Functional gastrointestinal (GI) disorders, also called disorders of gut-brain interaction (DGBI), are a common group of conditions that can cause various symptoms, including abdominal pain, bloating, constipation, and diarrhea. These symptoms can significantly impact a patient’s quality of life, and effective diagnosis and treatment require a multidisciplinary approach.
The first step in diagnosing a functional GI disorder is to obtain a thorough medical history and conduct a physical exam. Diagnostic tests, including hydrogen and methane breath tests, blood tests, stool tests, or imaging studies, may be ordered depending on the patient’s symptoms.
Once confirming a diagnosis, a multidisciplinary team can work together to develop an individualized treatment plan. This team may include a gastroenterologist, a dietitian, and a mental health professional.
