Study Notes
Malnutrition Overview
- Malnutrition is a cellular imbalance between nutrient/energy supply and the body's demand for these to ensure growth, maintenance, and specific functions (WHO).
- Types of malnutrition include under-nutrition and over-nutrition. Under-nutrition involves insufficient nutrients, and over-nutrition involves excess nutrients. Both can lead to nutritional disorders.
Causes of Malnutrition
- Primary causes:
- Low income/purchasing power
- Scarcity of food supply
- Ignorance/erroneous food habits
- Overpopulation
- Secondary causes:
- Obesity, insulin resistance, and diabetes
- Hepatobiliary disorders
- Metabolic and renal diseases
- Diarrhea and intestinal malabsorption
- Infections (especially respiratory)
Disorders Due to Malnutrition
- Protein-energy malnutrition:
- Kwashiorkor (children 1-3 years old) - characterized by edema and enlarged liver with fatty infiltrates, caused by sufficient calorie intake but insufficient protein.
- Marasmus - severe protein-energy malnutrition, characterized by energy deficiency and emaciation.
- Under-nutrition of vitamins and minerals:
- Calcium deficiency (Rickets)
- Iodine deficiency (Goiter)
- Iron deficiency (Anemia)
- Zinc deficiency (growth retardation)
- Vitamin B1 deficiency (Beriberi)
- Vitamin B3 deficiency (Pellagra)
- Vitamin C deficiency (Scurvy)
- Vitamin D deficiency (Rickets)
Differences Between Kwashiorkor and Marasmus
- Kwashiorkor: Occurs in children 6 months to 3 years. Subcutaneous fat is preserved. Edema, enlarged fatty liver, less prominent ribs. Muscle wasting is mild or absent. Poor appetite. Needs adequate protein.
- Marasmus: Occurs in infants under one year. Subcutaneous fat is not preserved. No edema, no fatty liver, very prominent ribs. Severe muscle wasting. Alert and irritable. Needs adequate protein, fats, and carbohydrates.
Types of Beriberi
- Wet beriberi: Generalized edema, acute cardiac symptoms, prompt response to thiamine administration.
- Dry beriberi: Edema not present, neurological symptoms.
Niacin Deficiency (Pellagra)
- Pellagra is caused by a lack of vitamin B3 (niacin).
- Symptoms include inflamed skin, diarrhea, dementia, and sores in the mouth.
Goiter
- Goiter is a neck swelling from enlarged thyroid gland.
- Commonly due to iodine deficiency or thyroid gland inflammation.
Anemia
- Iron-deficiency anemia is common. Caused by insufficient iron intake/absorption and/or blood loss from various sources (intestinal, uterine, or urinary).
Rickets
- Rickets is softening of bones in immature mammals.
- Due to vitamin D, phosphorus, or calcium deficiency/impaired metabolism.

- Enov/Nutributter: 20g sachet, prevents malnutrition and contributes to healthy child development, for children 6 to 23 months. One sachet per day per child.
- Therapeutic CMV: 800g tin, for reconstitution with other ingredients of F-75 and F-100 therapeutic milk. Children with severe acute malnutrition.
- Appéti'mix: 4kg bucket, high protein, high calorie paste enriched with vitamins and minerals, intended for mass catering to combat undernutrition in the elderly.
