thank you so much for all your help and information its very helpful, mind blowing but helpful 

@rjane, yes, it often feels overwhelming in the beginning. But let me encourage you by saying that it will get easier. You and your husband will develop, over time, a sixth sense of how gluten is typically hidden in the food supply and where it is found and you will develop an inventory of foods that you can trust and to stock your pantry with. The largest risk involves eating out at restaurants. Even if you order things that are naturally gluten free, you have no control over cross contamination happening back in the kitchen in how things are prepared and handled. Another trap is eating at other people's homes who are trying to accommodate your husband's need to eat gluten free but who lack knowledge about how gluten may be hidden in the food supply. I mean, who would expect to find wheat in soy sauce or Campbell's tomato soup? I know you aren't going to want to hear this, but you may want to consider making your kitchen entirely gluten free to eliminate the possibility of accidents and cross contamination. It would also simplify your meal preparation. Yes, I'm talking about both of you eating gluten free in the home. Many couples find this is the easiest and most practical approach to being consistent and keeping their celiac loved one safe. You might find this helpful:  

I am not sure if they have tested him for SIBO  should I ask the hospital if they have tested him for that, there is so much to learn in the beginning I am not sure what or who to ask I am thinking the good folks on this site will help me, thanking you for your help  

Keep us posted.

Has your hubbie been checked for SIBO (Small Intestinal Bacterial Overgrowth)? This is not uncommon in the celiac population. https://my.clevelandclinic.org/health/diseases/21820-small-intestinal-bacterial-overgrowth-sibo
