The cough itself is typically a hoarse brassy ‘seal-like’ cough, due to TM. Some adults have persistent coughing; for others it arises post aspiration or infection and then subsides. Causes of persistent cough include airway reflux, excess or difficult-to-clear secretions, inflamed airways due to TM.
The cough can cause embarrassment, staring and comments in public due to its unusual nature – the TOF charity has produced explanatory badges as this is such a universal experience amongst those with OA/TOF.
It can also affect sleep, damage intercostal muscles, cause airway pain and fatigue, trigger vomiting and facial petechial bleeding due to raised pressure on the small vessels.
