Children with kwashiorkor were found to have profoundly low levels of albumin and, as a result, became intravascularly depleted. Subsequently, antidiuretic hormone (ADH) increases in response to hypovolemia, resulting in edema. Plasma renin also responds aggressively, causing sodium retention.
What is the pathophysiology of protein energy malnutrition?
Protein-energy malnutrition represents a shift of the body from fed to fasting/starvation state. Starvation leads to a decreased basal plasma insulin concentration and in decrease of glucose-stimulated insulin secretion. Prolonged fasting results in a deficiency in amino acids used for gluconeogenesis.
What is pathophysiology of malnutrition?
It results from the body’s physiologic adaptive response to starvation in response to severe deprivation of energy and all nutrients, and is characterized by wasting of body tissues, particularly muscles and subcutaneous fat, and is usually a result of severe restrictions in energy intake.
What is kwashiorkor and marasmus?
Kwashiorkor, a severe protein deficiency, causes fluid retention and a protruding abdomen. On the other hand, the condition marasmus, which results from severe calorie deficiency, leads to wasting and significant fat and muscle loss (5). Undernutrition can also result in micronutrient deficiencies.
What are the clinical features of marasmus?
Loss of body weight and muscles are the main symptoms of Marasmus. This leads to an extremely low body mass index (BMI). Other symptoms include dizziness, energy loss, brittle hair, and dry skin.
What are the 4 types of malnutrition?
There are 4 broad sub-forms of undernutrition: wasting, stunting, underweight, and deficiencies in vitamins and minerals. Undernutrition makes children in particular much more vulnerable to disease and death.
What are the five causes of malnutrition?
Multiple factors including land and crop degradation, periodic droughts and weather-related shocks, poverty, limited access to basic food staples and essential services, and population growth, contribute to emergency levels of malnutrition in the region.
What is pathophysiology of a disease?
Definition of pathophysiology
: the physiology of abnormal states specifically : the functional changes that accompany a particular syndrome or disease.
What is full form PEM?
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”.[1] It is a major public health problem in India.
What is PEM and its types?
Protein-energy malnutrition (PEM) is classically described as 1 of 2 syndromes, marasmus and kwashiorkor, depending on the presence or absence of edema. Each type may be classified as acute or chronic. Additionally, marasmus can precede kwashiorkor. Many patients exhibit symptoms of both disease states.
