Kennedy disease

Back to List of Questions
I have Kennedy disease. Lately, I've had trouble coughing up phlegm. I've also been hoarse and at times have a weak and raspy voice. An ENT told me two years ago that I have lost some elasticity in my larynx. Does Kennedy disease cause these types of problems?
While Kennedy disease does not impair the lungs themselves, the disease can weaken the muscles involved in breathing and coughing. As your respiratory muscles become weaker, you may find it more difficult to bring up phelgm and maintain clear airways.[1][2]

The Muscular Dystrophy Canada has developed a guide on respiratory care for people with neuromuscular disorders that gives further detailed information on this topic. You can view a PDF copy of this guide at the following link:
