What is a person lacking who is lactose intolerant?
People with lactose intolerance or lactase deficiency cannot metabolize lactose properly; they lack lactase, an enzyme required in the digestive system to break down lactose. Patients typically experience bloating, flatulence, and diarrhea after drinking milk.Lactose is a sugar that is found most notably in milk. Lactose intolerance is characterized by abdominal cramps and diarrhea after consumption of food that contains lactose (milk, ice cream).eople with adequate amounts of lactase can break down lactose into glucose and galactose (a type of sugar) which are then absorbed into the bloodstream. In people with low levels of lactase, the lactose is not broken down and does not absorb into the bloodstream, instead it moves into the large intestine (colon). Lactose intolerance is the inability of adults and children to digest lactose, a sugar found in milk and to a lesser extent dairy products, causing side effects.It is due to a lactase deficiency, or hypolactasia.he principal symptom of lactose intolerance is an adverse reaction to products containing lactose (primarily milk), including abdominal bloating and cramps, flatulence, diarrhea, nausea, borborygmi, and vomiting (particularly in adolescents). These appear one-half to two hours after consumption. Lactose is a type of sugar found in milk. Lactase is a protein, an enzyme that is produced in the small intestine-it breaks down lactose. Individuals with lactose intolerance do not produce enough lactase.People with adequate amounts of lactase can break down lactose into glucose and galactose (a type of sugar) which are then absorbed into the bloodstream.In people with low levels of lactase, the lactose is not broken down and does not absorb into the bloodstream, instead it moves into the large intestine (colon).eople with adequate amounts of lactase can break down lactose into glucose and galactose (a type of sugar) which are then absorbed into the bloodstream.

Lactose intolerance is a common problem. It happens when your body does not have enough lactase, which is an enzyme produced in the small intestine. Lactase is necessary to digest lactose – the natural sugar found in milk and other dairy products.In the intestines, undigested lactose leads to the buildup of gas.Within 30 minutes to 2 hours after eating dairy products containing lactose, people with lactose intolerance start to develop stomach cramps and diarrhea.actase is necessary to digest lactose – the natural sugar found in milk and other dairy products.

If you have lactose intolerance, you may love milk, but your body doesn't -- and it lets you know that when you have too much. You might have symptoms like cramps after a bowl of cereal or gas after an ice cream treat. Lactose is the main sugar in milk and other dairy products.If you have lactose intolerance, you can't digest it well. Lactose intolerance is not curable, but there are many ways to cut your symptoms and feel better.ou might have symptoms like cramps after a bowl of cereal or gas after an ice cream treat.

Lactose intolerance is the inability to efficiently convert lactose into glucose and galactose, a reaction catalyzed by the enzyme lactase. (A rule of thumb for enzyme nomenclature is that many enzyme names typically take most of the name of their substrate and slap an -ase at the end.).actose intolerance is a digestive disorder common to dogs. Lactose, the sugar found in milk is composed of glucose and galactose. Lactose intolerance. When a person has a lactose intolerance it means their body is unable to digest lactose.

Not everyone suffers from this condition. 1 Lactose intolerance is caused by a deficiency of the intestinal enzyme lactase that splits lactose into two smaller sugars, glucose and galactose, and allows lactose to be absorbed from the intestine. 2  The primary symptoms of lactose intolerance are diarrhea, flatulence (passing gas), and abdominal pain.
