During cancer treatment, common side effects can include loss of appetite and changes in your sense of smell, taste and food texture which can impact your desire to eat and drink. A dietitian is best placed to help you devise strategies appropriate to your individual situation. These may include smaller, more frequent meals throughout the day, and/or a high energy, high protein diet. If your usual diet is not enough to meet nutritional requirements, a healthcare professional may also recommend a nutrition support solution e.g. oral nutritional supplement like Fortisip Compact Protein.
