What Are the Signs of Malnutrition in Seniors?

January 13, 2026

Malnutrition is common among older adults and can lead to serious health issues if ignored. Knowing the signs of malnutrition in seniors helps families act early.


Common warning signs include:


  • Unintentional weight loss or loose-fitting clothes
  • Low energy or constant fatigue
  • Muscle weakness or reduced mobility
  • Loss of appetite or skipping meals
  • Dry skin, brittle hair, or hair loss
  • Slow wound healing and frequent illness
  • Confusion or trouble concentrating


Malnutrition may be caused by dental problems, medication side effects, difficulty swallowing, limited mobility, or chronic illness. Emotional factors like depression or isolation can also reduce appetite.


If these symptoms appear, a healthcare provider should evaluate nutritional needs. Early intervention can improve strength, immunity, and overall quality of life.


At The Cottage at Litchfield Hills, residents receive balanced meals and daily support to help ensure proper nutrition and overall well-being.
