Intolerance to gluten is incredibly common. The most complex form of intolerance to gluten is celiac disease. Celiac disease is an autoimmune condition. A 2014 study by Catassi et al. has shown that there has been a fivefold increase in the incidence of celiac disease in the UK over the past 25 years.

The number of children in the UK diagnosed with celiac disease has tripled over the past two decades. A 2015 study by Zingone et al. shows that there has been a 75% increase in the diagnosis rate for the disease between 2008-2012 compared to 1993-1997. 

However, not everyone suffers from a severe form of gluten intolerance. There’s a less severe form known as non-celiac gluten sensitivity, which can still be problematic. Both forms result in symptoms, many of which are unrelated to digestion.

Here are the common symptoms of gluten intolerance.


A person is said to suffer bloating when their tummy feels as if it is filled with gas or swollen after you’ve had a meal. Bloating is a common condition, but it may also indicate intolerance to gluten. It is worth noting that bloating is a VERY common complaint among individuals with intolerance or high sensitivity to gluten.

Bloating is caused when you consume a food for which your body can’t produce sufficient enzymes to break it down. In the absence of the appropriate enzymes, bacteria within the gut will break it down instead. When bacteria breaks down a food it produces a considerably higher amount of gas which the becomes trapped within the digestive system. Often it will hang around in the stomach causing the bloating sensation you may be struggling with.

Diarrhoea & constipation

Occasional episodes of constipation and diarrhoea are normal. However, one needs to do a checkup when it gets too frequent. Diarrhoea and constipation are common symptoms of gluten intolerance.

Gluten causes inflammation of the intestines in people with celiac disease or gluten intolerance. The inflammation damages the lining of the gut, leading to poor absorption of nutrients. The result is significant discomfort in the digestive system, constipation, and diarrhoea.

Abdominal pain

Abdominal pain is a common occurrence and can have many causes. Howstomach pain symptoms of gluten intoleranceever, it is also one of the most common symptoms of gluten intolerance. Studies have shown that at least 83% of people with gluten experience pains and discomfort in the abdomen after eating. The pain and discomfort you experience in the abdomen is, largely, due to the inflammation in the digestive tract and the excess gas trapped within it. 


Tiredness is a common experience and usually not associated with any disease. But then, if you are always feeling tired, there may be an underlying cause. Individuals who are intolerant to gluten are always prone to tiredness and fatigue, especially after eating gluten-rich foods.

Also, gluten intolerance may cause iron-deficiency anaemia, which also leads to tiredness and lethargy.

Unexplained weight loss

A drastic change in weight is usually a cause for concern. Although various factors may cause it, drastic weight loss is a significant side effect of gluten intolerance. If you’re eating gluten regularly and experiencing diarrhoea, then you’re causing your body to evacuate the food you’re consuming before it has the chance to absorb what it needs to from the food you’re eating. Various digestive symptoms, together with poor absorption of nutrients, may contribute to the loss in weight.
