How C1 Affects the Vagus Nerve in Infants
The C1 vertebra is the topmost bone in the spine, sitting just beneath the skull. It surrounds and protects the brainstem, where the vagus nerve (cranial nerve X) originates. The vagus nerve is a critical part of the parasympathetic nervous system, which controls rest, digestion, immune response, and regulation of internal organs.
In infants, the birth process (even in a smooth delivery) can cause misalignment or tension at the C1 level. This can create pressure or irritation around the brainstem and vagus nerve.
đź§’ Problems That May Occur in Infants When C1 Irritates the Vagus Nerve:
Colic & Excessive Crying
Poor vagus nerve signaling can affect digestive function, making it harder for babies to soothe or digest comfortably.
Reflux (Spitting Up, GERD)
The vagus nerve helps control the esophageal sphincter. When disrupted, it can allow stomach acid to move upward more easily.
Difficulty Nursing or Latching
Tension at the upper cervical spine can affect the baby's ability to turn their head, latch evenly, or coordinate sucking and swallowing.
Constipation or Irregular Bowel Movements
Since the vagus nerve regulates digestive motility, its dysfunction can slow the gut down.
Poor Sleep or Restlessness
Irritation at the brainstem can keep the baby’s nervous system in “fight or flight,” rather than the calming “rest and digest” mode.
Weakened Immune Function or Frequent Ear Infections
Since the vagus nerve influences immune regulation, dysfunction may play a role in recurring infections or immune system challenges.
đź‘¶ How Chiropractic Can Help
Gentle chiropractic adjustments focused on C1 can reduce irritation around the brainstem and vagus nerve—restoring normal nerve function and helping the baby feel, sleep, and digest better.
