Pyloric stenosis typically begins between which ages?

Explanation:
Pyloric stenosis in infants generally shows up after the newborn period, during the first weeks of life. The hypertrophy of the pyloric muscle develops over time, so symptoms usually appear around 2 to 6 weeks of age, with the classic teaching window around 2 to 4 weeks. That’s why the option describing 2 to 4 weeks is the best match. Presents earlier (2–4 days) is too soon for the obstruction to develop, and waiting until 2–4 months or 6–8 weeks passes the typical window, though rare presentations beyond the early weeks can occur.
