Let me tell you something that will blow your mind! As a functional medicine doctor, here’s what I changed when the Coronavirus hit:


Yeah, that’s right! I continued to do the same things I did before the virus.

From my perspective, my immune system is always under attack from all kinds of pathogens. Viruses, bacteria, parasites and fungus are all out to ruin my life 24/7, 365 days out of the year. Sounds pretty pessimistic doesn’t it? I haven’t always been so pessimistic, but after seeing enough lab reports on my patients, I began to understand how a weak immune system can lead to all kinds of health problems, including vulnerability to pathogens.


I need to bring up some uncomfortable realities.

Exposure to pathogens is going to happen. No matter what we do to try to prevent it, we are exposed to all kinds of pathogens. I’m all for washing hands and keeping our environment clean. (However, some of the cleaners out there are so toxic I’m not sure if the benefit is worth the toxicity. I have the test results to prove it. There are safe and effective alternatives.)

These measures help REDUCE exposure. However, nothing we do can prevent all exposure to pathogens. We do not eat sterile food, we do not drink sterile fluids, we do not breathe sterile air, we do not live in sterile homes or workplaces, or shop in sterile stores, or interact with sterile people.

I do understand the concern to reduce exposure. In our office we are not treating anyone with any symptoms of fever or upper respiratory tract distress. If anyone working in our office thinks they are getting sick they will not be allowed to work. We are disinfecting our treatment rooms after every patient. All surfaces that get touched like counter-tops are disinfected every hour. We are meeting with our functional medicine patients over the phone and internet.

All that being said, we cannot escape pathogens. They are everywhere. I’ve seen patients with infections that shock me. Giardia (a serious parasite), Salmonella (a serious bacteria), Norovirus (a serious virus) are some examples of pathogens I find in patients on a regular basis. Most of these patients have no idea how they even contracted their infections.

Exposure to a pathogen does not mean that we will get sick.

Just because you are exposed to a virus (including the Coronavirus) does not mean you will get sick! I live in a house with 9 other humans, I work on people (literally), and I spend a minimum of 15 minutes with each of my chiropractic patients in a small room, breathing the same air, and touching their bodies as I work on them. Furthermore, I am exposed to everything, but I am rarely sick. Especially in my house, when someone is sick, everyone is exposed, but not everyone gets sick.

So. If we are going to be exposed to pathogens, and if exposure does not equal illness, why do we get sick?

The issue isn’t the Coronavirus, (bacteria, fungus, parasite) but the immune system!

One of the things I want to know about my patients is how healthy their immune system is. The tests tell the story. Often I see a depleted, weakened immune system which can lead to a multitude of problems. The kinds of things that lead to a sick immune system are:

When I have a patient with a weak immune system, I look for these kinds of things and fix them with the right supplements and proper nutrition. And guess what happens! Their immune system starts to recover! Here is an example:

A Functional Medicine Example

A 51-year-old female came to me for help with the following problems:

  • Frequently sick
  • Fatigue
  • Brain Fog
  • Anxiety/Depression
  • Indigestion
  • Irritable Bowel Syndrome

The testing we did on this patient uncovered several serious issues:

Now, isn’t that quite a list? When you look at this list, can you imagine why this patient might be experiencing the problems she is having? Is it any wonder that she is frequently sick?

My patient was very committed to her health and stuck with her specific treatment plan and follow up testing. Over time, her symptoms began to disappear and the testing showed that the root problems were no more! This patient recently wrote to me:

This is the first year I can remember that I didn’t get really sick over the winter even with travel and stress.
So thank you for all that you have done to help me. I really feel like I’m in a good place healthwise right now!!!

The Functional Medicine Approach to Coronavirus

The functional medicine approach to infections like the Coronavirus starts with identifying and correcting the problems with the “foundational” systems. As with this patient, we look for chronic infections, toxins, nutrient deficiencies, and poor diet and lifestyle choices. If any of these exist they will impair the immune system.

Functional medicine is all about getting to the root of the problem. This approach is obviously not something that can be done quickly. Fixing some of these problems can take months.

One of the real lessons of the Coronavirus is that we need to be healthy! There will ALWAYS be pathogens out to get us! Once this virus has come and gone there will be another new bug. If we are healthy and our immune systems are robust, there isn’t anything to be worried about.

Start with your diet!

A great place to start is to improve your diet. I want to encourage you that increasing your intake of fresh, organic produce is extremely beneficial. During the panic buying of the Coronavirus, we’ve noticed that while all the pasta, bread and canned foods were gone from the shelves, there is still plenty of fresh, organic produce available. These clean, fresh vegetables will supply important nutrients for our immune systems.

If you are worried about getting sick from COVID-19, one of the best things you can do is start working with me to get healthy! I can help you even if you don’t live here in Arizona.

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.
