Is MiraLAX Making Your Child's Behavior Worse?

March 13, 2026

And Does it Effect More Than Your Child’s Digestion?

Many parents are told that MiraLAX is a simple, safe solution for childhood constipation. A pediatrician writes the prescription, you follow the instructions, and you hope relief is right around the corner. But weeks later something feels different. Your child may begin having emotional meltdowns, anxiety, mood swings, or behaviors that seem completely out of character.


If you have noticed these changes and wondered whether they could be connected, you are not alone. More and more parents are asking deeper questions about medications that are commonly used for constipation. They are also realizing that there may be more to the story than they were originally told.


Understanding the Bigger Picture Behind MiraLAX

MiraLAX contains polyethylene glycol 3350, an osmotic laxative that works by pulling water into the intestines to soften stool. In adults, this mechanism can provide temporary relief for constipation.


However, many parents are surprised to learn that MiraLAX has not received FDA approval for use in children under the age of 17. Despite this, it is commonly prescribed “off label” for pediatric constipation.


Over the years, the FDA has received reports from parents describing possible neuropsychiatric symptoms in children using polyethylene glycol products. These reports include anxiety, aggression, obsessive behaviors, and mood changes. Research is still ongoing, but the concern has led many families to question whether long term reliance on laxatives truly addresses the underlying problem.


For parents who have experienced these behavioral changes in their children, the concern is not theoretical. It is deeply personal.


A Parent’s Experience: When Relief Did Not Feel Like Relief

Laura was doing exactly what any caring parent would do. Her son Justin had struggled with constipation since infancy, and when his pediatrician recommended MiraLAX, she trusted it was the right step.


Instead of improvement, she began noticing changes in his behavior. Justin became anxious, easily frustrated, and prone to emotional outbursts that seemed to appear without warning.


Laura later shared that she had never been told behavioral side effects were even a possibility. Like many parents, she began searching for answers when the treatment meant to help her son seemed to be creating new challenges.


Her story is not uncommon. According to the American Academy of Family Physicians, constipation affects up to 30 percent of children worldwide. Because of this prevalence, osmotic laxatives such as polyethylene glycol are frequently used as first line treatments.


But the question many families begin asking is simple. Are we addressing the root cause, or are we only managing symptoms?


Why Treating Symptoms Alone Often Falls Short

From a physiological standpoint, MiraLAX works by drawing water into the intestines through osmosis. This softens stool and can create bowel movements. While this may provide short term relief, it does not necessarily restore the body’s natural digestive regulation.


Healthy digestion relies heavily on the nervous system. The brain, spinal cord, and vagus nerve coordinate the movement of food through the digestive tract, regulate enzyme production, and signal when the body is ready for elimination.


When the nervous system is under stress or not communicating properly, the digestive system can slow down. Constipation is often one of the earliest signs that this communication is not functioning optimally.


Simply forcing movement through osmotic action does not correct the neurological signals that control digestion.


Potential Side Effects Parents Should Be Aware Of

Like any medication, osmotic laxatives can have side effects. Some of the more commonly reported digestive symptoms include bloating, abdominal discomfort, nausea, and diarrhea.


In some cases, prolonged use may contribute to electrolyte imbalances or dependence on laxatives for bowel movements.


Parents have also reported behavioral and mood related changes in some children. While research is still developing in this area, these reports highlight the importance of taking a broader view of digestive health.


Additionally, growing research continues to show how early life factors influence gut health. Studies have demonstrated that multiple courses of antibiotics during early childhood can significantly impact the gut microbiome, increasing the risk of allergies, asthma, and digestive disorders later in life.


All of this points to a central principle. Digestive health is closely tied to neurological regulation, immune balance, and overall physiological function.


The Question That Matters Most

Instead of asking only how to make a child have a bowel movement, a more important question is this: Why is the constipation happening in the first place?


Constipation rarely appears without a reason. It often reflects underlying stress within the nervous system that interferes with the body’s ability to coordinate digestion.


The Nervous System and the “Rest and Digest” Response

The autonomic nervous system controls two major states within the body. The sympathetic state is often called “fight or flight.” It prepares the body to deal with stress, danger, or perceived threats. The parasympathetic state is known as “rest and digest.” In this state the body can focus on digestion, healing, immune balance, and restoration.


When children experience ongoing stress on their nervous system, they may become stuck in a sympathetic dominant state. When this happens, digestion slows and constipation can develop. Several early life factors can contribute to this imbalance. Prenatal stress during pregnancy can influence how a developing nervous system responds to stress after birth. Birth interventions such as C section delivery, forceps, or vacuum extraction can place mechanical stress on the infant spine and nervous system. Environmental toxins, including pesticides, plastics, and heavy metals, may interfere with neurological regulation. Repeated antibiotic use can disrupt the gut microbiome, which plays a critical role in digestive function and immune balance.

When multiple stressors occur together, they can create what many clinicians refer to as a perfect storm for nervous system dysregulation.


A Neurologically Focused Approach to Digestive Health

At Living Water Chiropractic, we look beyond the symptom of constipation and focus on the neurological patterns that may be driving it.

Neurologically focused chiropractic care evaluates how well the nervous system is regulating the body. When spinal stress, known as subluxation, interferes with communication between the brain and body, digestive function can be affected.


Advanced technology known as INSiGHT Scans helps measure how the nervous system is functioning. These scans evaluate factors such as heart rate variability, thermal patterns along the spine, and muscle activity that may indicate neurological stress.

This information allows us to see how well the body is regulating stress and digestion.


Through gentle, precise chiropractic adjustments designed specifically for children, the goal is to reduce nervous system interference and restore healthy communication between the brain and body. When the nervous system shifts back toward a balanced “rest and digest” state, the body often begins to regulate digestion more naturally.


Real Change Happens When the Nervous System Is Supported

When Justin began neurologically focused care, his scans showed significant nervous system stress and imbalance.

Over the following weeks, as his nervous system regulation improved, his digestive function began to normalize. His stomach discomfort decreased and his bowel movements became more regular.


Laura also noticed that Justin’s behavior improved significantly as his nervous system became more balanced. Digestive improvements are often one of the first signs of nervous system restoration in children. Families frequently notice additional changes such as improved sleep, better emotional regulation, stronger immune function, and overall wellbeing.

What is Subluxation?

What Is Subluxation? Understanding the Missing Piece Behind ADHD, Autism, Anxiety, and Chronic Childhood Health Challenges If you’ve taken your child to specialist after specialist, tried therapy after therapy, changed diets, added supplements, and still feel like you’re missing something important — you are not alone. Many parents today are searching for answers to chronic childhood challenges like: ADHD Autism Anxiety Sensory Processing Disorder Sleep struggles Chronic ear infections Digestive issues Emotional dysregulation Immune challenges And despite all the appointments and interventions, many families still feel stuck. At Living Water Chiropractic, we believe one of the most overlooked pieces of the puzzle is the nervous system — specifically a condition called subluxation. Understanding subluxation may completely change the way you view your child’s health and healing. What Is Subluxation? Most people think subluxation simply means “a bone out of place.” But neurologically-focused chiropractic care looks much deeper than structure alone. Subluxation is a neurological stress condition that interferes with healthy communication between the brain and body. It typically involves three major components: 1. Misalignment Within the Neurospinal System Physical stress and tension can create shifts within the spine, especially in the upper neck and brainstem regions. 2. Restricted Motion and Joint Dysfunction When joints lose healthy movement, the nervous system loses important sensory input that helps regulate balance, coordination, posture, and body awareness. 3. Neurological Interference As the nervous system becomes stressed and dysregulated, the brain begins receiving distorted stress signals instead of calm, balanced communication from the body. In simple terms, subluxation disrupts the body’s ability to regulate and adapt appropriately. Why the Nervous System Matters So Much Your child’s nervous system controls and coordinates every major function in the body. That includes: Sleep Digestion Immune function Emotional regulation Focus and attention Sensory processing Motor development Behavior When the nervous system becomes overwhelmed and stuck in chronic stress mode, symptoms often begin appearing across multiple systems at once. This is why many children experience seemingly unrelated issues that continue evolving over time. For example: Colic may progress into chronic ear infections Ear infections may become sensory challenges Sensory dysregulation may later appear as ADHD or anxiety Digestive dysfunction may occur alongside behavioral struggles These are often not isolated conditions. They are signs of an overwhelmed nervous system. Understanding Proprioception and Stress Signals One of the most important concepts parents can understand is how the brain receives information from the body. Healthy joints and muscles constantly send calming, organizing signals to the brain through a process called proprioception. Proprioception helps the brain understand: Where the body is in space How to coordinate movement How much muscle tone is needed Whether the body feels safe and regulated But when spinal joints become restricted or stressed, those healthy signals decrease. At the same time, stress and threat signals increase. This leaves many children stuck in a chronic “fight or flight” state where the brain constantly perceives danger or overload — even when no true threat exists. This nervous system stress can contribute to: Meltdowns Anxiety Hyperactivity Sensory overload Sleep difficulties Emotional dysregulation Chronic tension Immune challenges What often looks behavioral on the outside may actually be neurological on the inside. Why the Brainstem and Upper Neck Are So Important The upper cervical spine and brainstem play a major role in nervous system regulation. This area helps control: Breathing Digestion Heart rate Immune responses Sensory filtering Motor coordination Stress adaptation The brainstem also works closely with the Vagus Nerve, one of the body’s most important calming and regulatory pathways. When stress, tension, or subluxation affects this region, children may struggle to properly regulate their nervous system responses. This is why nervous system dysfunction can look so different from child to child. Some children develop sensory challenges. Others struggle with immune dysfunction, emotional regulation, speech delays, sleep issues, focus problems, or motor coordination difficulties. Different symptoms can often trace back to the same neurological stress patterns. How Subluxation Develops: The “Perfect Storm” Most children do not develop chronic nervous system stress from a single event. Instead, we often see a buildup of stressors over time — what we call the Perfect Storm. Prenatal Stress High levels of stress during pregnancy can impact a baby’s developing nervous system long before birth. Stress hormones influence neurological development and may increase nervous system sensitivity early in life. Birth Stress and Birth Interventions Difficult or highly medicalized births can place significant tension on a newborn’s upper neck and nervous system. Common stressors include: Forceps delivery Vacuum extraction Induction Prolonged labor Emergency C-sections These interventions may affect the brainstem and vagus nerve regions that are critical for healthy regulation. Environmental and Immune Stress Today’s children are exposed to significantly higher levels of environmental stress than previous generations. Factors may include: Chronic inflammation Gut microbiome disruption Processed foods Toxin exposure Repeated antibiotics Immune system stress Over time, these stressors can overwhelm a child’s ability to adapt and regulate effectively. Signs of Nervous System Dysregulation in Children Every child expresses nervous system stress differently, but common signs may include: Physical Signs Colic Reflux Constipation Chronic ear infections Poor sleep Frequent illness Low or high muscle tone Toe-walking Coordination challenges Sensory and Behavioral Signs Sensory sensitivities Meltdowns Difficulty calming down Emotional dysregulation Hyperactivity Anxiety Sensory seeking behaviors Developmental Signs Speech delays Focus difficulties Motor delays Tics or stimming Challenges with social engagement These symptoms are often signs of a nervous system struggling to stay regulated under chronic stress. Why This Often Gets Missed Traditional healthcare often focuses on symptom management rather than nervous system regulation. Many providers are not trained to evaluate autonomic nervous system dysfunction, vagus nerve stress, or neurological subluxation patterns. As a result, families are frequently left managing symptoms without fully understanding the neurological stress underneath them. At Living Water Chiropractic, we take a different approach. How Neurologically Focused Chiropractic Care Helps We use advanced INSiGHT™ Scans to evaluate how your child’s nervous system is functioning. These scans help us assess: Stress patterns Dysautonomia Muscle tension Neurological imbalance Adaptability of the autonomic nervous system Rather than guessing, we use objective measurements to better understand what your child’s nervous system is experiencing. From there, gentle neurologically-focused chiropractic adjustments are designed to help restore healthy communication between the brain and body. The goal is to help your child shift out of chronic stress mode and into a more regulated state. Why Regulation Comes Before Progress One of the biggest breakthroughs families experience is realizing that nervous system regulation creates the foundation for healing. When the nervous system becomes more balanced, other therapies and interventions often begin working more effectively too. Parents commonly notice improvements in: Sleep Digestion Emotional regulation Focus Sensory processing Immune resilience Overall adaptability Healing is not usually random. When the nervous system becomes more regulated, the body often begins healing in a more organized and predictable sequence. There Is Hope for Your Child If this sounds familiar, please know this: Your child is not broken. Their symptoms are not random. And you are not failing as a parent. Many children struggling with ADHD, autism, anxiety, sensory challenges, chronic illness, or developmental delays are living with an overwhelmed nervous system that has never fully had the chance to regulate and heal. At Living Water Chiropractic, we help families uncover the neurological stress patterns that may be contributing to their child’s challenges and create a personalized path forward.
