About Malnutrition
Malnutrition is a condition caused by poor nutrition, and can manifest as undernutrition, overnutrition, or micronutrient deficiencies.5
Undernutrition
Caused by insufficient intake of energy, protein, or essential nutrients, leading to weight loss. Malnutrition from undernutrition negatively impacts functional status parameters, activities of daily living, muscle mass and strength, frailty, sarcopenia, risk of falls, and immune function.9-14
Overnutrition
Involves excessive caloric intake, often leading to obesity and related metabolic disorders.
Micronutrient deficiencies
Occur when an individual has inadequate intake of essential vitamins and minerals in their diet, potentially resulting in health complications.
Malnutrition exists in both institutional care and the community.6
A large-scale multinational study showed that malnutrition in adults 65 years and older remained high across all care settings:15
Setting | Malnutrition | Risk of Malnutrition |
|---|---|---|
Rehabilitation | 50.5% | 41.2% |
Hospital | 38.7% | 47.3% |
Nursing Home | 13.8% | 53.4% |
Community | 5.8% | 31.9% |

CAUSES AND CONSEQUENCES OF MALNUTRITION
Malnutrition is both a cause and consequence of disease.
CONDITIONS ASSOCIATED WITH MALNUTRITION
Malnutrition is often linked to numerous medical conditions, including:
Chronic diseases
Cancer, diabetes, chronic kidney disease, and inflammatory bowel disease can contribute to malnutrition due to increased metabolic demands or decreased appetite.
Malabsorptive disorders
Conditions like celiac disease, Crohn's disease, and short bowel syndrome hinder nutrient absorption, and may lead to malnutrition.
Eating disorders
Anorexia nervosa, bulimia nervosa, and binge-eating disorder can result in malnutrition and significant health consequences.
Aging Increases Risk of Malnutrition:
Addressing malnutrition requires a holistic approach that considers both the prevention and treatment of malnutrition in diverse settings. Nutritional screening, early intervention, and personalized nutritional support are essential to addressing malnutrition and improving overall health and well-being.21

NUTRITION STRATEGIES FOR TREATING & PREVENTING MALNUTRITION
Nutrition plays a central role in replenishing depleted nutrients, supporting tissue repair, and restoring the overall health of malnourished patients. Adequate nutrition is essential for the body's immune system, energy metabolism, and organ function. In malnourished individuals, nutrient deficiencies can weaken the immune response, impair wound healing, and lead to muscle wasting, making them more susceptible to infections and other health complications.6 Providing the right nutrients in proper quantities is critical to treat malnutrition and promote optimal recovery.
Various nutrition interventions, including nutrition counseling, oral nutritional supplements, vitamin and mineral supplements or enteral nutrition (tube feeding) can be considered in addressing nutrient deficiencies and promoting improved health outcomes for patients at risk or suffering from malnutrition.
Nestlé Health Science's evidence-based nutritional solutions offer a diverse range of options to support healthcare professionals in their efforts to combat malnutrition effectively.
