Final answer:
The basic patient demographic for pyloric stenosis is primarily infants, especially males, first-born children, and those with a family history of the condition. Risk may also increase with prematurity and certain environmental factors.
Step-by-step explanation:
The basic patient demographic for pyloric stenosis typically includes infants, particularly newborns within the first few weeks to months of life. The condition is more common in males than females, with a male-to-female ratio of about 4:1. Additionally, it is seen more frequently in first-born children. Certain genetic factors may contribute to the condition, as it tends to run in families. Prematurity and certain environmental factors such as exposure to antibiotics or bottle feeding may also increase the risk of developing pyloric stenosis.
It is important for health professionals to be aware of these demographics when diagnosing and treating pyloric stenosis, as early intervention is critical for preventing complications such as severe dehydration and weight loss due to the vomiting that characterizes the condition.
