Rheumatoid Arthritis and Ankylosing Spondylitis Have a Common Curable Cause

Rheumatoid ArthritisIf you suffer from Rheumatoid Arthritis or Ankylosing Spondylitis, I’ve got great news for you. Both of these diseases share a common curable cause. The cause is so well documented in the literature that it boggles the mind that this is not common knowledge in the medical community.











Both Rheumatoid Arthritis (RA) and Ankylosing Spondylitis (AS) can be triggered by bacterial infections most often found in the intestinal tract. These bugs have names like Klebsiella, Citrobacter, Proteus, Porphyromonas and Yersinia.

Genetics determine who will develop RA or AS from these infections

Here’s the deal. Most people who get these infections don’t get Rheumatoid Arthritis or Ankylosing Spondylitis. People who have the HLA-B27 gene and get a Klebsiella infection can develop Ankylosing Spondylitis. A person with the HLA-DR4 gene who gets a Klebsiella, Citrobacter, Proteus, Porphyromonas or Yersinia infection can develop Rheumatoid Arthritis.

These bacteria trigger changes in the gene, which causes the person’s immune system to attack normal healthy cells, resulting Rheumatoid Arthritis or Ankylosing Spondylitis. As long as a person is fighting the bad bug, the influence on the gene will continue. However, if the pathogen can be eliminated, the negative effect on the gene will cease, and the immune system will stop attacking the body.

On a side note, this same sort of gene/pathogen relationship is what causes some people to become very sick from mold or Lyme.

Leaky Gut

Often these bad bugs will damage the intestinal tract and lead to a disorder called leaky gut syndrome. Even without the bad genetics, a damaged intestinal tract will lead to all sorts of inflammation and aberrant immune function. In my patients, I rarely find one of these pathogens without gut damage. With these infections it’s important to test for a leaky gut and treat it if it’s damaged.


These pathogens can also cause Small Intestinal Bacterial Overgrowth(SIBO). This is important to know because bacteria in the small intestine often do not show up on a stool analysis. So proper testing is key to diagnosis and treatment.

Frequently I find that my patients with SIBO also have a leaky gut due to the damage the bacteria causes. So again, testing is so important to getting a patient well.

 A Comprehensive Stool Analysis

A Comprehensive Stool Analysis is one of the most important tests to run in patients with Rheumatoid Arthritis or Ankylosing Spondylitis. This test will often not only identify the offending pathogen that is responsible for the RA or AS, but will also show what will kill that pathogen. How cool is that?!

In functional medicine we ask the question, “What caused the problem?”

If you suffer from Rheumatoid Arthritis or Ankylosing Spondylitis, I’m sure the thought, “What caused this?” has crossed your mind. For years you did not have RA or AS and then one day BAM you got it. All the typical treatments of traditional medicine do nothing to treat the underlying causes of these terrible diseases. If you want to get to the root of Rheumatoid Arthritis or Ankylosing Spondylitis, I’d love to help. It’s what I love doing for my patients.

I have been using the Hyperbaric Oxygen Therapy for the last few weeks and It has helped me so much. I struggle quite a bit with work related stress. When I'm in the chamber I feel completely relaxed, so much so that I can bring my laptop inside and work without stressing. The calmness I feel in the chamber lasts for the remainder of the day as well. I have found too, the more consistent I am with sessions throughout the week the better I feel. The office staff seems well trained in running the tanks too, so I feel safe. I see Dr. Kilcup as well for my brain and gut health. Until now, I don't think I've ever known what "normal" or "healthy" feels like. Thank you all, sincerely!

Darrell is highly knowledgeable and really gets to the root of the problem. Unlike a lot of doctors, Darrell doesn't just throw prescriptions at issues. He will test and test - digging for the cause and then working on fixing the issue. He and his staff are professional, courteous, and a joy to be around.

I am very grateful to have found Dr. Kilcup and be his patient for the last couple of years. He has helped me restore my health back after being exposed to toxic mold for years. He helped identify and treat all of my symptoms I was experiencing and address the root problem. I was looking for the right person who could help me heal with natural therapies and supplements and Dr. Kilcup was the perfect fit. Every appointment and session was necessary and one step towards all the progress I made. Dr. Kilcup is a great functional medicine doctor who was also an advocate for my own health and well-being. I never received any care or attention to detail from other Doctors in past experiences except with Dr. Kilcup. Anyone who is seeking a holistic path towards healing or improving their own health should see him.
