I am 75 yrs old, suffer from COPD , depression and adrelin insufficiency. Have been on prednisone , 20 mg per day for more than 6 months.(am reducing prednisone @ 1mg per month). for last 4 to 5 weeks have lost taste of foods. its difficult to eat adequately, which aggrevates my other health problems due lack of nurishment and weakness. is there a remedy for restoring tongue-taste, atleast partially?
Loss of taste to food can be because of depression, many medications particularly prednisolone that you are receiving etc. You may try : adequate treatment of depression adequately, wait till prednisolone is over, can take sips of soda in between your food bolus that may activate your taste buds.  But consulting your doctor all these issues and take a decision regarding prednisolone, particularly.
