What are common risk factors for milk-protein induced enterocolitis?

Milk-protein induced enterocolitis, commonly affecting infants, is often associated with a range of allergic conditions, particularly those related to immunological responses. The correct answer highlights the connection between the condition and a family history of allergies, eczema, or asthma. These conditions are manifestations of atopy and can indicate a predisposition to allergic reactions.

In infants diagnosed with milk-protein induced enterocolitis, exposure to cow's milk protein can provoke an immune-mediated response, leading to gastrointestinal symptoms. Families with a history of allergic diseases suggest a genetic component that can increase the likelihood of developing allergies, including food allergies, which are critical in this context.

The other options do not relate to the immunological aspect of milk-protein induced enterocolitis. For instance, family histories involving obesity, diabetes, or hypertension are more closely associated with metabolic or chronic diseases rather than allergy profiles. Previous surgeries and cancer histories do not have a direct relevance to food allergies or enterocolitis. Contextually, it is crucial to recognize that milk-protein induced enterocolitis is primarily an allergic condition, and the family history of atopic diseases serves as a strong indicator of potential risk.
