ME/CFS is a condition in which severe fatigue is central, often in combination with complaints such as muscle pain, concentration problems and reduced recovery after exercise.

Research shows that the gut microbiome of people with ME/CFS may differ from that of healthy individuals. In addition, there are indications that bacterial substances from the intestine can enter the body more easily due to increased permeability of the intestinal wall. This could potentially contribute to the symptoms seen in ME/CFS.

Fibromyalgia is characterized by persistent pain in muscles, tendons, and connective tissue. In addition, fatigue, sleeping problems and concentration complaints are common. The exact cause is not yet fully known.

It is striking that many people with fibromyalgia also have intestinal complaints, such as complaints that fit with irritable bowel syndrome (IBS). In addition, there is evidence that disturbances in the gut microbiome and bacterial overgrowth in the small intestine are more common in people with fibromyalgia.

Autoimmune diseases arise because the immune system recognizes and attacks the body's own cells and substances as foreign. This can cause inflammation and various complaints.

The gut microbiome plays an important role in the regulation of the immune system. Research shows that changes in the composition of the microbiome can affect the way the immune system responds. Among other things, it looks at the phenomenon of molecular mimicry, in which bacterial substances resemble the body's own structures and may play a role in autoimmune reactions.

Multiple sclerosis (MS) is a condition in which the protective layer around nerves in the brain, spinal cord and optic nerves is affected. This can cause complaints with movement, feeling, seeing and balance.

In people with MS, differences have been found in the composition of the gut microbiome. Researchers see, among other things, changes in bacteria involved in regulating the immune system. As a result, interest in the possible role of the microbiome in the development and progression of MS is growing.

Rheumatoid arthritis is a chronic inflammatory disease in which joints can become painful, stiff, and swollen. The immune system plays an important role in this.

The gut microbiome helps in the tuning of the immune system. In people with rheumatoid arthritis, changes have been found in both the gut microbiome and the oral cavity microbiome. Several studies suggest that these changes may contribute to inflammatory processes. In addition, some studies show that support for the microbiome can contribute to improving symptoms and quality of life.

In terms of tone and length, these versions fit in well with the rewritten texts for IBS, IBD, ulcerative colitis and SIBO. They are also formulated a little more carefully than the current texts, which usually fits better with medical content on a public website.
