Edema
A characteristic sign of kwashiorkor is edema, which is characterized by swollen and puffy skin. Low levels of human serum albumin, the most prevalent protein in the liquid component of blood, or blood plasma, are thought to be the reason. One of the albumin's primary jobs is to maintain oncotic pressure, which is the force that pushes fluid into the bloodstream. Albumin inhibits excessive fluid accumulation in tissues and other bodily compartments in this way.
Severe protein deficit lowers oncotic pressure due to decreased quantities of human serum albumin. As a result, fluid builds up in the tissues, producing edema. Protein deficit may also cause fluid retention in the abdominal cavity for the same reason. A bloated stomach is a common symptom of kwashiorkor. Remember that edema is a sign of severe protein shortage, which is uncommon in affluent nations.
