Meds or diseases: There are many reasons. Immune suppressant medications (e.g. steroids, azathioprine, mycophenolate), chemotherapy, certain seizure meds can all cause low antibody levels. Also, immune deficiencies like CVID lead to low levels. Certain infections like HIV can cause it, too. Excessive loss of protein from chronic diarrhea can cause it. Talk with an immunologist if you have more questions.
