Prior to the start of treatment intake should be increased. If the patient is able to eat, then they should enjoy all their favorite foods even desserts. Bulking up before starting radiation or having surgery is a very good idea especially if the patient is on the average or slim side without having a alot of extra pounds.

During rads a patient should be taking in a minimum of 2500 or even 3000 calories every day. Water intake minimums are 48oz, but some will say much higher is necessary like 80 oz daily. This is one of the most important things that can be done. Its controllable in a whirlwind of things that are out of control. Its not easy to take this much in but it will help the patient get thru everything so much easier. As far as going into surgery, I would still advise it shouldnt hurt to add a couple pounds. This is especially true if the patient is having surgery on their mouth or throat making it difficult to eat regular foods. They should go into this without having any food or beverage cravings. Enjoy everything now as this will likely change.

Best wishes!
