The Vagus Nerve: The Missing Link in Your Child's Health

Parents in Colorado Springs are facing challenges they never imagined. Despite special diets, supplements, medications, or countless therapies, many children continue to battle persistent digestive problems, restless nights, anxiety, and focus issues that make daily life feel like a constant struggle.

Autism now affects one in 31 children, and over a million new ADHD diagnoses were made in the past few years alone. Chronic conditions impact nearly 40% of kids in the United States. These alarming statistics reflect more than individual health problems—they point to a nervous system that’s under enormous strain.

As Dr. Jason Cahill explains, “What we’re seeing clinically is a generation of children whose nervous systems are chronically stuck in fight-or-flight mode. Their bodies are in a constant state of stress response which severely impacts the function of the vagus nerve.”

Understanding the Vagus Nerve

The vagus nerve is the longest and most complex cranial nerve, extending from the brainstem through the neck and into the chest and abdomen. It connects the brain to the heart, lungs, digestive system, immune system, and more.

Known as the primary pathway of the parasympathetic nervous system, it helps regulate rest, digestion, healing, and emotional balance. But when it becomes dysfunctional, the effects ripple throughout the entire body. Children may experience chronic digestive issues, lowered immunity, emotional outbursts, or difficulty calming themselves after stress.

Through its impact on heart rate variability and respiratory patterns, vagus nerve dysfunction can even affect a child’s ability to calm down, regulate stress, or avoid meltdowns.

How Stress and Early Life Events Affect Kids

Many vagus nerve problems begin even before birth. Maternal stress hormones can cross the placenta and influence fetal nervous system development. Birth interventions like C-sections, forceps, or vacuum extraction can cause physical trauma to the delicate upper neck and brainstem region, where the vagus nerve originates.

Early childhood factors such as repeated antibiotic use, environmental toxins, excessive screen time, or emotional stress can further compromise vagus nerve function. Over time, these layers of stress overwhelm the developing nervous system, leaving children stuck in fight-or-flight mode and unable to regulate themselves effectively.

A Neurologically Focused Approach

Conventional medicine often addresses symptoms one by one—digestive problems, anxiety, sleep issues—without connecting them back to a shared root cause. Neurologically focused chiropractic care takes a different approach by looking directly at nervous system function.

At our office, INSiGHT Scans measure how well a child’s nervous system, including vagus nerve activity, is functioning. These non-invasive scans evaluate heart rate variability (HRV), one of the most reliable markers of vagal tone. With this objective data, we can identify patterns of dysfunction and create a personalized plan to restore balance.

As Dr. Jason says, “If your child is stuck in stress mode and struggling with focus, digestion, sleep, sensory issues, behavior, or emotional regulation challenges, it’s time to stop guessing and start testing.”

Helping Kids Regain Balance

When the vagus nerve functions properly, the body can calm itself, regulate digestion, support the immune system, and handle stress with resilience. For parents who have tried everything and still feel out of answers, addressing nervous system health may be the breakthrough that changes their child’s trajectory.
