A survey of United States gastroenterologists explored their perceptions of dietary therapies for managing irritable bowel syndrome (IBS). The survey, which gathered responses from 1,562 gastroenterologists, found that nearly 60% of providers noted patients commonly associate food with GI symptoms. Most patients with IBS use a trial-and-error approach to diet, with many trying lactose-free and gluten-free diets, though few independently follow a low FODMAP diet. Over half of the gastroenterologists recommend dietary therapy to more than 75% of their IBS patients, with the low FODMAP diet being the most suggested. However, only 21% of providers regularly refer patients to registered dietitians, and only 30% use GI dietitians.

The survey highlighted a general enthusiasm among gastroenterologists for using dietary therapies to manage IBS, particularly the low FODMAP diet, even though patients rarely try it independently. However, referral rates to dietitians, especially those with GI training, remain low. Female providers were found to be more likely to recommend dietary changes as the primary mode of therapy compared to their male counterparts. The results suggest that while dietary approaches are widely accepted, greater collaboration with specialized dietitians may be needed to optimize patient care.
