Frequent Diarrhea And Celiac Disease: What's The Link?

Frequent Diarrhea And Celiac Disease: What’s The Link?

February 15, 2021

If diarrhoea is a frequent occurrence for you, it’s natural to be worried about what underlying health condition may be causing it. From irritable bowel syndrome to cancers, diarrhoea is a very common symptom. In this article, we shine the spotlight on celiac disease, an autoimmune disease in which consumption of gluten causes the body to attack the small intestine.

Celiac disease affects an estimated 1% of the worldwide population, and it is on an upward trend. This can also be seen by the rise in awareness of gluten-free food alternatives, and gluten-free-friendly eateries. As celiac disease is a serious condition that comes with a host of uncomfortable symptoms – including diarrhoea, it is important to watch out for the signs of it, so that it can be managed effectively for a better quality of life.

Does diarrhoea mean I have celiac disease?

As mentioned, diarrhoea doesn’t necessarily point to celiac disease. Diarrhoea is a symptom of a huge spectrum of diseases, or it could just be a one-off result of eating something wrong.

However, chronic diarrhoea could definitely be a sign of celiac disease. In fact, diarrhoea is one of the most common symptoms amongst celiac disease sufferers. One study found that diarrhoea was a symptom experienced by almost 80% of untreated celiac cases. The good news is, the percentage of patients who continued to experience chronic diarrhoea after treatment dropped significantly to 17%.

Diarrhoea in celiac disease is typically caused by impaired absorptive functions of the small intestine. It can manifest as watery stools, loose stools, or more frequent urges to go to the bathroom.

What other symptoms point to celiac disease?

Diarrhoea is only one of the many symptoms related to celiac disease. People with celiac disease may also experience the following symptoms:

  • Bloating & gas: Inflammation in the small intestine can contribute to excessive gas and bloating. One study found that 73% of celiac disease sufferers experienced bloated stomach symptoms before diagnosis.
  • Fatigue: Low energy levels are common in those with celiac disease. This is contributed by a higher incidence of sleep disorders in celiac patients, and nutrient deficiencies due to malabsorption.

Apart from the above, symptoms like stomach pain, unintended weight loss, and anaemia may also accompany celiac disease. If you are unsure if your diarrhoea is related to celiac disease, you can observe for these symptoms and observe if they worsen with increased gluten consumption.

How is celiac disease diagnosed?

If you suspect that you have celiac disease, your doctor can confirm the diagnosis using a few methods:

  • Blood tests: Two types of blood tests can help to diagnose celiac disease. One tests for the presence of certain antibodies, which are compounds produced by the body as an immune response to gluten. The other tests for certain antigens linked to celiac disease.
  • Biopsy: A small sample of tissue from the small intestine can help the doctor ascertain if you have celiac disease. In this case, the biopsy is usually obtained via an upper endoscopy, in which a long, flexible tube is inserted into the mouth, reaching past the throat into the small intestine.

How is celiac disease treated?

There is no direct cure for celiac disease, but most people manage their symptoms very well with a gluten-free diet. Going gluten-free gives your small intestine time to heal, and prevents additional damage to it.

Generally, you will have to avoid foods containing:

  • Wheat
  • Rye
  • Barley
  • Malt
  • Semolina

Additionally, it will require extra vigilance to identify and avoid gluten in processed foods and even medications, health supplements, and non-oral health products like toothpaste, mouthwash, and lipstick.

If celiac disease had caused significant deficiencies or anaemia, your doctor might also recommend certain supplements to maintain healthy levels of essential minerals in your body.

Conclusion

Although celiac disease can cause serious impacts on one’s health and quality of life, these symptoms are often well-managed with a conscientious diet.

However, if your diarrhoea turns out not to be celiac disease, it will be worthwhile to check up some other conditions to rule out other causes. A gastroenterologist can also advise you on the steps and tests you can take.
