Kwashiorkor
Protein malnutrition; Protein-calorie malnutrition; Malignant malnutrition
Kwashiorkor is a form of malnutrition that occurs when there is not enough protein in the diet.
Malnutrition
Malnutrition is the condition that occurs when your body does not get enough nutrients.
Protein
Proteins are the building blocks of life. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. ...
Causes
Kwashiorkor is most common in areas where there is:
- Famine
- Limited food supply
- Low levels of education (when people do not understand how to eat a proper diet)
This disease is more common in very poor countries. It often occurs during a drought or other natural disaster, or during political unrest. These conditions are responsible for a lack of food, which leads to malnutrition.
Kwashiorkor is very rare in children in the United States. There are only isolated cases. However, one government estimate suggests that as many as 50% of elderly people in nursing homes in the United States do not get enough protein in their diet.
When kwashiorkor does occur in the United States, it is most often a sign of child abuse and severe neglect.

Treatment
Getting more calories and protein will correct kwashiorkor, if treatment is started early enough. However, children who have had this condition will never reach their full potential for height and growth.
Treatment depends on the severity of the condition. People who are in shock need treatment right away to restore blood volume and maintain blood pressure.
Calories are given first in the form of carbohydrates , simple sugars , and fats. Proteins are started after other sources of calories have already provided energy. Vitamin and mineral supplements are essential.
Carbohydrates
Carbohydrates are one of the main nutrients in our diet. They help provide energy for our body. There are three main types of carbohydrates found i...

Since the person will have been without much food for a long period of time, eating can cause problems, especially if the calories are too high at first. Food must be reintroduced slowly.
Many malnourished children will develop intolerance to milk sugar ( lactose intolerance ). They will need to be given supplements with the enzyme lactase so that they can tolerate milk products.
Lactose intolerance
Lactose is a type of sugar found in milk and other dairy products. An enzyme called lactase is needed by the body to digest lactose. Lactose intoler...

Outlook (Prognosis)
Getting treatment early generally leads to good results. Treating kwashiorkor in its late stages will improve the child's general health. However, the child may be left with permanent physical and mental problems. If treatment is not given or comes too late, this condition is life threatening.
Possible Complications
Complications may include:
-

When to Contact a Medical Professional
Call your health care provider if your child has symptoms of kwashiorkor.
Prevention
To prevent kwashiorkor, make sure the diet has enough carbohydrates, fat (at least 10% of total calories), and protein (12% of total calories).

Kwashiorkor symptoms - illustration
Kwashiorkor is a condition resulting from inadequate protein intake. Early symptoms include fatigue, irritability, and lethargy. As protein deprivation continues, one sees growth failure, loss of muscle mass, generalized swelling (edema), and decreased immunity. A large, protuberant belly is common. The incidence of kwashiorkor in children in the United States is extremely small and it is typically found in countries where there is drought and famine.
