Originally, it was only natural for people to lose their ability to digest milk sugar after their childhood. Because in winter food was sparse in Northern Europe and people had to drink milk to consume enough calories a tolerance to lactose was developed with time. Many scientists believe the theory that a gene mutation made milk tolerable for some population groups.
Lactose intolerance can be genetic or it can develop over time. The genetic intolerance, also called primary lactose intolerance, is a rare condition where a newborn does not produce lactose from birth. Worldwide, adult-onset lactose intolerance is the most common form.
Lactose Intolerance Self Test is a send-in sampling kit which is used for testing in the event of a suspected lactose intolerance. The test determines the concentration of hydrogen and methane in exhaled air after lactose exposure. The process is pain-free and can be done easily from home. The sample is analysed in the specialised diagnostics laboratory.
