4 analyzed indicators for your intestinal health

Intestinal flora compared with age.

The intestinal microbiome develops in its species diversity until adolescence and then remains relatively stable in composition over a long period of time. In old age, changes occur again, i.e. in many people the species diversity decreases and the proportions of certain bacterial species increase. These can have a negative effect on the immune system, among other things.


Enterotypes (Greek: enteron = intestine) are common colonization variants of the bacterial intestinal flora. A distinction is made between three enterotypes, which are related to dietary habits and are each dominated by a different group of bacteria: Bacteroides, Prevotella or Ruminococcus. Each group affects our health differently, e.g. efficiency of nutrient processing or vitamin production.

Species diversity (Shannon index)

Species diversity (also diversity) refers to the quantitative species richness of your microbiome. The more species-rich the microbiome, the more stable its condition. It is important that these are bacterial species that have positive effects on metabolism. The Shannon Index (SI) is the measure of species richness and should always be evaluated together with the Dysbiosis Index.

Intestinal flora balance (dysbiosis index).

The dysbiosis index describes the quality of the intestinal bacteria species found with regard to positive and negative properties for the body. The higher the dysbiosis index, the higher the proportion of bacterial species with negative properties.

4 analysed risk areas

Risk of intestinal diseases

The most common diseases of the intestine include irritable bowel syndrome, inflammatory bowel diseases (including Crohn's disease, ulcerative colitis), adenomas (precancerous lesions) and colon carcinomas.

Risk for cardiovascular diseases

Close links are known between the microbiome and diseases such as arteriosclerosis, myocardial infarction, chronic myocardial insufficiency, and stroke.

Risk of metabolic diseases

Common metabolic diseases include adult-onset diabetes (diabetes mellitus type 2), lipid metabolism disorders, and obesity. The diet in Western industrialized nations plays a major role in the development of these diseases.

Risk of disturbance of the gut-brain axis

There is continuous communication in both directions between the nerve cells of the intestine, which are influenced by bacterial substances of the intestinal flora, and the nerve cells of the brain. Accordingly, the condition of the intestinal flora can also be partly responsible for mental and neurological diseases.
