However, hydrogen production begins when certain carbohydrates are fermented by anaerobic intestinal bacteria.<\/p>\n<p data-start=\"1006\" data-end=\"1415\">The majority of anaerobic bacteria are located in the colon. In contrast, the small intestine normally contains only a minimal number of anaerobic bacteria, mainly in its distal segment. In pathological conditions such as small intestinal bacterial overgrowth, the number of anaerobic bacteria in the small intestine increases significantly. As a result, gas production, including hydrogen, becomes excessive.<\/p>\n<p data-start=\"1417\" data-end=\"1701\">In addition to the liver and kidneys, the lungs are also considered organs of excretion. Certain gases produced during bacterial metabolism in the intestine are released through the lungs. One of these gases is hydrogen, which can be measured using specialized breath testing devices.<\/p>\n<p><img data-dominant-color=\"f5dfe9\" data-has-transparency=\"false\" style=\"--dominant-color: #f5dfe9;\" loading=\"lazy\" decoding=\"async\" class=\"wp-image-1575 alignnone not-transparent\" src=\"https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-17676447-400x400.webp\" alt=\"\" width=\"301\" height=\"301\" srcset=\"https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-17676447-400x400.webp 400w, https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-17676447-800x800.webp 800w, https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-17676447-280x280.webp 280w, https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-17676447-768x768.webp 768w, https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-17676447.webp 1500w\" sizes=\"auto, (max-width: 301px) 100vw, 301px\" \/><img data-dominant-color=\"e4c6d3\" data-has-transparency=\"false\" style=\"--dominant-color: #e4c6d3;\" loading=\"lazy\" decoding=\"async\" class=\"wp-image-1574 alignnone not-transparent\" src=\"https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-12221146-400x400.webp\" alt=\"SIBO\" width=\"300\" height=\"300\" srcset=\"https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-12221146-400x400.webp 400w, https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-12221146-800x800.webp 800w, https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-12221146-280x280.webp 280w, https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-12221146-768x768.webp 768w, https:\/\/gastroclinic.am\/wp-content\/uploads\/2024\/03\/67743-12221146-jpg.webp 1500w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<h2 data-start=\"1708\" data-end=\"1729\">Examination Method<\/h2>\n<p data-start=\"1731\" data-end=\"1913\">Hydrogen produced in the intestinal lumen is absorbed into the bloodstream and subsequently excreted via the lungs. For this reason, its concentration can be measured in exhaled air.<\/p>\n<p data-start=\"1915\" data-end=\"2192\">Measuring breath hydrogen levels allows assessment of anaerobic bacterial activity in the intestine and helps identify deviations from normal values.

It is a modern diagnostic tool for evaluating disorders of the intestinal microbiota and intolerance to specific dietary carbohydrates, such as lactose and fructose.<\/p>\n<p data-start=\"2496\" data-end=\"2722\">The test is performed using a portable hydrogen analyzer.
