What is a common physical manifestation of Kwashiorkor?

Kwashiorkor is a form of protein-energy malnutrition that typically occurs in children who have an inadequate intake of protein despite sufficient caloric intake. One of the distinctive physical manifestations of this condition is the "flag sign," which refers to alternating light and dark bands or stripes in the hair. This occurs due to the deficiency of protein in the diet, leading to changes in the hair’s pigmentation as well as its overall health and growth.

The presence of the flag sign serves as an important clinical indicator of protein malnutrition. The hair may also become brittle and easy to break, further reflecting the nutritional deficit. Recognizing this symptom is essential for diagnosis and timely intervention to improve the child's nutritional status.

In contrast, high energy and alertness are not associated with Kwashiorkor, as individuals suffering from this condition usually exhibit lethargy. Extreme fatigue and weakness are common symptoms, but the flag sign specifically highlights a unique physical characteristic that is emblematic of the disorder. Rapid weight gain is also not a manifestation of Kwashiorkor; rather, affected individuals may often present with edema and an appearance of fullness in the abdomen without actual weight gain due to proper nutritional intake.
