Two obvious signs of malnutrition are increases or decreases in appetite or weight.
Some less obvious warning signs include:
- Dull, dry hair
- Dry eyes
- Receding gums
- Loss of sensation
- Physical weakness
- Bruising easily
- Slow healing of wounds
- Problems with your mouth or teeth
Signs of dehydration (inadequate intake of liquids) include:
- Decreased urination
- Dry mucous membranes (for example, dry mouth)
Researchers have found that people in long-term facilities who regularly leave more than a quarter of their food on the plate at the end of a meal are at high risk of being undernourished.
