Hypolactasia & lactose intolerance among three ethnic groups in Malaysia.

[Frequency and clinical overview of hypolactasia among children, adolescents and students of Szczecin schools].

INTRODUCTION Adult type hypolactasia is the most common non allergic abnormal reaction to food. Its frequency increases with age. Hypolactasia creates the risk of decreased milk consumption, which could be the cause of lowered bone density, osteoporosis and fractures. The aim of the research was to estimate the frequency of hypolactasia among Szczecin's citizens. MATERIAL AND METHODS 200 rand...

Frequency of LCT -13910C>T single nucleotide polymorphism associated with adult-type hypolactasia/lactase persistence among Brazilians of different ethnic groups

BACKGROUND Adult-type hypolactasia, the physiological decline of lactase some time after weaning, was previously associated with the LCT -13910C>T polymorphism worldwide except in Africa. Lactase non-persistence is the most common phenotype in humans, except in northwestern Europe with its long history of pastoralism and milking. We had previously shown association of LCT -13910C>T polymorphism...

Lactose Intolerance Quick Test CLINICAL TRIAL Performance of the LACTOSE INTOLERANCE Quick Test in Diagnosis of Adult-Type Hypolactasia Among Dyspeptic

Oral Administration of Exogenous Lactase in Tablets for Patients Diagnosed with Lactose Intolerance Due to Primary Hypolactasia.

Background Primary hypolactasia is a common condition where a reduced lactase activity in the intestinal mucosa is present. The presence of abdominal symptoms due to poor absorption of lactose, which are present in some cases, is a characteristic of lactose intolerance. Objective Evaluate the efficacy of a product containing exogenous lactase in tablet form compared to a reference product wit...

Hypolactasia: a common enzyme deficiency leading to lactose malabsorption and intolerance.

Adult‑type hypolactasia (lactase nonpersistence or lactase deficiency) is the most common enzyme deficiency leading to lactose intolerance and primary lactose malabsorption. Clinical presentation of the condition includes symptoms resulting from bacterial fermentation of undigested lactose in the colon, which gives rise to gas bloat, increased motility, and loose stools. Diagnosis of the diseas...
