methane and Alactasia

methane has been researched along with Alactasia in 26 studies

Methane: The simplest saturated hydrocarbon. It is a colorless, flammable gas, slightly soluble in water. It is one of the chief constituents of natural gas and is formed in the decomposition of organic matter. (Grant & Hackh's Chemical Dictionary, 5th ed)
methane : A one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms. It is a colourless, odourless, non-toxic but flammable gas (b.p. -161degreeC).

( Camillo, MD; Caprilli, R; Marinaro, V; Vernia, P, 2003)
"The breath methane test for lactose malabsorption has a lower sensitivity and specificity than the breath hydrogen test and therefore does not replace the lactose breath hydrogen test."3.70Ineffectiveness of breath methane excretion as a diagnostic test for lactose malabsorption. ( Bolin, TD; Kyaw-Hla, S; Thein-Myint, T, 1999)
"Lactose malabsorption, by the breath hydrogen test, and lactose intolerance (presence of symptoms) were studied in twenty healthy Italian subjects after intake of 12."3.66Respiratory excretion of hydrogen and methane in Italian subjects after ingestion of lactose and milk. ( Andreoletti, M; Bianchi, P; Bozzani, A; Marcucci, F; Mussini, E; Velio, P; Zuccato, E, 1983)

"While lactose malabsorption is a well-investigated condition, few epidemiologic data are available for fructose and sorbitol malabsorption."1.42Carbohydrate Malabsorption and Putative Carbohydrate-Specific Small Intestinal Bacterial Overgrowth: Prevalence and Diagnostic Overlap Observed in an Austrian Outpatient Center. ( Enko, D; Halwachs-Baumann, G; Kimbacher, C; Kriegshäuser, G; Mangge, H; Stolba, R, 2015)
