Lactose intolerance is caused by a lessened ability or a complete inability to digest lactose, a sugar found in dairy products. [1] Humans vary in the amount of lactose they can tolerate before symptoms develop. [1] Symptoms may include abdominal pain, bloating, diarrhea, flatulence, and nausea. [1] These symptoms typically start thirty minutes ...
Lactase persistence or lactose tolerance is the continued activity of the lactase enzyme in adulthood, allowing the digestion of lactose in milk. In most mammals, the activity of the enzyme is dramatically reduced after weaning. [1] In some human populations though, lactase persistence has recently evolved [2] as an adaptation to the ...
Lactose is a disaccharide sugar composed of galactose and glucose that is found in milk. Lactose can not be absorbed by the intestine and needs to be split in the small intestine into galactose and glucose by the enzyme called lactase; unabsorbed lactose can cause abdominal pain, bloating, diarrhea, gas, and nausea.

Gastroenterology, immunology. Food intolerance is a detrimental reaction, often delayed, to a food, beverage, food additive, or compound found in foods that produces symptoms in one or more body organs and systems, but generally refers to reactions other than food allergy. Food hypersensitivity is used to refer broadly to both food intolerances ...
Lactase (EC 3.2.1.108) is an enzyme produced by many organisms and is essential to the complete digestion of whole milk. It breaks down the sugar lactose into its component parts, galactose and glucose. Lactase is found in the brush border of the small intestine of humans and other mammals. People deficient in lactase or lacking functional ...
Lactic acid fermentation is a metabolic process by which glucose or other six-carbon sugars (also, disaccharides of six-carbon sugars, e.g. sucrose or lactose) are converted into cellular energy and the metabolite lactate, which is lactic acid in solution. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells ...
Specifically, it's paying attention to the emotional temper of each conversation, in case someone suddenly starts having a bad time. Turns out most of you just listen to one conversation at a time.
a variety of causes; most commonly due to buildup of gas in the stomach, small intestine, or colon. Abdominal distension occurs when substances, such as air (gas) or fluid, accumulate in the abdomen causing its expansion. [1] It is typically a symptom of an underlying disease or dysfunction in the body, rather than an illness in its own right.
