Although most abdominal bowel sounds may be a due to digestion, medical conditions that can cause this are Crohn's disease, ulcerative colitis and infectious enteritis, notes the National Institutes of Health's MedlinePlus. Some other possible causes of strange stomach noises are an intestinal obstruction and bleeding in the gastrointestinal tract, according to Healthline.
When stomach noises are overly loud, they are referred to as "hyperactive." In most cases, loud abdominal noises may be normal, but frequent occurrences of this symptom can indicate a possible medical issue, such as the ones cited. Many times, other symptoms also accompany bowel noises, including gas, weight loss and blood in the stool. Patients should see a doctor if they experience any of these troubling symptoms or persistent diarrhea.
Because there are different conditions associated with hyperactive bowel sounds, different tests may be useful for a proper diagnosis, including blood tests, endoscopy and CT scans. Once the direct cause is diagnosed, a treatment can be recommended. For example, ulcerative colitis, which involves inflammation of the colon's lining and subsequent formation of ulcers, may require different medications, including corticosteroids and antibiotics, according to the Crohn's & Colitis Foundation of America. Crohn's disease is another type of inflammatory bowel condition.
When the medical condition causing hyperactive bowel sounds is either an intestinal obstruction or gastrointestinal bleeding, it can require prompt medical attention, as noted by the National Institutes of Health's MedlinePlus.
