This is nothing but an evaluation of abdominal sounds by listening to the abdomen with a stethoscope.
Needless to say, these sounds are generally harmless. But in lactose intolerance, the accelerated movement of the intestines by the intestines causes normal sounds to intensify both in frequency and intensity. Increased abdominal sounds are often associated with diarrhea because they signal speedy bowel movements, and it is important to differentiate the symptom with other diseases featuring increased intestinal sounds, as in intestinal obstruction.
