Malnutrition means a deficiency, excess, or imbalance in a person's nutrient intake, most commonly discussed in the context of under-nutrition — not getting enough calories, protein, or specific nutrients.
Common symptoms
Unintentional weight loss, fatigue, muscle weakness, slow wound healing, frequent infections, and — in more advanced cases — noticeable loss of muscle and fat.
General self-care measures
- Eat regular, nutritionally balanced meals; a dietitian can help design an appropriate plan for a specific situation.
- Address underlying causes where identifiable (swallowing difficulty, digestive conditions, appetite loss from illness or medication).
- Use nutritional supplements only as recommended by a healthcare professional, since inappropriate supplementation (especially reintroducing food too quickly after severe malnutrition) can be harmful.
- Monitor weight and nutritional status over time, especially for those at higher risk (older adults, people with chronic illness).
When to seek medical attention
- Unintentional weight loss, especially if significant or unexplained.
- Signs of malnutrition in someone with a chronic illness, difficulty eating, or reduced appetite over time.
- Concerns about a child not gaining weight or growing as expected.
- Severe malnutrition — refeeding needs careful medical supervision due to the risk of refeeding syndrome.
Common pitfalls
- Reintroducing food or nutrition too quickly after a period of severe malnutrition — this risks refeeding syndrome, a potentially serious complication; nutritional support after significant malnutrition needs professional guidance on pacing.
- Assuming malnutrition only affects visibly underweight people — it can occur in people of any body size, including those who appear overweight, if their diet lacks essential nutrients.
- Treating unintentional weight loss as automatically positive — unlike planned weight loss, unintentional weight loss (particularly in older adults or those with chronic illness) is often a warning sign worth investigating.
