Ask HN: My father is starting to lose his hearing. What should I do?
5 by edtech_dev | 2 comments on Hacker News.
My dad is in his mid 70s. He is otherwise very healthy, but has started showing signs of hearing loss. What steps can we take to prevent, reverse, or correct this issue? Seeing our family doctor and getting a hearing test, and perhaps a hearing aid seems like the obvious next step. But as great as modern medicine can be, there are gotchas because of incompetence or greed that you have to watch out for - for e.g. dentists pushing for unnecessary procedures to fund their next car or doctors prescribing nasal sprays that do more harm instead of treating the root cause etc. I am just trying to be cautious of going down the wrong path with this stuff. Given how insightful this community is, I thought I'd try posting here. Does anyone have any experience in this subject? What kind of a doctor/specialist/institute should we see? What are the best aids? Note: I'm in Canada
