By Indra Balaratnam PROPER nutrition is important for health and wellbeing. This is especially so when you are recovering from surgery. The process of surgery can be very draining on the body. Many patients I see (after surgery) experience a loss of weight for several reasons - namely muscle wastage, lack of appetite, and dehydration. This type of weight loss can negatively affect the quality of life by prolonging healing and recovery. This in turn leaves the patient susceptible to developing post-surgery complications. Once they have left the hospital and returned home, many patients are anxious about their recovery. Even their family members have lots of questions to ask about what are the best foods they can prepare and give to their family member who has just had surgery. The nutrition goal for a person recovering from surgery is to ensure they eat sufficient calories and protein by having balanced meals. After undergoing surgery, it would be beneficial for you to seek the help of a qualified dietitian to help assess and make recommendations for meal planning. Ask your doctor or surgeon to refer you to see a dietitian. The main goals for a patient during this post-surgery time are: To prevent or replenish nutrient deficiencies To preserve lean muscle mass and muscle To protect the patient's immune function to reduce the risk of secondary infection More importantly, the main purpose of good nutrition is to maximise quality of life. Your illness and subsequent surgery may have struck you a blow, but now it's time to fight back. Here are some practical tips to help you do this.
