Causes of Isolated IgA Deficiency:

  1. Genetics: Often, it’s inherited from your parents.
  2. Autoimmune Diseases: Conditions like lupus can lead to IgA deficiency.
  3. Medications: Certain drugs, like anti-seizure medications, may contribute.
  4. Infections: Some infections, like HIV, can lower IgA levels.
  5. Gastrointestinal Disorders: Conditions like celiac disease can be linked to IgA deficiency.
