10. Celiac Disease
A hereditary gluten intolerance which attacks the small intestine is Celiac disease. Since it is hereditary, this means it runs in the family and passed down from generation to generation. If this Celiac disease is not spotted at the first sign of symptoms and treated, this could lead to dehydration and malnutrition. It has become so common that there is now a Celiac Disease Foundation where you can find a wealth of information.
