To provide you with the most relevant and helpful information, and understand which Conversely, functional disorders may respond to dietary measures, enzyme preparations which facilitate digestion, adsorbents and agents that decrease surface tension, treatments that alter gut flora, or drugs that modify gut transit. Chronic belchers may better understand the role of aerophagia by observing their swallowing mechanics in a mirror. Other centers rely on 14C or 13C-labelled substrates, with measurement of breath 14CO2 or 13CO2, although special facilities are necessary for these analyses.

If obstructions occur in the small intestine, gas pockets can accumulate containing as much as 3,500 cubic cm (200 cubic inches) of gas. Other methods of quantifying gastric emptying include isotopic breath tests (eg, 13C-octanoate) and ingested capsule techniques. However, normal values for these tests are less well defined.34 Hydrogen measurement may be extended to 10 hours to test for maldigestion of complex carbohydrates. The intestines break down the food even further in a process that sometimes releases gases. However, their utility in patients with excess gas and bloating is unexplored.45 Hydrogen production and gaseous symptoms decrease when children with sucrase-isomaltase deficiency are given sacrosidase from Saccharomyces cerevisiae.46, Agents which reduce surface tension of gas bubbles and adsorbents are commonly employed for gaseous symptoms (Table 5).
