Lactose Intolerance Up to 90 percent of South Asians may be lactose intolerant. Lactose intolerance, which is due to the inability to digest milk sugars, is a common disorder caused by a deficiency of the lactase enzyme in the digestive system. Lactose intolerance is three times more common in South Asians than in other populations. 1  Symptoms. 2  Diagnosis.

Lactose Intolerance  [en EspaÃ±ol] Lactose intolerance means the body cannot easily digest lactose, a type of natural sugar found in milk and dairy products. This is not the same thing as a food allergy to milk.ost people with this type of lactose intolerance can eat some milk or dairy products without problems. Sometimes the small intestine stops making lactase after a short-term illness such as the stomach flu or as part of a lifelong disease such as cystic fibrosis.

What Causes Lactose Intolerance? Lactose intolerance is the inability to break down a type of natural sugar called lactose. Lactose is commonly found in dairy products, such as milk and yogurt. A person becomes lactose intolerant when his or her small intestine stops making enough of the enzyme lactase to digest and break down the lactose.

- How Race And Age Factor In Lactose Intolerance. Lactose Intolerance is a common problem - about 65 percent of the human population has it. And while it can’t be cured, it’s rarely dangerous and you can manage lactose intolerance.

What causes Lactose Intolerance? Generally, lactose intolerance most commonly runs in families and is related to one’s family’s genes. Lactose intolerance can also be brought on by infections, chemotherapy, penicillin reactions, surgery, pregnancy, or from the avoidance of dairy products for a prolonged period of time.

- The most common form of lactose intolerance is caused by the body’s inability to produce lactase, the enzyme that digests lactose, the sugar found in milk. Early in life, the body generally produces plenty of lactase – which is very important for infants, since they get nearly all of their nutrition from milk.

- Lactose intolerance is the inability to digest a sugar called lactose that is found in milk and dairy products. Normally when a person eats something containing lactose, an enzyme in the small intestine called lactase breaks down lactose into simpler sugar forms called glucose and galactose.

- Lactose intolerance is an impaired ability to digest lactose, a sugar found in milk and other dairy products. Lactose is normally broken down by an enzyme called lactase, which is produced by cells in the lining of the small intestine.actose intolerance in adulthood is caused by gradually decreasing activity (expression) of the LCT gene after infancy, which occurs in most humans. LCT gene expression is controlled by a DNA sequence called a regulatory element, which is located within a nearby gene called MCM6.

What Is Lactose Intolerance? Lactose intolerance is caused by the body's inability to digest milk sugar, or lactose. In order to break lactose down into simple sugars, or monosaccharides, the body must produce the enzyme called lactase, which is produced in the small intestine.

What is Lactose Intolerance? What is it? This is sensitivity to foods that contain lactose. Lactose is a sugar most often found in dairy products. It is a common problem and can affect anyone, but is most common among Native American, Asian, and black people. This is not a food allergy, just the sugar present is dairy products, lactose, cannot be absorbed.

- Lactose intolerance is the inability to digest lactose, the sugar primarily found in milk and dairy products. It is caused by a shortage of lactase in the body, an enzyme produced by the small intestine that is needed to digest lactose.ymptoms of lactose intolerance occur when there is not enough lactase being produced by the body to digest the lactose consumed. Symptoms of lactose intolerance include nausea, cramps, gas, bloating, or diarrhea within 30 minutes to 2 hours after consuming milk or dairy products.

Many non-dairy products contain casein (a milk derivative), listed on the ingredient labels. 2  Some specialty products made with milk substitutes (i.e., soy-, nut-or rice-based dairy products) are manufactured on equipment shared with milk. 3  Some meats may contain casein as a binder. 4  Check all labels carefully.

How Do I Know If Iâm Lactose Intolerant? Lactose intolerance, refers to individuals who are unable to digest lactose (or sugars from dairy products) due to a lactase (an enzyme produced in the small intestine) deficiency. Without enough lactase, the body is unable to break down lactose into glucose to be absorbed into the bloodstream for energy.

Lactose Woes Pregnancy after Gastric Reduction Yogurt, although made from milk, is often well tolerated by people who have lactose intolerance because yogurt bacteria produce their own lactose-digesting enzyme of actase. If you have a strong reaction to lactose, you will have to become an avid labelreader. Look for words, such as whey, lactose, nonfat milk solids, buttermilk, malted milk, margarine, and sweet or sour cream.

Most Dairy Reactions Are Not Lactose Intolerance Lactose intolerance is defined by a person having a deficiency in the enzyme lactase. Lactase is needed in order to digest the sugar component in milk called lactose. Many people are lactose intolerant, but millions more have an immune reaction to dairy. Unfortunately, most people don’t recognize that there is a difference between the two issues.

Lactose intolerance Babies' bodies make the lactase enzyme so they can digest milk, including breast milk. 1  Babies born too early (premature) sometimes have lactose intolerance.  Children who were born at full term often do not show signs of the problem before they are 3 years old.

- Not having enough lactase in the body is the cause of lactose intolerance. Primary lactose intolerance. This type develops in people who were once able to fully digest lactose. It is the most common type. Almost all infants make enough lactase to fully digest lactose found in human milk and infant formulas.

Lactose Intolerance Lactose intolerance is a condition that results from a deficit of lactase (lactase deficiency), an enzyme produced by the cells lining the small intestine. Lactase is necessary to digest lactose, the natural sugar found in milk. Lactase breaks down lactose (milk sugar) into two simpler forms of sugar called glucose and galactose, which are then absorbed into the bloodstream.

Are You Lactose Intolerant? Lactose is found in milk and other dairy products. It consists of two simple sugars, glucose and galactose. You can become lactose intolerant at any time in life, but it’s most common in adulthood. It’s estimated that 30 to 50 million Americans are lactose intolerant.

What is Lactose Intolerance? Lactose intolerance refers to digestive disturbances caused by not having enough intestinal lactase, the enzyme needed to break down lactose--the sugar found naturally in milk and milk products. If lactose is not digested, it can cause gas and stomach cramps.

What Are Crohnâs Disease and Lactose Intolerance? Lactose intolerance, also known as lactase deficiency, is due to a person’s inability to produce enough (or any) of the lactase enzyme in the small intestine. This enzyme digests lactose, a sugar found in dairy products. Lactase breaks down the lactose into a pair of simpler sugars: glucose and galactose.
