People with lactose intolerance can not tolerate milk sugar (lactose) - because their body is unable to digest the sugar. Accordingly, we also speak of a lactose intolerance or lactose intolerance.
lactose is a so-called Double sugar (Disaccharide) - it consists of the two sugar units slime sugar (galactose) and dextrose (glucose). In the digestive enzymes break down in the gut, the food on - the lactose is so broken down into its two components. The smaller sugar units arrive on the lining of the small intestine into the blood. The body uses it mainly for energy. The lactose intolerance is caused by a Lack of lactase.
lactase is the special enzyme that breaks down the milk sugar in the gut as a cutting tool into its building blocks. The ruling on lactose intolerance lactase deficiency However, results in the lactose undigested passes into the large intestine. This triggers the typical lactose intolerance symptoms: In the large intestine various intestinal bacteria ferment the milk sugar into fatty acids and gases, but also to other metabolites which intestinal mucosa irritate can.

Meanwhile, living with lactose intolerance has also become easier, as many lactose-free foods are on the market - for example, lactose-free milk and cream and lactose-free yogurt, cheese and curd. Some cheeses (especially older cheese) also contain naturally little or no lactose. Here it is worth looking at the product packaging, because in some cases, these cheeses are declared as lactose-free.
