Hereditary food intolerances are common and can seriously affect quality of life. This genetic test studies specific variants in the genes responsible for the digestion of lactose and fructose:
Lactose intolerance: occurs due to reduced activity of the enzyme lactase, which is necessary to break down lactose, the sugar in milk. Its deficiency causes symptoms such as bloating, diarrhea, abdominal pain, or gas after consuming dairy products.
Hereditary fructose intolerance: is a rare but serious disorder caused by mutations in the aldolase B gene, which prevent proper metabolism of fructose. It can cause severe abdominal pain, vomiting, hypoglycemia, and if untreated, liver and kidney problems.
Unlike acquired intolerances, these genetic forms accompany the individual throughout life. Early detection allows for dietary adjustments and prevention of major complications.
