Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form. [13] Malnutrition is a category of diseases that includes undernutrition and ...
Marasmus. Marasmus is a form of severe malnutrition characterized by energy deficiency. It can occur in anyone with severe malnutrition but usually occurs in children. Body weight is reduced to less than 62% of the normal (expected) body weight for the age. [1] Marasmus occurrence increases prior to age 1, whereas kwashiorkor occurrence ...
Kwashiorkor (protein malnutrition predominant) Marasmus (deficiency in calorie intake) Marasmic kwashiorkor (marked protein deficiency and marked calorie insufficiency signs present, sometimes referred to as the most severe form of malnutrition) PEU is fairly common worldwide in both children and adults and accounts for about 250,000 deaths ...
Kwashiorkor is a type of severe acute malnutrition (SAM). SAM is a category, composed of two conditions: marasmus and kwashiorkor. [9] Both kwashiorkor and marasmus fall under the umbrella of protein–energy malnutrition (PEM). [10] These diseases are oftentimes discussed together, but are distinctly separate conditions of malnutrition.
Malnutrition in older adults is a significant health concern, linked to increased mortality, morbidity, and physical decline, which adversely impacts daily activities and overall quality of life. This condition is common among the elderly and can also contribute to the development of geriatric syndromes. [ 164 ]
Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition. In humans, prolonged starvation can cause permanent organ damage [ 1 ] and eventually, death. The term inanition[ 2 ] refers to the symptoms and effects of starvation.
Some signs and symptoms of malnutrition in older adults may include: unintended weight loss, tiredness and fatigue, muscle weakness or loss of strength, constipation, dizziness, syncope, gastritis, peptic ulcers, paleness of the skin, poor wound healing, depression, problems with memory, a weak immune system, and anemia.
Malnutrition can also be classified to acute malnutrition and chronic malnutrition. Acute malnutrition indicates inadequate or insufficient nutrient intake resulting in severe systemic degeneration. Globally, approximately 32.7 million children under 5 years are found to have visible and clinical signs of acute malnutrition.
