Pyloric Stenosis

Pyloric stenosis is a condition that affects the opening between the stomach and the small intestine called the pylorus. In this condition, the muscles of the pylorus become thickened, causing a narrowing or blockage of the pyloric channel. This leads to difficulties in food passing from the stomach to the intestines.

Pyloric Stenosis | Definition, Signs, Symptoms, Treatment

Common symptoms of pyloric stenosis include persistent vomiting, which may occur shortly after feeding, a palpable mass in the abdomen, and dehydration. Infants affected by this condition often experience weight loss and fail to thrive.

Although the exact cause of pyloric stenosis is unknown, it is believed to be influenced by both genetic and environmental factors. It is more commonly observed in males and is often diagnosed within the first few weeks or months of life.

Many of the drugs are primarily used for the treatment of different medical conditions. For example, zovirax is an antiviral medication used to treat herpes infections, while daklinza is mainly prescribed for chronic hepatitis C. Addyi is a medication used to treat hypoactive sexual desire disorder in premenopausal women. Synthroid is a synthetic thyroid hormone used to treat hypothyroidism, and cipro is an antibiotic used to treat bacterial infections. Other drugs listed are used for fertility treatment (clomid), hair loss (propecia and proscar), and erectile dysfunction (eriacta, suhagra, nizagara, silagra, kamagra, tadacip, caverta). Nolvadex is used for breast cancer treatment, while xyzal is an antihistamine used to relieve allergy symptoms.

Treatment for pyloric stenosis typically involves surgery to widen the pyloric channel. The most common surgical procedure for this condition is called pyloromyotomy, where the thickened muscles are divided to improve the passage of food. Following surgery, infants usually recover well and can resume normal feeding patterns.

  • Pyloric Stenosis:
    • Vomiting after feeding
    • Forceful projectile vomiting
    • Weight loss or poor weight gain
    • Constant hunger
    • Irritability or fussiness after eating
    • Dehydration
    • Decreased urine output
    • Visible waves of movement from left to right in the upper abdomen (peristalsis)
    • Palpable olive-shaped mass in the upper abdomen

Pyloric Stenosis

The causes of Pyloric Stenosis may include:

  • Genetic factors
  • Inherited susceptibility
  • Abnormal muscle development in the pylorus
  • Overgrowth of the pyloric muscle
  • Local inflammation or infection

Pyloric Stenosis Diagnosis

Information about Pyloric Stenosis:

Pyloric Stenosis is a condition characterized by an abnormally thickened muscle at the outlet of the stomach, known as the pylorus. It primarily affects infants and causes blockage or narrowing of the passage between the stomach and the small intestine. Common symptoms include forceful vomiting, dehydration, weight loss, and infrequent bowel movements.

Methods for Diagnosing Pyloric Stenosis:

  • Physical Examination: A doctor will carefully examine the abdomen for signs of an enlarged pylorus or an olive-shaped mass, which may be palpable.
  • Medical History Assessment: The doctor will obtain a detailed medical history, including information about the infant's feeding patterns, vomiting frequency, and weight loss. This helps in ruling out other potential causes for the symptoms.
  • Ultrasound: An abdominal ultrasound is commonly used to confirm the diagnosis of pyloric stenosis. It allows visualization of the thickened pylorus muscle and helps in measuring its length and width.
  • Lab Tests: Blood tests may be performed to assess electrolyte levels and ensure the baby is not dehydrated.

It is important to note that this is just an example markup. The actual diagnosis and methods may vary depending on the individual case and the medical professional's judgment.
