Complications
By Mayo Clinic staffPyloric stenosis can lead to:
- Failure to grow and develop at a normal, healthy rate.
- Dehydration from frequent vomiting, One effect of dehydration is an electrolyte imbalance. Electrolytes are minerals, such as chloride and potassium, that circulate in the body's fluids to help regulate many vital functions. When a baby loses more fluid from vomiting than he or she takes in from eating, an imbalance of electrolytes eventually occurs.
- Stomach irritation. Repeated vomiting can irritate your baby's stomach. This irritation may even cause mild bleeding.
- Jaundice. Rarely, infants who have pyloric stenosis develop a yellowish discoloration of the skin and eyes (jaundice) caused by a buildup of a substance secreted by the liver called bilirubin.
