Which age population has a more alkaline gastric pH?

Neonates have a more alkaline gastric pH, which is an important physiological characteristic at this age. At birth, the gastric secretions in neonates are less acidic compared to those of older children and adults. This relatively high pH is attributed to the immature gastrointestinal system, which gradually develops more acidic gastric secretions as the infant grows.

The alkaline environment in neonates can affect the absorption and metabolism of medications, making it crucial for healthcare providers to consider when prescribing treatments. As children grow and their digestive systems mature, gastric pH typically becomes more acidic to aid in digestion and protect against pathogens.

This understanding underscores the significance of age in pharmacology and nutrition, as the age of a patient can profoundly influence gastric conditions and the subsequent effectiveness of medications.
