Hi,
Thanks for posting in HCM.
I understand your concern.
Based on your description, it appears that your dad has been treated mainly for infections.
However, other conditions associated with it could cause health detoriation. The extent of it cannot be predicted just based on your history.
Doctors might not be able to intervene at this stage due to his age and functioning status of his vital organs, which might not sustain procedures and thus might be risk to do that.
If investigations are done related to vital organs like lungs, heart,
liver and kidneys, it could be able to tell about the functioning status of them.
Kindly get the necessary investigations done and consult Physician with the report for evaluation and advise.
Hope the information provided would be helpful.
All the best.
Regards,
Dr.Ashakiran.S.
