Lung cancer is one of the most common types of cancer globally, including genetic, environmental and lifestyle factors. Cancer treatment can be challenging to treat and can be a barrier in front of a healthy patient’s nutritional diet. It is important to take care of the nutritional factors such as diet, alcohol intake, body weight and regular physical activity. Some common symptoms that a patient experiences during lung cancer treatment are fatigue, pain, loss of appetite, nausea, vomiting and swallowing difficulties. All these signs can hinder the process of food intake. When the food intake is not adequate, there is a higher risk of suffering from malnutrition.
A lot of patients who have lung cancer drop their weight during treatment, however, more than 10% of the usual body weight along with major loss of muscle mass. If a patient goes through cancer treatment including surgery, chemotherapy, targeted therapy, immunotherapy and radiation therapy, the body goes towards positive healing. The course of treatment requires certain nutrients, more calories and good amounts of protein. Onlymyhealth editorial team spoke to Dr. Esther Sathiaraj, Head- Clinical Nutrition and Dietetics, HCG Cancer Hospital Bengaluru, about the diet to consume during lung cancer treatment.

Having a good amount of calorie intake in your diet to meet the nutritional requirements would help in maintaining a healthy body weight. It is important to create your meals calorie-dense by including milk or cream or coconut milk to gravies, snack on nuts and dried fruits, eat larger meals when your appetite is good and eat small meals and snacks through the day. A small gap meal pattern with healthy soups, fruit juices, fruit milkshakes, smoothies and yogurts taken between intervals of huge meals is suggested. You can talk to your nutritionist to understand the different foods and ways to include them in your daily diet.

Dealing with lung cancer
Sometimes, the immunity of the patients gets weak, mostly depending on the type of cancer treatment. In some cases, the white blood cell numbers get affected leading to a higher potential risk for foodborne infections. The side effects of cancer treatment are based on the patient and thus there is no need to modify or customize your diet completely if you are not having any side effects of low appetite, fatigue, and nausea. You need to aim on healthy eating and a balanced, nutritious diet with many proteins, fruits, vegetables, and whole grains. A number of patients are usually stressed and depressed while going through cancer treatment. It is suggested by experts to regularly update the doctor about the health conditions.
