Pyloric Stenosis Specialists in Electronic City, Bengaluru, Karnataka

What is Pyloric Stenosis?

Pyloric stenosis is a condition affecting young infants in which the muscle at the outlet of the stomach, called the pylorus, becomes progressively thickened and enlarged, narrowing the passage through which food moves from the stomach into the small intestine. This progressive narrowing typically develops over the first few weeks of life and leads to forceful vomiting after feeding as the stomach struggles to empty against the obstruction. It is one of the most common conditions requiring surgery in infancy, and prompt diagnosis and correction of the resulting dehydration and electrolyte imbalance are important before surgical repair.

Causes of Pyloric Stenosis

The exact cause is not fully understood, but it is believed to result from a combination of genetic and environmental factors that lead to progressive thickening of the pyloric muscle over the first weeks of life. Risk factors include being a firstborn male child, a family history of pyloric stenosis, and exposure to certain antibiotics in early infancy. It typically develops after birth rather than being present at delivery, distinguishing it from a purely congenital malformation.

Symptoms of Pyloric Stenosis

Forceful, projectile vomiting shortly after feeding, persistent hunger and eagerness to feed again soon after vomiting, weight loss or poor weight gain, dehydration signs such as fewer wet diapers, visible wave-like stomach contractions after feeding, a palpable small, olive-shaped mass in the upper abdomen, irritability

Treatment & Types of Pyloric Stenosis in Electronic City, Bengaluru, Karnataka

Before surgery, correcting dehydration and electrolyte imbalances with intravenous fluids is essential, as this significantly reduces surgical risk. The definitive treatment is a surgical procedure called pyloromyotomy, in which the surgeon carefully cuts through the thickened pyloric muscle to widen the passage while leaving the inner lining intact, and infants typically resume normal feeding within a day or two after surgery with excellent long-term outcomes.
