What is protein energy malnutrition PEM?

Specialty. Endocrinology. Protein–energy malnutrition (PEM) is a form of malnutrition that is defined as a range of pathological conditions arising from coincident lack of dietary protein and/or energy (calories) in varying proportions. The condition has mild, moderate, and severe degrees.

Keeping this in consideration, what causes protein energy malnutrition?

Pathobiology. Primary protein-energy malnutrition is caused by lack of access to adequate nutrient intake and usually affects children and elderly persons. The functional and structural abnormalities associated with primary protein-energy malnutrition are often reversible with nutritional therapy.

One may also ask, what is PEM name two form of PEM with their causes? Types of PEM Primary PEM results from a diet that lacks sufficient sources of protein. Marasmus, a PEM disorder, is caused by total calorie/energy depletion rather than primarily protein calorie/energy depletion. Marasmus is characterized by stunted growth and wasting of muscle and tissue.

Likewise, people ask, what are the symptoms of protein energy malnutrition?

Clinical signs and symptoms of protein-energy malnutrition (PEM) include the following:

Poor weight gain.
Slowing of linear growth.
Behavioral changes - Irritability, apathy, decreased social responsiveness, anxiety, and attention deficits.

What foods prevent protein energy malnutrition?

Preventing malnutrition plenty of fruit and vegetables. plenty of bread, rice, potatoes, pasta and other starchy foods. some milk and dairy foods. some meat, fish, eggs, beans and other non dairy sources of protein.

How is protein energy malnutrition treated?

In both children and adults, the first step in the treatment of protein-energy malnutrition (PEM) is to correct fluid and electrolyte abnormalities and to treat any infections. The most common electrolyte abnormalities are hypokalemia, hypocalcemia, hypophosphatemia, and hypomagnesemia.

What is considered severe malnutrition?

For example, according to the criteria for the acute context, 1% weight loss in one week with caloric intake less than 75% of needs constitutes malnutrition, while 2% weight loss in one week with caloric intake less than 50% of needs for five days would represent severe malnutrition.

What are the two major forms of protein energy malnutrition?

Kwashiorkor and marasmus are the two forms of protein energy malnutrition.

What are the 4 types of malnutrition?

Various forms of malnutrition

There are 4 broad sub-forms of undernutrition: wasting, stunting, underweight, and deficiencies in vitamins and minerals.
Low weight-for-height is known as wasting.
Low height-for-age is known as stunting.
Children with low weight-for-age are known as underweight.

What are the different types of protein energy malnutrition?

Types include: Kwashiorkor (protein malnutrition predominant) Marasmus (deficiency in calorie intake) Marasmic kwashiorkor (marked protein deficiency and marked calorie insufficiency signs present, sometimes referred to as the most severe form of malnutrition)

What are major causes of malnutrition?

Causes of malnutrition include inappropriate dietary choices, a low income, difficulty obtaining food, and various physical and mental health conditions. Undernutrition is one type of malnutrition. It occurs when the body does not get enough food.

What is a protein deficiency called?

Kwashiorkor is a severe form of malnutrition associated with a deficiency in dietary protein. The extreme lack of protein causes an osmotic imbalance in the gastro-intestinal system causing swelling of the gut diagnosed as an edema or retention of water.

Is malnutrition reversible?

These forms of protein-energy malnutrition in children can be pictured like this: Wasting and stunting are very different forms of malnutrition. Wasting results from an acute shortage of food, is reversible with refeeding, and has a relatively high mortality rate.

How do you test for protein deficiency?

A doctor can perform a set of blood tests known as a total protein, albumin, and albumin/globulin (A/G) ratio. Albumin and globulin are two proteins that the liver produces. This test can reveal whether total protein levels are low and if albumin and globulin proteins are at optimal levels.

What are the signs of marasmus?

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.

Other symptoms include:

persistent dizziness.
lack of energy.
dry skin.
brittle hair.

What diseases are caused by protein deficiency?

Based on available literature the researcher arrived at conclusion that insufficient of protein may cause various health problems such as kwashiorkor, marasmus, impaired mental health, edema, organ failure, wasting and shrinkage of muscle tissues, and weakness of immune system.

What is the first sign of malnutrition?

Some signs and symptoms of malnutrition include: a lack of appetite or interest in food or drink. tiredness and irritability. an inability to concentrate.

What is the most often ignored form of protein energy malnutrition?

Features of chronic malnutrition include stunted growth, mental apathy, developmental delay, and poor weight gain. Acute malnutition manifests itself in two major forms: marasums (the most common form) and kwashiorkor, although some patients' condition may manifest as a combination of both forms (marasmic kwashiorkor).

What happens if you get too much protein?

High-protein diets may tout weight loss, but this type of weight loss may only be short-term. Excess protein consumed is usually stored as fat, while the surplus of amino acids is excreted. This can lead to weight gain over time, especially if you consume too many calories while trying to increase your protein intake.

What happens when your body is low in protein?

Protein deficiency can occur when you're not eating enough protein to maintain normal body function. Not consuming enough protein can also cause muscle cramping, weakness, and soreness. Your body will take protein from muscle tissue and use it as energy to support other vital body functions when protein is low.

What are the side effects of low protein levels?

Signs and symptoms of protein deficiency

Skin, hair and nail problems.
Loss of muscle mass.
Increased risk of bone fractures.
Bigger appetite and increased calorie intake.
Risk of infections.
Fatty liver.
May inhibit proper body growth in children.

What causes marasmus?

Causes of marasmus Nutrient deficiency is the main cause of marasmus. It occurs in children that don't ingest enough protein, calories, carbohydrates, and other important nutrients. This is usually due to poverty and a scarcity of food. There are several types of malnutrition.

What is marasmus disease?

Marasmus is a form of severe malnutrition characterized by energy deficiency. It can be distinguished from kwashiorkor in that kwashiorkor is protein deficiency with adequate energy intake whereas marasmus is inadequate energy intake in all forms, including protein.

What is the term malnutrition?

Malnutrition. Malnutrition is a condition that results from eating a diet in which one or more nutrients are either not enough or are too much such that the diet causes health problems. It may involve calories, protein, carbohydrates, vitamins or minerals.
