Have a belching problem doctor wants me on a non wheat and no foods with milk help its a delma don't know what product I can eat migh be hiatal hernia?

Good point. There are many causes for belching. A no wheat no milk diet can be an unnecessary inconvenience unless you are intolerant of gluten and lactose. Have tests been done to rule out other causes? If you have reflux esophagitis, sometimes called a hiatal hernia, there are more effective eats to solve your problem. Discuss this with your doctor, please, and good luck!
