The Link Between Joint Pain And Intestinal Bacteria

Can Intestinal Bacteria Cause Joint Pain? According to several studies, these microbes affect the immune system and thus trigger problems in other parts of the body.
The link between joint pain and intestinal bacteria

Rheumatoid arthritis is caused by the failure of the cartilage, which leads to inflammation and joint pain. Although researchers have identified some risk factors that could trigger this health problem, experts are still unsure of the direct cause of this disease. In the search for an exact cause, a group of researchers has focused on a possible link between joint pain and intestinal bacteria.

Recent studies have shown that intestinal bacteria can cause joint pain, including pain caused by rheumatoid arthritis.

Furthermore, they are related to diseases that alter the functions of the immune system, which can lead to other chronic problems.

Is there a link between joint pain and intestinal bacteria?

In a study from 2013, Dr. José Scher – a rheumatologist at New York University – found that patients with rheumatoid arthritis (arthritis) more often had intestinal bacteria called Prevotella copri , than those who did not suffer from the disease.

In another study published in October of the same year, Scher found that those with psoriatic arthritis had lower levels of important bacteria in the gut.

These studies are part of an experiment conducted by researchers around the world to understand and explain the role that microbiomas (the mass of microbes that live in the gastrointestinal tract) play in human general health.

It is estimated that the intestinal flora is composed of over 1000 different species of intestinal bacteria that together weigh between 1 and 2.5 kg. In recent years, researchers have tried to prove that these organisms have a lot to do with human health; some trigger disease, while others protect the body.

Intestinal bacteria affect the immune system

Veena Taneja, an immunologist at the Mayo Clinic in Rochester, Minnesota. Confirms that “it becomes clearer with each study that these microbes can affect the immune system and contribute to diseases beyond the gut. There is a link between joint pain and intestinal bacteria. ”


The researchers were surprised by the findings which proved that the intestinal bacteria affect the immune system much more than previously thought.

In recent decades, cases of autoimmune disorders have increased. Many microbial scientists are convinced that our modern lifestyle and the changes it has caused in the microbiome ecosystem are partly responsible for this problem. 

Prevotella copri bacteria can be responsible for joint pain

These microbes affect the health of the intestine, where two thirds of the body’s immune cells are located. During digestion, the gastrointestinal tract has to contend with a constant stream of unknown microbes that are ingested along with food and drink.

In order to do its job properly, the gut has developed a comprehensive immune system. Which extends to other organs outside the intestine. The immune cells that live in the gut have the ability to activate inflammation in cells throughout the body, including those in the joints.

According to José Scher Prevotella copri can cause an  immune reaction.  Which later spreads to other tissues and causes joint pain. Another theory is that the beneficial microbes are displaced and thus weaken the immune system .

The latter theory is one of the most supportive, as a study showed that patients with high levels of Prevotella copri  also had reduced levels of Bacteroides fragilis, which is a useful bacterium that supports the immune system.

The results of these studies have led to the start of new studies. To be able to create strategies for using bacteria as a treatment for immune diseases.

In fact, health experts already recommend probiotics (good bacteria) for the restoration of the intestinal flora and the treatment of health problems such as acne, insomnia and other problems related to intestinal health.

So it shows that there is actually a link between joint pain and intestinal bacteria, try probiotics if you suffer from it.
