Lactose intolerance is a digestive trouble that results in stomach upset of lactose upon its economic consumption . It is a very plebeian problem affecting about 75 % of the world population and about 25 % of the Americans .
What Is Lactose?
Lactose is a disaccharide that is break down by body into glucose and galactose by an enzyme scream lactase . Mammalian milk is fat in lactose that is responsible for nourishment of most of the animals , including human babies . Lactase , an enzyme , is found at the small intestine brush border where it is responsible for the digestion of lactose . The action of lactase is at its peak at the time of birth for digestion of lactose because tit milk is the only source of nutrition . With grow eld , the activity of Lactaid enzyme is also reduced as the child see to nutrify from other sources . The individuals who still have continuity of lactase enzyme fall in the group of lactase persistence , whereas , those who parade decreased activeness of lactase fall in lactase non - persistence chemical group .
Can You Become Lactose Intolerant All Of A Sudden?
Thus , the reduced activity of lactase leads to maldigestion / indigestionof lactose . The reduction in the activity of Lactaid happens over an extended period of time , ordinarily after 2 to 12 years of years , so in most cases lactose intolerance is a slow process ; however , it can bump suddenly , which is rare and uncommon , but not inconceivable . In most guinea pig , lactose intolerance is not sudden because the down regulation of lactase does not happen suddenly and bump in meter . Lactose intolerance is rough-cut in Asian , African , Southern Europe and Middle East area . It is less normally construe in masses who exercise domestication of cattle and are dependent on unfermented Milk River and dairy products as an of import source of food . People from northerly Europe maintain this mental ability to digest milk and dairy products and lactose intolerance is rarely seen in descendent of this region .
How Does Lactose Intolerance Occur?
Lactose intolerance pass in 75 % people all around the world by genetically programmed reduction in Lactaid synthesis that is an enzyme responsible for lactose breakdown as a part of festering . It is generally seen around the age of 20 - 40 years of life . This is know as primary lactase deficiency . In addition , some citizenry abide from gastrointestinal disorders such as inflammatory intestine disease , GI infection ( infective enteritis ) , abdominal surgeries , celiac disease , Crohn ’s disease and other wellness disorder that do thin out lactase body process , which is known as secondary lactase insufficiency . Primary as well as secondary lactase deficiency should be chuck out from innate Lactaid want , which is a rare autosomal recessive upset that affects exclusively babe and may raise fatal to them if not detected early in life . In all these cases of lactose intolerance , the lack of lactase enzyme leads to malabsorption / inabsorption of lactose present in intestines , which increase the water content in intestines and the fermentation of colonic microflora leads to production of gases ( such as hydrogen , carbon dioxide and methane ) along with short range of mountains roly-poly Zen that causes lactose intolerance . This causes symptoms ofabdominal pain in the ass , bloating , looseness of the bowels , abdominal cramping , andflatulence .
How is Lactose Intolerance Diagnosed?
Lactose intolerance is diagnose by endoscopic duodenal biopsy that is the aureate criterion for detecting lactase deficiency . Other tests admit genetic tests and lactose hydrogen breath tests and lactose margin examination .
What is The Treatment of Lactose Intolerance?
Lactose intolerance has no lasting treatment , but can be pull off with the object at improving GI symptoms along with reduce malabsorption . The melioration of GI symptom is achieved by modifying dieting and restrain lactose and FODMAP ( fermentable oligosaccharide disaccharide simple sugar and polyols ) in single diet along with maintenance of adequate atomic number 20 intake that is important in preventing lowly pearl disease in patients with restricted Milk River and dairy diet . This can be achieved with calcium replacement through other foods rich in calcium or Ca accessory . Another direction approach to lactose intolerance is replacement with lactase enzyme .
