Thanks for contacting HCM
I am sorry to hear about your father and his failing health. from what you are describing
hearing loss is a natural consequence of aging and is not reversible. He can use
hearing aid to help improve some of the loss but the overall loss of hearing is inevitable.
Your father's loss of appetite and taste also comes along with aging but has some additional causes and I recommend that he see his doctor for additional testing. There are some metabolic changes like
anemia, vitamin deficiencies and possible strokes that may affect his taste.
The frequent falls is of great concern because one of those falls could result in significant
injury. With this many problems I strongly recommend he see his doctor and that he/she run appropriate tests to determine and help prevent further falls.
The last thing you mention is his memory and at 83 years old
memory loss is common. As I mentioned above I believe you need to have your father seen and examined by his doctor.
Hope this answers your question. Please contact us again with any of your questions.
