11. Depression
Depression is pretty common worldwide and has been found to affect 6% of adults every year. But this condition is also a manifestation that you may have gluten intolerance, most especially celiac disease. There are many reasons behind this, such as the abnormal level of serotonin and the changes in gut microbiota.
12. Iron-Deficiency Anemia
As mentioned, people who have gluten intolerance may be suffering from iron-deficiency anemia, which explains the constant feeling of tiredness. Furthermore, this condition can also trigger other symptoms to develop, such as headaches, dizziness, shortness of breath, and low blood volume. If you have celiac disease, your small intestines will not be able to absorb nutrients well, which is why it can not absorb enough iron from the foods you eat.
