Malnutrition
Definition:-
Malnutrition is defined as imbalance between the
body’s need and the intake of nutrients, which can lead to
nutritional disorders.
The World Health Organization (WHO) defines malnutrition
as “the cellular imbalance between the supply of nutrients
and energy and the body’s demand for them to ensure
growth, maintenance, and specific functions.”
Causes of malnutrition
• Infectious disease
• Food taboos
• Personal choice for food
• Customs, beliefs, culture and attitude
• Cooking practices
• Lack of knowledge
• Poverty
• Poor sanitary environment
Prevention & control of malnutrition
• Identification of affected individuals
• Special feeding program
• Health education
• Promotion of breastfeeding
• Educating the selection of right kind of food
• Correction of harmful Taboo
• Decreasing the infectious disease by appropriate measures
• Kitchen gardening
• Proper planning of budget with expenditure on food
Protein energy malnutrition (PEM)
Definition:-
According to World Health Organization, protein energy malnutrition
(PEM) refers to “an imbalance between the supply of protein and
energy and the body's demand for them to ensure optimal growth
and function”.
Classification Of Protein Energy Malnutrition
PEM can be classified into two types:
Primary PEM
Secondary PEM
Primary PEM
1. Kwashiorkor
2. Marasmus
Kwashiorkor
Kwashiorkor occurs due to decreased intake of proteins
Marasms
This is a condition caused by decreased intake of total calories. A
deficiency of total calories is called as much and is often
accompanied by Kwashiorkor.
Secondary PEM
• It is caused due to disorders in the gastrointestinal tract.
• It can be caused due to infections, hyperthyroidism, trauma,
burns, and other critical illnesses.
• It decreases appetite and impairs nutrient metabolism.
Diagnosis of PEM
• PEM can be diagnosed by identifying the dietary history of the
patient.
• The measurement of height and weight, fat distribution,
anthropometric measurements of lean body mass should be
examined.
• The Body Mass Index or BMI is calculated to measure the severity of
PEM.
Treatment of PEM
• Protein Energy Malnutrition can be treated in the following ways:
• Oral feeding
• Avoiding lactose
• Reduction in poverty
• Improving nutritional education and public health measures
• Multivitamin supplements
• Treat infections and fluid and electrolyte abnormalities, in severe
cases
Body mass index(BMI)
• BMI is a person's weight in kilograms (kg) divided by his or her
height in meters squared.
Formula to calculate BMI
Anaemia
Definition:-
Anaemia is a condition in which the number of red
blood cells or the haemoglobin concentration within them is
lower than normal.
Iron deficiency anaemia
• Anaemia is defined as a reduction in the oxygen-carrying capacity of the
blood caused by a diminished erythrocyte mass.
• Iron deficiency anaemia develops when body stores of iron drop too low
to support normal red blood cell (RBC) production. Inadequate dietary iron,
iron absorption, bleeding, or loss of body iron in the urine maybe the
cause.
• HGB<13.5 g/dL (men) <12 (women)
• HCT<41% (men) <36 (women)
• a ferritin concentration of more than 100 ng/mL (100 mg/L)effectively
rules out iron deficiency, and a ferritin of less than 15ng/mL (15 mg/L) rules
in iron deficiency.
• More common in women as a result of menstrual losses
Causes of iron deficiency anaemia
• Inadequate intake of Iron.
• Malabsorption of iron due to hypochlorhydria &
diarrhoea.
• Increased requirement of iron in a growing child & in
pregnancy.
• Increased loss of iron due to injury, recurrent epistaxis
& peptic ulcer.
• Chronic blood loss such as menustrual & menopausal
bleeding parturition.
• Subtotal or complete gastrectomy.
Iron requirements
• Children 1mg per day
• Males 0.5-1mg per day
• Menstruating females 1-2mg per day
• Pregnant females 1.5-2.5mg per day
• An adequate diet contains 15mg of iron, 10% of which is
absorbed.
• Normal plasma iron: 80 – 120 μg.
Clinical features
• Pallor of the skin
• Fatigue and weakness
• Anxiety
• Irritability
• Sleepiness
• Palpitations
• Hair loss
• Fainting
• Depression
• Breathlessness
Treatment of IDA
• Iron supplements and with ferrous sulphate for ferrous
gluconate
• Vitamin c may aid in the body’s ability to absorb iron.
• Vitamin supplements are to be given orally (Folic acid and
vitamin b12)
• In severe cases blood transfusion may be necessary.
• Intake of iron rich diet.
• Nutrition education.
Hypertension
Definition:-
Hypertension (HTN or HT), also known as high blood
pressure (HBP), is a long term medical condition in which the
blood pressure in the arteries is persistently elevated.
The SBP will be more than or equal of 140 mmHg and DBP
will be more than or equal of 90 mmHg.

  • 5. Malnutrition Definition:- Malnutrition is defined as imbalance between the body’s need and the intake of nutrients, which can lead to nutritional disorders. The World Health Organization (WHO) defines malnutrition as “the cellular imbalance between the supply of nutrients and energy and the body’s demand for them to ensure growth, maintenance, and specific functions.”
  • 6. Causes of malnutrition • Infectious disease • Food taboos • Personal choice for food • Customs, beliefs, culture and attitude • Cooking practices • Lack of knowledge • Poverty • Poor sanitary environment
  • 7. Prevention & control of malnutrition • Identification of affected individuals • Special feeding program • Health education • Promotion of breastfeeding • Educating the selection of right kind of food • Correction of harmful Taboo • Decreasing the infectious disease by appropriate measures • Kitchen gardening • Proper planning of budget with expenditure on food
  • 8. Protein energy malnutrition (PEM) Definition:- According to World Health Organization, protein energy malnutrition (PEM) refers to “an imbalance between the supply of protein and energy and the body's demand for them to ensure optimal growth and function”.
  • 9. Classification Of Protein Energy Malnutrition PEM can be classified into two types: Primary PEM Secondary PEM Primary PEM 1. Kwashiorkor 2. Marasmus
  • 10. Kwashiorkor Kwashiorkor occurs due to decreased intake of proteins Marasms This is a condition caused by decreased intake of total calories. A deficiency of total calories is called as much and is often accompanied by Kwashiorkor.
  • 11. Secondary PEM • It is caused due to disorders in the gastrointestinal tract. • It can be caused due to infections, hyperthyroidism, trauma, burns, and other critical illnesses. • It decreases appetite and impairs nutrient metabolism.
  • 12. Diagnosis of PEM • PEM can be diagnosed by identifying the dietary history of the patient. • The measurement of height and weight, fat distribution, anthropometric measurements of lean body mass should be examined. • The Body Mass Index or BMI is calculated to measure the severity of PEM.
  • 13. Treatment of PEM • Protein Energy Malnutrition can be treated in the following ways: • Oral feeding • Avoiding lactose • Reduction in poverty • Improving nutritional education and public health measures • Multivitamin supplements • Treat infections and fluid and electrolyte abnormalities, in severe cases
  • 14. Body mass index(BMI) • BMI is a person's weight in kilograms (kg) divided by his or her height in meters squared.

  • 17. Iron deficiency anaemia • Anaemia is defined as a reduction in the oxygen-carrying capacity of the blood caused by a diminished erythrocyte mass. • Iron deficiency anaemia develops when body stores of iron drop too low to support normal red blood cell (RBC) production. Inadequate dietary iron, iron absorption, bleeding, or loss of body iron in the urine maybe the cause. • HGB<13.5 g/dL (men) <12 (women) • HCT<41% (men) <36 (women) • a ferritin concentration of more than 100 ng/mL (100 mg/L)effectively rules out iron deficiency, and a ferritin of less than 15ng/mL (15 mg/L) rules in iron deficiency. • More common in women as a result of menstrual losses
  • 18. Causes of iron deficiency anaemia • Inadequate intake of Iron. • Malabsorption of iron due to hypochlorhydria & diarrhoea. • Increased requirement of iron in a growing child & in pregnancy. • Increased loss of iron due to injury, recurrent epistaxis & peptic ulcer. • Chronic blood loss such as menustrual & menopausal bleeding parturition. • Subtotal or complete gastrectomy.
  • 19. Iron requirements • Children 1mg per day • Males 0.5-1mg per day • Menstruating females 1-2mg per day • Pregnant females 1.5-2.5mg per day • An adequate diet contains 15mg of iron, 10% of which is absorbed. • Normal plasma iron: 80 – 120 μg.
  • 20. Clinical features • Pallor of the skin • Fatigue and weakness • Anxiety • Irritability • Sleepiness • Palpitations • Hair loss • Fainting • Depression • Breathlessness
  • 21. Treatment of IDA • Iron supplements and with ferrous sulphate for ferrous gluconate • Vitamin c may aid in the body’s ability to absorb iron. • Vitamin supplements are to be given orally (Folic acid and vitamin b12) • In severe cases blood transfusion may be necessary. • Intake of iron rich diet. • Nutrition education.
  • 22. Hypertension Definition:- Hypertension (HTN or HT), also known as high blood pressure (HBP), is a long term medical condition in which the blood pressure in the arteries is persistently elevated. The SBP will be more than or equal of 140 mmHg and DBP will be more than or equal of 90 mmHg.
