What is a common cause of dyspnea in palliative care patients?

In palliative care, a common cause of dyspnea, or difficulty breathing, is respiratory diseases and conditions. Many patients in palliative care have advanced illnesses such as chronic obstructive pulmonary disease (COPD), pneumonia, lung cancer, or heart failure, all of which can significantly impact respiratory function. The physiological changes and progression of these diseases lead to increased shortness of breath, which can be distressing for patients.

While anxiety and stress, medication side effects, and unresolved emotional issues can contribute to the experience of dyspnea or amplify the perception of breathlessness, the primary underlying cause in many palliative care contexts tends to be related to actual physiological changes in the respiratory system due to disease. Understanding the root causes of dyspnea is crucial in palliative care, as it allows for more effective management strategies, including pharmacological interventions and supportive therapies that target the specific underlying conditions affecting the patient's ability to breathe comfortably.
