Nutritional problems are common across all age groups and can significantly impact health, recovery, and quality of life. Whether caused by illness, reduced appetite, digestive issues, medication side effects, or increased nutritional needs, early identification and management is essential.
This guide provides practical, evidence-based strategies to help patients, carers and healthcare professionals manage common nutritional challenges safely and effectively.
Nutritional problems occur when the body does not receive the right balance of nutrients to function optimally. This may include:
Unintentional weight loss
Poor appetite
Difficulty swallowing (dysphagia)
Nausea or vomiting
Constipation or diarrhoea
Vitamin and mineral deficiencies
Fatigue linked to low intake
Left unmanaged, these issues can lead to weakened immunity, delayed healing, muscle loss, and increased risk of hospital admission.
Nutritional challenges can arise from:
Acute or chronic illness
Cancer treatment
Gastrointestinal disorders
Mental health conditions
Medication side effects
Age-related appetite changes
Social isolation or reduced access to food
Understanding the underlying cause helps guide the most effective intervention.
In many cases, simple dietary adjustments can significantly improve intake:
Eating little and often (small frequent meals)
Fortifying foods with high-energy ingredients (e.g., milk powder, cheese, nut butters)
Choosing nutrient-dense snacks
Adding healthy fats to meals
Prioritising protein at each meal
Establish a routine eating schedule
Focus on favourite foods
Limit fluids before meals
Create a pleasant eating environment
Encourage gentle activity to stimulate hunger
Modify food texture as clinically advised
Ensure upright positioning during meals
Use prescribed thickening agents where required
Work alongside speech and language therapy teams
For nausea:
Small, bland meals
Avoid strong smells
Cold foods may be better tolerated
For constipation:
Gradual fibre increase
Adequate hydration
Gentle physical activity
For diarrhoea:
Monitor hydration closely
Avoid high-fat or spicy foods
Seek medical advice if persistent
Where food alone is insufficient, oral nutritional supplements may be recommended by healthcare professionals. These should be:
Clinically assessed
Monitored regularly
Reviewed for effectiveness
Supplements should complement, not replace, balanced meals unless medically indicated.
