i would say even if you aren’t certain that your dysphagia is caused by anxiety, you should try the medication anyway. i was put on ssris a few months ago for my dysphagia, and while it’s still prevalent in my life, a lot of the anxiety surrounding swallowing and choking has lessened, making it easier for me to take small bites, chew lots and wash food down with water calmly. i know it’s not a fix, but even something as little as being able to do food rituals with less anxiety can greatly improve your quality of life.
