1. Introduction to Nutritional Deficiency Disorders
Nutritional deficiency disorders occur due to an inadequate intake, absorption, or utilization of essential nutrients. These deficiencies can lead to a wide range of health problems, affecting growth, immunity, metabolism, and organ function.
2. Types of Nutrients and Their Deficiencies
A. Macronutrient Deficiencies
Macronutrients provide energy and include carbohydrates, proteins, and fats.
1. Protein-Energy Malnutrition (PEM)
PEM results from inadequate intake of proteins and calories. It is common in children and affects growth and immunity.
Types:
Kwashiorkor: Protein deficiency with adequate calorie intake.
Poverty and food insecurity: Limited access to nutritious food.
4. Diagnosis and Management
A. Diagnosis
Clinical examination: Symptoms like pale skin, stunted growth.
Blood tests: Hemoglobin (for anemia), Vitamin D levels, thyroid function.
Dietary history: Evaluating food intake.
Imaging: Bone density scans for osteoporosis.
B. Management & Prevention
Balanced Diet: Include all food groups.
Supplementation: Multivitamins, iron, calcium.
Fortified Foods: Iodized salt, fortified cereals.
Public Health Programs:
Midday meal scheme
Vitamin A supplementation programs
Iron and folic acid supplementation for pregnant women.
Protein Energy Malnutrition (PEM).
1. Introduction
Protein Energy Malnutrition (PEM) is a condition caused by a deficiency of proteins and calories in the diet. It primarily affects children in developing countries but can also occur in adults with chronic illnesses or severe malnutrition.
2. Magnitude of the Problem
Global Burden
WHO estimates: Around 45 million children under 5 years suffer from wasting (severe acute malnutrition).
PEM contributes to ~45% of all child deaths globally.
Malnourished children have a 9–10 times higher risk of mortality from infections.
Highest prevalence in: South Asia, Sub-Saharan Africa, and low-income countries.
Indian Scenario
NFHS-5 (2020-21) Data:
Stunting (low height for age): 35.5%
Wasting (low weight for height): 19.3%
Underweight (low weight for age): 32.1%
States with High PEM Prevalence: Bihar, Jharkhand, Madhya Pradesh, Uttar Pradesh.
3. Causes of PEM
A. Primary Causes (Inadequate Intake)
Poverty: Low socioeconomic status limits access to nutritious food.
Poor maternal nutrition: Leads to low birth weight and stunted growth.
Improper weaning practices: Early or late introduction of complementary feeding.
Large family size: Divided food resources lead to malnutrition.
Food insecurity: Unavailability of sufficient food.
Severe Acute Malnutrition (SAM) is a life-threatening condition caused by extreme deficiency of calories and proteins. It primarily affects children under 5 years of age and is a major contributor to child morbidity and mortality worldwide.
Global prevalence: ~45 million children suffer from wasting (WHO, 2023).
High-risk regions: South Asia, Sub-Saharan Africa.
Kwashiorkor is a form of severe acute malnutrition (SAM) caused by severe protein deficiency despite an adequate calorie intake. It primarily affects children aged 1-3 years in developing countries and is characterized by edema, skin changes, and a swollen belly. The term “Kwashiorkor” originates from Ghana and means “the disease the first child gets when the second child is born,” as it often occurs when a child is weaned off breast milk too early.
2. Magnitude of the Problem
Global Burden
Approximately 45 million children under 5 years suffer from wasting (acute malnutrition) globally.
Kwashiorkor prevalence: Most common in Africa, South Asia, and Southeast Asia.
Contributes to 50% of childhood deaths related to malnutrition.
Indian Scenario (NFHS-5, 2020-21)
Wasting (low weight for height): 19.3%
Severe wasting (SAM, including Kwashiorkor): 7.7%
Stunting (low height for age): 35.5%
Underweight (low weight for age): 32.1%
High prevalence in: Bihar, Jharkhand, Madhya Pradesh, Uttar Pradesh.
3. Causes of Kwashiorkor
A. Primary Causes (Nutritional Deficiencies)
Lack of protein-rich foods (meat, eggs, dairy, legumes).
Premature weaning (replacing breast milk with starchy foods).
Food insecurity due to poverty and famine.
Unbalanced diet (high in carbohydrates, low in proteins).
Monitor for refeeding syndrome (electrolyte shifts).

Marasmus.
1. Introduction
Marasmus is a severe form of protein-energy malnutrition (PEM) caused by deficiency of both calories and proteins. It primarily affects children under 5 years of age and is characterized by extreme weight loss, muscle wasting, and weakness. Unlike Kwashiorkor, edema is absent in Marasmus.
High-risk group: Infants (6 months – 2 years)
Common in: Developing countries with food insecurity
Mortality risk: Very high if untreated
2. Magnitude of the Problem
Global Prevalence
45 million children under 5 suffer from wasting (WHO, 2023).
Marasmus is more common than Kwashiorkor in famine-affected regions.
High mortality risk if untreated, mainly due to infections.

2. Causes of Vitamin A Deficiency
Vitamin A deficiency occurs due to inadequate intake, poor absorption, or increased demand.
A. Primary Causes (Dietary Deficiency)
✅ Inadequate dietary intake:
Lack of Vitamin A-rich foods (e.g., liver, fish, dairy, green leafy vegetables, orange-colored fruits).
Common in low-income populations relying on cereal-based diets.
✅ Premature Weaning & Poor Infant Feeding:
Lack of breast milk, which is a natural source of Vitamin A.
Early introduction of low-nutrient complementary foods.
Since Vitamin A is stored in the liver, conditions like cirrhosis, hepatitis reduce Vitamin A storage.
✅ Chronic Infections & Increased Demand:
Measles, tuberculosis, HIV/AIDS increase Vitamin A requirements.
Pregnancy & lactation demand higher Vitamin A intake.
3. Signs & Symptoms of Vitamin A Deficiency

B. General Systemic Symptoms
✅ Impaired Immunity – Increased risk of respiratory infections, diarrhea, measles. ✅ Skin Problems – Dry, scaly, and rough skin (Follicular hyperkeratosis). ✅ Growth Retardation – Stunted growth in children. ✅ Anemia – Reduced iron metabolism leading to iron-deficiency anemia. ✅ Reproductive Issues – Infertility & pregnancy complications.
4. Diagnosis of Vitamin A Deficiency

Iron deficiency occurs due to insufficient intake, poor absorption, increased demand, or excessive loss.
A. Primary Causes (Dietary Deficiency)
✅ Inadequate intake of iron-rich foods:
Lack of red meat, poultry, fish, leafy greens, fortified grains. ✅ Vegetarian/Vegan diets:
Plant-based iron (non-heme iron) has lower absorption than animal-based iron (heme iron). ✅ Frequent consumption of tea/coffee:
Inhibits iron absorption due to tannins and polyphenols.
B. Secondary Causes (Increased Demand & Excessive Losses)
Bariatric surgery or chronic diarrhea reduces iron absorption.
✅ Increased Iron Requirement:
Pregnancy & lactation (fetal development and maternal blood expansion).
Rapid growth in infants, children, and adolescents.
3. Signs & Symptoms of Iron Deficiency
Iron deficiency progresses in stages, leading to mild, moderate, or severe anemia.
