A prescription can be offered for loss of appetite:
Megacesuspension 40 mg/ml, 240 cc bottles.
SIG: 15 mL q. day = 625 mg.
Megace ES, one bottle with 5 refills, 1 tsp qd = 625 mg/day.
We routinely check weight at initial consult, and weekly under therapy. No appetite usually leads to weight loss. Some tumors produce a hormone like substance called cachexin and food may taste differently due to alterations in zinc metabolism called dysgeusia. And oral and throat cancers may decrease normal saliva, and the resulting product can be nauseating and reduce appetite.
Ask your radiation oncologist. It may be treatment...or the disease, and there may be help.
