What Colic and Reflux Are Telling You

September 1, 2026

There is nothing quite like the sound of your baby crying inconsolably for hours on end. You have fed them, changed them, rocked them, and checked everything you can think of, and still, nothing seems to help. If this sounds familiar, you are not alone. Colic and reflux affect a staggering number of infants, and yet most parents are left feeling confused, exhausted, and without real answers. What if the crying was not just "something babies do," but rather a signal that something deeper is going on inside your baby's body? That is exactly the question that functional and holistic medicine is beginning to answer.

What Is Colic, and Why Does It Happen?

Colic is defined as excessive, unexplained crying in an otherwise healthy infant. Doctors use what is commonly called the "Rule of Threes" to identify it: crying for at least three hours a day, at least three days a week, for at least three weeks. It affects somewhere between 20 and 25 percent of all babies, making it one of the most common concerns in early infancy.

A colicky baby tends to cry most intensely in the evening hours. The cry is often high-pitched and piercing, and the baby may pull their legs up toward their stomach, clench their fists, flush red in the face, and wrinkle their brow. One of the most telling signs is that these babies almost always find relief after passing gas. That detail alone tells us something important: the discomfort is largely digestive in nature.

The conventional medical world has long struggled to explain exactly why colic happens. The honest answer is that no one knows for certain. What functional and holistic medicine offers, however, is a broader lens through which to look at the problem, one that considers the whole baby rather than just the symptom.

What Is Reflux, and How Is It Different?

Reflux is simply the backward flow of stomach contents up into the esophagus. Most parents know it as "spitting up," and it typically begins around two weeks of age, once a baby is eating enough volume to create pressure in the stomach.

There is also something called silent reflux, which can be trickier to identify. In silent reflux, the stomach contents travel up the esophagus but do not always come out of the mouth. Instead, the baby may swallow it back down, or it may travel into the throat, nasal passages, or even the voice box, causing irritation without the obvious sign of spit-up.

It is worth understanding the difference between GER and GERD. GER, or gastroesophageal reflux, is the normal, common version. It may be messy, but the baby is not particularly bothered by it. GERD, or gastroesophageal reflux disease, is when the reflux is causing the baby genuine discomfort and distress. That distinction matters when trying to understand what your baby is experiencing.

How Are Colic and Reflux Connected?

Though colic and reflux can appear to be entirely separate issues, they are actually closely related. They share many overlapping symptoms and, from a functional medicine perspective, often share overlapping root causes as well. One key difference is in feeding behavior: babies with reflux often resist feeding or stop frequently during a feed, while colicky babies tend to feed normally.

Understanding that these two conditions are connected is important because it shifts the focus away from treating each symptom in isolation and toward looking at the whole picture of what is happening in the baby's developing body.

The Real Toll on Families

It would be impossible to talk about colic and reflux without acknowledging what they do to the entire family unit. The impact goes far beyond sleepless nights. Research has linked persistent infant crying to increased rates of postpartum depression, significant marital stress, early termination of breastfeeding, and parental anxiety. The exhaustion that comes from caring for a baby in constant distress is profound, and it deserves to be taken seriously.

Recognizing this is not about adding guilt to an already difficult situation. It is about understanding that colic and reflux are not trivial concerns, and that parents who are struggling deserve real information and real support.

Warning Signs That Require Immediate Medical Attention

Before exploring the holistic perspective, it is essential to acknowledge that not all infant crying is colic. There are certain warning signs that should prompt an immediate visit to your pediatrician. These include vomiting that is green or yellow, bloody, or happening more than five times a day; changes in stool including blood or mucus; an abnormal temperature; crying that is constant with very few calm periods; unusual sleepiness or weakness lasting more than six hours; and poor weight gain. Always rule out serious medical conditions first.

Why Conventional Approaches Often Fall Short

The most commonly prescribed medications for infant reflux are acid-blocking drugs. While these are widely used, the research tells a more complicated story. Reviews of the available literature suggest that medical interventions for infantile colic and reflux are generally ineffective, and the potential for side effects in developing infants is a real concern. Some of these medications have only been studied in adults, meaning their effects on an infant's immature digestive system are not fully understood.

What Functional Medicine Asks Instead

Functional medicine approaches infant colic and reflux by asking a different question. Rather than asking what medication can suppress the symptom, it asks why the symptom is happening in the first place. This shift in thinking opens the door to a much more comprehensive understanding of what is going on in your baby's body.

The Role of Diet

One of the first areas functional medicine examines is diet. For breastfeeding mothers, what you eat directly influences what your baby receives. Cow's milk protein is one of the most commonly identified dietary contributors to infant digestive distress. Both North American and European pediatric gastroenterology societies recommend a trial elimination of cow's milk protein as one of the first steps when reflux is present. For formula-fed babies, switching to a hydrolyzed formula may also be worth exploring with your healthcare provider.

Caffeine, nicotine, and certain other substances found in breast milk have also been linked to infant irritability, making maternal diet an important piece of the puzzle.

The Gut Microbiome

Perhaps one of the most fascinating areas of research in infant health right now is the gut microbiome. Babies who experience colic and reflux have been found to have lower levels of beneficial bacteria, particularly Bifidobacterium, one of the first bacterial colonizers in a healthy newborn's gut. This imbalance, known as dysbiosis, may contribute to inflammation and digestive dysfunction.

Herbal Support

Research has also explored the use of gentle botanical combinations, including chamomile, lemon balm, and fennel, in supporting colicky infants. One study found an 85 percent reduction in crying in the group using this herbal combination compared to 49 percent in the placebo group. These are not fringe ideas. They are areas of genuine scientific inquiry.

Feeding Practices

Something as simple as the type of bottle used can make a meaningful difference. Anti-colic bottles designed to reduce air swallowing during feeding may help reduce the amount of trapped air that contributes to gas and discomfort. When a baby is already crying, they swallow additional air, which compounds the problem. Addressing feeding mechanics is a practical and often overlooked piece of the picture.

The Chiropractic Perspective: What Birth Has to Do With It

Many parents are surprised to learn that the birth process itself can be a contributing factor to colic and reflux. This is where chiropractic care, particularly pediatric chiropractic care, enters the conversation.

Birth Trauma and the Spine

The upper cervical spine, specifically the first and second vertebrae at the base of the skull, is the most vulnerable region of a newborn's spine during delivery. Prolonged labor, forceps or vacuum extraction, and cesarean births all place additional stress on this delicate area. When these vertebrae are even slightly misaligned, it places stress on the surrounding nervous system.

This kind of misalignment in a newborn does not always look dramatic. It may show up as difficulty latching, a preference for turning the head only one direction, persistent irritability, or colicky crying. These are the body's signals that the nervous system is under stress.

The Vagus Nerve Connection

The vagus nerve is one of the most important nerves in the body. It runs from the brainstem, through the neck, and down into the digestive organs. It is the primary communication highway between the brain and the gut. When the upper cervical spine is misaligned, it can place tension on the vagus nerve, disrupting the signals traveling between the brain and the stomach.

In practical terms, this means the stomach may receive incorrect information from the brain, contributing to poor gastric emptying, increased gas, and reflux symptoms. The vagus nerve is not a minor player in infant digestion. It is central to it.

What a Chiropractic Adjustment Looks Like for a Baby

The image many people have of chiropractic care involves cracking and forceful movements. Pediatric chiropractic care looks nothing like that. Adjustments for infants involve gentle fingertip pressure, often described as comparable to the pressure you would use to test whether a tomato is ripe. Many babies fall asleep during their adjustment. The goal is to gently restore proper alignment and reduce nervous system stress, not to manipulate the spine in any forceful way.

What the Research Shows

The research supporting chiropractic care for infant colic and reflux is growing steadily. A 2012 systematic review found that chiropractic adjustments reduce crying time in colicky infants. A randomized controlled trial found that babies receiving chiropractic care cried approximately one hour less per day on average. Research also indicates that nine out of ten infants with reflux symptoms experience significant improvement following chiropractic care. A large survey of nearly 22,000 parents found that 99.7 percent reported no adverse effects from their child's chiropractic care.

In a direct comparison between anti-gas medication and pediatric chiropractic care, 38 percent of babies using the medication showed improvement in crying, compared to 67 percent of those receiving chiropractic care. That is a meaningful difference.

A systematic review examining 26 studies concluded that chiropractic care is a viable, evidence-supported option for infantile colic, particularly given that conventional medical options have not consistently outperformed placebo and carry their own risk profiles.

What Parents Can Realistically Expect

Parents who bring their newborns in for evaluation and care often report noticeable changes within the first 24 to 72 hours. Latching may improve, colicky episodes may decrease in frequency and duration, and babies often begin sleeping for longer stretches. A more settled, comfortable demeanor tends to emerge as the nervous system is better supported.

It is important to approach this with realistic expectations. Every baby is different, and the timeline of improvement will vary. What the research and clinical experience consistently show, however, is that addressing the nervous system and the root causes of digestive dysfunction tends to produce better outcomes than symptom suppression alone.

Conclusion

Colic and reflux are among the most common and most distressing experiences in early parenthood. They are also among the most misunderstood. The conventional approach of managing symptoms with medication has real limitations, and growing numbers of parents and practitioners are recognizing the value of looking deeper.

Functional medicine asks why. Chiropractic care addresses the nervous system at its foundation. Together, these approaches offer families a more complete path forward, one that honors the complexity of a newborn's developing body and seeks to support it rather than simply suppress its signals.

If your baby is struggling, know that there are thoughtful, evidence-informed options worth exploring that won't just treat symptoms but the underlying issues to optimize your baby's health in the future. Your baby's body is communicating something. The goal is to listen carefully enough to understand what it is saying and we can help bring relief to your baby and relief to you, knowing that we treat the whole body and not just symptoms.
