Red flags / send to ED#

• Acute decompensation (altered mental status, severe dehydration, hemodynamic instability) → ED
• Severe malnutrition with electrolyte abnormalities → ED
• Suspected elder abuse or neglect → ED; involve social work and APS
• Suicidal ideation → ED for psychiatric evaluation
• Acute abdomen or GI obstruction → ED

Urgent (expedited outpatient):

• Rapid weight loss (>5% in 1 month or >10% in 6 months)
• New dysphagia
• Suspected malignancy
• Severe depression with poor intake
• Unsafe living situation

Key history#

Define the decline:

• Weight loss: How much? Over what time period?
  • Significant: >5% in 1 month, >7.5% in 3 months, >10% in 6 months
• Functional decline: What could they do before that they can’t do now?
• Timeline: When did family/patient first notice changes?
• Trajectory: Gradual decline vs stepwise vs rapid

The 9 D’s of failure to thrive:

1. Dementia: Forgetting to eat; unable to prepare food; not recognizing hunger
2. Depression: Loss of appetite; “don’t care”; anhedonia; hopelessness
3. Disease (chronic): Cancer, COPD, HF, CKD, liver disease
4. Dysphagia: Difficulty swallowing; choking; food avoidance
5. Dysgeusia: Altered taste (medications, zinc deficiency, illness)
6. Diarrhea/malabsorption: Chronic diarrhea; steatorrhea
7. Drugs: Medications causing anorexia, nausea, altered taste
8. Dentition: Poor teeth; ill-fitting dentures; oral pain
9. Destitution: Poverty; food insecurity; social isolation

Nutritional assessment:

• What do you eat in a typical day? (24-hour recall)
• Who prepares meals?
• Do you eat alone?
• Any difficulty chewing or swallowing?
• Any foods you avoid? Why?
• Appetite: Good, fair, poor?
• Early satiety?
• Nausea, vomiting?
• Changes in taste or smell?
• Dentures: Do they fit? Do you wear them?

Functional assessment:

• ADLs: Bathing, dressing, toileting, transferring, eating
• IADLs: Cooking, shopping, managing finances, medications, transportation
• Mobility: Walking, stairs, falls
• What has changed recently?

Psychosocial assessment:

Differential (quick pattern recognition)#

Common/likely (outpatient)#

Can’t-miss / urgent#

Workup#

Initial workup:

Second-tier testing (based on clinical suspicion):

When NOT to order extensive workup:

• Clear cause identified (depression, medication, social factors)
• Patient with known terminal illness and expected decline
• Patient/family decline further workup (goals of care)
• Very frail patient where results won’t change management

Approach to unexplained weight loss:

1. Thorough history and exam (often reveals cause)
2. Basic labs (CBC, CMP, TSH, UA)
3. Age-appropriate cancer screening if not current
4. If still unexplained: CT chest/abdomen/pelvis
5. If CT negative and weight loss continues: Close follow-up; repeat workup in 3-6 months

Initial management#

Priorities:

1. Identify and treat reversible causes
2. Optimize nutrition
3. Address psychosocial factors
4. Align care with goals and prognosis
5. Prevent further decline

Nutritional interventions:

Address barriers:

• Dental problems → Dental referral; soft diet
• Dysphagia → Speech therapy; modified diet texture
• Depression → Treat depression
• Medications → Adjust/stop offending medications
• Social isolation → Meals on Wheels; senior center; family involvement
• Food insecurity → SNAP; food bank; social work
• Cognitive impairment → Supervision; cueing; assistance with meals

Appetite stimulants (limited evidence; use judiciously):

Caution: Appetite stimulants have limited evidence for improving outcomes in geriatric failure to thrive. Focus on treating underlying causes and optimizing nutrition first.

Management by diagnosis#

Depression-related failure to thrive#

Education:

• Depression is very common in older adults and can cause weight loss and decline
• Treatment can significantly improve appetite, energy, and quality of life
• It may take a few weeks to see improvement

Treatment:

Non-pharmacologic:

• Psychotherapy (if cognitively able)
• Social engagement
• Exercise (if able)
• Address grief and losses
• Involve family/caregivers

Follow-up: 2-4 weeks to assess response; adjust treatment as needed.

Dementia-related nutritional decline#

Education:

• People with dementia often forget to eat or lose interest in food
• Supervision and assistance with meals can help
• As dementia progresses, eating difficulties are expected

Management:

• Supervision and cueing at meals
• Finger foods (easier to eat independently)
• One food at a time (reduce confusion)
• Adequate time for meals (don’t rush)
• Pleasant, calm environment
• Consistent mealtime routine
• High-calorie, nutrient-dense foods
• Oral supplements between meals
• Treat pain, constipation, depression

Advanced dementia considerations:

• Feeding tubes do NOT improve outcomes in advanced dementia
• Hand feeding is preferred
• Comfort-focused care
• Goals of care discussion with family

Follow-up: Regular monitoring; adjust care as dementia progresses.

Dysphagia#

Education:

• Difficulty swallowing can lead to weight loss and aspiration pneumonia
• A swallowing evaluation can help determine the safest diet
• Modifying food texture and eating techniques can help

Management:

• Speech therapy referral for swallow evaluation
• Modified diet texture (pureed, mechanical soft, thickened liquids) per SLP recommendations
• Swallowing strategies (chin tuck, small bites, etc.)
• Upright positioning during and after meals
• Treat underlying cause if possible (stroke rehab, Parkinson’s optimization)

Referral: Speech therapy; GI if structural cause suspected.

Follow-up: After SLP evaluation; monitor for aspiration, weight.

Social isolation and food insecurity#

Education:

• Eating alone and not having access to food are common problems that we can help with
• There are programs and resources available

Resources:

• Meals on Wheels: Home-delivered meals
• Senior centers: Congregate meals and socialization
• SNAP (food stamps): Supplemental Nutrition Assistance Program
• Food banks and pantries
• Area Agency on Aging: Local resources
• Social work referral: Help navigating resources

Management:

• Social work consultation
• Connect with community resources
• Encourage family involvement
• Consider adult day programs
• Address transportation barriers

Follow-up: 2-4 weeks to ensure resources connected; monitor weight.

End-stage disease / Palliative approach#

Education:

• When serious illness progresses, the body naturally loses appetite and weight
• Forcing food doesn’t help and can cause discomfort
• Our focus shifts to comfort and quality of life

Management:

• Goals of care discussion
• Palliative care referral
• Comfort-focused nutrition:
  • Offer favorite foods in small amounts
  • Don’t force eating
  • Good mouth care
  • Treat symptoms (pain, nausea, dry mouth)
• Hospice referral when appropriate
• Family support and education

What NOT to do:

• Don’t place feeding tubes in end-stage dementia (no benefit, causes harm)
• Don’t force nutrition when body is shutting down
• Don’t make patient feel guilty about not eating

Follow-up: Regular contact for symptom management and family support.

Follow-up#

Initial follow-up:

• 2-4 weeks after interventions started
• Sooner if rapid decline or acute issues

What to reassess:

• Weight (compare to baseline)
• Functional status
• Nutritional intake (24-hour recall)
• Mood
• Response to treatment of underlying cause
• Social situation
• Caregiver status

Monitoring:

• Weight at every visit
• Albumin/prealbumin if severe malnutrition (every 1-3 months)
• Functional status assessment

When to escalate:

• Continued weight loss despite interventions
• New symptoms suggesting undiagnosed cause
• Functional decline
• Caregiver burnout
• Safety concerns

Prognosis discussion:

• Failure to thrive in elderly is associated with increased mortality
• Honest discussion about trajectory
• Align care with patient goals
• Consider palliative care or hospice when appropriate

Patient instructions#

For patient and family/caregiver:

• We’re concerned about your weight loss and want to help you feel stronger.
• Eating well is important, but we know it can be hard when you don’t feel hungry. Here are some tips:
  • Eat small amounts frequently—5-6 small meals or snacks instead of 3 big meals.
  • Choose foods you enjoy, even if they’re not “healthy.” Calories and protein matter most right now.
  • Add extra calories: butter, cream, cheese, peanut butter, olive oil.
  • Try nutritional drinks like Ensure or Boost between meals.
  • Eat with others when possible—meals are more enjoyable with company.
• If chewing or swallowing is hard, let us know. We can help with that.
• If you’re feeling sad, hopeless, or don’t care about eating, please tell us. Depression is treatable.
• If cost or getting food is a problem, we can connect you with resources.
• Take your medications as prescribed, but let us know if any make you feel sick or lose your appetite.
• Call us if you’re losing more weight, can’t keep food down, feel very weak, or have any new symptoms.
