Revitalize Your Immune System – A Functional Medicine Perspective

How can you protect yourself from getting sick? Well, to revitalize your immune system from a functional medicine perspective, we first have to accept that 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 environments 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.

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.

From a functional medicine perspective, our 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.

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


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!


A 51 year old female came to me for help for 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 health wise right now!!!

If you are worried about getting sick, 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 started using red light therapy shortly after giving birth to my second child. I was desperate to head off any post partum depression this time around since I struggled with it with my first. It has helped even out my hormones so much! I've used it for a month so far, going on two and truly I feel amazing. I haven't been as tired even though my sleep is terrible and I feel in control of my crashing pregnancy hormones. This has truly been a God send for me!!
