- A child whose weight-for-age is less than −2 SD is considered underweight, and one whose weight-for-height is less than −2 SD is deemed wasted. Stunting results from chronic undernutrition, which retards linear growth, whereas wasting results from inadequate nutrition over a shorter period, and underweight encompasses both stunting and wasting.

Stunting results from chronic undernutrition, which retards linear growth, whereas wasting results from inadequate nutrition over a shorter period, and underweight encompasses both stunting and wasting. Typically, growth faltering begins at about six months of age, as children transition to foods that are often inadequate in quantity and ...

Wasting and stunting represent 2 different ways to adapt to suboptimal growth conditions, either by restraining ponderal or linear growth. What drives children to restrict growth in one or other of these ways seems to vary with age but remains largely unknown.

Marasmus is a form of malnutrition. Symptoms of marasmus include wasting, or the loss of body fat and muscle. A child with marasmus may not grow as children usually do and experience stunted growth.
Malnutrition happens when the intake of nutrients and energy is too low for a person’s needs. This low intake of nutrients can cause health problems, usually because a person’s diet does not contain all the vitamins and nutrients that the body needs to function.
When an individual does not get the right nutrients, it is harder for their body to carry out routine processes that enable them to grow new cells or fight disease. More serious health problems can then result.
In many parts of the world, marasmus happens because people do not have enough food. In developed countries, it can occur as a result of the eating disorder anorexia nervosa.
Marasmus is a severe form of protein-energy malnutrition that results when a person does not consume enough protein and calories. Without these vital nutrients, energy levels become dangerously low and vital functions begin to stop.
Both adults and children can have marasmus, but it most often affects young children in developing countries.
Causes of marasmus include:
•not having enough nutrition or having too little food
•consuming the wrong nutrients or too much of one and not enough of another
•having a health condition that makes it difficult to absorb or process nutrients correctly
Older adults who live alone and find it difficult to prepare food and care for themselves may be at risk. Sometimes marasmus can affect an older adult who has not eaten healthfully over a period of some months or years, say the University of Kansas Landon Center on Aging.
While consuming the wrong nutrients and having a health condition can contribute to marasmus, each of these alone would probably not be enough to cause it, as long as calories are available.
The primary symptom of marasmus is an acute loss of body fat and muscle tissues, leading to an unusually low body mass index (BMI). Marasmus is a type of wasting.
In a child, the main symptom of marasmus is a failure to grow, known as stunted growth.
In adults and older children, the main symptom may be wasting, or a loss of body tissue and fat. An older child with wasting may have standard height for their age.
A child with marasmus may also be very hungry and suck on their clothes or hands as if looking for something to eat.
But some people with marasmus will have anorexia, and they will not want or be able to eat.
Over time, a person with marasmus will lose body tissue and fat in their face. Similarly, their bones become visible under their skin, and folds of skin develop from the loss of body mass. Their eyes may appear sunken.
Kwashiorkor
Kwashiorkor is another severe form of protein-energy malnutrition where the main deficiency is protein. Severe cases of malnutrition can lead to kwashiorkor. Unlike marasmus, kwashiorkor causes the body to retain fluid in the lower legs, feet, arms, hands, and face, leading to a swollen appearance. Kwashiorkor may also result in a person having a distended or bulging abdomen. But, someone with kwashiorkor may not have a particularly low weight, because the fluid buildup makes up for the loss in body fat and muscle tissue. According to the United Nations (UN) Food and Agriculture Organization (FAO), a child with kwashiorkor will have a weight that is 60 to 80 percent of the standard weight for their age. Other symptoms of kwashiorkor include: •loss of appetite •lack of energy •irritability •changes in hair color to yellow or orange Skin problems are a complication of kwashiorkor. These can include: •patches of skin turning unusually light or dark •skin shedding •skin ulcers developing •lesions beginning to leak or bleed Liver problems can occur with kwashiorkor, but they are rare with marasmus. Kwashiorkor needs immediate diagnosis and treatment, as it can quickly become life-threatening.
Marasmic kwashiorkor
Marasmic kwashiorkor is the third form of protein-energy malnutrition that combines features and symptoms of both marasmus and kwashiorkor. A person with marasmic kwashiorkor may: – be extremely thin – show signs of wasting in areas of the body – have excessive fluid buildup in other parts In children with marasmus kwashiorkor, the weight will be less than 60 percent of the standard weight for their age. Immediate medical treatment is essential. As the condition progresses, recovery becomes more difficult, and the chances of survival reduce. According to the FAO, it remains unclear why some people develop marasmus, and others develop kwashiorkor.
Marasmus is a life-threatening medical emergency. When symptoms appear, the person needs treatment straight away.
Rapid weight loss, infections, and sudden changes in behavior or appetite could be signs of an underlying problem, such as an eating disorder or a chronic health condition.
A medical professional will need to prepare a specific eating plan for anyone with a diagnosis of marasmus.
If the person has anorexia nervosa, a team of professionals may be involved.
It is critical for a person with marasmus to receive a diet treatment that is rich in nutrients, carbohydrates, and calories. They will need more calories than is usual for their age. However, their body may find it hard to tolerate or digest food after losing so much fat and body tissue.
One solution is for doctors to provide food in small amounts and possibly through tubes to the veins and stomach. These tubes allow for food and fluid to be delivered quickly and directly to the body.
The best way to prevent marasmus is to have an adequate intake of calories and protein, preferably from a healthful, well-balanced diet.
Foods rich in protein, such as skimmed milk, fish, eggs, and nuts are ideal for energy and growth, though any protein and calorie-rich food can be used to prevent marasmus, depending on what is available.
Vegetables and fruits are essential for providing other nutrients and minerals and for preventing vitamin deficiencies. People can also take supplements, but they may be less effective than foods in delivering nutrients.
A person who has recovered or is recovering from marasmus should take care to avoid complications, including dehydration and diarrhea.

Wasting is the most immediate, visible and life-threatening form of malnutrition. It results from the failure to prevent malnutrition among the most vulnerable children. Children with wasting are too thin and their immune systems are weak, leaving them vulnerable to developmental delays, disease and death.
Sep 5, 2021 · Improving maternal health and nutrition in pregnancy and early life could have a critical role in the prevention of wasting and stunting. Periods of wasting leave a child more likely to experience stunting and, to a lesser extent, vice versa. Common risk factors drive an accumulation of vulnerabilities.
The patients with obstruction to the delivery of nutrients include those with malignancy of the head and neck, esophagus, or stomach; mucosal strictures; bypass of the GI tract, including fistulae which are due to malignancy or those that are surgically produced, such as those for weight reduction.
