Lactose intolerance is distinct from milk allergy, an immune response to cow's milk proteins. They may be distinguished in diagnosis by giving lactose-free milk, producing no symptoms in the case of lactose intolerance, but the same reaction as to normal milk in the presence of a milk allergy. A person can have both conditions.
Galactosemia is sometimes confused with lactose intolerance, but galactosemia is a more serious condition. Lactose intolerant individuals have an acquired or inherited shortage of the enzyme lactase , and experience abdominal pains after ingesting dairy products, but no long-term effects.
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.
Sucrose and lactose are called disaccharides because they are made from two simple sugars, and are broken down into these simple sugars during digestion. Sucrose is broken down into glucose and another simple sugar called fructose, and lactose is broken down into glucose and galactose. As a result, lactose, sucrose and other compounds made from ...
While awaiting confirmatory testing for classic galactosemia, the infant is typically fed a soy-based formula, as human and cow milk contains galactose as a component of lactose. [4] Confirmatory testing would include measurement of enzyme activity in red blood cells, determination of Gal-1-P levels in the blood, and mutation testing.
The unabsorbed lactose reaches the large intestine, where resident bacteria use it for fuel, releasing hydrogen, carbon dioxide and methane gases. These gases are the cause of abdominal pain and other symptoms. [38] [41] Lactose intolerance does not cause damage to the gastrointestinal tract. [42]
This is an autosomal recessive disorder and infants that can’t break down lactose have trouble with breastmilk, and develop diarrhea starting from birth. Sometimes, even those with lactase-persistence can develop temporary lactose intolerance as a result of infection or inflammation in the small intestine.
Galactose epimerase deficiency has an autosomal recessive pattern of inheritance.. Galactose epimerase deficiency is an autosomal recessive disorder, [5] which means the defective gene is located on an autosome, and two copies of the defective gene - one from each parent - are required to inherit the disorder.
