Hello,
Thank you for your query.
As one's body ages, the compensatory mechanisms which take place in our body all the time also become weak. This is the process of aging.
However if your father doesn't have any symptoms like faiting, sweating or
dizziness while changing positions, it is unlikely to be a cause of concern.
His weakness could be due to
depression or he feels his time is running out.
I suggest you talk to him and visit your doctor to have a general checkup and understanding of his current condition.
- blood tests (
complete blood count, renal and
kidney function tests)
Based on clinical examination, further tests, if necessary
Medications may help but not always. Talking to him is best. Maybe he wants something else..
A change of scene may help.
Hope this helps. Please let me know if there is anything I can help you with.
Wish you both good health
