Is MiraLAX Making Your Child’s Behavior Worse?

Many parents come into our office with a similar story.

Their child has been struggling with constipation. Their pediatrician recommends MiraLAX and reassures them that it is commonly used and safe. They begin using it hoping it will finally bring relief for their child.

But weeks later, something else begins to change.

Parents start noticing emotional meltdowns, increased anxiety, mood swings, or behaviors that feel completely out of character for their child. The connection can feel confusing and concerning, especially when no one mentioned this as a possibility.

If this sounds familiar, please know two things.
You are not alone, and your concerns deserve to be taken seriously.

For many families, this is the moment they begin asking deeper questions about what may really be going on inside their child’s body.

What Many Parents Are Never Told About MiraLAX

One of the most surprising things parents learn is that MiraLAX has never received FDA approval for use in children under the age of 17.

This does not mean it is never used in pediatric care. Doctors can prescribe medications “off label,” which means the medication is used outside of the specific population it was originally approved for. However, many parents are never told this distinction when the medication is recommended.

Over the years, the FDA has also received reports from families describing neuropsychiatric symptoms in children taking polyethylene glycol, the active ingredient in MiraLAX. Some parents have reported behavioral changes such as anxiety, aggression, mood shifts, or obsessive behaviors.

While research is still ongoing and the full picture is not completely understood, many families wish they had been given more information before starting the medication.

A Story We Hear More Often Than You Might Think

One mother, Laura, shared her experience after her son Justin was prescribed MiraLAX for chronic constipation.

Justin had struggled with digestive issues since he was very young, and when their pediatrician recommended MiraLAX, Laura trusted it would help his body finally regulate.

Instead, she began noticing changes in his mood and behavior that felt unfamiliar. Justin started experiencing anxiety, emotional outbursts, and aggression that seemed to appear suddenly.

Laura later shared that she had no idea behavioral changes could even be a possibility.

Stories like Laura’s are part of what has led many parents to begin asking a different question.

Instead of simply asking how to relieve constipation, they start asking why their child’s body is struggling in the first place.

Why Constipation Is Often More Than a Digestive Issue

In conventional care, constipation is usually treated as a digestive problem that needs to be managed.

The most common approach is to soften the stool or stimulate bowel movements through medication. While this may temporarily relieve the symptom, it does not always address why the digestive system became sluggish in the first place.

From a neurologically focused perspective, digestion is actually controlled by the nervous system.

Your child’s brain and spinal cord coordinate every step of digestion including:

• Stomach acid production
• Movement of food through the intestines
• Muscle contractions that create bowel movements
• Communication between the gut and brain

When the nervous system is functioning well, digestion flows naturally.

When that communication becomes disrupted, digestive challenges like constipation can begin to appear.

The Role of the Nervous System

The digestive system is largely controlled by the parasympathetic nervous system, often referred to as “rest and digest.”

When a child’s nervous system becomes stuck in a sympathetic stress state, also known as fight or flight, digestion often slows down.

This is one of the reasons constipation is so commonly seen in children whose nervous systems are under stress.

At Inspire Life Chiropractic, we often refer to the accumulation of stress on a child’s developing nervous system as The Perfect Storm.

The Perfect Storm That Can Impact Digestion

Many factors can influence how a child’s nervous system develops and functions.

Some of the most common contributors we see include:

Prenatal stress
Stress during pregnancy can influence how a baby’s nervous system develops and regulates stress responses after birth.

Birth interventions or birth stress
C sections, forceps deliveries, vacuum extraction, and long labor can place physical stress on a newborn’s spine and nervous system.

Early childhood stressors
Illness, antibiotics, inflammation, and environmental toxins can all influence nervous system balance during critical developmental periods.

Over time, these stressors can contribute to a nervous system that stays in a heightened stress response rather than shifting into the calm, restorative state needed for healthy digestion.

Why Simply Forcing a Bowel Movement May Not Solve the Problem

MiraLAX works through a process called osmosis.

It draws water into the intestines to soften the stool, helping it move through the digestive tract.

While this can help create a bowel movement, it does not necessarily restore the nervous system signals that control digestion in the first place.

For some children, this means the underlying cause of constipation remains unchanged.

Parents may notice that the medication becomes something their child depends on rather than a temporary solution.

Looking at the Root Cause

At Inspire Life Chiropractic, our focus is always on helping the nervous system function the way it was designed to.

Through Neurologically Focused Chiropractic Care, we look for areas of subluxation in the spine that may be interfering with the communication between the brain and body.

To better understand what is happening inside your child’s nervous system, we utilize INSiGHT Scans, which measure several important indicators of nervous system function.

These scans assess:

• Heart Rate Variability, which reflects stress and adaptability in the nervous system
• Thermal patterns that may indicate inflammation or imbalance
• Surface EMG readings that show areas of tension along the spine

This allows us to see where a child’s nervous system may be struggling and develop a personalized care plan.

Gentle chiropractic adjustments are then used to reduce stress on the nervous system and support the body’s natural ability to return to balance.

What Families Often Notice

When the nervous system begins functioning more efficiently, many families report improvements not only in digestion but in other areas of their child’s health as well.

Parents frequently notice changes such as:

• More regular and comfortable bowel movements
• Improved sleep
• Better emotional regulation
• Stronger immune resilience
• Greater overall calm and adaptability

Digestive motility is often one of the first areas to improve when the nervous system shifts back into a healthier balance.

Trusting Your Parental Instinct

If your child has been struggling with constipation or behavioral changes and something does not feel right, trust that instinct.

As parents, you know your child better than anyone.

Sometimes the answers are not about adding another medication, but about stepping back and asking a deeper question about what your child’s body may be trying to communicate.

Discover What’s Really Going On

At Inspire Life Chiropractic, we believe every child deserves the opportunity to grow and develop with a nervous system that is functioning at its highest potential.

If you would like to better understand what may be contributing to your child’s digestive challenges, we invite you to schedule a consultation and INSiGHT scan.

If you are not local to our office, you can also search the PX Docs directory to find a neurologically focused pediatric chiropractor near you.

Your child’s body is incredibly intelligent and capable of healing when given the right support.

And sometimes the first step is simply understanding what the nervous system has been trying to tell us all along.
