Pyloric stenosis history and symptoms

The hallmark of infantile pyloric stenosis is progressively worsening vomiting within the first few weeks to months of life. A positive history of bottle feeding and cesarean section delivery is suggestive of infantile pyloric stenosis. The most common symptoms of infantile pyloric stenosis include vomiting, belching, persistent hunger. Less common symptoms of infantile pyloric stenosis include failure to gain weight or weight loss, jaundice, lethargy and decreased urine output. The hallmark of adult type pyloric stenosis is progressively worsening projectile vomiting. A positive history of chronic peptic ulcers and fibrosis near the gastric outlet is suggestive of adult type pyloric stenosis. The most common symptoms of adult type pyloric stenosis include vomiting with occasional relief after vomiting, belching, epigastric pain. Less common symptoms of adult type pyloric stenosis include failure to gain weight or weight loss and symptoms of dehydration like increased thirst, dry mouth and decreased urine output.
