Undernutrition (how to gain weight)

The Community Dietetics Team promote the use of food and drink as treatment for people who are identified as moderate and high risk of undernutrition. However, sometimes despite best efforts it is not always possible to meet nutritional requirements from food alone and prescribed nutritional supplements may need to be considered.

If there are any concerns about weight loss or poor appetite it is important that advice is sought from a healthcare professional, such as a GP or a dietitian.

Every mouthful counts if someone has a poor appetite. It is therefore very important that food and drinks are packed full of nourishment. This means that even though only small portion sizes are eaten, nutritional requirements may still be met, preventing further weight loss prevented and promoting weight gain.

1. Nourishing snacks

Nourishing snacks are recommended at least twice a day. Nourishing snack ideas are slice of malt loaf, cheese and biscuits, half a scone or teacake, handful of nuts, piece of cake. A plain biscuit e.g. rich tea, morning coffee, is not a nourishing snack as it is low in calories. One slice of malt loaf is the same amount calories as four plain biscuits

2. Nourishing drink

Nourishing drinks are encouraged throughout the dayReplace at least two cups of tea or other lower calorie drinks with nourishing drinksNourishing drinks ideas are milky coffee, milky hot chocolate, fruit juiceDid you know a cup of milky coffee made with full cream milk is the same amount of calories as eight cup of teas

3. Fortified diet (high calorie protein diet)

A fortified diet is where meal dishes are adapted by adding small quantities of everyday foods which increases the calorie and nutrient content without increasing the portion size. This means every mouthful is full of nourishment

4. Multivitamin and mineral capsules

It is recommended that a general multivitamin and mineral capsule is taken daily, to ensure adequate amounts of micronutrients. A version from the chemist should be suitable

Seek advice from a pharmacist or GP to determine an appropriate product.

5. Homemade fortified drinks

Two homemade fortified drinks are recommended each day

• Each 200mls drink contains at least 300 calories which is similar to prescribed nutritional supplement drinks for example Complan Shake, Fortisip, Fortijuce and Ensure Plus
• Homemade fortified drinks are made with full cream milk, skimmed milk powder and other ingredients which are readily available within the home. The drinks can be prepared by the individual, family member or carer
• Fortified drink recipes include: fortified milkshake, fortified soup, fortified smoothies, fortified hot chocolate, fortified malted drinks

Prescribed nutritional supplements have a valuable role in the management of undernutrition when used appropriately.

It is recommended before any nutritional supplement is prescribed:

• the individual is identified as high risk of undernutrition using 'MUST'
• high risk dietary interventions have been trialled for a month but further weight loss has been identified
• prescribe a powdered nutritional supplements as the initial supplement, refer to the nutritional supplement care pathway.

Examples of first line prescribed nutritional supplements include Foodlink Complete, Complan Shake, Aymes Shake, Ensure Shake.

Once prescribed nutritional supplements, a regular review should be completed by a dietitian or an appropriately trained healthcare professional.
