What sign is associated with Kwashiorkor?

The "Flag sign" is indeed associated with Kwashiorkor, which is a form of severe malnutrition primarily seen in children due to protein deficiency. The flag sign refers to the alternating bands of discoloration in the hair, typically seen in children with this condition. These bands reflect periods of malnutrition and are indicative of underlying protein deficiency affecting hair growth and health.

Kwashiorkor primarily results from inadequate protein intake despite adequate calorie consumption, leading to various clinical features, including edema, growth retardation, and changes in hair texture and appearance. The flag sign specifically highlights the impact of nutrient deficiencies on hair health and is a visible manifestation of the underlying condition.

While pitting edema, dry skin, and brittle nails can be related to malnutrition, the flag sign is uniquely characteristic of Kwashiorkor and serves as a specific diagnostic indicator of this condition.
