Projectile vomiting is the most frequent symptom in babies with pyloric stenosis, according to Children's Hospital of Wisconsin. The baby regurgitates significant amounts of formula or breast milk, often sending them several feet across the room. The baby often nurses eagerly and is very hungry before and after nursing.
In addition to the forceful vomiting, other symptoms of pyloric stenosis include a general malaise, a reduction in bowel movements, constipation, unexplained weight loss and stools that are composed of mucus. Doctors perform a physical examination that includes blood tests, abdominal ultrasound and X-ray as well as a barium swallow in advance of a series of images of the upper gastrointestinal tract, as stated by Children's Hospital of Wisconsin.
The treatment for pyloric stenosis is surgery to adjust the pyloric valve. The specific process depends on the gestational age, general health and medical history for the infant. The degree of the problem, the baby's tolerance for different medicines and procedures, and the parent's preferences all contribute to shape the doctor's plan. Before the surgery, the doctor may have to treat dehydration and imbalances in mineral levels. Intravenous fluids can replace minerals and water, and once the dehydration has been treated, it is safe to perform the surgery under anesthesia. The surgeon makes a small cut just over the navel and repairs the muscle, reports Children's Hospital of Wisconsin.
