    Congenital lactase deficiency is related to, but different from, lactose intolerance common in adults. Lactose intolerance involves the same enzyme, lactase, and the same gene, LCT. [thinkgenetic.com]

    Babies who cannot properly digest food they are given will often develop gas, abdominal pain, and other uncomfortable symptoms. [pediacare.com]

    Lactose intolerance is the clinical symptoms associated with lactose malabsorption, including diarrhea, bloating and flatulence, abdominal pain, and gaseous accumulation in the intestine in response to a dose of lactose. [ansci.illinois.edu]

    Increased intestinal gas may occur 30 minutes to hours after ingestion of the sugar, and the distension of bowel wall leads to crampy abdominal pain. [clinicaladvisor.com]

    Diagnosis Dietary history of the patient who are complaining flatulance, abdominal pain, diarrhoea.  Familial history of the patient.  Check whether the patient has underwent partial gastrectomy and other related procedures.  Tests – stool acidity [slideshare.net]

  • Nausea

    Symptoms Abdominal bloating and cramps  Flatulence  Diarrhoea  Nausea  Borborygmi (rumbling stomach)  Vomiting (particularly in adolescents).  7. [slideshare.net]

    Some of the most characteristic symptoms of lactose intolerance are: stomachache, nausea, diarrhea and gas and its effects vary from person to person in intensity. [tellmegen.com]

    Symptoms of lactose intolerance include gas, bloating, nausea, abdominal cramping and diarrhoea. [glutenfreecentral.com.au]

    In congenital lactase deficiency, a very rare genetic disorder (affecting fewer than 50 patients in the world, mainly in Finland), lactase activity is drastically reduced or non-existent. (1) Infants with this disease can experience symptoms such as nausea [yogurtinnutrition.com]

    Symptoms include: Bloating Flatulence Diarrhea Nausea Vomiting Abdominal pain or cramps Gurgling and rumbling sounds from the abdomen Recommended Links: Ranciaro A et al. (2014). [dnainthenews.com]

  • Loss of Appetite

    One symptom that typically is not seen, however, is loss of appetite. In fact, most infants who have CLD have an exceptionally good appetite and even appear hungry and eager to eat much of the time. [brighthub.com]

Without treatment, they may become dehydrated, lose weight and experience malnutrition. Symptoms usually start during the first week of life when an infant is given breast milk or formula (which will contain lactose) for the first time. [thinkgenetic.com]

The onset of symptoms typically occurs in early infancy and the course and prognosis vary depending on the underlying cause. 1 Congenital lactose deficiency is caused by very low levels or the absence of lactase-phlorizin hydrolase (commonly known as [analesdepediatria.org]

Prognosis The prognosis of lactose intolerance is excellent, with many people experiencing improvement of symptoms with dietary restrictions. [myvmc.com]

Pathophysiology The lactase enzyme is located in the brush border (microvilli) of the small intestine enterocyte. The enzyme splits and hydrolyzes dietary lactose into glucose and galactose for transport across the cell membrane. [aafp.org]

Secondary Lactase Deficiency Secondary lactase deficiency implies that an underlying pathophysiologic condition is responsible for the lactase deficiency and subsequent lactose malabsorption. [pediatrics.aappublications.org]

Its deficiency prevents the hydrolysis of lactose and causes osmotic diarrhoea when the child starts breastfeeding. 2,3 At first it was believed that CLD was a severe form of lactose intolerance with early onset. 4 But while both disorders are due to [analesdepediatria.org]

Prevention In only one of the three types of lactose intolerance can this disorder be prevented. This can be done by preventing the mentioned diseases, some of which are also congenital. [tellmegen.com]

There was a good correlation between the C/C(-13910) genotype and low lactase activity ( How can disaccharidase deficiences be prevented? Primary causes of disaccharidase deficiencies cannot be prevented. [clinicaladvisor.com]

Congenital lactase deficiency Congenital lactase deficiency is a very rare, autosomal recessive genetic disorder that prevents lactase expression from the first feed.  Congenital lactose intolerance is serioue disorder in which the infants may fail to [slideshare.net]

Thus, diseases that markedly speed up transit of lactose through the small intestine prevent lactose from being fully digested and absorbed, leading to a misdiagnosis of lactose intolerance. [rxlist.com]
