Hi,
Noted the history related to your 76 year old husband having one year problems of
dizziness, tingling in right hand (no tremors) occasional headaches, nausea, Cancer prostate with 33 radiations 9 years ago, on hormone treatment for 2 years,
gallbladder stones and polyp.
All these can surely give him easy fatigue.
The cause of the present symptoms may be due to the age and so many medical problems.
I would advise you the following:
Get the detailed blood investigations related to
hemoglobin, serum proteins, vitamins and so on so that the deficiencies if found can be corrected and he will be better.
Since
Parkinson is not there is a good news at the moment.
Start supplements.
Also anxiety and stress may be an added problems, have
counselling for this and be treated if required.
Change of place, outings, diet may help.
I hope this answer helps you. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant,
ENT & General Surgeon
