Our nutrition and dietetics service has a number of specialist teams.

    Our community dietitians work with adult patients in Lambeth and Southwark, services include:

    Our specialist dietitians provide support to adult patients who are under-nourished and requiring support.

    This includes patients who are malnourished or at risk of malnutrition, those with pressure ulcers and patients requiring nutritional support due to illness, long-term conditions or social factors.

    We work closely with members of the health and social care teams, and the voluntary sector to ensure malnourished patients receive the appropriate care and support in the community.

    We visit housebound patients at their home and also visit care homes and intermediate care centres.

    General Practice dietitian clinics

    Our dietitians provide a number of clinics in GP practices across Lambeth and Southwark.

    These clinics see patients who are malnourished, prescribed nutritional supplement drinks or seek dietetic advice relating to weight reduction, diabetes or other diet related concerns may be seen in these clinics.
