You’ve noticed that you have a lot of stomach problems, like gas and diarrhea. And you feel tired, listless, and achy. And the symptoms worsen when you eat things like bread, pasta, and pastries. You’ve even lost a bit of weight and don’t know why.
A lot of things could be the reason. Celiac disease is one possibility. It’s an immune system problem. If you have it and eat a food that has gluten (a protein found in wheat, rye, and barley), your body attacks your small intestine. That causes damage and makes it hard for your body to absorb nutrients.
When you have celiac disease, your small intestine can’t properly digest nutrients from food. Over time, this can cause more health problems.
There are many different symptoms, and yours may be different from someone else’s. You may not even show signs of the disease at all.
