Am 70yrs. i had bad depresion for 14 month, eat once daily and sleep 3 hrs. does that cause macrocytic anemia. b12, folic ok. can it be bad absorption?

Yes.: I may have answered this already .Depression can cause poor appetite and may cause malnutrition over a long period of time . However if your B12 and Folic Acid are normal, then I do not believe you have macrocytic anemia. The cause of macrocytic anemia is due to the absence of intrinsic factor in your stomach causing malabsorption of nutrients that can cause macrocytic anemia.
