Coeliac disease is an autoimmune disorder of the small
intestine that occurs in genetically predisposed people of all ages from middle
infancy onward. Symptoms include chronic
diarrhoea, failure to thrive (in children), and fatigue, but these may be
absent, and symptoms in other organ systems have been described. Increasingly, diagnoses are being made in
asymptomatic persons as a result of increased screening; the condition is
thought to affect between 1 in 1,750 and 1 in 105 people in the United States. Coeliac disease is caused by a reaction to
gliadin, a prolamin (gluten protein) found in wheat, and similar proteins found
in the crops of the tribe Triticeae (which includes other common grains such as
barley and rye). Upon exposure to
gliadin, and specifically to three peptides found in prolamins, the enzyme
tissue transglutaminase modifies the protein, and the immune system
cross-reacts with the small-bowel tissue, causing an inflammatory reaction. That leads to a truncating of the villi lining
the small intestine (called villous atrophy).
This interferes with the
absorption of nutrients, because the intestinal villi are responsible for
absorption. The only known effective
treatment is a lifelong gluten-free diet. While the disease is caused by a reaction to
wheat proteins, it is not the same as wheat allergy. This condition has several other names,
including: cœliac disease eliac sprue, non-tropical sprue, endemic sprue,
gluten enteropathy or gluten-sensitive enteropathy, and gluten intolerance. The term coeliac derived from the Greek koiliakós
and was introduced in the 19th century in a translation of what is generally
regarded as an ancient Greek description of the disease by Aretaeus of
Cappadocia. Severe coeliac disease leads
to the characteristic symptoms of pale, loose and greasy stool (steatorrhoea),
and weight loss or failure to gain weight (in young children). People with milder coeliac disease may have
symptoms that are much more subtle and occur in other organs than the bowel
itself. It is also possible to have coeliac disease without any symptoms
whatsoever. Many adults with subtle
disease only have fatigue or anaemia. The diarrhoea
that is characteristic of coeliac disease is (chronic) pale,
voluminous and malodorous. Abdominal
pain and cramping, bloatedness with abdominal distension (thought to be due to
fermentative production of bowel gas) and mouth ulcers may
be present. As the bowel becomes more damaged, a degree of lactose intolerance may develop. Frequently, the symptoms are ascribed to irritable bowel syndrome (IBS), only later
to be recognised as coeliac disease a small proportion of patients with
symptoms of IBS have underlying coeliac disease, and screening for coeliac
disease is recommended for those with IBS symptoms. Coeliac disease leads to an increased risk of
both adenocarcinoma (small intestine cancer) and lymphoma
of the small bowel (enteropathy-associated T-cell
lymphoma or EATL). This risk
returns to baseline with diet. Longstanding and untreated disease may lead to
other complications, such as ulcerative jejunitis (ulcer formation of the small
bowel) and stricturing (narrowing as a result of scarring with obstruction of
the bowel). So as you can see celiac’s
disease can make you lose weight and make it hard for you to gain weight. And I think that I may have this disease.
