Kwashiorkor is a dangerous, overlooked form of malnutrition that is often seen in young children of communities facing food shortages, famine, or lack of nutritional awareness. The worst part is that even if children are getting enough calories, they can still get this disease. This is because they are not getting the protein their body needs to grow and heal. Read on to learn more.
Kwashiorkor disease is a severe form of malnutrition caused by a dangerously low intake of protein. It’s most common in areas affected by famine or extreme poverty, where children often survive on starchy foods that lack essential nutrients. One of the most visible signs of kwashiorkor is swelling, especially in the belly, feet, and ankles, while the rest of the body appears alarmingly thin and wasted. The liver also becomes enlarged due to fat accumulation.
If caught early, recovery is possible with proper medical care, including a diet rich in calories and high-quality protein. But when left untreated, kwashiorkor can lead to lasting damage, slowed growth, developmental delays, or even coma. In its most severe form, it can be life-threatening, especially for young children. Early intervention can make all the difference.
Kwashiorkor's meaning lies in the body’s response to a protein-deficient diet, despite adequate or near-adequate calorie consumption. Unlike starvation, where fat and muscle wasting is prominent, children with kwashiorkor appear swollen due to fluid retention caused by low plasma protein levels.
Kwashiorkor severely affects a child’s body, appearance, and behaviour. Common kwashiorkor symptoms include:
The condition often follows illnesses like diarrhoea or pneumonia, which drain the body’s nutrients. Signs like loss of appetite, apathy, and fluid retention are classic indicators. Early detection is vital to prevent lasting damage or death.
Causes of Kwashiorkor
Now, let’s take a look at the causes of kwashiorkor.
Kwashiorkor develops when the body doesn’t get enough protein, a nutrient essential for building and repairing cells, especially during periods of rapid growth like childhood or pregnancy. Proteins do more than just help with growth; they also play a key role in maintaining the body’s fluid balance. Without enough protein, fluid starts to leak out of blood vessels and collects in the tissues, leading to the swelling and puffiness (oedema) that’s often seen in this condition.
While kwashiorkor is extremely rare in developed countries like the UK or the US, it can still occur in cases of severe neglect, chronic illness, or restrictive diets where essential nutrients are missing, often due to a lack of awareness or access to proper nutrition.
Understanding the difference between kwashiorkor and marasmus is vital for accurate diagnosis and treatment. Both are forms of severe malnutrition, but they differ significantly in clinical presentation and underlying causes.
Diagnosing Kwashiorkor is often straightforward, starting with a child’s physical appearance, like a swollen belly, thin limbs, or flaky skin, and a discussion of their diet and living conditions. To confirm the diagnosis and rule out other conditions, doctors may order blood and urine tests to check protein, blood sugar, vitamin, and mineral levels. Liver and kidney function are also evaluated. In some cases, growth measurements, BMI, body water content, or even hair and skin samples are examined. Early and accurate diagnosis is crucial to begin life-saving treatment and prevent long-term complications.
In its early stages, kwashiorkor can be treated with milk-based therapeutic feeds or RUTF (Ready-to-Use Therapeutic Food), a high-energy mix of peanut butter, milk powder, oil, sugar, and essential vitamins and minerals. If complications like infections or dehydration are present, hospital care is required.
Treatment focuses on stabilising the child:
Feeding is reintroduced gradually, starting with small portions and increasing over time. With proper care, children often begin to improve within a week, though full recovery typically takes 2 to 6 weeks. Early intervention can make all the difference in saving a life.
