🚽 What Poop Has to Do With Picky Eating: How Constipation Impacts Feeding (and What You Can Do!)
By the Feeding Experts at Expansion Speech Therapy LLC
Let’s talk about something that everyone does—but no one likes to talk about: poop.
You might not expect your child’s bowel habits to come up at a feeding therapy appointment, but trust us—it matters a lot. At Expansion Speech Therapy, we often see kids who struggle with eating also struggle with constipation. And research backs up what we see every day: what’s happening in the gut affects what happens at the table.
So what’s the connection?
🍽️ How Constipation Impacts Oral Feeding
Constipation isn’t just an issue in the bathroom—it can seriously affect your child’s appetite, comfort, and even their ability to chew and swallow. Here’s how:
1. Constipation Reduces Appetite
When the belly is full of stool, there’s less room for food. Children who are constipated may say they’re “not hungry” or push food away because their body is already uncomfortable.
🔬 Research shows that children with functional constipation often have decreased appetite and mealtime refusal (Velasco-Benítez & Medrano, 2018).
2. Abdominal Discomfort Makes Sitting for Meals Hard
Bloating, cramping, and pressure can make it hard to sit still—let alone enjoy a meal. This discomfort can lead to increased mealtime stress and behaviors that look like picky eating.
3. It Can Affect Motor Coordination
Believe it or not, being backed up can affect core stability, which is essential for safe swallowing and coordinated chewing. If your child’s trunk isn’t stable, their mouth may not work efficiently.
🧠 The enteric nervous system (gut-brain axis) influences motor planning and behavior—yes, even oral motor function (Mayer et al., 2015)!
4. Leads to Negative Associations with Eating
If your child feels worse after eating due to constipation, they may start linking food with discomfort, which creates long-term feeding aversions.
🚼 Signs Your Child Might Be Constipated
- Less than 3 bowel movements per week
- Hard, dry, or pellet-like stools
- Belly bloating or visible distention
- Frequent “accidents” after being potty trained
- Withholding behaviors (squeezing legs together, avoiding sitting)
- Irritability, poor sleep, or frequent refusal to eat
💡 Tips to Help Reduce Constipation (Backed by Science!)
Good news: there’s a lot you can do to help your child poop more regularly—and in turn, improve feeding!
1. Increase Fiber Intake
Fiber helps keep things moving! Aim for:
- Fruits like pears, apples (with skin), berries, and prunes
- Veggies like peas, broccoli, and sweet potatoes
- Whole grains (oatmeal, brown rice, quinoa)
🧪 Fiber is proven to improve stool frequency in children (Tabbers et al., 2014)
2. Stay Hydrated
Water helps fiber do its job. Offer water between meals and encourage frequent sipping throughout the day.
3. Establish a Toilet Routine
Have your child sit on the toilet for 5 minutes after meals—even if they don’t feel the urge. This uses the natural “gastrocolic reflex” that stimulates the bowels.
👩⚕️ This practice is supported by evidence-based toilet training protocols from pediatric GI literature (Borowitz et al., 2013).
4. Encourage Movement
Physical activity supports digestion. Playful movement like dancing, jumping, crawling, or yoga can help stimulate the gut.
5. Consult a Medical Professional
If constipation persists, speak with your pediatrician. Sometimes children may need medication like polyethylene glycol (Miralax), which is safe and effective in many cases when guided by a doctor.
🧠 Why This Matters in Feeding Therapy
At Expansion Speech Therapy, we look at the whole child—because feeding challenges are rarely “just” about eating. If your child is constipated, they may not benefit from feeding therapy until we address the discomfort in their gut. That’s why we ask about poop, posture, and everything in between.
We collaborate with pediatricians, GI specialists, dietitians, and families to create a plan that supports happy tummies and happier mealtimes.
