This document discusses approaches to diagnosing and treating hypertension in children. It defines hypertension and outlines stages of severity. In infants and young children, hypertension is usually secondary to an underlying condition, while adolescents can develop primary or essential hypertension. Evaluation involves measuring blood pressure properly, considering causes of secondary hypertension, assessing for target organ damage like left ventricular hypertrophy, and determining if hypertension is primary or secondary. Treatment involves lifestyle changes, weight management if overweight, and potentially medications to lower blood pressure below guidelines.
