Gluten intolerance or non-celiac gluten sensitivity, as it is also known, shares some of the same symptoms as celiac disease but is a less severe condition. Gluten intolerance can still cause considerable discomfort, however, and people sometimes use lifestyle changes to try and manage its symptoms.
Gluten intolerance is often mistaken for celiac disease, but they are separate conditions. Celiac disease is a severe autoimmune disease, and it can damage a person’s digestive system.
The symptoms of gluten intolerance are less severe than celiac disease or a wheat allergy, and people know much less about the condition.
Seven symptoms of a gluten intolerance
Many of these symptoms occur shortly after consuming gluten. However, the exact combination of symptoms can vary
People who report gluten intolerance note the following symptoms as some of the most commonly occurring ones when they include glutenous foods in their usual diet.
1. Diarrhea and constipation
Symptoms of gluten intolerance may include constipation, fatigue, headaches, and nausea.
Those who report gluten intolerance say regular instances of diarrhea and constipation are a common symptom.
Occasionally having such digestive issues is normal, but experiencing them on most days can indicate an underlying condition.
People with celiac disease may also experience diarrhea and constipation. They may also have poop that smells particularly unpleasant, as the condition causes poor nutrient absorption.
Another very common symptom that people report in cases of gluten intolerance is bloating. This refers to the feeling of a full stomach that is uncomfortable and lasting. It is common also to feel a buildup of gas.
Over-eating is the most common reason for bloating, but it can happen for a number of different reasons. In people with gluten intolerance, the feeling of bloating may occur very regularly and is not necessarily related to the amount of food they eat.
3. Abdominal pain
Similarly, several different causes can lead to abdominal pain. But, again, those reporting gluten intolerance often note experiencing abdominal pain frequently and without another obvious reason.
Fatigue is another symptom that people may find hard to identify, as it can have a lot of different causes, many of which are not related to any medical condition.
People with gluten intolerance may have persistent feelings of tiredness that impair daily functioning.
People with gluten intolerance may also experience nausea, particularly after consuming a meal containing gluten. Nausea can have many causes, but if it often occurs after eating gluten it can be a sign of gluten intolerance.
Experiencing regular headaches is another symptom that can occur in people with gluten intolerance.
7. Other symptoms
People with gluten intolerance may experience several of these symptoms on a regular basis.
It is also possible for other symptoms to occur with gluten intolerance, although they are less common.
These may include:
- joint and muscle pain
- depression or anxiety
- severe abdominal pain
These are some common signs and symptoms of gluten allergy.
