Some patients need to have swallowing tests. They can choke or aspirate. Thats why returning to the world of eating is something that should be done very gradually.

Funny, we all eat the same things. I used to eat won ton soup like crazy, not right away cuz it burned my mouth. But after several months post rad I was living on won ton soup, yogurt, pudding and applesauce. Unfortunately, Im still at that same level several years later but thats due to my own issues. Its unusual, most people are able to return to eating very gradually.

Best of luck with your husband trying to eat again. It will take lots of time for him to eat a tiny amount and it wont taste very good for a while. He will get there, the worst is over
