    There is limited research on dietary interventions for Small intestinal bacterial overgrowth (SIBO), and most recommendations are based on weak or anecdotal evidence. Although certain dietary patterns like low-FODMAP, low-sugar, or specific carbohydrate diets may alleviate some symptoms, their effect on SIBO itself remains unclear.

    Very little research has been done on dietary interventions for SIBO specifically, so most recommendations are based on weak or anecdotal evidence. Some dietary patterns, such as the low-fodmap, low-sugar or specific carbohydrate, or elemental diets may reduce some of the symptoms associated with SIBO, but their effects on the condition itself are unknown.[1][2] [3][4]
