What does failure to thrive mean in adults?

The wording can sound like a diagnosis, but it is a starting description of change. Someone may eat less, lose weight, tire easily, move less, withdraw socially, or need more help with washing, dressing, or shopping. Several issues can overlap: a painful mouth, medicine side effects, loneliness, low mood, infection, chronic disease, or difficulty chewing and swallowing. Finding the pattern and its causes helps guide useful support.

Ask the clinician to explain which changes led to the term and what they want to investigate. Record appetite, fluids, symptoms, medicines, falls, and changes in daily tasks. Offer easy-to-eat meals and company at mealtimes if welcomed. A professional may assess nutrition, mood, mobility, swallowing, oral health, and home safety, then coordinate treatment or practical help.

Get urgent medical help if there is sudden confusion, collapse, severe breathlessness, chest pain, inability to drink, or rapidly worsening weakness. Do not delay a routine appointment when appetite remains low, weight is falling, swallowing is difficult, falls are recurring, or a person is no longer coping with essential activities.

Ask what the term means in this person’s case, which reversible problems will be checked, how to support meals and mobility, and when follow-up should occur.
