You may find that your appetite will reduce for a spell after surgery. During your stay in hospital, you may be given nutritional supplement drinks to take. These drinks are high in energy and protein and are used to supplement your oral intake following surgery. Your dietitian will assess if these are required on discharge.
It is important you continue to monitor your weight and any symptoms that may affect your appetite, if you are concerned you should contact your specialist nurse who can refer you to the dietitian.
