Malnutrition

“Malnutrition can be defined as a state of nutrition in which a deficiency or excess (or imbalance) of energy, protein and other nutrients causes measurable adverse effects on tissue/body form (body shape, size, composition), body function and clinical outcome.” (British Dietetic Association, 2019. Manual of Dietetic Practice, 6th Edition)

Malnutrition is not just weight loss — although unplanned weight loss is a common sign. It can also involve:

  • Loss of muscle strength

  • Low energy or fatigue

  • Poor wound healing

  • Increased risk of infection

  • Reduced ability to recover from illness

Why Malnutrition Happens

Malnutrition can develop for many reasons, including:

  • Poor appetite due to illness, medication, or treatment side effects

  • Conditions such as dementia or swallowing difficulties that make eating and drinking harder

  • Reduced mobility or independence, limiting ability to shop, cook, or eat

  • Practical and financial barriers, such as the cost of food or living alone

Why It Matters

Whatever the cause, malnutrition can significantly affect your energy, recovery, and quality of life — but with the right dietetic support, it can often be prevented or improved.

What to Expect in Your Assessment

During your session, your dietitian will:

  • Explore your current situation – reviewing recent weight changes, appetite, lifestyle factors, and relevant medical history.

  • Work out your nutritional requirements – estimating your energy, protein, and nutrient needs based on age, weight, health, and activity level.

  • Identify any deficits or risks – highlighting where your current intake may not be meeting your nutritional needs.

  • Review your current intake – discussing your usual eating and drinking patterns and any barriers or challenges.

  • Provide food fortification strategies – showing you how to add extra calories and protein to meals and snacks you already enjoy, with practical, affordable examples.

  • Make recommendations to your GP (if appropriate) – providing a written summary if prescription nutrition support products or further medical input may be beneficial.

  • Agree a personalised plan – creating clear, realistic steps to support weight stability, strength, recovery, and overall quality of life.

Your plan will be individualised and, where relevant, can be shared with your wider healthcare team for continuity of care.
