Pyloric stenosis is a condition that occurs in infants and causes narrowing or blockage of the passage between the stomach and the small intestine. It affects approximately 3 in 1,000 babies and is more common in males than females. The condition typically presents itself between 2-6 weeks of age and is characterized by vomiting, weight loss, and dehydration.

The cause of pyloric stenosis is unknown, but it is believed to be a combination of genetic and environmental factors. Research has shown that there is an increased risk of pyloric stenosis in babies with a family history of the condition. Additionally, certain medications taken during pregnancy, such as antibiotics or antidepressants, may increase the risk of developing pyloric stenosis.

The most common symptom of pyloric stenosis is projectile vomiting, which occurs shortly after feeding. The vomiting may be forceful and may continue until the stomach is completely empty. This can lead to dehydration, electrolyte imbalances, and weight loss. In addition to vomiting, other symptoms of pyloric stenosis include:

– Delayed or poor weight gain
– Fewer wet diapers than usual
– Constant hunger
– Palpable knot or lump in the upper abdomen
– Irritability or fussiness after feeding

If your baby is exhibiting these symptoms, it is important to contact your healthcare provider immediately. Diagnosis of pyloric stenosis involves a physical exam, imaging tests such as an ultrasound, and blood tests to assess for dehydration and electrolyte imbalances.

Treatment for pyloric stenosis involves surgery to remove the obstruction in the pylorus. The surgery, known as a pyloromyotomy, involves making a small incision in the infant’s abdomen and cutting the muscle fibers of the pylorus to widen the passage between the stomach and small intestine. This surgery is highly effective and has a success rate of over 95%.

After surgery, infants are typically able to resume feeding within a few hours and often exhibit significant improvement in their symptoms within 24-48 hours. It is important to closely monitor your baby after surgery for signs of infection, bleeding, or other complications.

While pyloric stenosis can be a scary diagnosis, it is important to remember that with prompt diagnosis and treatment, most babies make a full recovery. Early recognition of symptoms is key to successful treatment, so it’s important to be aware of the signs and symptoms of this condition. If you suspect your baby may have pyloric stenosis, contact your healthcare provider right away.
