The defining sign of kwashiorkor in a malnourished child is pedal edema (swelling of the feet). Other signs include a distended abdomen, an enlarged liver with fatty infiltrates, thinning hair, loss of teeth, skin depigmentation and dermatitis. Children with kwashiorkor often develop irritability and anorexia.
Victims of kwashiorkor fail to produce antibodies following vaccination against diseases, including diphtheria and typhoid.Generally, the disease can be treated by adding food energy and protein to the diet; however, it can have a long-term impact on a child's physical and mental development, and in severe cases may lead to death.
