Is Iga High or Low in Celiac Disease?
Celiac disease is an autoimmune disorder in which the body’s immune system responds to gluten a protein found in wheat barley rye attacking damaging the lining of the small intestine. This damage inhibits the absorption of nutrients leading to numerous health problems ranging from malnutrition to chronic diarrhea abdominal pain fatigue.
One of the main diagnostic tools used in celiac disease testing is measuring the levels of immunoglobulin A (IgA) in the blood. IgA is an antibody that plays a vital role in the body’s immune defense system. In people with celiac disease IgA levels can either be high or low depending on various factors.
High IgA levels in celiac disease
In some cases people with celiac disease may have elevated levels of IgA in their blood a condition known as hypergammaglobulinemia or hyper-IgA. This is because the body’s immune system is constantly reacting to gluten in the intestine leading to increased IgA production.
However high IgA levels are not always present in celiac disease patients. In fact some people with celiac disease may have normal levels of IgA making it harder to diagnose the disease accurately. This is known as IgA deficiency.
Low IgA levels in celiac disease
In rare cases some people with celiac disease may have IgA deficiency meaning they don’t produce enough IgA. This can complicate celiac disease diagnosis because traditional testing for celiac disease relies on IgA levels. In these cases doctors may use alternative celiac disease testing methods such as measuring IgG antibodies or performing a small intestinal biopsy.
In summary IgA levels in celiac disease can either be high or low. Many factors influence IgA levels including gluten exposure genetics. While measuring IgA is a crucial step in celiac disease diagnosis not all celiac disease patients have high IgA levels. Therefore doctors must consider several factors to accurately diagnose the disease develop appropriate treatment plans.
