The Antibiotic Time Bomb: How Chiropractic Supports a Resilient Immune System | San Antonio TX

Antibiotic overuse is driving resistance worldwide. Dr. Dan Foss explains how your immune system is your real defense—and how chiropractic care, including his unique CMRT visceral work, supports immunity from the inside out.

The Antibiotic Time Bomb: How Chiropractic Supports a Resilient Immune System | San Antonio TX

If you catch every cold that comes around, or you find yourself reaching for antibiotics several times a year, I want to share something important with you. Your body has a built-in defense system far more powerful than any antibiotic — if you give it the right support. In 23 years of practice, I have watched patients transform their health not by fighting infections harder, but by building an immune system resilient enough to prevent them in the first place.

The irony is that our modern approach to infection — bombarding bacteria with antibiotics — is slowly turning the tables against us. Let me walk you through what is actually happening, why chiropractic matters, and how I use specialized techniques like CMRT and SOT to help your body do what it was designed to do: protect itself.

The Hidden Cost of Antibiotic Overuse

We prescribe antibiotics at an astonishing rate. Hundreds of millions of prescriptions are dispensed every year in the United States alone, and here is the truth that most patients never hear: most of those prescriptions are unnecessary. Viral infections — the common cold, flu, most sore throats — do not respond to antibiotics at all. Yet they are prescribed anyway.

Each time you take an antibiotic, something major happens inside your body that goes largely unmentioned. The antibiotic does not just kill the bacteria causing your infection. It also kills the beneficial bacteria living in your gut — the same bacteria that train your immune system, produce essential vitamins, protect against harmful pathogens, and keep your whole digestive system in balance.

This collateral damage is profound. Your gut microbiome — the community of trillions of microorganisms living in your intestines — is where approximately 70 percent of your immune system lives and trains. Wipe out that community with an antibiotic, and you have just disarmed one of your greatest defenses.

What makes this worse is that antibiotic overuse is creating resistant bacteria. These are pathogens that have evolved the ability to survive antibiotics, making infections harder to treat and more dangerous. The very tool that once saved lives is becoming less effective with each passing year.

Why Your Immune System Is Your Real Defense

Your immune system is not a backup plan. It is your primary defense against infection — and it is far more sophisticated than antibiotics.

When you encounter a virus or bacteria, your immune system does not just attack blindly. It identifies the threat, mounts a specific response, remembers that pathogen for the future, and even teaches other cells how to recognize it next time. This is why you rarely get the same infection twice. Your body learned.

Antibiotics are a sledgehammer. They kill bacteria — both the bad and the good — without discrimination. Your immune system is a precision weapon. Given the right conditions, it outperforms any antibiotic because it adapts, remembers, and builds lasting protection.

The real question is: what creates the conditions for a strong immune response?

Three things stand out. Sleep — during deep sleep, your immune system ramps up production of infection-fighting white blood cells. Stress management — chronic stress suppresses immune function through elevated cortisol. Nervous system balance — your autonomic nervous system directly controls how aggressively your immune cells respond.

This third point is where chiropractic enters the picture.

The Nervous System-Immunity Connection

Your autonomic nervous system has two branches: the sympathetic (fight-or-flight) and the parasympathetic (rest-and-digest). When you are in sympathetic dominance — which is where many of us live thanks to chronic stress, poor posture, and spinal misalignment — your immune system actually gets suppressed. Your body is too busy preparing to run from a tiger to build white blood cells.

The parasympathetic nervous system is where immunity thrives. When you are truly relaxed, your body invests in long-term survival — which includes a robust immune response.

Here is what I see in practice: patients stuck in chronic sympathetic dominance catch colds frequently, recover slowly, and often end up on repeat courses of antibiotics. Patients with balanced, parasympathetic-dominant nervous systems get sick less often and bounce back quickly when they do.

Sacro-Occipital Technique (SOT) is my foundational tool for restoring autonomic balance. SOT does not just adjust bones. It resets the nervous system by working with the cranium, sacrum, and pelvis — the three pillars of nervous system regulation. When these are properly aligned, parasympathetic tone increases. You relax. Your immune system turns back on.

The Gut-Immunity-Spine Connection: What CMRT Does

Here is where something remarkable happens: the gut and the spine are not separate systems. They are linked through a complex network of neural reflexes.

About 80 percent of your gut-associated lymphoid tissue — the immune cells stationed in your digestive tract — is reflexively connected to your spine, particularly your thoracic and lumbar regions. This is not poetic. It is anatomy.

CMRT (Chiropractic Manipulative Reflex Technique) is a specialized technique that addresses visceral reflex points — pressure points on the spine that correspond to organs, glands, and tissues throughout your body. The gut, liver, and ileocecal valve (a critical gatekeeper in your intestines) all have CMRT reflex points.

When I work with these reflex areas, I am essentially reactivating your body's ability to regulate digestion, maintain the integrity of your gut barrier, and keep your beneficial bacteria thriving. This is something almost no other chiropractor does. It is a skill that took years of advanced training, and it is one of the most powerful tools I have for supporting immune function from the inside out.

After antibiotics particularly, CMRT and nutritional support can help rebuild your microbiome more effectively than almost anything else I have seen.

When Antibiotics Are Absolutely Appropriate

Let me be clear: I am not anti-antibiotic. I am anti-overuse.

There are absolutely situations where antibiotics are necessary and life-saving. A serious bacterial infection — strep throat with complications, a deep wound infection, meningitis, severe pneumonia — these are times when antibiotics are the right choice.

What I am saying is this: most of the time, your body can handle the threat. And each time you avoid an unnecessary antibiotic, you preserve your microbiome, strengthen your immunity, and reduce the risk of resistance.

I work alongside MDs and pediatricians across the Stone Oak, Castle Hills, Alamo Heights, and Helotes areas. When a patient needs antibiotics, I refer them. When they do not, I help them build the immune resilience to avoid needing them.

Building Real Immunity: The Practical Steps

Your immune system responds to what you do every day. Here is what I recommend to every patient:

Sleep: Prioritize 7 to 9 hours of quality sleep. This is where immune memory gets encoded.

Stress management: Chronic stress is an immune suppressant. Meditation, breathing work, time in nature — whatever helps you access parasympathetic tone.

Nutrition: A diet rich in whole foods, fiber (to feed your beneficial bacteria), and minimal processed sugar. Your microbiome depends on it.

Movement and posture: Poor posture keeps you in sympathetic dominance. Regular chiropractic care restores alignment and nervous system balance.

Regular chiropractic care: This is the foundation. SOT and CMRT work together to keep your spine aligned, your nervous system balanced, and your immune system primed.

What to Expect from Immune-Focused Care at Pura Vida

When you come in for immune support, here is what happens:

We do a comprehensive assessment of your spinal alignment, your autonomic nervous system status, and your overall health history. We look at your gut health, your stress patterns, and your lifestyle factors. Then we design a care plan that might include SOT adjustments, CMRT work, and recommendations for sleep, nutrition, and stress management.

Many patients see improvement in how often they get sick within the first 4 to 6 weeks. Others notice they recover faster when illness does occur. Some patients simply feel better — more energy, better digestion, improved mood — because their nervous system is no longer in crisis mode.

We are bilingual — English and Spanish — and we serve patients from Stone Oak, Castle Hills, Alamo Heights, Helotes, and throughout San Antonio.
