The resolution of this question is of some importance from the point of view of public health diagnosis and prevention. A crucial point in the argument is the pathogenesis of oedema, which is discussed in some detail. Although it is clearly multifactorial, with electrolyte disturbances—potassium deficiency and sodium retention—playing an important role, it is contended that the classical theory is essentially correct.
On the dietary side, recent experimental work supports the earlier view that the development of oedema depends on a relative deficiency of protein with a relative excess of energy. Comparisons of intakes with requirements are unconvincing in view of uncertainty about the validity of the estimates of children's needs for protein.

Abstract It has been argued that the oedema of kwashiorkor is not caused by hypoalbuminaemia because the oedema disappears with dietary treatment before the plasma albumin concentration rises. Introduction Malnutrition in young children may lead to severe wasting alone marasmus , or may be associated with oedema kwashiorkor. Open in a separate window.
Figure 1. Figure 2. Measuring Plasma Albumin Concentrations Albumin concentrations can be measured accurately by using specific immunological assays that only respond to that particular protein, even at very low levels.
Figure 3. The Physiology of Kwashiorkor Looks a lot like Finnish Congenital Nephrotic Syndrome The evidence I have reviewed thus far points to the pathophysiology of kwashiorkor being a combination of severe malnutrition and a low plasma oncotic pressure due to extreme hypoalbuminaemia.
Figure 4. Conclusion The mistaken belief that the oedema of kwashiorkor is unrelated to profound hypoalbuminaemia, combined with an exaggerated concern about the risks of congestive cardiac failure, has resulted in guidelines for shock management that fail to address their physiological needs, and which has not reduced their high mortality rate.

It usually begins in the legs, but can involve the whole body, including the face. Kwashiorkor can be fatal if it's left untreated for too long because children become very vulnerable to infections. The main cause of kwashiorkor is not eating enough protein or other essential vitamins and minerals. It's most common in developing countries with a limited food supply, poor hygiene, and a lack of education about the importance of giving babies and children an adequate diet.
Kwashiorkor is rare in developed countries such as the UK, but it can occasionally happen as a result of severe neglect, long-term illness, a lack of knowledge about good nutrition, or a very restricted diet. Kwashiorkor can often be diagnosed based on a child's physical appearance and questions about their diet and care. However, a blood test and urine test may be done to rule out other conditions. This can include tests to:.
It can also be a sign of an underlying condition, such as HIV. If kwashiorkor is suspected, your doctor will first examine you to check for an enlarged liver hepatomegaly and swelling. Next, blood and urine tests may be ordered to measure the level of protein and sugar in your blood.
Other tests may be performed on your blood and urine to measure signs of malnutrition and lack of protein. These tests may look for muscle breakdown and assess kidney function, overall health, and growth. These tests include:. Kwashiorkor can be corrected by eating more protein and more calories overall, especially if treatment is started early.
You may first be given more calories in the form of carbohydrates, sugars, and fats. Once these calories provide energy, you will be given foods with proteins. Foods must be introduced and calories should be increased slowly because you have been without proper nutrition for a long period. Your body may need to adjust to the increased intake. Even with treatment, children who have had kwashiorkor may never reach their full growth and height potential.
If treatment comes too late, a child may have permanent physical and mental disabilities. Kwashiorkor can be prevented by making sure you eat enough calories and protein-rich foods.
