Dear doctor, my father's age is 85, for the last 15 days he is suffering with the symptoms parkinson, he right hand and right leg is stiff while he is walking for his nature calls. Apart from that, two months back his prostate operation went well but for the last 3 days during in the night he went for several times passing the urine. It may lead to fluids loss. So consult the urology doctor, he is given natrise tab daily one and zanocin 400mg daily one. Using from yesterday night. Please suggest how to stop the urination during in the night and how to overcome this fluid loss or electrolytes. Please any specialist can give some advice. With regards.
