Celiac Disease

However, for some people – perhaps as many as 3 million Americans – a gluten free-diet is not a new weight-loss strategy but a necessary, lifelong treatment to relieve the often painful symptoms of celiac disease.

What is Celiac Disease? 

Celiac disease (also known as gluten-sensitive enteropathy, sprue, or coeliac) is an autoimmune disorder that affects the digestion of any food containing the protein gluten (e.g., wheat, rye, barley) and can lead to damage of the small intestine.

When a person with celiac disease digests even the smallest trace of gluten, their body sends an immune response that attacks the small intestine. These attacks then damage the villi, the small fingerlike projections that line the small intestine and absorb nutrients. Once the villi are damaged, nutrients can no longer be adequately absorbed by the body.

Causes 

The exact cause of celiac disease is not known, but there are several identified contributing factors, such as genetic interaction, digestion of large quantities of gluten, environmental factors, the age when gluten is introduced into a child’s diet, gastrointestinal infections, and gut bacteria. Another possibility is that celiac disease can be triggered by stress-induced events such as a surgery, pregnancy, viral infection, and severe emotional stress.

Risk Factors

There are certain factors that can increase your risk of developing this condition, such as type I diabetes, Down syndrome or Turner syndrome, autoimmune thyroid disease, microscopic colitis, Addison’s disease, or rheumatoid arthritis.

Symptoms

Symptoms can vary greatly and are quite different among adults and children.

For adults, many of the most common symptoms are related to digestive and gastrointestinal issues, such as diarrhea, bloating and gas, abdominal pain or cramping, nausea, constipation, vomiting, and possibly acid reflux and heartburn. Fatigue and weight loss are related and also very common.

Additionally, many adults may experience seemingly unrelated symptoms, such as:

For younger children under 2 years of age, the most common symptoms are:

For children 2 years and older, the most common symptoms are:

If you experience digestive discomfort or diarrhea that lasts for more than two weeks, you should consult your primary care clinician and have the symptoms evaluated. Consult your child’s pediatrician if he or she is pale, has stopped growing, has severe bloating and a distended belly, or has large, bulky stools.

Since celiac disease tends to run in families, inform your clinician if a first degree relative (mother, father, sister, brother) has been diagnosed with celiac disease so you can discuss whether you should be tested.

How is Celiac Disease Diagnosed? 

There are many blood tests available that can screen for celiac disease antibodies. The most commonly used procedure is the tTG-IgA class test. In order for this test to be as accurate as possible, you should not alter your diet and continue to consume gluten as usual in your diet.

If this test shows that you have signs of celiac disease you will need to receive a biopsy of your small intestine (endoscopic biopsy) to confirm the diagnosis. The endoscopic biopsy is performed by a gastroenterologist who takes a small tissue sample from your small intestine and to determine if there is damage that resembles celiac disease.

Treatment 

The only known treatment is following a strict gluten-free diet for the rest of your life. This removes the source of inflammation and allows the villi to regrow, healing the small intestine. Some people notice relief and symptom improvement right away, while for others, it can take years to fully heal.
