I was wondering if anyone else on glow that has had a son with Pyloric Stenosis? I hate how unaware and uninformed I was about something so serious. Did anyone else have a similar experience? For something the doctors told me was "fairly common but life threatening" I knew very little about what was happening to my son and why he needed emergency surgery. Please share your story and help to make aware of the signs.

Pyloric stenosis (also called infantile hypertrophic pyloric stenosis) is a type of gastric outlet obstruction, which means a blockage from the stomach to the intestines.

Pyloric stenosis affects about 3 out of 1,000 babies in the United States. It's more likely to affect firstborn male infants and also runs in families. Most infants who have it develop symptoms 3 to 5 weeks after birth.

Symptoms of pyloric stenosis typically begin when a baby is around 3 weeks old. They include:

Vomiting. The first symptom is usually vomiting. At first it may seem that the baby is just spitting up often, but then it tends to become projectile vomiting, in which the breast milk or formula is ejected forcefully from the mouth, in an arc, sometimes over a distance of several feet. Projectile vomiting usually takes place soon after the end of a feeding, although in some cases it can happen hours later.

The vomited milk might smell curdled because it has mixed with stomach acid. The vomit will not contain bile, a greenish fluid from the liver that mixes with digested food after it leaves the stomach.

Despite vomiting, a baby with pyloric stenosis is usually hungry again soon after vomiting and will want to eat. It's important to know that even with the vomiting, the baby might not seem to be in great pain or at first look very ill.

Changes in stools. Babies with pyloric stenosis usually have fewer, smaller stools (poops) because little or no food is reaching the intestines. Constipation or poop with mucus also can happen.

Failure to gain weight or weight loss. Most babies with pyloric stenosis will fail to gain weight or will lose weight. As the condition gets worse, they might become dehydrated.

Dehydrated infants are less active than usual, and they may develop a sunken "soft spot" on their heads and sunken eyes, and their skin may look wrinkled. Because less pee is made, they can go more than 4 to 6 hours between wet diapers.

Waves of peristalsis. After feeds, increased stomach contractions may make noticeable ripples, which move from left to right over the baby's belly as the stomach tries to empty itself against the thickened pylorus.
