A grumbling stomach after meals may be caused by irritable bowel syndrome, indigestion, acute gastroenteritis and other reasons. 1. Irritable Bowel Syndrome (IBS): Higher stress, frequent depression, and excessive mood swings can easily trigger IBS, resulting in a grumbling stomach after meals, accompanied by diarrhea, abdominal pain, and other symptoms. 2. Indigestion: Eating too much greasy food and high protein food increases the burden on the stomach and intestines, inducing indigestion and causing the stomach to gurgle after meals, accompanied by bloating, nausea and other symptoms. 3. Acute gastroenteritis: Eating unhygienic food triggers acute gastrointestinal inflammation, resulting in a gurgling stomach, accompanied by bloating, diarrhea, abdominal pain, nausea, vomiting and other symptoms. There are many other reasons why your stomach always rumbles after meals, so we recommend that you seek medical attention to identify the cause and follow the doctor’s instructions to avoid delaying your condition.
