Diarrhea
One of the first symptoms that many patients encounter before being diagnosed with celiac disease is loose, watery stools. According to one research, around 43% of celiac disease patients suffer diarrhea. This proportion is far lower than it was before the advent of blood tests, which are now extensively used to identify celiac disease.
Following a gluten-free diet, on the other hand, frequently eliminates many symptoms of celiac disease, including diarrhea. In fact, in one study of celiac disease patients, those who adhered to a gluten-free diet had considerably less diarrhea than those who did not. However, bear in mind that there are several other probable reasons for diarrhea, such as illness, dietary intolerances, or digestive problems.
