Changes in eating often occur when you have cancer or during cancer treatment. No appetite or loss of appetite, no hunger or slow hunger, inability to eat or bloating with little food are common phenomena. Persistent anorexia will lead to weight loss, wasting, weakness and reduced resistance, which in severe cases directly affects the quality of life, accelerates disease progression and also affects the effectiveness of treatment. Anorexia is the most common problem for doctors and family members. Then, how can we overcome anorexia in cancer patients? Of course, the first step is to understand the causes of anorexia. The causes of anorexia are complex, and the common ones are: 1. Factors of cancer itself. For example, cancer-related metabolic abnormality or metabolic alteration produced multiple anorexic factors, such as IL-6, tumor necrosis factor, etc. Therefore, many cancers show anorexia and wasting very early before diagnosis, improve after effective treatment, and reappear at recurrence. In addition, some symptoms of tumors, such as ascites or occupying abdominal tumors, are also common causes of abdominal distention and early satiety. 2. Factors related to cancer treatment. Surgery related to digestive tract, chemotherapy, radiotherapy and immunotherapy can cause temporary loss of appetite. Radiotherapy can also cause abnormalities in taste and smell and changes in taste, which can lead to refusal to eat due to aversion to the smell or taste of food. Taking sedatives will also make you not think about eating. 3. Various causes of mouth ulcers, painful eating, difficulty in swallowing and chewing, causing fear of eating. 4.Nausea, vomiting, constipation, pressure on the digestive tract or difficulty in peristaltic emptying, resulting in no appetite and abdominal distension tolerance after eating. 5.Concomitant diseases, such as depression, pain and fatigue, likewise cause anorexia or lack of appetite. Undoubtedly, the first priority in treating anorexia in cancer patients is to control the cancer as much as possible. Once the tumor is well controlled, appetite will generally improve significantly or enhance significantly. Secondly, the cause of discomfort after eating should be relieved as much as possible. For example, treat mouth ulcers and dry mouth, gargle with anesthetic before eating to temporarily relieve the pain after eating and avoid eating phobia. Keep the digestive tract open, take gastrointestinal motility promoters such as morpholine and mosapride; eliminate constipation, use laxative and laxative drugs; if caused by intra-abdominal ascites or mass compression or occupancy, consider medical interventions to release ascites and rapidly shrink the mass. Increase appetite and use appetite enhancers if necessary, e.g., megestrol, androgens, etc. If accompanied by depression, treatment of depression will often improve appetite. While the above are more medical interventions that require the help of a doctor, the following are some that may be more convenient for patients and families to use directly. First, be “proactive” about eating. The importance of eating and taking in nutrients needs to be understood. It is as important, if not more important, to eat as it is to take medication to treat illness. Getting adequate nutrition and maintaining weight is essential to maintaining vitality and health, and while nutrition can be obtained by intravenous infusion, eating is always an irreplaceable alternative in terms of safety, effectiveness and economy. So it is important to remember that whether you like it or not, and whether it tastes good or not, you must eat in order to recover! Secondly, eat “strategically”. 1, hungry need to eat! Only three meals is not enough, can be 5 to 6 times a day or more (including snacks). 2, hungry to eat immediately. Pay attention to the time of day usually hungry, prepare food in advance, so that when you are hungry, do not wait, not limited. 3, the main meal should eat well. Food should be added to high protein and high calorie ingredients, can be seasoned. Such as: broth, butter, cheese, peanut butter, etc. 6, meals without soup (drinks). Can drink between meals, otherwise easy to fill up. Beverage choice nutritional type, such as milk, or milkshake. 7, eat cold not hot. The temperature of the food, choose cold food or room temperature food, the purpose is to reduce the smell and reduce the taste of food emitted. If you eat tasteless, you can adjust the color of the food, try to add food seasoning or spices to make the food more tempting. 4, snacks can not be missing. Always have your favorite snacks on hand. 5, snacks have requirements. Prepare high-calorie, high-protein snacks. For example, dried fruit, nuts, yogurt, cheese, eggs, milkshakes, ice cream, cereal, etc. 8. Do not overwork before meals. Do not cook your own meals when you are tired, by family members, or choose a semi-prepared in advance. To avoid the meal is ready, people do not want to eat. 9, dining with mood. Elegant environment, beautiful music, accompanied by family or friends to eat together. 10, before the meal should exercise. One hour before the meal low intensity exercise, such as 20 minutes walking, may stimulate your appetite.
