Which of the following is a common treatment for functional abdominal pain?

Functional abdominal pain often stems from a variety of non-organic causes, such as stress, anxiety, or dietary sensitivities. Dietary changes are a common and effective treatment approach because they can help alleviate symptoms by identifying and eliminating trigger foods that may exacerbate discomfort. For example, a low-FODMAP diet is frequently recommended for patients with functional gastrointestinal disorders, as certain carbohydrates can lead to increased gas, bloating, and pain.

In contrast, surgery, antibiotics, and radiation therapy are more invasive or pharmaceutical interventions typically reserved for specific conditions such as infections, structural abnormalities, or malignancies. These approaches are not appropriate first-line treatments for functional abdominal pain because the issue is often related to the way the body processes food or responds to stress, rather than an underlying physical abnormality that would require such interventions.
