Failure-to-Thrive—Adult

Definition

Failure-to-thrive is a decrease in mental and physical ability.

Causes

Failure-to-thrive is caused by more than one problem. It is not the same for each person. Long term health problems often play a role.

For example, mental health problems can make it hard for some people to eat well. This can worsen health.

Risk Factors

Failure-to-thrive is more common in older adults. Other things that may raise the risk are:

  • Having more than one long term health problem
  • Taking certain medicines
  • Physical or intellectual limits
  • Having little or no social interaction
  • Limited income

Symptoms

Symptoms may be:

  • Lack of hunger
  • Confusion
  • Losing weight without trying
  • Less activity
  • Being more tired than usual
  • Feelings of depression

Diagnosis

The doctor will ask about symptoms, past health, diet, and activities. A physical and mental health exam will be done.

Tests may be done to look for physical causes. It may take some time to find all the issues that are causing the problem.

Treatment

Treatment will depend on the causes. Options may be:

Treating Current Health Problems

Changes may need to be made to manage long term health problems. Sometimes a treatment can cause problems and may need to be changed.

Diet Changes

A dietitian can help with meal planning and food choices.

Supportive Therapy

Supportive care may be:

  • Social workers who can suggest services—to help with shopping, meals, and home care
  • Physical or occupational therapy—to help with movement
  • Counseling—to talk about emotions

Medications

Medicine may be given for depression.

End-of-Life Care

Failure-to-thrive may be the end stage of an illness. Advance directives are important for a care plan. These documents can help guide a person's medical care. It is for people who cannot direct their own care. Other important documents are a living will and medical power of attorney.

Prevention

To help prevent failure to thrive:

  • Get medical help for problems
  • Follow a care plan for a long term health problem
