Many parents come to us feeling confused and worried.
Your child may have been struggling with constipation, and your pediatrician recommended MiraLAX to help. At first, you hoped it would bring relief. But after a few weeks, you may have started noticing changes—meltdowns, anxiety, mood swings, or behaviors that seem out of character for your child.
If this sounds familiar, you’re not alone. Many families start asking questions when something just doesn’t feel right.
Let’s talk about what may be going on and why constipation in children is often more complex than it seems.
What Many Parents Aren’t Told About MiraLAX
MiraLAX (polyethylene glycol) is commonly recommended for constipation in children. However, many parents are surprised to learn that it is not FDA-approved for children under age 17, meaning its use in kids is considered “off-label.”
While many children take it without problems, some parents have reported behavioral and neurological symptoms after starting it, including:
• Increased anxiety
• Irritability or aggression
• Mood swings
• Obsessive or repetitive behaviors
These reports have led many families to start asking deeper questions about how constipation should really be addressed.
A Parent’s Story
One mom shared her experience with us after her son had struggled with constipation since infancy. When their pediatrician recommended MiraLAX, she trusted it would help.
But not long after starting it, she noticed changes in his behavior. He became more anxious and had emotional outbursts that felt very unlike him.
She told us,
“I had no idea MiraLAX could make his behavior even worse,” Laura shared. “My doctor definitely didn’t tell me that. He mentioned nothing about MiraLAX side effects.”
Laura’s experience isn’t rare. According to the American Academy of Family Physicians, constipation affects up to 30% of children worldwide, and many pediatricians turn to polyethylene glycol (the active ingredient in MiraLAX) as a first-line treatment. But the potential risks are often overlooked, leaving parents like Laura searching for answers when their child’s health deteriorates instead of improving.
Why Constipation Is Often Treated as Just a Symptom
Most conventional treatments focus on helping the body pass stool more easily. MiraLAX works by drawing water into the intestines to soften stool so it moves through more easily.
For some children this can provide temporary relief. However, it doesn’t address why the constipation started in the first place.
Constipation is often a signal that the digestive system isn’t functioning as smoothly as it should.
And digestion is controlled by something very important:
The nervous system.
The Nervous System’s Role in Digestion
Your child’s nervous system acts like the body’s communication network. It coordinates digestion from beginning to end—telling the stomach, intestines, and colon when and how to move.
When the nervous system is under stress or not functioning optimally, digestion can slow down. One of the most common signs of this imbalance in kids is constipation.
Here’s what creates that disruption, what we call “The Perfect Storm“:
• Stress during pregnancy
• Birth interventions such as C-sections, forceps, or vacuum delivery
• Early antibiotic use
• Environmental stressors
• Physical tension within the spine and nervous system
These factors combine to create what we call sympathetic dominance. Your child’s nervous system is stuck in “fight or flight” mode, like a computer with too many tabs open. It simply can’t coordinate basic digestive functions properly.
Looking at the Root Cause
At Foundation of Stone Pediatric & Perinatal Family Chiropractic, we focus on understanding how a child’s nervous system is functioning.
We use INSiGHT scans to gently and safely assess how the nervous system is working. These scans measure:
• Heart Rate Variability (HRV) to evaluate stress patterns
• Thermal scans to detect nervous system imbalance
• Surface EMG to assess muscle tension along the spine
These scans help us see whether the nervous system is stuck in a stressed state that could be affecting digestion and other functions.
From there, gentle chiropractic adjustments help reduce tension in the nervous system so the body can shift back into “rest and digest” mode.
What Parents Often Notice
When nervous system balance improves, digestion is often one of the first things to change.
Parents frequently report improvements such as:
• More regular bowel movements
• Less stomach discomfort
• Better sleep
• Calmer behavior
• Improved focus and emotional regulation
Every child is different, but when the nervous system functions better, the body can begin doing what it was designed to do.
