If you have coeliac disease, it's crucial you don't eat any gluten. If you have untreated or undiagnosed coeliac disease and you're still eating gluten, several complications can occur.
It's a common misconception that eating a little gluten won't harm you. Eating even tiny amounts can trigger symptoms of coeliac disease and increase your risk of developing the complications outlined below.
Malabsorption (where your body doesn't fully absorb nutrients) can lead to a deficiency of certain vitamins and minerals. This can cause conditions such as:

As coeliac disease causes your digestive system to work less effectively, severe cases can sometimes lead to a critical lack of nutrients in your body. This is known as malnutrition, and can result in your body being unable to function normally or recover from wounds and infections.
If you have severe malnutrition, you may become fatigued, dizzy and confused. Your muscles may begin to waste away and you may find it difficult to keep warm. In children, malnutrition can cause stunted growth and delayed development.
Treatment for malnutrition usually involves increasing the number of calories in your diet and taking supplements.

If you have coeliac disease, you're more likely to also develop lactose intolerance, where your body lacks the enzyme to digest the milk sugar (lactose) found in dairy products. Lactose intolerance causes symptoms such as bloating, diarrhoea and abdominal discomfort.
Unlike gluten in coeliac disease, lactose doesn't damage your body. But you may get some gut-related symptoms when you eat foods containing lactose because you can't digest it properly.
Lactose intolerance can be effectively treated by not eating and drinking dairy products that contain lactose. You may also need to take calcium supplements – dairy products are an important source of calcium, so you'll need to compensate for not eating them.

Cancer is a very rare but serious complication of coeliac disease.
Someone with coeliac disease has a slightly increased risk of developing certain cancers. Recent research shows that this increased risk is less than previously thought.
If you've been following a gluten-free diet for three to five years, your risk of developing these types of cancer is the same as that of the general population.
