Many people with pulmonary fibrosis develop obstructive sleep apnoea – a breathing problem that happens when you sleep.
Symptoms at night include snoring, pauses in breathing when asleep, struggling to breathe and tossing and turning.
Daytime symptoms may include waking up sleepy and feeling groggy and less alert, feeling depressed or irritable, having poor co-ordination or suffering from heartburn.
Sometimes your partner might be more aware of your snoring and pauses in your breathing than you are.
If you think you may be suffering from obstructive sleep apnoea, talk to your GP. They will ask about your symptoms, your health and your medical history, and about how sleepy you are when awake.
