Protein-energy malnutrition (PEM) contains 3 forms
kwashiorkor (KW) marasmus
marasmic KW
PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Skin pigmentation
Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes
Body composition
Body mass Body mass is significantly decreased
Fat stores can decrease to as low as 5 of the body
weight and be macroscopically undetectable
The remaining fat is usually stored in the liver
body water The proportion of water increases
proportion of extracellular water also increases
resulting in edema
protein mass can decrease up to 30
The muscle fibers are thin Muscle cells are atrophic
Other organ mass
The brain skeleton and kidney are
preserved whereas the liver heart
pancreas and digestive tract are first
affected
bull This is typically a disease of impoverished
countries because of drought or political
turmoil bull Improving calorie and protein intake will
correct it treatment is not started too late bull Full height and growth potential will never be
achieved in children bull Severe kwashiorkor may leave a child with
permanent mental and physical disabilities
Monkey face
Excess protein can cause problems as well
such as causing the immune system to overreact
liver dysfunction from increased toxic residues
bone loss due to increased acidity in the blood
diet high in meat could lead to high cholesterol or
other diseases such as gout
Another potential problem is that may put a strain on
the kidneys

Protein-energy malnutrition (PEM) contains 3 forms
kwashiorkor (KW) marasmus
marasmic KW
PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Skin pigmentation
Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes
Body composition
Body mass Body mass is significantly decreased
Fat stores can decrease to as low as 5 of the body
weight and be macroscopically undetectable
The remaining fat is usually stored in the liver
body water The proportion of water increases
proportion of extracellular water also increases
resulting in edema
protein mass can decrease up to 30
The muscle fibers are thin Muscle cells are atrophic
Other organ mass
The brain skeleton and kidney are
preserved whereas the liver heart
pancreas and digestive tract are first
affected
bull This is typically a disease of impoverished
countries because of drought or political
turmoil bull Improving calorie and protein intake will
correct it treatment is not started too late bull Full height and growth potential will never be
achieved in children bull Severe kwashiorkor may leave a child with
permanent mental and physical disabilities
Monkey face
Excess protein can cause problems as well
such as causing the immune system to overreact
liver dysfunction from increased toxic residues
bone loss due to increased acidity in the blood
diet high in meat could lead to high cholesterol or
other diseases such as gout
Another potential problem is that may put a strain on
the kidneys

Protein-energy malnutrition (PEM) contains 3 forms
kwashiorkor (KW) marasmus
marasmic KW
PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes

Protein-energy malnutrition (PEM) contains 3 forms
kwashiorkor (KW) marasmus
marasmic KW
PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Skin pigmentation
Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes
Body composition
Body mass Body mass is significantly decreased
Fat stores can decrease to as low as 5 of the body
weight and be macroscopically undetectable
The remaining fat is usually stored in the liver
body water The proportion of water increases
proportion of extracellular water also increases
resulting in edema
protein mass can decrease up to 30
The muscle fibers are thin Muscle cells are atrophic
Other organ mass
The brain skeleton and kidney are
preserved whereas the liver heart
pancreas and digestive tract are first
affected
bull This is typically a disease of impoverished
countries because of drought or political
turmoil bull Improving calorie and protein intake will
correct it treatment is not started too late bull Full height and growth potential will never be
achieved in children bull Severe kwashiorkor may leave a child with
permanent mental and physical disabilities
Monkey face
Excess protein can cause problems as well
such as causing the immune system to overreact
liver dysfunction from increased toxic residues
bone loss due to increased acidity in the blood
diet high in meat could lead to high cholesterol or
other diseases such as gout
Another potential problem is that may put a strain on
the kidneys

Protein-energy malnutrition (PEM) contains 3 forms
kwashiorkor (KW) marasmus
marasmic KW
PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes

marasmic KW
PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Skin pigmentation
Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes
Body composition
Body mass Body mass is significantly decreased
Fat stores can decrease to as low as 5 of the body
weight and be macroscopically undetectable
The remaining fat is usually stored in the liver
body water The proportion of water increases
proportion of extracellular water also increases
resulting in edema
protein mass can decrease up to 30
The muscle fibers are thin Muscle cells are atrophic
Other organ mass
The brain skeleton and kidney are
preserved whereas the liver heart
pancreas and digestive tract are first
affected
bull This is typically a disease of impoverished
countries because of drought or political
turmoil bull Improving calorie and protein intake will
correct it treatment is not started too late bull Full height and growth potential will never be
achieved in children bull Severe kwashiorkor may leave a child with
permanent mental and physical disabilities
Monkey face
Excess protein can cause problems as well
such as causing the immune system to overreact
liver dysfunction from increased toxic residues
bone loss due to increased acidity in the blood
diet high in meat could lead to high cholesterol or
other diseases such as gout
Another potential problem is that may put a strain on
the kidneys

Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes
Body composition
Body mass Body mass is significantly decreased
Fat stores can decrease to as low as 5 of the body
weight and be macroscopically undetectable
The remaining fat is usually stored in the liver
body water The proportion of water increases
proportion of extracellular water also increases
resulting in edema
protein mass can decrease up to 30
The muscle fibers are thin Muscle cells are atrophic
Other organ mass
The brain skeleton and kidney are
preserved whereas the liver heart
pancreas and digestive tract are first
affected
bull This is typically a disease of impoverished
countries because of drought or political
turmoil bull Improving calorie and protein intake will
correct it treatment is not started too late bull Full height and growth potential will never be
achieved in children bull Severe kwashiorkor may leave a child with
permanent mental and physical disabilities
Monkey face
Excess protein can cause problems as well
such as causing the immune system to overreact
liver dysfunction from increased toxic residues
bone loss due to increased acidity in the blood
diet high in meat could lead to high cholesterol or
other diseases such as gout
Another potential problem is that may put a strain on
the kidneys

marasmic KW
PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes

PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes
Body composition
Body mass Body mass is significantly decreased
Fat stores can decrease to as low as 5 of the body
weight and be macroscopically undetectable
The remaining fat is usually stored in the liver
body water The proportion of water increases
proportion of extracellular water also increases
resulting in edema
protein mass can decrease up to 30

Excess protein can cause problems as well
such as causing the immune system to overreact
liver dysfunction from increased toxic residues
bone loss due to increased acidity in the blood
diet high in meat could lead to high cholesterol or

Protein-energy malnutrition (PEM) contains 3 forms
kwashiorkor (KW) marasmus
marasmic KW
PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes
Body composition
Body mass Body mass is significantly decreased
Fat stores can decrease to as low as 5 of the body
weight and be macroscopically undetectable
The remaining fat is usually stored in the liver
body water The proportion of water increases
proportion of extracellular water also increases
resulting in edema
protein mass can decrease up to 30

Excess protein can cause problems as well
such as causing the immune system to overreact
liver dysfunction from increased toxic residues
bone loss due to increased acidity in the blood
diet high in meat could lead to high cholesterol or
other diseases such as gout

Protein-energy malnutrition (PEM) contains 3 forms
kwashiorkor (KW) marasmus
marasmic KW
PEM represent a group of pathologic conditions
associated with a nutritional and energy deficit occurring mainly in young children from developing countries at the time of weaning frequently associated with infections mainly gastrointestinal infections
Kwashiorkor occurs in areas of famine limited food supply and low levels of education lead to inadequate knowledge of proper dietEarly symptoms are fatigue irritability and lethargy As protein deprivation continues growth failure loss of muscle mass generalized swelling (edema) decreased immunity occur A large protuberant belly is common Skin conditions (such as dermatitis changes in pigmentation thinning of hair and vitiligo) are seen frequently Shock and coma precede death

Marasmus resulting from an insufficient nutritional intake
associated with acute conditions (gastroenteritis)
or chronic conditions (eg tuberculosis HIV infection)
Marasmus results from a negative energy balance a decreased energy intake increased energy expenditure or both Children adapt to an energy deficit with a decrease in physical activity lethargy a decrease in basal energy metabolism slowing of growth and finally weight loss Pathophysiological changes associated with nutritional and energy deficits can be described as (1) body composition changes (2) metabolic changes and (3) anatomic changes
Body composition
Body mass Body mass is significantly decreased
Fat stores can decrease to as low as 5 of the body
weight and be macroscopically undetectable
The remaining fat is usually stored in the liver
body water The proportion of water increases
proportion of extracellular water also increases
resulting in edema
protein mass can decrease up to 30

Excess protein can cause problems as well
such as causing the immune system to overreact
liver dysfunction from increased toxic residues
bone loss due to increased acidity in the blood
diet high in meat could lead to high cholesterol or
