Gut Microbiome Test XL – our largest gut health test

Gut Microbiome Test XL is our most comprehensive gut health test where you can test for leaky gut, yeast overgrowth (including Candida) and beneficial gut bacteria, such as Lactobacillus and Bifidobacterium. The test also analyses your digestion, inflammatory markers and much more.

Our laboratory calls this test the “Gut Test for Stressed People“. Stress not only affects our energy and general mood, but can also cause digestive issues. During stress, the sympathetic nervous system is activated and the parasympathetic is down-regulated, and with that certain functions such as digestion are then down-regulated. A gut that is out of balance can affect the rest of the body, and the expression that you cannot think when the stomach does not work has now been given its own definition – “The Gut Brain connection”. Studies on this show how the stomach affects the brain and how possible intestinal imbalances can be linked to a number of different diseases such as depression, autism, Parkinson’s and Alzheimer’s.

What does leaky gut mean?

Leaky gut is used in layman’s terms to describe a condition in which the lining of the intestines becomes damaged and hyperpermeable, which can allow small particles such as undigested food, bacteria and other substances to penetrate the mucosa and enter the blood. Since these particles should not be there in the first place, our immune system believes that it is being attacked and responds by attacking various tissues in the body. Depending on where this occurs, it can lead to various diseases, ranging from hypothyroidism / hyperthyroidism to psoriasis, multiple sclerosis, allergies, IBS, fatigue and many other autoimmune diseases.

A leaky gut can, if left untreated, lead to a range of symptoms such as food intolerances, stomach issues, fatigue, brain fog, weakened immune system, skin problems, joint problems, depression and much more. Since it can be difficult for the average person to know if you have a leaky gut or not, you can have this issue for a long time before understanding that it can be the cause behind a number of different health problems. Testing for leaky gut is thus extremely important in several different diseases and ailments.
