How can I help you?

My core areas of expertise are mainly in the field of complementary gastroenterology, in particular the following topics:

Irritable bowel syndrome (IBS)

Irritable bowel syndrome is one of the most common functional disorders of the gastrointestinal tract and affects a great many people. In addition, 50-90% of patients experience anxiety disorders or depression.

SIBO - Small Intestinal Bacterial Overgrowth

Bacterial overgrowth in the small intestine (SIBO) is the most common cause of irritable bowel syndrome (IBS).

Leaky Gut Syndrome

Leaky gut means that the barrier function of the mucous membrane of the small intestine is disturbed. As a result, bacteria and toxins from the intestine can enter the bloodstream and promote systemic inflammation.

Mast cell associated diseases

In mast cell dysfunction, also known as MCAS, mast cells in the body are overly activated, resulting in the release of numerous bioactive substances, such as histamine.

Intestinal parasitoses

Parasitoses also exist in our latitudes and are not rare. It's just not being looked for enough (anymore). In the intestinal tract, they can lead to numerous symptoms. Especially severe courses should lead to a closer diagnosis in this area.

Preventive all-round check-up

We carry out preventive all-round check-ups to optimise health. Among other things, assessment of individual cardiovascular risk, genetic analysis of detoxification capacity, vitamin and mineral analyses, and much more.
