Chapter 24: Problem 22
Kwashiorkor is a protein-deficiency disease that occurs most commonly in small children, who characteristically have thin arms and legs and bloated, distended abdomens due to fluid imbalance. When such children are placed on adequate diets, they tend to lose weight at first. Explain this observation.
Short Answer
Expert verified
Initial weight loss occurs due to the reduction of fluid retention when protein deficiency is corrected.
Step by step solution
01
- Understand Kwashiorkor
Kwashiorkor is a malnutrition condition primarily due to severe protein deficiency. It commonly affects children and is characterized by symptoms such as thin arms and legs and a bloated, distended abdomen due to fluid retention and imbalance.
02
- Protein's Role in Body Function
Proteins play crucial roles in maintaining muscle mass and proper fluid balance in the body. Without adequate protein, the body cannot produce enough plasma proteins like albumin, leading to fluid retention and edema (swelling).
03
- Initial Weight Loss on Adequate Diet
When children with Kwashiorkor are given an adequate diet rich in protein, their bodies begin to correct the protein deficiency. This leads to the production of plasma proteins, which help to reduce fluid retention. As the excess fluid is eliminated and muscle mass is gradually restored, there is an initial apparent weight loss.
04
- Long-term Weight Gain
Although there is an initial weight loss due to the reduction of fluid retention, over time, with continuous proper nutrition, the children start to gain healthy weight as their muscle mass increases and overall health improves.

Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Protein Deficiency
Protein deficiency occurs when the body doesn't get enough proteins from the diet. Proteins are vital for growth, repair, and maintaining body functions. They are made of amino acids, which act as the building blocks for our muscles, enzymes, and hormones.
Symptoms of protein deficiency include muscle wasting, weakness, susceptibility to infections, and stunted growth in children. Kwashiorkor is a severe form of protein deficiency, specifically affecting children in developing countries.
To prevent protein deficiency, incorporate a variety of protein-rich foods like meats, dairy products, legumes, and nuts into your diet. For those with dietary restrictions or food allergies, plant-based protein sources such as beans, lentils, tofu, and quinoa can be excellent alternatives.

Malnutrition
Malnutrition occurs when the body doesn't receive enough nutrients to function correctly. This can be due to a lack of food or poor-quality diets lacking essential nutrients like proteins, vitamins, and minerals.
There are two main types of malnutrition: undernutrition, which includes wasting (low weight for height), stunting (low height for age), and underweight (low weight for age); and overnutrition, which leads to obesity and related diseases.
Kwashiorkor is a form of undernutrition caused by severe protein deficiency. Symptoms include edema, an enlarged liver, and skin changes. Tackling malnutrition involves ensuring a balanced diet that meets all nutritional needs and addressing any underlying causes like poverty, lack of education, or food scarcity. Public health initiatives and nutrition education are crucial in combating malnutrition globally.

Fluid Imbalance
Fluid imbalance is a condition where the amount of water and electrolytes in the body are not in proper proportion. It can lead to dehydration or fluid overload.
In the context of Kwashiorkor, fluid imbalance manifests as edema, where excess fluid accumulates in the tissues. This happens due to the lack of plasma proteins, such as albumin, which help maintain the osmotic balance that keeps fluid within the blood vessels.
Correcting fluid imbalance involves restoring proper nutrition and protein intake, which allows the body to produce enough plasma proteins and regulate fluid distribution. Drinking adequate amounts of water and maintaining a balanced intake of electrolytes are also important to prevent fluid imbalance.

Plasma Proteins
Plasma proteins like albumin are crucial for maintaining the body's fluid balance and transporting substances throughout the blood. They are produced mainly in the liver and include a variety of proteins with different functions.
Albumin, one of the key plasma proteins, helps maintain the osmotic pressure that keeps fluid within the blood vessels. A deficiency in albumin due to inadequate protein intake leads to edema, as fluids leak into the surrounding tissues.
Restoring plasma protein levels involves increasing dietary protein to support liver function. Adequate protein intake ensures that the body can produce sufficient plasma proteins to maintain fluid balance and perform other vital functions.

Edema
Edema is the swelling caused by excess fluid trapped in the body's tissues. It often affects the legs, ankles, and feet but can also occur in other parts of the body.
In Kwashiorkor, edema occurs due to protein deficiency. Without enough plasma proteins like albumin, the osmotic pressure that retains fluid within blood vessels drops, causing fluids to move into tissues.
Managing edema in the context of Kwashiorkor involves addressing the underlying protein deficiency through proper diet. As the child receives adequate protein, the body produces more plasma proteins, helping to reduce fluid retention and swelling. Monitoring fluid intake and ensuring proper nutrition are key steps in preventing and treating edema.
