Two screening tests are used to screen infants affected with galactosemia—the Beutler's test and the Hill test.Galactose is converted into glucose by the action of three enzymes, known as the The only treatment for classic galactosemia is eliminating lactose and galactose from the diet.
The condition, which is also called lactose malabsorption, is usually harmless, but its symptoms can be uncomfortable.Too little of an enzyme produced in your small intestine (lactase) is usually responsible for lactose intolerance. Typically, those with fructose malabsorption can consume No treatment can cure hereditary fructose intolerance.

Infants affected by galactosemia typically present with symptoms of lethargy, vomiting, diarrhea, failure to thrive, and jaundice. ; 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. Milder forms of the condition may cause discomfort and affect a person’s quality of life, but lifestyle changes can help. A person may develop hereditary fructose by obtaining the gene from both of their parents. This involves ingesting 1.8 ounces (50 grams) of lactose and testing for elevated levels of hydrogen in the breath, which are caused by bacteria fermenting lactose in the colon (Interestingly, up to 20% of people with lactose malabsorption will not test positive, and some people who test positive will have no symptoms at all (This is because not all people with malabsorption have lactose intolerance.Lactose intolerance is defined by the presence of reported symptoms, and that depends on how sensitive a person is to the effects of malabsorption, as well as the amount of lactose in their diet (Treatment of lactose intolerance usually involves restriction or avoidance of high-lactose foods such as milk, cheese spread, cream and ice cream (Additionally, people often tolerate fermented milk products such as cheese and yogurt better, so these foods may help people meet their calcium needs without causing symptoms (Lactose intolerance is very common, affecting up to 70% of people worldwide.The most common symptoms include stomach pain, bloating, diarrhea, constipation, gas, nausea and vomiting.There have been reports of other symptoms, such as headaches, fatigue and eczema, but these are rarer and not well established. The gas produced from the fermentation of lactose is odorless.It can be another indication of lactose intolerance, though it’s a much rarer symptom than diarrhea.As bacteria in the colon ferment undigested lactose, they produce methane gas. Therefore, the frequency and severity of symptoms can vary significantly between individuals (Finally, the bloating, distension and pain may result in nausea or even vomiting in some people. Affected children can have serious, irreversible effects or even die within days from birth. As a result, they have diarrhea, gas and bloating after eating or drinking dairy products. People with fructose malabsorption cannot properly absorb or digest fructose.

A person should tell a doctor about any family history of genetic diseases. Healthline Media does not provide medical advice, diagnosis, or treatment. Infants, who get all their nutrition from milk, need lactase.As children replace milk with other foods, the amount of lactase they produce normally drops, but usually remains high enough to digest the amount of dairy in a typical adult diet. The fructose then accumulates in the liver and kidneys, causing serious and potentially fatal complications, such as liver and The symptoms that a person experiences may depend on the type of fructose intolerance. These include diet, other kinds of malabsorption, medications, infections and inflammatory bowel diseases (The fermentation of lactose in the colon increases the production of the gases hydrogen, methane and carbon dioxide (In fact, in people with lactose intolerance, the colon microflora become very good at fermenting lactose into acids and gases.
