Can IgA Deficiency Increase Susceptibility to Chemical Sensitivities?
Yes, individuals with IgA deficiency may exhibit heightened sensitivity to certain chemicals due to impaired barrier function and immune surveillance. This increased sensitivity can lead to conditions such as multiple chemical sensitivity (MCS), where exposure to low levels of chemicals triggers adverse health effects. The exact mechanisms are not fully understood, but the lack of IgA may play a role in the exaggerated immune response.
