Pyloric stenosis is a condition that can occur in adults, just as it does in infants. While the symptoms in adults may sometimes differ, they generally share similarities. The main symptoms of pyloric stenosis in adults include:

1. Changes in Bowel Movements: One of the most prominent symptoms is a decrease in bowel motility. Less frequent or irregular bowel movements than normal may indicate pyloric stenosis.
2. Vomiting: Vomiting that occurs shortly after eating is another common symptom observed in adults.
3. Dehydration (Fluid Loss): Due to recurrent vomiting, the body experiences fluid loss, which can lead to a constant feeling of thirst.

If other symptoms are present in addition to the main ones listed above, the possibility of pyloric stenosis should be considered. Should such symptoms be noticed, it is important to consult a healthcare professional as soon as possible for proper diagnosis and treatment.
