If you're a new parent you're likely used to diapers perhaps, bottle feedings and the occasional spitting up.

Now, a new study, just published in the Journal of Pediatrics, looks at whether bottle-feeding may be linked to a serious condition called pyloric stenosis.

Pyloric stenosis is a blockage between the stomach and intestines, which can cause projectile vomiting, dehydration and constipation. It is one of the more common causes of intestinal obstruction during infancy, and often requires surgery to correct.

Researchers looked at data from more than 70-thousand Danish babies, 65 of them had to have surgery for pyloric stenosis and among those, 29 were bottle fed before diagnosis. The researchers determined that the bottle-fed babies had nearly 5-times higher risk for pyloric stenosis than those who were not bottle-fed at all.

The researchers say that while the connection is clear, the reason behind it is not. They suggest breastfeeding your baby exclusively in the first months of life.
