Pyloric Stenosis: Causes, Symptoms, Diagnosis & Treatment

by admin

What is Pyloric Stenosis?

Stomach problems can be caused by a disease called pyloric stenosis. The pylorus, the tube connecting the lower stomach to the small intestine, becomes abnormally thin. Because of this constriction, food may have trouble leaving the stomach and entering the intestines.

This condition usually develops in infants within their first few weeks of life. It occurs more commonly in males than females and does not appear to be linked with any particular ethnicity or family history.

While the root cause of Pyloric Stenosis remains a mystery, some research points to a possible genetic component. Antibiotic use during pregnancy or infancy has also been connected to this illness.

Poor weight gain, dehydration, persistent hunger, and low energy levels are all signs of Pyloric Stenosis, as can vomiting after eating, especially if it becomes strong. Untreated Pyloric Stenosis can cause more issues, including electrolyte imbalances and dehydration, so it’s important to get medical help right away if you observe your newborn exhibiting these symptoms.

Pyloric Stenosis may sound scary for new parents but understanding its causes and symptoms will help you recognize when your baby needs medical assistance quickly.

Causes of Pyloric Stenosis

Infants as young as two to eight weeks of age are at risk for developing pyloric stenosis. The pylorus, the tube connecting the stomach and the small intestine, can get blocked if the muscles around it become thickened or enlarged. This constriction can prevent food from moving from the stomach to the intestines.

Although the root cause of pyloric stenosis is still unknown, it does seem to be inherited. A higher chance of acquiring this illness has also been linked to the use of certain drugs during pregnancy.

Other possible causes include abnormal nerve supply leading to overgrowth of muscle cells or exposure to chemicals that disrupt normal growth and development. Some studies have also suggested that bottle-fed babies may be more likely than breastfed ones to develop pyloric stenosis.

While there are still many unknowns about what leads someone down this path towards having a narrowed passageway at their stomach’s outlet valve – research suggests some factors could play into why some people develop symptoms while others don’t

Symptoms of Pyloric Stenosis

Pyloric stenosis is a disorder that affects the digestive system, specifically the opening between the stomach and small intestine. It is more common in infants under 6 months old, but can also occur in adults.

The main symptom of pyloric stenosis is vomiting after feeding. The vomit may be forceful and project several feet away from the baby or adult. The vomit may contain partially digested food or bile.

Other symptoms include dehydration due to fluid loss from frequent vomiting, weight loss, constipation, and lethargy. In severe cases, malnutrition and electrolyte imbalances can occur if left untreated.

If you or your child exhibits any of these signs, it is crucial that you get medical help immediately. To diagnose pyloric stenosis, a doctor will undertake a physical exam to look for an enlarged pylorus and may prescribe imaging tests like an ultrasound.

Early treatment can prevent complications associated with this condition including dehydration and malnourishment. Treatment options usually involve surgery to widen the narrowed opening between the stomach and small intestine allowing food to pass through normally again.

Diagnosing Pyloric Stenosis

Diagnosing Pyloric Stenosis can be done through various methods.

  • Diagnosis begins with a physical examination by a medical professional. An enlarged pylorus might cause an olive-shaped mass to be felt by the doctor in the stomach.
  • Ultrasound, X-ray, and blood tests can all be used to diagnose Pyloric Stenosis. An enlarged pylorus or a thickening muscular wall can be detected by an ultrasound, which uses sound waves to create images of the interior of the body. Pyloric stenosis, or intestinal narrowing, can be detected by an X-ray.
  • Blood tests are also conducted to check for dehydration and electrolyte imbalances caused by vomiting. These tests are crucial as they determine whether a patient needs hospitalization or not.

A diagnosis of Pyloric Stenosis requires prompt medical attention since it’s a serious condition that could lead to severe complications if left untreated. Therefore, parents must seek medical advice immediately on noticing symptoms such as projectile vomiting or weight loss in their infants.

Early detection through proper diagnosis techniques is critical in managing Pyloric Stenosis effectively.

Treatment for Pyloric Stenosis

In most cases, a surgical procedure called a pyloromyotomy is required to treat pyloric stenosis. The pylorus is unblocked by making a small incision in the baby’s abdomen and severing the muscle fibers around it.

Your child’s doctor may advise giving intravenous fluids to address any dehydration or electrolyte imbalances brought on by vomiting prior to surgery. Your infant will need to stay in the hospital for a few days after surgery for recovery and monitoring.

During recovery, your baby may experience some discomfort from the incision site and have trouble feeding initially. Your doctor may recommend smaller, more frequent feedings until your baby has fully recovered.

If you want to recuperate properly and avoid difficulties, you must strictly adhere to your doctor’s post-operative recommendations. Medication and endoscopic methods may be considered as alternatives to surgery in extremely unusual circumstances.

Prevention of Pyloric Stenosis

As the actual origin of pyloric stenosis remains unknown, it is not always viable to prevent this problem. But there are things parents may do to lessen their child’s risk of acquiring pyloric stenosis.

The use of erythromycin during pregnancy and in neonates should be avoided unless medically essential. The use of this antibiotic has been linked to an increased incidence of pyloric stenosis, according to the results of several studies.

Feeding your infant several small meals throughout the day is preferable to fewer, larger ones because it reduces the risk of pyloric stenosis. Evidence suggests that this reduces the likelihood of having this disease.

Be on the lookout for signs like newborn weight loss and projectile vomiting. Seek immediate medical attention if you experience any symptoms of concern.

Overall, avoiding certain drugs and altering feeding patterns might help lower the chance of pyloric stenosis developing in infants, while it may not always be possible due to its unknown origins.


Infant pyloric stenosis is quite prevalent in the first few months of life. Symptoms include violent vomiting and dehydration, brought on by a constriction of the passageway connecting the stomach and the small intestine.

Fortunately, pyloric stenosis can be easily diagnosed through physical examination and medical tests. Treatment options include surgery or medication, which are both highly effective in resolving this condition.

Parents should take measures to ensure their infant gets immediate medical attention if they detect symptoms of pyloric stenosis, but there is currently no proven technique to avoid pyloric stenosis in infants.

With proper diagnosis and treatment, most babies recover fully from pyloric stenosis without any long-term complications. As always, it’s important for parents to stay informed about their child’s health and seek medical advice whenever necessary.
