Marasmus represents a severe deficiency of both total calories and protein. The body utilizes its own structural tissues to survive.
Medical professionals use several anthropometric systems to classify PEM based on weight, height, and age. Gomez Classification (Based on Weight-for-Age) Calculated as:
┌───────────────────────┐ │ Etiology of PEM │ └───────────┬───────────┘ │ ┌────────────────────────┴────────────────────────┐ ▼ ▼ ┌─────────────────────────┐ ┌─────────────────────────┐ │ Socioeconomic │ │ Clinical/Secondary │ │ (Primary Causes) │ │ (Secondary Causes) │ └────────────┬────────────┘ └────────────┬────────────┘ ├─ Poverty & Food Insecurity ├─ Malabsorption (e.g., IBD) ├─ Over-Diluted Infant Formula ├─ Hypermetabolism (e.g., Cancer) └─ Famine & Political Instability └─ Recurrent Pediatric Infections Socioeconomic and Environmental Drivers
This comparison is the core of any PEM presentation. Use a side-by-side comparative layout to contrast these two distinct clinical manifestations. Nutritional Marasmus (Balanced Starvation) Protein Energy Malnutrition Ppt
This comprehensive guide is structured to serve as an authoritative textual breakdown for medical professionals, educators, and students designing academic presentations or searching for structured clinical summaries. 1. Introduction and Core Definitions
Hypoglycemia and electrolyte imbalances (hypokalemia, hypomagnesemia).
“But we eat every day,” said Asha’s mother, pulling at her sari. “We have cassava and rice and the fish when the river is generous. Why do our children weaken?” Marasmus represents a severe deficiency of both total
Poverty, food insecurity, and lack of nutritional knowledge.
Eradicating PEM requires multi-sectoral interventions addressing the root socioeconomic and educational causes.
Protein-Energy Malnutrition (PEM) remains a critical global health challenge, primarily affecting infants and young children in developing nations. When designing a clinical or academic presentation on this topic, structuring the content logically is essential for maximum audience engagement and retention. and signs of vitamin deficiencies (e.g.
Checking for bilateral pitting edema, skin lesions, and signs of vitamin deficiencies (e.g., vitamin A deficiency/xerophthalmia).
Immune system atrophy (particularly T-cell function) leaves the body highly vulnerable to opportunistic pathogens.
