Disease: Celiac Disease
built 200 days ago
Celiac Disease may appear at any time in a person's life. The disease can be triggered for the first time after surgery, viral infection, severe emotional stress, pregnancy or childbirth. CD is a multi-system, multi-symptom disorder. Celiac Disease symptoms are extremely varied and can often mimic other bowel disorders. Infants, toddlers, and children often exhibit growth failure, vomiting, bloated abdomen and behavioral changes.

NIDDK-supported researchers are studying the genetic and environmental causes of celiac disease. In addition, researchers are studying the substances found in gluten that are believed to be responsible for the destruction of the immune system function, as happens in celiac disease. They are engineering enzymes designed to destroy these immunotoxic peptides. Researchers are ... developing educational materials for standardized medical training to raise awareness among healthcare providers. The hope is that increased understanding and awareness will lead to earlier diagnosis and treatment of celiac disease.
Screening for celiac disease involves testing asymptomatic people for the antibodies to gluten. Americans are not routinely screened for celiac disease. However, because celiac disease is hereditary, family members -- particularly first-degree relatives -- of people who have been diagnosed may need to be tested for the disease. About 10 percent of an affected person's first-degree relatives (parents, siblings, or children) will ... have the disease. The longer a person goes undiagnosed and untreated, the greater the chance of developing malnutrition and other complications.
Until recently, celiac disease was thought to be uncommon in the United States. However, studies have shown that celiac disease is very common. Recent findings estimate about 2 million people in the United States have celiac disease, or about 1 in 133 people. Among people who have a first-degree relative diagnosed with celiac disease, as many as 1 in 22 people may have the disease.
In Italy, where celiac disease is common, all children are screened by age 6 so that even asymptomatic disease is caught early. In addition, Italians of any age are tested for the disease as soon as they show symptoms. As a result of this vigilance, the time between when symptoms begin and the disease is diagnosed is usually only 2 to 3 weeks. In the United States, the time between the first symptoms and diagnosis averages about 10 years.
Adults who begin to be ill with celiac disease might have a general feeling of poor health, with fatigue, irritability and depression, even if they have few intestinal problems. One serious illness that often occurs is osteoporosis (loss of calcium from the bones). A symptom of osteoporosis may be nighttime bone pain. Also, about 5% of adults with celiac disease have anemia.
