Your stomach bloats

Frequent nausea

People with gluten intolerance and sensitivity, often experience nausea that’s frequent, persistent, and severe enough to make them feel like they may vomit. If you repeatedly feel nauseous, read on to see if you experience the other symptoms.
You get diarrhea

Gluten intolerance causes inflammation, irritation, and damage to the gut lining, in addition to poor nutrient absorption, resulting in digestive discomfort and diarrhea. Experiencing diarrhea too frequently is a major issue, potentially leading to dehydration, fatigue, and other health problems.
Depression

Leading to Celiac disease, a more severe form of gluten intolerance is associated with an increased risk of depression. Likely due to the social and financial burden of feeling ill, limited gluten-free menu options, and the fuss and expense of having to buy gluten-free food.
You experience joint pain

Individuals with gluten intolerance often describe it as a sudden stabbing, or a dull aching pain. If your joints are sore and you experience abdominal discomfort, you may well be gluten intolerant.
Other autoimmune disorders

The most severe form of gluten intolerance, celiac disease, is an autoimmune disease.
