Loss of appetite
Lung cancer patients usually suffer from loss of appetite due to the changes in taste, nausea, or chronic pain. The patients with lung cancer start eating less than the average amounts of food and lead to the eating disorder of anorexia, which ultimately causes weight loss. The blocking of the airways and the fluid accumulation in the chest cavity makes the lung cancer patients to eat less or not eat at all. The loss of appetite in lung cancer patients is medically known as cancer cachexia, which leads to muscle wasting and unintentional muscle wasting.
