If you notice a general lack of energy that doesn’t go away even after you have rested, it can be a sign of PF. Fatigue, both mental and physical is a common complaint from those suffering from pulmonary fibrosis. Fatigue is best described as an unrelenting form of exhaustion that has a negative effect on all aspects of life. Pulmonary fibrosis, being an autoimmune disease has several symptoms, but fatigue is the most debilitating symptom out of all that adversely affects the overall quality of life of the patient.
In PF patients, fatigue may be a result of decreased oxygen intake, lack of sleep due to breathing difficulties and lower amounts of REM sleep. Mental fatigue is also common in those suffering from PF. Most patients suffering from pulmonary fibrosis tend to require more time alone to processes their thoughts, feelings, and emotions even if they were previously very social people.
