Hi . I started yoga exercises and my swallowing problems seemed to disappear. It seems that sitting up straighter and breathing properly solved my problem

Hi
I’m a retired speech therapist. Get a swallowing study! Your speech therapist or dr can sched it. After that ask the speech therapist if results warrant therapy! The speech therapist can come to your home and give you lots of strategies and techniques such as:
Specific tongue exercises
Sit up 90% angle to eat
Small bites
Use “thick it” in liquids
Be aware of food temperature, texture, quantity

What I have been taught is that right before you swallow, pause for one second and tuck your chin to your chest. Then swallow. This technique works well for me.

Very definitely. See your Primary MD for a GI referral to get worked up and make sure it is from the Parkinson's. There are many other causes.
If it turns out to be from the Parkinson's, go online and look for a Speech Therapist that is trained in LSVT technique! I am a retired Gastroenterologist with Parkinson's and I had severe dysphasia early on. I saw a specially trained therapist in SF Bay Area, who, after a month of daily therapy and now visits about once s month and voice/swallowing exercises daily, she has me 80-90% better!
Please check it out!

Hello James D. I'm a former Hospice RN with PD. The dysphagia is common and I have also had episodes of the problem. The trick is to stay aware of chewing and swallowing, without becoming distracted while eating. Even knowing this there have been a few times when I drank or ate without paying attention and choked, once severely. Speech therapists can be useful particularly if there is an ongoing issue. Slow, purposeful chewing and swallowing is the key. My best wishes.
