Eating patterns of patients with intestinal bacterial overgrowth syndrome

The objective. Intestinal bacterial overgrowth syndrome is widespread among gastroenterological patients. Treatment of intestinal bacterial overgrowth with antibiotics yields an insufficient effect, recurrence rates amount to 40%. One of the most powerful factors of changing intestinal flora is related to nutrition specificities.

Patients and methods. In 685 patients who performed a hydrogen-methane breath test with lactulose data about actual nutrition were collected using the 24-hour dietary recall method. Meals of the dietary intakes were decomposed into ingredients according to recipes and compared with intake norms of the healthy eating pyramid for a given calorie value of the diet. According to the test findings, patients were distributed into subgroups, each corresponding to a variant of intestinal bacterial overgrowth (higher concentrations of Н2, СН4, and Н2 + СН4 in breath), and a subgroup without signs of intestinal bacterial overgrowth.

Results. As has been found, individuals with intestinal methanogenic flora overgrowth have a characteristic higher consumption of fruits and protein meals, for individuals with intestinal hydrogen-producing flora overgrowth have a characteristic higher intake of fats; as regards protein meals, individuals with intestinal bacterial overgrowth syndrome were notable for a significantly less intake of meat, patients with intestinal methanogenic flora overgrowth consuming more fish products, whereas individuals with hydrogen-producing flora overgrowth have a characteristic tendency to take more poultry meat.

Conclusion. Nutrition specificities that we have found permit to work out measures for dietetic correction of patients’ diets as addition to antibacterial therapy to prevent recurrences of intestinal bacterial overgrowth syndrome.

Key words: hydrogen, lactulose breath test, methane, actual nutrition.
