Q. A 28-year-old woman presents to the primary care clinic for recurrent lower abdominal pain and altered bowel habits for the past six months. She complains of abdominal bloating along with cramping pain. Her symptoms are often relieved after bowel movements and are not associated with nocturnal symptoms or weight loss. She has no significant past medical history and her family history is unremarkable. Her vitals are normal and the physical examination is unremarkable. Routine blood tests, including complete blood count, thyroid function tests, and celiac serology, are normal. What is the best next step in management?
