-it is caused by a deficiency in the enzyme lactase which is produced in the small intestine-the small intestine may stop producing lactase after a short term illness or surgery to the small intestine

-refers to the body’s inability to easily digest lactose, a natural sugar found in milk and dairy products


-upon consumption of dairy products, one may experience nausea, abdominal cramping, diarrhea, gas, and swelling in the stomach-symptoms usually occur between 30 minutes to 2 hours after consumption of dairy products

-abstinence from milk and dairy products-addition of lactase to milk-consumption of lactase in the form of a tablet-in order to avoid calcium deficiency,one should consume calcium supplements, eat foods rich in calcium, and drink orange juice containing added calcium

-highly prevalent in adults; approximately 30 million Americans have some form of alactasia when they reach 20 years of age- typically affects Native Americans and people of Asian, South American, and African descent-some newborns may have temporary lactose intolerance because their body hasn’t started producing lactase, however it soon wears off


aka lactose intolerance

How does one inherit alactasia?

How does alactasia affect my body?

- with alactasia one cannot digest the lactose found in dairy products and it ends up being fermented by bacteria, which causes a lot of stomach pain and bloating- alactasia is produced by a problem with the small intestine

-congential alactasia is an autosomal recessive disorder in the mutation of the LCT gene-the ability to digest lactose during adulthood is dependent on variations in the MCM6 gene. The variations that allow for lactose digestion during adulthood are autosomal dominant
