According to the charity, Parkinson’s UK, it can cause the muscles in a person’s jaw and face to be less efficient, which affects the control they have over chewing and swallowing.
“Less efficient muscles may also reduce the tightness that you have when closing your lips, making it hard to swallow,” said the health body.
Parkinson’s can also cause problems with tongue muscles.
As the charity explained: “The tongue is important in swallowing. We use it to move food around and push it to the back of the mouth to trigger the swallowing reflexes. Parkinson’s can also impair the reflexes that protect our windpipe from food and drink.”
