You mention "dizzyness". This may be orthostatic hypotension. Does this happen when he stands up quickly? I had this for a while when I was on both Parkinson's drugs and drugs to reduce my blood pressure. Together, they were lowering the blood pressure too much, I'd gone from hypertension to hypotension. In my case removing the blood pressure pill did the job. Get your dad to see his GP to see if this applies to him.

Watch out for dehydration. It's easier said than done, but make sure he's drinking enough.
