Hirschsprung Disease Signs in Babies
Content reviewed against published NIH, Mayo Clinic guidelines
Last reviewed:
If your baby has been diagnosed with or you suspect hirschsprung disease signs in babies, here is what the evidence says.
The short answer
Hirschsprung disease is a condition present at birth where nerve cells are missing from part of the large intestine, making it difficult or impossible to pass stool. It affects about 1 in 5,000 newborns and is usually diagnosed in the first few days or months of life. With surgery, most children go on to live full, healthy lives.
Key takeaways
- Hirschsprung disease is a condition present at birth where nerve cells are missing from part of the large intestine, making it difficult or impossible to pass stool.

- Usually normal when: Your newborn passed meconium within 48 hours and has regular bowel movements
- Call your doctor if: Your baby has a distended abdomen with green or bile-stained vomiting and fever, which could indicate enterocolitis — a life-threatening complication
- Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
Thousands of parents search for this exact thing. You are not alone.
By Age
What to expect by age
0-3 months
Most cases of Hirschsprung disease are detected in the newborn period. The key warning sign is failure to pass meconium (first stool) within 48 hours of birth. Newborns may also develop a swollen abdomen, vomiting (sometimes green or bile-stained), and reluctance to feed. If your newborn has not passed stool within the first two days, this needs prompt medical evaluation.
3-6 months
In milder cases, Hirschsprung disease may not be caught right away. Babies in this age range may show chronic constipation that does not respond to typical remedies, a persistently bloated belly, poor weight gain, and foul-smelling watery stools. If your baby has struggled with severe constipation since birth, discuss Hirschsprung disease with your pediatrician.
6-12 months
Older infants with undiagnosed Hirschsprung disease typically have a history of chronic, severe constipation since birth, failure to thrive, and abdominal distension. They may also develop enterocolitis, a dangerous intestinal infection. Diagnosis at this stage is less common but does occur, especially in short-segment disease.
12 months+
Very short-segment Hirschsprung disease can occasionally go undiagnosed into toddlerhood. Children may have lifelong severe constipation, slow growth, and a visibly swollen belly. If your toddler has had refractory constipation since infancy with no improvement despite treatment, ask your doctor about further evaluation.
What Should You Do?
When to take action
- Your newborn passed meconium within 48 hours and has regular bowel movements
- Your baby has occasional constipation that responds to dietary changes or gentle measures
- Your baby is gaining weight well and has a soft, non-distended abdomen
- Constipation started after starting solids rather than being present since birth
- Your newborn did not pass meconium within the first 48 hours of life
- Your baby has had severe, persistent constipation since birth that doesn't respond to standard treatment
- Your baby has a chronically swollen or hard abdomen with poor weight gain
- Your baby has a distended abdomen with green or bile-stained vomiting and fever, which could indicate enterocolitis — a life-threatening complication
- Your newborn has not had a bowel movement since birth and appears in distress

Bottom line
Most cases of hirschsprung disease signs in babies are normal. Talk to your pediatrician if your baby has a distended abdomen with green or bile-stained vomiting and fever, which could indicate enterocolitis — a life-threatening complication.
Trust your instincts. If something feels wrong, reach out to your pediatrician. Worrying about your baby means you care — that is a good thing.

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
Adrenoleukodystrophy (ALD) in Babies
X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.
How to Advocate for Your Child's Needs
You know your child better than anyone, and your observations matter. If you feel something is not right with your child's development or health, you have every right to ask questions, request evaluations, and seek second opinions. Advocating for your child is not being difficult - it is being a good parent.
Agenesis of the Corpus Callosum (ACC)
Agenesis of the corpus callosum (ACC) is a condition in which the corpus callosum — the bundle of nerve fibers connecting the left and right hemispheres of the brain — fails to develop partially or completely. It occurs in approximately 1 in 4,000 births and is one of the most common brain malformations. ACC can be detected on prenatal ultrasound or postnatal MRI. Outcomes vary enormously: some individuals with isolated ACC have normal intelligence and minimal difficulties, while others (especially when ACC occurs alongside other brain abnormalities or genetic syndromes) may have significant developmental delays. The variability means that prenatal counseling and postnatal monitoring are both essential.
