Lifestyle and Environmental Causes—and Solutions—for Rheumatoid Arthritis

Meditation is the path to a healthier brain

Rheumatoid arthritis (RA) is an autoimmune condition in which the immune system mistakenly attacks the synovial lining of the joints. The synovial lining is a layer of connective tissue that lines the joints and is responsible for secreting synovial fluid into the joint cavity to help joints move smoothly.

The joints most commonly affected in rheumatoid arthritis are the hands, knees, or ankles. The affected joints are typically painful and swollen, and moving the joints can be difficult. The joints may look red and feel warm to the touch. Over time, chronic inflammation can lead to bone erosion and joint deformity. The disease can also affect some people’s skin, eyes, heart, lungs, and circulatory systems.

Treatment for rheumatoid arthritis typically includes medications that manage symptoms and slow disease progression. Rheumatoid arthritis is considered to be incurable.

What Causes Rheumatoid Arthritis?

However, if you’ve been diagnosed with rheumatoid arthritis or any autoimmune condition, it is important to know the following:

“Bodies do not just start attacking themselves for no reason. The human body is incredibly well-designed after millions of years of evolution. It has backup systems and redundancies, like any highly engineered piece of machinery. It does not easily or suddenly break on its own.” – Dr. Steven Phillips, Chronic, p. 158.

In other words, autoimmune conditions don’t arise for no reason or simply bad luck—they’re triggered by something. What that something is may seem like a mystery, but if you can discover the cause of your rheumatoid arthritis, you can potentially reverse the disease process. You will need to be your own health advocate in this discovery process, as most doctors can’t take the time to investigate all the possible triggers of your disease, nor are most experienced enough with autoimmune diseases to do so.

A Complicated Condition with Complicated Solutions

It’s also important to know that a number of different factors can cause and contribute to the same set of symptoms. For example, one person’s rheumatoid arthritis could be caused by an underlying infection, while another person’s rheumatoid arthritis could be caused by diet. There can easily be multiple factors at work, all contributing to the development of rheumatoid arthritis. So, when embarking on this discovery process, you’ll be most successful if you remain open-minded and explore all possible contributing factors.

In this article, I’ll discuss some of the most common contributing factors for developing rheumatoid arthritis: infections, diet and gut health, nutrient deficiency, stress, and genetic factors.

The Role of Infection in Rheumatoid Arthritis

Since the 19th century, when rheumatoid arthritis started to become more prevalent, there has been speculation on the role of viral and bacterial infections in developing the condition. In 1947, doctors observed that rheumatoid arthritis patients who were treated with tetracycline (a broad-spectrum antibiotic) experienced relief from their symptoms. These cases were presented at the Seventh International Congress on Rheumatic Diseases in 1949. Unfortunately, the immunosuppressive benefits of cortisone in arthritis patients were presented at the same conference, and the findings on antibiotics were ignored. This paved the way for the treatment approach for rheumatoid arthritis that would be relied upon for the next five decades: suppress the immune system.

Is Lyme Disease a Culprit?

In 1972, researchers published a study of 51 patients living in and around Lyme, Connecticut, who developed what appeared to be rheumatoid arthritis. They discovered that the patient’s symptoms developed after being bitten by an insect carrying a certain type of bacteria, Borrelia burgdorferi. The condition was subsequently named “Lyme arthritis.” However, it is now known as Lyme disease because cardiac, dermatologic, and neurological symptoms can also occur with the infection.

Lyme disease is one of many bacterial, viral, and parasitic infections that can potentially lead to rheumatoid arthritis. But Lyme is a very common one; the CDC estimates that there are approximately 300,000 new cases of Lyme disease per year in the United States. Sadly, the majority of these cases go undiagnosed and untreated due to unreliable lab testing. In fact, the CDC admits that their testing protocol fails to identify 90 percent of Lyme disease cases.

Lyme disease is known as “The Great Imitator” because its symptoms can mimic more than 300 other diseases, including rheumatoid arthritis, osteoarthritis, lupus, fibromyalgia, chronic fatigue syndrome, cardiovascular disease, multiple sclerosis, Parkinson’s disease, Alzheimer’s disease, and amyotrophic lateral sclerosis (ALS). But Dr. Steven Phillips and Dana Parish, authors of the book Chronic, call Lyme disease and related infections “The Great Cause.” They believe that calling Lyme an imitator is misleading to patients, as Lyme or a related infection (collectively referred to as Lyme+) is often the actual cause of their health condition.

Other Infections That May Cause Rheumatoid Arthritis

Just some of the infections associated with developing rheumatoid arthritis include Borrelia burgdorferi (Lyme disease), Citrobacter, E. coli, Klebsiella, Mycoplasma, Proteus, Porphyromonas, Epstein-Barr virus, Hepatitis C, Parvovirus B19, and retroviruses.

Scientists have also found a link between rheumatoid arthritis and oral infection with the bacteria Porphyromonas gingivalis. Patients with rheumatoid arthritis have higher levels of anti-P. gingivalis antibodies than people without rheumatoid arthritis, and autoantibodies related to RA are higher in people with P. gingivalis infections than those without.

Why Can Infections Cause Rheumatoid Arthritis?

Why can infections cause rheumatoid arthritis? There are multiple mechanisms, which include:

Molecular mimicry: When an antigen (foreign substance) is structurally similar to a self-antigen (a cellular protein in the body), the immune system can mistakenly attack the self-antigen along with the antigen.

Epitope spreading: When the immune response extends its attack beyond the original epitope (the part of an antigen molecule to which an antibody attaches itself). This allows the immune system to attack multiple pathogens.

Polyclonal lymphocyte activation: When the immune system response includes the production of many different antibodies by many different B cells to target the same antigen, the chances of one of those antibodies attacking self-antigen increases.

Bystander activation: When inflammatory mediators such as cytokines trigger the activation of T cells without the T cells recognizing an antigen.

Viral persistence: When the virus is not cleared by the immune system but remains in certain cells of the infected person.

Learn About Infections and Autoimmune Diseases

If you want to learn more about the role of chronic infections in developing autoimmune diseases, I highly recommend reading the book Chronic by Dr. Steven Phillips and Dana Parish. This book is an absolute must-read for anyone with rheumatoid arthritis. 

Whether or not you have reason to believe you might have an underlying infection, it’s important to get tested for the infections most commonly associated with rheumatoid arthritis. As you’ll learn in Chronic, many tests are unreliable and often give false-negative results when the patient is actually positive. Also, testing is often done too early in the disease process, before the patient’s immune system has built a response sufficient to show up on a test. You should seek out a doctor who specializes in treating long-term infections.

The Role of Gut and Diet in Rheumatoid Arthritis

Natural products for healthy bowel. Top view. Concept of diet as important to autoimmune diseases.

Research shows that many rheumatoid arthritis symptoms improve when gluten is removed from the diet. Gluten is a protein in wheat, barley, rye, and other common grains. Gluten is added to many processed foods, beauty products, medications, and supplements.

The rates of celiac disease and non-celiac gluten sensitivity have been rising steadily for the past several decades due to the new type of wheat being grown, which has been hybridized and deamidated. While statistics vary, some studies suggest that up to 30 percent of the population is now gluten-sensitive, and somewhere between 50 to 99 percent of people with celiac disease or gluten sensitivity are never diagnosed.

What Is Leaky Gut Syndrome?

When gluten reaches our gut, it’s broken down into the proteins gliadin and glutenin. In gluten-sensitive people, the immune system sees gliadin as dangerous and produces antibodies to attack it. In people with celiac disease, those anti-gliadin antibodies also cause gut permeability (leaky gut), which allows toxins, microbes, food particles, and the anti-gliadin antibodies to leak out of the intestines and travel through the body.

Anti-gliadin antibodies often attack other things in the body besides just gliadin and can trigger the immune system to attack its own tissues. This is how autoimmune conditions result from gluten sensitivity and celiac disease. The presence of anti-gliadin antibodies is associated with rheumatoid arthritis, Hashimoto’s thyroiditis, IgA-nephritis, psoriasis, sickle-cell anemia, and hepatic disorders. Gluten sensitivity and celiac disease can also lead to neurological symptoms, including dysregulation of the autonomic nervous system, cerebella ataxia, hypotonia, developmental delay, learning disorders, depression, migraine, and headache.

Can a Gluten-Free Diet Help?

In one small study, 18 out of 18 patients with rheumatoid arthritis improved on a gluten-free diet, often after just two weeks on the diet. Another small study showed that removing gluten from the diet can improve symptoms of rheumatoid arthritis, even in patients who are resistant to conventional drug therapies. A larger study of 121 rheumatoid arthritis patients found that anti-gliadin antibodies were more prevalent in rheumatoid arthritis patients than in the general population.

Dairy Consumption and Rheumatoid Arthritis

Research consistently shows that dairy consumption is linked to increased autoimmune symptoms. Casein accounts for 80 percent of the protein in milk, whey accounts for about 20 percent, and other minor proteins like lactoglobulin, lactalbumin, serum albumin, immunoglobulins, and glycomacropeptides comprise the rest. Casein, in particular, is difficult to digest for many people and often leads to an inflammatory autoimmune response. Dairy consumption has been linked to a number of autoimmune conditions, including rheumatoid arthritis, type 1 diabetes, inflammatory bowel disease, multiple sclerosis, and others.

Some studies show that removing gluten, dairy, and meat from the diet reduces the symptoms of rheumatoid arthritis. In a study of 66 patients, 40.5 percent of the rheumatoid arthritis sufferers who ate a vegan, gluten-free diet for nine months or more improved, and their improvement was consistent with a reduction in anti-gliadin and anti-beta-lactoglobulin antibodies. Another study of 40 rheumatoid arthritis patients showed that removing gluten, dairy, and meat from the diet for three months significantly reduced inflammation and pain.

How to Know Whether Gluten and/or Dairy are Problematic

Since gluten and dairy are consistently associated with an increase in autoimmune symptoms, it is often advised that anyone with an autoimmune condition do an elimination diet in which gluten and/or dairy are removed from the diet completely for at least one month. If you feel significantly better without gluten and/or dairy in your diet, or if you feel noticeably worse after reintroducing either one, then you are likely sensitive to one or both.

Insulin Resistance and Rheumatoid Arthritis

Insulin resistance and hyperinsulinemia are hallmarks of type 2 diabetes, but they’re surprisingly common among rheumatoid arthritis sufferers as well. When synovial joint fluid is exposed to high levels of insulin, immune cells invade the area, causing inflammation in the joint and reduction of the production of synovial fluid. Dr. Benjamin Bikman writes in Why We Get Sick, “Rheumatoid arthritis is heavily associated with insulin resistance to the point that those individuals who experience the worst inflammation also experience the greatest insulin resistance.”

Some research shows that the insulin resistance experienced in rheumatoid arthritis sufferers is actually caused by the inflammation associated with rheumatoid arthritis instead of the other way around. However, in most people, insulin resistance and hyperinsulinemia are the direct result of the food we eat. Diets high in added sugar and refined carbohydrates raise our insulin levels and lead to insulin resistance over time. To learn more about how diet leads to insulin resistance and hyperinsulinemia, I highly recommend Dr. Jason Fung’s phenomenal books, The Obesity Code and The Diabetes Code.

Gut Bacteria and Rheumatoid Arthritis

A significant body of research shows that the bacterium Proteus mirabilis, which is responsible for urinary tract infections, is strongly correlated with and potentially causative of rheumatoid arthritis. P. mirabilis infection can lead to inflammation and joint damage in rheumatoid arthritis by the mechanism of molecular mimicry. This means that when the body produces antibodies to P. mirabilis, these antibodies may mistakenly attack cells in the synovial tissues that are similar in structure to P. mirabilis

Some researchers recommend that rheumatoid arthritis sufferers be treated early with anti-P. mirabilis antibiotics as well as biological agents. You can also address this infection with diet; P. mirabilis feeds on refined carbohydrates, which may be one reason why rheumatoid arthritis symptoms tend to improve on diets that restrict or eliminate refined carbohydrates.

Research Links Gut Bacteria with Rheumatoid Arthritis

In a study of 114 people, 75 percent of rheumatoid arthritis patients had the bacteria Prevotella copri in their intestines as opposed to just 21 percent of healthy controls. Higher levels of P. copri correlated with reduced Bacteroides and a loss of beneficial microbes in rheumatoid arthritis patients. 

Other research shows that people with rheumatoid arthritis have higher levels of antibodies that target P. copri in their bloodstream. While P. copri helps to digest fiber and is commonly found in the gut, it is also linked to insulin resistance, high blood pressure, and inflammation. Researchers suggest that P. copri may bind to the mucous lining of the gut and escape into the bloodstream, provoking an immune response. The bacteria may also invade the joints and cause inflammation and damage to the synovial lining.

Can Therapeutic Fasting Help?

Intermittent fasting eight hour feeding window concept. Diet and eating healthy food.

Some research has been carried out to test the efficacy of therapeutic fasting, both intermittent and extended, for relieving rheumatoid arthritis. Fasting can benefit rheumatoid arthritis sufferers for several reasons.

If any foods are consumed that contribute to rheumatoid arthritis symptoms, fasting immediately and completely removes them. This can lead to rapid improvement of symptoms. However, research shows that if rheumatoid arthritis patients resume their normal diet after their fast, their symptoms return. Some research suggests that the positive effects of the fast can be prolonged by following the fast with a vegetarian diet or a more healthful diet than they had previously been eating.

While research has not yet shown this benefit for rheumatoid arthritis specifically, fasting can allow harmful gut bacteria to die off. Fasting also significantly improves insulin resistance by lowering insulin levels, which, as previously mentioned, tend to be higher in people with rheumatoid arthritis.

Fasting, especially extended fasting, has also been shown to “reset” the immune system. While fasting, the body eliminates old or damaged immune system cells through a process called autophagy and regenerates new cells.

If you want to learn more about therapeutic fasting, I highly recommend reading The Complete Guide to Fasting by Dr. Jason Fung.

The Role of Vitamin D Deficiency in Autoimmune Disease

Many nutrient deficiencies have been observed in patients with rheumatoid arthritis, including folic acid, vitamin C, vitamin D, vitamin B6, vitamin B12, vitamin E, folic acid, calcium, magnesium, zinc and selenium. Of these, vitamin D deficiency may be the most problematic and common. Approximately 40 percent of Americans are deficient in vitamin D, and this deficiency has been strongly linked to autoimmune conditions.

Researchers believe that vitamin D has immunomodulatory effects on cells of the immune system, particularly T lymphocytes, and on the production and action of several cytokines. A meta-analysis of 15 studies that included a total of 1,143 rheumatoid arthritis patients and 963 controls found that vitamin D levels are significantly lower than average in patients with rheumatoid arthritis, that vitamin D deficiency is more common in rheumatoid arthritis patients than controls and that lower levels of vitamin D correlate with worse rheumatoid arthritis symptoms.

How Does Vitamin D Help?

Black slate table with product rich in vitamin D and omega 3. Written word vitamin D by white chalk. Concept of Vitamin D for Rheumatoid Arthritis treatment and prevention,

Some research shows that supplementation with vitamin D early in the disease process can help reduce symptoms and improve treatment results. In experimental animal models of rheumatoid arthritis, vitamin D prevents disease development. Vitamin D can prevent autoimmune disease in two ways: “It inhibits the development of T-cells and their production of active agents (called cytokines) that initiate the autoimmune response; and/or it encourages the production of other T-cells that oppose this effect.” The China Study, p. 191.

Your healthcare provider can order a 25-hydroxyvitamin D blood test if you’re interested in determining whether you’re deficient. And to boost your vitamin D levels, you can:

  • Eat foods rich in vitamin D, including oily fish and egg yolks, and foods such as cereals and dairy products with vitamin D added to them (however, whole, unprocessed foods are always best!).
  • Supplement with vitamin D (liquid is easiest to absorb) or take cod liver oil, one tablespoon of which contains as much vitamin D as three servings of oily fish.
  • Expose your skin to the sunlight for a short period of time every day. This allows a substance in your skin to react with UVB rays and produce vitamin D.
  • Check your medications. Some pharmaceuticals can block the absorption of vitamin D.

The Role of Stress in Rheumatoid Arthritis

Stress management techniques. Group of people practicing yoga in park. Concept of stress reduction to reduce inflammation.

Research shows that stress is a factor in many autoimmune conditions. In fact, retrospective studies show that up to 80 percent of patients experience unusual emotional stress before the onset of their autoimmune condition. And since having a chronic disease is stressful, there can be a vicious cycle in which stress worsens the condition, leading to more stress.

A study of 2,490 Vietnam veterans found that those with post-traumatic stress disorder had a 174 percent increased risk of developing an autoimmune condition, including rheumatoid arthritis, psoriasis, type 1 diabetes, and autoimmune thyroid disease. A study of 41 women with rheumatoid arthritis found that an increase in disease activity, including joint pain and inflammatory biomarkers, was associated with an increase in the number of stressors during that week and the previous week. Other studies have shown that the initial onset of rheumatoid arthritis was associated with stress at work and that chronic mild stress increases inflammation and disease activity.

How Does Stress Create Inflammation?

Chronic Inflammation and how it affects the body and concept of problems that can create autoimmune diseases like rheumatoid arthritis.

When we experience stress, neurotransmitters, hormones, and immune cells send a message from the brain to the rest of the body to prepare for an attack. Inflammatory chemicals called cytokines are released, which can trigger the onset of an autoimmune condition or flare-up of a current condition. Chronic stress is especially damaging to the body, as there is no periodic relief from the stress response and resulting inflammation.

Researchers suggest that since the endocrine and nervous systems play a pivotal role in the onset and aggravation of rheumatoid arthritis, treatment should include stress management and behavioral intervention.

The Role of Genetic Factors in Rheumatoid Arthritis

Like other autoimmune conditions, certain genes can increase your risk of developing rheumatoid arthritis. Research suggests that genes, the environment, and the interaction between the two determines who develops rheumatoid arthritis.

Researchers have found over 100 genetic changes that occur more frequently in rheumatoid arthritis patients than in the general population. Many of these genetic changes involve the immune system, which is responsible for the inflammation present in rheumatoid arthritis.

More Research on Genetic Factors

A Swedish study found that first-degree relatives of people with rheumatoid arthritis were three times more likely to develop rheumatoid arthritis compared to controls. The body of research on the genetics of rheumatoid arthritis shows that genes play a significant role in one’s susceptibility to developing rheumatoid arthritis. However, not everyone with rheumatoid arthritis has the genes that are known to be risk factors for rheumatoid arthritis, and having one or more of the genetic risk factors does not mean that one will get rheumatoid arthritis.

So, while understanding the genetic risk factors definitely doesn’t give us the whole picture of someone’s risk of developing rheumatoid arthritis, there are benefits to learning more about the genes involved in the disease. Understanding which genes are involved can help scientists identify new targets for treatments and potentially predict which treatment each patient is likely to respond best to based on their genetics.

Medications vs. Lifestyle Changes

If you have rheumatoid arthritis, you should explore all possible lifestyle and environmental factors that could be contributing to your condition. While the medications commonly used to manage rheumatoid arthritis may relieve your symptoms, they do nothing to help you recover from the disease. Most medications come with a long list of side effects, which include weakening of the immune system, increased risk of certain cancers and infections, organ damage, and heart failure. Changing your lifestyle and navigating the healthcare system can take time, patience, and persistence, but it’s well worth it in the long run.
