What is kwashiorkor?
Kwashiorkor is a type of malnutrition that is rare in the United States; it is most common in areas of drought and famine. Kwashiorkor is due to inadequate protein in the diet despite an adequate caloric intake. Symptoms may include irritability and fatigue followed by slowed growth, weight loss, muscle wasting, generalized swelling, skin changes, enlargement of the liver and abdomen, and weakening of the immune system, leading to frequent infections. Once kwashiorkor develops, some of the effects, such as short stature and intellectual disability, cannot be corrected.
Children are affected by kwashiorkor more frequently than adults. It typically starts after the child has been weaned and breast milk has been replaced with a diet low in protein, although it can occur in infants if the mother is protein-deprived. Kwashiorkor can also occur due to parasites and infections that can interfere with nutritional status. Low protein diets associated with dietary changes due to milk allergies in infants, fad diets, poor nutritional education, or a chaotic home life, are other causes of kwashiorkor.
Kwashiorkor can be prevented by including foods in your diet that are rich in proteins, such as meat, fish, dairy products, eggs, soy, and beans. Treatment involves slow increases in calories from carbohydrates, sugars, and fats, followed by protein. Vitamin and mineral supplements and enzymes to help digest dairy products are often needed. Treatment also involves correction of any fluid and electrolyte imbalances and treatment of any infections.
Although kwashiorkor is not common in the United States, protein deficiency can occur with prolonged hospitalization or in nursing home residents. It is estimated that up to half of the elderly living in nursing homes have diets low in protein (Source: PubMedHealth).
Left untreated, kwashiorkor can cause life-threatening shock and coma. Seek immediate medical care (call 911) for serious symptoms, such as profuse sweating, bluish coloration of the lips or fingernails, chest pain, cold and clammy skin, rapid or shallow breathing, rapid heart rate (tachycardia), weakness, decreased or absent urine output, fever, unusual anxiety, or confusion or loss of consciousness for even a brief moment. Seek prompt medical care if any symptoms of kwashiorkor occur.
What are the symptoms of kwashiorkor?
Early symptoms of kwashiorkor include irritability and fatigue. As the condition continues, additional symptoms include slowed growth, weight loss, muscle wasting, generalized swelling, skin changes, enlargement of the liver and abdomen, and weakening of the immune system, leading to frequent infections.
Common symptoms of kwashiorkor
Kwashiorkor symptoms may develop slowly over time. Common symptoms include:
Abdominal swelling, distension or bloating
Diarrhea
Enlarged liver
Fatigue
Frequent infections
Generalized swelling
Hair and nail changes, including brittle, reddish hair and ridged nails that are thin and soft
Irritability
Muscle wasting
Skin changes, including pigment loss, red or purple patches, peeling, cracking, skin sloughing, and the development of sores
Slowed growth leading to short stature
Weight loss
Serious symptoms that might indicate a life-threatening condition
In some cases, kwashiorkor can be life threatening. Seek immediate medical care (call 911) if you, or someone you are with, have any of these life-threatening symptoms including:
Bluish coloration of the lips or fingernails
Change in level of consciousness or alertness, such as passing out or unresponsiveness
Chest pain, chest tightness, chest pressure, palpitations
Cold and clammy skin
High fever (higher than 101 degrees Fahrenheit)
Not producing any urine, or an infant who does not produce the usual amount of wet diapers
Profuse sweating
Rapid heart rate (tachycardia)
Respiratory or breathing problems, such as shortness of breath, difficulty breathing, labored breathing, shallow breathing, or not breathing
What causes kwashiorkor?
Kwashiorkor is caused by a diet low in protein. It can also arise due to infections, parasites, or other conditions that interfere with protein absorption from the gastrointestinal tract. It is most common in children living in areas hit by drought and famine, but it can be related to dietary changes due to milk allergies in infants, fad diets, poor nutritional education, or a chaotic home life.
What are the risk factors for kwashiorkor?
A number of factors increase the risk of developing kwashiorkor. Not all people with risk factors will get kwashiorkor. Risk factors for kwashiorkor include:
Conditions that interfere with protein absorption such as cystic fibrosis
Dietary changes for management of milk allergies in infants and children
Diets that are low in protein such as a vegan diet
Drought or famine
Infections that interfere with protein absorption
Limited food supply, as may occur during political unrest
Parasites such as intestinal worms
Poor education about proper nutrition
Prolonged hospitalization or residence in a nursing home
How is kwashiorkor treated?
Treatment of kwashiorkor depends upon its severity. Fluid and electrolyte imbalances may need to be corrected with intravenous fluids, and infections may require treatment with antibiotics.
Although the goal is to increase protein in the diet, rapid increases in calories and protein can be dangerous. Often, the calories are slowly increased by adding carbohydrates, sugars, and fat to the diet. Next, protein is gradually added. People who have malnutrition may have difficulty digesting the lactose in dairy products, so the enzyme lactase may be added. Vitamin and mineral supplements may also be used.
Common treatments for kwashiorkor
Common treatments for kwashiorkor include:
Antibiotics to treat infections
Gradual increases in dietary calories from carbohydrates, sugars and fats
Gradual increases in dietary protein
Intravenous fluids to correct fluid and electrolyte imbalances
Lactase to assist in digestion of dairy products
Vitamin and mineral supplements to treat deficiencies
What are the potential complications of kwashiorkor?
In some people, especially infants and children, complications of untreated or poorly controlled kwashiorkor can be serious, even life threatening in some cases. You can help minimize your risk of serious complications by following the treatment plan you and your health care professional design specifically for you. Complications of kwashiorkor include:
Anemia (low red blood cell count)
Coma
Frequent infections
Intellectual disability
Physical disability
Poor wound healing
Shock
Short stature
Skin pigmentation changes
Steatohepatitis (fatty liver)
