Selective IgA Deficiency

Selective Immunoglobulin A (IgA) Deficiency is a condition where the body does not produce enough IgA, a type of antibody that plays a crucial role in the immune system, particularly in mucosal areas like the gut and respiratory tract. People with this deficiency may experience frequent infections, allergies, or autoimmune issues, as their immune defense is weaker in these regions. While many individuals may be asymptomatic, some can suffer recurrent health problems. Treatment generally focuses on managing symptoms and preventing infections rather than curing the deficiency, as there is no specific treatment to increase IgA levels.
